How to make delicious blueberry crumb cake:

- Add the streusel topping: Once the streusel topping is mixed, sprinkle it all over the cake batter in an even layer.

Tips for baking this blueberry crumb cake recipe:
- Lightly coat the blueberries in flour before adding them to the batter. This prevents them from sinking to the bottom of the cake while it bakes.
- Don’t freak out over the consistency of the batter! This crumb cake batter is VERY thick. You’ll want to be sure to spread it out in the pan evenly before baking.
- Use cold butter for the streusel topping! If you use softened or melted butter, your streusel won’t be as crisp on top.
- Baking times may very. Every oven is different, and your cake may take a little longer to bake than mine did. No one likes an under-baked crumb cake so be sure a cake tester or toothpick inserted in the center comes out clean before removing the cake from the oven.
I love serving this delicious blueberry crumb cake with coffee, tea or even ice cream depending on the time of day!
Yes! Just be sure you add them to the batter completely frozen rather than thawed. Thawed blueberries are very soft and it would be hard to mix into the cake batter without squishing them al!
Definitely! Blackberries, raspberries and strawberries will all do the trick!
Yes! Both will add moisture and result in a very soft, tender cake.
Sure! Just double the amounts for all the ingredients and bake the crumb cake in a 9×13 baking dish. It’ll also have a longer baking time of about 50-55 minutes at 350 degrees F.
You can store the leftovers by either wrapping in plastic wrap and leaving at room temperature for us to 3 days, or store in the fridge for up to 4 days!
