It has everything people want in a cozy treat: a soft crumb, pockets of bright rhubarb, and a generous cinnamon topping that bakes into a golden, crumbly finish.

Rhubarb brings a lively tang that balances the richness of the cake, while the cinnamon streusel adds warmth and texture in every bite.

Why This Coffee Cake Works

A great coffee cake should be moist, tender, and easy to slice. This one checks all the boxes.

The rhubarb softens as it bakes, leaving juicy bursts throughout the cake without making it soggy. The streusel topping adds crunch and a caramel-like cinnamon flavor that contrasts beautifully with the tart fruit. It’s a classic cinnamon streusel cake with a seasonal twist.

Best of all, this is a practical brunch cake recipe. It’s baked in a 9×13 coffee cake pan, which means it’s easy to assemble, feeds a crowd, and cuts into neat squares for sharing.

What You’ll Need

You don’t need anything fancy to make this cake. Most of the ingredients are pantry staples, with rhubarb bringing the fresh flavor.

For the cake:

• All-purpose flour
• Baking powder and baking soda
• Salt
• Butter
• Granulated sugar
• Eggs
• Sour cream or yogurt
• Vanilla extract
• Chopped rhubarb

For the cinnamon streusel:

• Brown sugar
• Flour
• Ground cinnamon
• Butter
• A pinch of salt

Optional finishing touch:

• Powdered sugar for dusting

How to Make Rhubarb Coffee Cake

The process is simple and straightforward, which makes this an easy recipe to repeat all season long.

1. Prepare the streusel

Mix the brown sugar, flour, cinnamon, and salt. Cut in the butter until the mixture forms coarse crumbs. Set it aside while you make the batter.

2. Make the cake batter

Cream the butter and sugar together until light and fluffy. Beat in the eggs and vanilla, then stir in the sour cream. Add the dry ingredients and mix just until combined.

3. Fold in the rhubarb

Gently fold the chopped rhubarb into the batter. This keeps the pieces intact and helps distribute them evenly through the cake.

4. Assemble in a 9×13 pan

Spread the batter into a greased 9×13 coffee cake pan. Sprinkle the cinnamon streusel evenly over the top.

5. Bake until golden

Bake until the center is set and a toothpick comes out with just a few moist crumbs. Let the cake cool slightly before slicing so the crumb has time to settle.

Tips for the Best Rhubarb Coffee Cake

A few small details make a big difference in texture and flavor.

• Use fresh rhubarb when possible. It has the brightest flavor and best texture.
• Don’t overmix the batter. A light hand keeps the cake tender.
• Cut rhubarb into small pieces. Smaller chunks bake more evenly.
• Check for doneness carefully. The center should be baked through but still moist.
• Let it cool before slicing. This helps the streusel stay crisp and the cake hold together.

If your rhubarb is especially tart, you can lightly toss it with a spoonful of sugar before folding it in. That said, the contrast between sweet cake and tangy fruit is part of what makes this dessert so good.

Serving Ideas

This cake is wonderful warm, room temperature, or even chilled the next day. It makes an excellent brunch centerpiece, but it’s also just as welcome as an afternoon snack.

Try serving it with:

• Fresh coffee or espresso
• Whipped cream
• Vanilla yogurt
• A drizzle of glaze
• Fresh berries on the side

Because it’s baked in a 9×13 coffee cake format, it’s also easy to bring to potlucks, picnics, or holiday brunches. It travels well and slices cleanly, which makes it a reliable crowd-pleaser.
