What is a Crumb Cake?
It is one of the most delicious cakes you will ever have. It has a buttery sour cream base like a coffee cake and an extra-thick, generous layer of streusel crumb topping, hence the name crumb cake. This amazing cake is always a huge hit with family and friends. I like to serve it for brunch, but it is equally delicious any time of the day.
Ingredient Notes and Substitutions
See the complete list of ingredients below on the recipe card.
- Brown sugar: Use light brown sugar for a softer crumb.
- Butter: You can use unsalted or salted. If using salted butter, reduce the added salt to 1/4 teaspoon.
- Sour cream: For the best texture and flavor, use full-fat sour cream.
- Vanilla extract: Use the pure stuff for the best flavor.

In a medium bowl, stir together the flour, brown sugar, granulated sugar, cinnamon, and salt. Drizzle in the melted butter, stirring with a fork just until combined. Now, set it aside for a little bit.
Whisk the flour, baking powder, baking soda, and salt in a medium bowl. Use a hand or stand mixer on medium-high speed to beat the butter and granulated sugar until creamy and smooth. Reduce the speed to low and add the eggs one at a time, mixing just until combined. Mix in the sour cream and vanilla extract just until incorporated. Keeping the mixer on stir, add the flour mixture in three intervals, mixing just until combined.
Spoon the cake batter into a well-greased 9×13-inch baking dish. Use an offset spatula to spread the batter evenly. Sprinkle the crumb topping over the cake mixture and gently press it in – just a touch. Bake for about 45 minutes. Remove from the oven and let cool on a wire rack for at least 45 minutes before slicing.

Nice! The part about using sour cream in the batter is great 🙂 never tried that in a crumb cake before. Does it help keep the texture moist even after a day or two?
Beth Pierce
Yes it does!
