What is crumb cake:

Crumb cake is a dessert made up of a rich and buttery yellow cake topped with a generous amount of chunky crumb topping then finished with a dusting of powdered sugar.

Crumb cake vs coffee cake:

Both cakes are similar, especially with the cake layer. The major difference is the amount of streusel topping. Coffee cake has less streusel topping and more cake. Crumb cake has a thicker and chunkier layer of streusel on top. A overhead view of a crumb cake cut into squares.

Why this recipe is so great:

  • Easy to make – Both the cake layer and crumb topping is made in one bowl and this whole dessert comes together in less than an hour.
  • Soft and moist cake layer – The cake layer is soft and moist, yet sturdy enough to hold all that chunky streusel on top. The vanilla-scented butter cake is not too sweet to counterbalance the amount of streusel topping.
  • Perfect crumb topping – The crumb topping is perfectly soft and tender to melt in your mouth, yet delicately crispy to create a nice contrast to the soft cake.

  • 1/3 cup (65g) granulated sugar

Instructions
