When the weather starts to cool and the first pumpkins appear at the market, it’s the small bakes that feel most satisfying. Not the showstoppers or layer cakes that require stamina and a stand mixer, but a simple, generous square you can cut right from the pan. This pumpkin chocolate chip snacking cake belongs firmly in that camp: soft, evenly spiced, moist from the pumpkin and sour cream, with pockets of chocolate that melt as you go.
You can make this cake with one bowl, a whisk, and a spatula. The batter doesn’t rely on creaming or complicated steps, and it stays tender for days. It tastes slightly better on the second day, when the flavors settle and the edges soften. It’s just as comfortable at breakfast with coffee as it is after dinner.
This recipe is written for an 8×8-inch pan, the size that sits right in the middle of weeknight and weekend baking. It’s the scale that says “enough to share, but not too much,” fitting nicely into a home baker’s rhythm—especially in the Pacific Northwest, where where cooler weather calls for kitchen projects, but life doesn’t slow down.
So if you’ve got a can of pumpkin puree on the counter or half a cup left over from a pie, this is the cake that gives it a second life. Let’s make it thoughtfully and simply, focusing on texture, flavor, and the kind of balance that keeps you coming back for another slice.
Why Make a Snacking Cake Instead of a Layer Cake?
A snacking cake is meant to be easy. You don’t need frosting or layers, though a drizzle of glaze never hurts. The beauty is that it bakes and cools in the same pan, and you can store it there too. It’s an everyday cake—one that fits between meals or accompanies coffee without ceremony.
It also fits modern cooks in smaller households or those who prefer variety over volume. You get just enough cake to enjoy fresh, with maybe one square left to freeze or tuck in a lunchbox.
This pumpkin chocolate chip version also has a benefit that many fall cakes lack—it’s not too sweet. The earthy pumpkin, balanced spices, and gentle bitterness of dark chocolate offset the sugar perfectly. The cake itself is moist but not heavy, rich but not dense.
Equipment You’ll Need
This recipe doesn’t require anything you don’t already own.
- 8×8-inch metal or glass baking pan
- Large mixing bowl
- Medium bowl for dry ingredients
- Whisk and rubber spatula
- Measuring cups and spoons
- Kitchen scale (optional but helpful)
- Small saucepan or microwave-safe bowl (for melting butter)
- Cooling rack
If you only have a 9×9 pan, reduce the bake time slightly. The cake will be a little thinner, but the flavors will remain balanced.
Preparation and Bake Times
- Prep time: 20 minutes
- Bake time: 35 to 40 minutes
- Cooling time: 30 minutes before slicing
- Total time: about 1 hour 30 minutes including cooling
- Yield: 9 generous servings
Ingredients
All ingredients should be at room temperature, unless noted. Using both butter and oil keeps the crumb tender while giving the cake a richer flavor.
Dry Ingredients
- 1¾ cups (220 g) all-purpose flour
- 1½ teaspoons baking powder
- ½ teaspoon baking soda
- ½ teaspoon fine sea salt
- 2 teaspoons pumpkin pie spice (or 1½ tsp cinnamon, ¼ tsp ginger, ⅛ tsp nutmeg, ⅛ tsp cloves)
Wet Ingredients
- 6 tablespoons (85 g) unsalted butter, melted and slightly cooled
- 2 tablespoons (30 ml) vegetable or sunflower oil
- ¾ cup (150 g) light brown sugar, packed
- ¼ cup (50 g) granulated sugar
- 2 large eggs
- ¾ cup (180 g) canned pumpkin puree (not pumpkin pie filling)
- ¼ cup (60 g) full-fat sour cream or plain Greek yogurt
- 2 teaspoons pure vanilla extract
Chocolate and Optional Toppings
- ¾ cup (125 g) semi-sweet or dark chocolate chips
- Optional: coarse sugar or finely chopped nuts for sprinkling
Step-by-Step Instructions
1. Prepare the Pan and Preheat the Oven
Preheat your oven to 350°F (175°C). Butter or oil your 8×8-inch pan, then line it with parchment so you can lift the cake out after baking. Allow a little overhang on two sides. This keeps the edges tidy and makes cutting easier later.
2. Mix the Dry Ingredients
In a medium bowl, whisk together the flour, baking powder, baking soda, salt, and pumpkin pie spice. Make sure everything is evenly distributed; this prevents clumps of spice or uneven rise in the batter.
3. Combine the Wet Ingredients
In a large mixing bowl, whisk the melted butter with the oil, brown sugar, and granulated sugar until the mixture looks smooth and glossy. Whisk in the eggs one at a time, followed by the vanilla extract. Continue whisking until the mixture lightens slightly and looks uniform.
