How to Make blueberry coffee crumb cake

1. Preheat the oven to 350°F (175°C). Greasing and flouring a 9×13 inch baking pan ensures your cake will release beautifully after baking.
2. Whisk together the 2 cups of all-purpose flour, 1 cup of granulated sugar, 1 tablespoon of baking powder, and 1/2 teaspoon of salt in a mixing bowl until well combined.
3. Combine the melted 1/2 cup of unsalted butter, 1 cup of milk, 2 large eggs, and 1 teaspoon of vanilla extract in another bowl. Mix well to create a smooth mixture.
4. Pour the wet ingredients into the dry mixture and stir until just combined. Gently fold in the 2 cups of fresh blueberries (or frozen), taking care not to overmix.
5. Transfer the batter into the prepared baking pan, spreading it evenly for a consistent bake.
Make the Crumb Topping:
6. Mix together 1 cup of all-purpose flour, 1/2 cup of packed brown sugar, and 1 tablespoon of cinnamon in a separate bowl for a delightful topping.
7. Add cold cubed butter (1/2 cup) to your crumb mixture and mix until it becomes crumbly, resembling coarse sand with some larger chunks for texture.
8. Sprinkle the crumb topping evenly over the cake batter in the pan, creating that irresistible buttery layer we all crave.
Bake the Cake:
9. Bake in your preheated oven for 30-35 minutes, or until a toothpick inserted into the center comes out clean; it should be golden brown on top.
10. Cool in the pan for about 10 minutes before transferring to a wire rack to cool completely, filling your kitchen with delightful aromas.
Optional: Serve warm with a dusting of powdered sugar for an extra touch!

Tips for the Best blueberry coffee crumb cake
- Fresh Blueberries: Use fresh blueberries for better flavor and texture; if using frozen, ensure they are thawed and drained to avoid excess moisture.
- Proper Mixing: Don’t overmix your batter after adding the dry ingredients; mixing just until combined keeps your blueberry coffee crumb cake light and fluffy.
- Chill the Butter: For the crumb topping, make sure your butter is cold; this will create a delightful, buttery crumble that contrasts perfectly with the moist cake.
- Even Distribution: Gently fold in blueberries to avoid breaking them; this ensures even distribution throughout the cake without turning it purple.
- Bake Time Alert: Keep an eye on baking time; ovens vary, so check for doneness a few minutes early to prevent overbaking.
- Cooling Time: Allow your cake to cool in the pan before transferring it; this helps maintain its shape and prevents crumbling when serving.
How to Store and Freeze blueberry coffee crumb cake

- Fridge: If you want to keep it fresh longer, refrigerate the cake for up to a week. Be sure to wrap it tightly in plastic wrap or store it in a sealed container.

blueberry coffee crumb cake Your Way
Feel free to get creative with this delightful recipe—there are so many ways to personalize your favorite treat!
- Gluten-Free: Substitute all-purpose flour with a gluten-free blend for a deliciously moist cake that everyone can enjoy. Just make sure to use a blend that contains xanthan gum for the best texture.
- Nutty Addition: Swap half of the flour with almond flour for a subtle nutty flavor and a tender crumb. This variation not only adds depth but also a lovely richness that pairs perfectly with blueberries.
- Lemon Zest: Incorporate 1 tablespoon of fresh lemon zest into the batter for a bright, refreshing citrus note. This twist brings out the flavors of the blueberries and adds a delightful zing.
- Oat Crumb Topping: Replace all-purpose flour in the crumb topping with rolled oats for extra crunch and heartiness. The oats create a rustic texture that complements the softness of the cake beautifully.
