How to Make this Blueberry Crumb Cake

- Step 1: In a medium bowl, mix together flour, brown sugar and cinnamon. Add melted butter and stir until a crumb forms.
- Step 2: In another bowl, combine flour for the cake batter with baking soda, baking powder, and salt.
- Step 3: Beat together the unsalted butter and sugar in another large bowl until fluffy.
- Step 4: To the butter mixture, add eggs, vanilla, and sour cream then beat until combined.

- Step 5: Add the flour mixture to the wet ingredients in three batches until a thick batter forms.
- Step 6: Transfer the batter to a greased springform pan. Line the bottom with parchment for easier removal.
- Step 7: Sprinkle blueberries over the top of the cake batter.
- Step 8: Finish with the crumb topping, then bake at 350 degrees F for 50 to 55 minutes. Remove from the oven and cool for 20 to 30 minutes, then serve at room temperature.
Recipe Tips

- If you don't have a 9-inch springform, a 9x13 cake pan can also be used. You may need some extra blueberries to cover the top.
- In a pinch, you can use frozen blueberries instead of fresh. Be sure to thaw them ahead of time and drain any excess liquid.
- Keep an eye on the cake as it bakes. If it starts to brown too quickly, cover with some aluminum foil for the rest of the baking time.
- Use a toothpick inserted into the middle of the cake to check for doneness. If it comes out dry, it's good to go.

Recipe FAQ's
The topping of the cake is a simple mixture of butter, brown sugar, cinnamon and flour that forms a crumb-like consistency. This streusel topping adds lots of sweetness and warm flavor!
Overbaking is a likely reason for dryness, or too much flour was used in the batter. Be sure to measure it carefully. It might also help to allow the butter, sour cream, and eggs to come up to room temperature so they incorporate more easily into the batter.

Instructions

- Add the flour in three batches to the mixture and stir together each addition by hand using a heavy duty spatula until just combined. The batter will be thick like a biscuit dough.
- Scoop the batter into the prepared springform pan and using a wide spoon or spatula, press from the center to level out into an even layer. Top with the blueberries evenly over the cake mixture.

- If your crumb cake is starting to get too brown lightly place a piece of aluminium foil over the top.
