Instructions
For the Cake
  1. Preheat oven to 375°F. Grease a 9″ square baking dish.
  2. In a large bowl, cream butter and sugar with an electric mixer on medium speed until smooth, about 2 minutes. Add egg, buttermilk, salt and baking powder. Mix well, about 2 minutes, scraping down sides of bowl with a spatula as needed.
  3. On low speed, stir in the flour 1 cup at a time, until incorporated. Beat an additional 1 minute. Fold in blueberries, batter will be thick.
  4. Pour batter into greased pan and spread evenly with a spatula.
For the Topping
  1. In a small bowl, mix brown sugar, flour and cinnamon together. Add in butter, mixing until combined. Sprinkle topping mixture over the top of the cake batter, distributing evenly.
  2. Bake for 45-50 minutes, or until toothpick comes out clean from center. Let cool 1 hour before slicing. Store in an airtight container at room temperature for up to 3 days.
Recipe Notes
  • You can substitute buttermilk with regular milk if you don’t have any on hand, but buttermilk is what gives you the moist cake texture.
  • When checking for doneness, make sure a toothpick comes out clean from the cake center. The topping may look like it isn’t done as the butter melts in the oven, but it will firm up as it cools. I’ve made the mistake of overbaking because I thought the topping looked too soft, but it wound up too brown and too crunchy to cut into after it cooled.
