Better Than Yo Grandmas Crumb Cake


Crumb Top Layer:

  • 1 cup all purpose- flour
  • 1 tablespoon cinnamon
  • 1 cup brown sugar
  • 2 sticks melted butter (1 cup)

Cinnamon Center Layer:

  • 1/2 cup brown sugar
  • 1 tablespoon cinnamon


  • 1 stick butter (1/2 cup)
  • 1 cup sugar
  • 2 teaspoons vanilla
  • 2 eggs room temperature
  • 2 cups all-purpose flour
  • 1 teaspoon baking powder
  • 1 teaspoon baking soda
  • 1 cup sour cream


  1. First let’s make the crumb for our top layer. In a giant bowl combine flour, sugar, cinnamon and melted butter using a fork. Gently stir until pea size crumbs begin to form. Don’t overwork the mixture. Once done place in the fridge until ready to use later.
  2. Using a hand-mixer or Kitchenaid paddle attachment beat butter, vanilla extract and sugar on medium speed until light and fluffy. Scrape down sides of bowl with spatula. Add one egg at a time until combined. Scrape down sides of bowl in between. In a separate bowl whisk together flour, baking soda and baking powder. On low speed, alternate between adding the dry ingredients and sour cream. Starting with flour and ending with flour until batter is combined.
  3. Preheat oven to 350 degrees and line a 9×9 baking dish with parchment paper. Add 1/2 batter to your prepared baking dish and using an offset spatula smooth it out till every side is covered. The batter will be really thick- I promise this is the hardest part but just move slowly with it. Sprinkle 1/2 cup brown sugar on top of the batter and then add the cinnamon on top of the sugar. Pour remaining batter on top of cinnamon mixture and evenly spread across. Remove crumb layer from refrigerator and cover top of cake.
  4. Bake for 45-55 minutes or until the top of the cake springs back when you touch it. Once cooled sprinkle with powdered sugar!!
