  2. Prepare a 13”x18” pan by adding a layer of parchment paper. Top with the 4-cell Pan Extender and grease well, making sure to get the sides and corners.
  3. In a mixing bowl, beat 2 cups of butter, 2 ¼ cups light brown sugar, and white sugar until fluffy.
  4. Mix in the eggs one at a time.
  5. Beat in the sour cream and vanilla.
  6. In a separate bowl, combine dry ingredients (6 cups of flour, baking powder, and salt).
  7. Add the flour mixture to the wet ingredients in small portions, mixing until combined between each addition.
  8. Divide the batter in half, then spread one half evenly between the 4 cells. Be sure to spread the batter to the edges.
  9. Take the cinnamon sugar mixture and spread it evenly over the batter in all 4 cells.

  13. Bake for 75 minutes at 350 degrees F, or until a toothpick stuck into the center of the cake comes out clean.

Expert Tips for Making Cinnamon Crumb Cake

  • Allow the cold ingredients like the butter, eggs, and sour cream to come up to room temperature before adding to the batter. This will make it easier to combine them with the other ingredients and lead to a cake with the perfect moist consistency.
  • Finish off the cakes by dusting them with powdered sugar and some more cinnamon. You could also add a simple glaze of milk and powdered sugar, but this cake is plenty sweet without it.
  • Replace the sour cream with yogurt/Greek yogurt if that’s what you have on hand. The flavor difference isn’t noticeable and they’ll still provide the same moist texture.
  • Using the 4-cell Pan Extender is perfect if you sell baked goods or want to make a large quantity of mini cakes to give away as gifts. The finished mini cakes will be approximately 6”x9”x2.5”.
  • Be sure to spread out the batter and even the top to ensure that the cakes are all even.
  • Don’t lift the extender out of the pan too soon—give the cakes a bit of time to cool to ensure they won’t lose their shape or come apart.