4. Add Pumpkin and Sour Cream
Whisk in the pumpkin puree and sour cream. The batter will look thick and a little grainy at first; keep whisking gently until smooth. This combination yields a moist crumb without feeling greasy.
Make sure your pumpkin puree is well-stirred before adding—it can separate in the can or container. If it looks watery, blot it briefly with a paper towel to avoid extra moisture.
5. Fold in the Dry Ingredients
Sprinkle the dry ingredients over the wet mixture, and use a rubber spatula to fold gently. Turn the bowl as you fold, scraping the sides and bottom each time to make sure no dry pockets remain. Stop mixing as soon as you no longer see streaks of flour. Overmixing creates a tougher texture.
6. Add Chocolate Chips
Fold in the chocolate chips. You can hold a few back to sprinkle on top before baking for an attractive look. Chocolate chunks work just as well if you chop a bar yourself.
7. Pour and Smooth the Batter
Transfer the batter to your prepared pan and smooth the top with a spatula. If using extra chocolate chips or coarse sugar, scatter them evenly over the surface.
The batter should be thick but spreadable, with a gentle sheen from the butter and oil.
8. Bake
Bake for 35 to 40 minutes, or until a toothpick inserted near the center comes out mostly clean with just a few moist crumbs. Rotate the pan halfway through baking to ensure even browning.
In glass pans, baking might take a few minutes longer. Avoid overbaking, as it can dry out the edges.
9. Cool the Cake
Set the pan on a cooling rack and let the cake rest for at least 30 minutes. If you try to cut it too soon, it may crumble while still warm. Once cooled, use the parchment to lift it out carefully, then cut into squares.
10. Optional Glaze or Serving Ideas
This cake doesn’t need frosting, but if you want to dress it up slightly, whisk together ½ cup powdered sugar with a few teaspoons of maple syrup or milk for a quick glaze and drizzle it over the cooled cake. A small scoop of vanilla ice cream beside a warm square is another easy option.
Texture and Flavor Notes
The crumb of this cake lands between a quick bread and a tender snack cake. It’s moist, with enough structure to hold a clean slice. The pumpkin brings color and softness without dominating the flavor, allowing the spices and chocolate to share the stage.
If you like a spicier cake, you can increase the cinnamon or ginger slightly. If you prefer more chocolate, adding another quarter cup of chips works fine, though it will make the cake a bit softer.
The brown sugar lends a slight caramel undertone, while the oil ensures that even once chilled, the cake won’t firm up unpleasantly. Each slice carries a balance of warmth, sweetness, and a gentle hint of bitterness from the chocolate—something that works as well with black coffee as with milk.
Storage and Freezing
Once completely cooled, store the cake at room temperature, covered, for up to three days. It stays moist and flavorful due to the pumpkin and oil.
For longer storage:
- Wrap individual pieces tightly in plastic wrap or a reusable container.
- Refrigerate for up to five days. Let them come to room temperature before serving.
- To freeze, wrap portions in parchment or freezer wrap, then seal in an airtight bag or container. Freeze up to two months.
Thaw at room temperature or gently warm slices in a low oven (300°F / 150°C) for about 8 to 10 minutes. The chocolate will soften again and the cake will regain its just-baked texture.
Adjustments and Variations
To Make a Larger Batch
To double the recipe, use a 9×13-inch pan and bake for 40 to 45 minutes. You may need to tent loosely with foil for the final ten minutes if the top starts to darken too early.
Substitute for Sour Cream
If you don’t have sour cream, plain Greek yogurt works nearly identically. In a pinch, use buttermilk, though the batter will be slightly thinner—reduce it by one tablespoon for balance.
If You Want It Dairy-Free
Use plant-based butter or margarine and replace sour cream with unsweetened coconut yogurt. The texture remains tender, and the faint coconut note blends well with pumpkin and spice.
Alternative Chocolate
Dark chocolate chips (60–70% cacao) deepen the flavor; milk chocolate adds creaminess and sweetness. For an even more complex taste, chopped chocolate from a bar melts more unevenly, giving small pockets of melted richness across the crumb.
Add Nuts or Seeds
If you like a bit of crunch, add half a cup of chopped toasted walnuts or pecans into the batter. Pumpkin seeds sprinkled over the top before baking keep a pleasant look and toasty flavor.
Serving Suggestions
This cake serves a purpose beyond dessert. It fits almost anywhere:
- Morning coffee: Slightly warmed, the chocolate melts and the spices bloom.
- Lunchbox treat: It’s sturdy enough to pack without frosting mess.
- Afternoon snack: Balanced and satisfying, not too heavy.
- Casual dessert: Add a drizzle of glaze or a spoonful of whipped cream.
It’s a cake that feels adaptable, a kind that doesn’t wait for an occasion.
For gatherings, cut into sixteen smaller squares; each person gets just enough richness without fatigue. For weeklong enjoyment, nine generous squares give a comfortable portion for families or couples who like a daily treat.

Troubleshooting
Cake Sinks in the Middle
Overmixing or underbaking are the most common causes. Make sure to whisk flour and leaveners well, avoid beating too much after adding flour, and check that your oven holds consistent heat.
Dense or Gummy Texture
Pumpkin puree can carry excess moisture. If it’s unusually watery, blot it lightly or measure by weight (180 g). Also, ensure baking powder and soda are not past expiration.
Dry Edges
This usually comes from overbaking or an oven running hot. If you notice this often, start checking at 32 minutes and use an oven thermometer to gauge accuracy.
Making It Your Own
Once you’ve baked this base recipe, you can adapt it countless ways. Try folding in ½ cup dried cranberries for a tart contrast or swirl in a spoon of cream cheese filling before baking. Sprinkle coarse sugar mixed with cinnamon on top for a lightly crisp crust.
You might also experiment with the shape—bake in muffin tins for portable snacks (15–18 minutes at 350°F). Or pour into a loaf pan for a more bread-like version, baking about 45 to 50 minutes.
Pumpkin blends generously with other purees too. Half sweet potato or carrot puree gives a milder flavor and brighter color. Each time, the same easy approach applies: whisk wet, fold dry, bake until just set.
The Appeal of Small-Square Cakes in Fall
There’s something about baking in fall that feels different from any other season. Maybe it’s the earlier twilight or the quiet after the rush of summer. Small-scale bakes like this speak to that rhythm—the kind where you want something fragrant in the oven but not so much that it lasts forever.
A single square pan is manageable in a home kitchen without needing special equipment. It fits easily in a weeknight routine and rewards you with the scent of cinnamon and nutmeg filling the air.
Pumpkin provides not just flavor but a natural moistness that keeps cakes soft longer than many fruit-based versions. Combined with chocolate, it bridges comfort and indulgence in a way that feels very Pacific Northwest: earthy yet rich, balanced, not flashy.
That’s why this recipe endures season after season. It offers familiarity and flexibility—not to impress but to enjoy.
How to Know When It’s Perfectly Done
Because this cake is moist, judging doneness can be tricky. Look for three signs:
- The edges pull just slightly from the pan.
- The top looks dry and softly springy.
- A toothpick comes out with a few tender crumbs, not wet batter.
If you prefer a gooier center (especially with extra chocolate), pull it out at the earliest sign of doneness; the residual heat will finish baking it gently.
Letting it cool in the pan for half an hour is key. The crumb sets up, becoming soft and sliceable without falling apart. Don’t rush it—it’s worth waiting for a cleaner, neater square.
A Note on Spices and Freshness
If your pumpkin pie spice blend has been sitting in a cabinet since last year, it might have lost some strength. To test, rub a pinch between your fingers. If it smells faint or dusty, shake up a fresh mix of ground cinnamon, nutmeg, and cloves. Whole spices ground just before use make a noticeable difference in the finished cake—more warmth, more fragrance, more depth.
Spices define the character of a fall bake, so don’t treat them as background noise. Measuring accurately and tasting thoughtfully makes all the difference between a cake that tastes like sugar and one that tastes like autumn.
Why Oil and Butter Work Together
Some cakes rely solely on butter, others on oil. Here they share the work: butter builds flavor and richness, while oil keeps moisture over time. Pure butter cakes firm up when chilled, but the touch of oil ensures this one stays tender even after a couple of days.
This combination makes the cake more forgiving. You can refrigerate leftovers without worrying they’ll dry out. When slightly warmed, the butter flavor resurfaces, especially under the chocolate chips, which re-soften beautifully.
When to Make This Cake
You can bake it year-round, but fall through early winter suits it best. The ingredients—pumpkin, brown sugar, cinnamon—reflect the cooler months, when kitchens welcome a warm oven.
It’s ideal for weekends, quiet holidays, or any weeknight when you want something satisfying that doesn’t demand a frosting spatula or precise timing. The batter mixes easily by hand, with no step requiring rush.
The result is steady and comforting—precisely what home baking should be.
Final Thoughts
Pumpkin and chocolate share a quiet harmony that doesn’t need much introduction. In this cake, they meet in simple balance: the pumpkin softens the crumb, the chocolate brings contrast, and the spices carry it all forward.
This 8×8 snacking cake asks little but gives a lot. It fits the kind of home baking that thrives in Oregon kitchens—straightforward, generous, and seasonal. Nothing fancy, just thoughtful ingredients turned warm and fragrant by the oven.
Cut a square while it’s still warm, watch the chocolate barely hold its shape, and you’ll understand why this is the sort of cake people bake again and again—not for occasion, but for comfort.
