Step-by-Step blueberry coffee crumb cake

1. Preheat the oven to 350°F (175°C). Grease and flour a 9×9 inch baking pan to ensure your cake comes out perfectly without sticking.
2. Cream together the softened butter and sugar in a mixing bowl until light and fluffy. This step is crucial for adding air, which will make your cake tender.
3. Add the eggs one at a time, mixing well after each addition. This method helps to incorporate the eggs fully, ensuring a smooth batter.
4. Stir in the milk and mix until combined, achieving a luscious, slightly thick batter that’s ready for the dry ingredients.
5. Whisk together 1 cup of all-purpose flour, 2 teaspoons of baking powder, and 1/2 teaspoon of salt in another bowl. This mixture will provide the structure for your blueberry coffee crumb cake.
6. Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Be careful not to overmix; you want a tender cake!
7. Fold in the fresh blueberries gently with a spatula to avoid breaking them apart and turning your batter blue!
8. Pour the batter into the prepared baking pan evenly, smoothing out the top with a spatula for an even bake.
For the Crumb Topping:
9. Combine 1 cup of all-purpose flour, 1/2 cup of granulated sugar, and 1 teaspoon of cinnamon in a separate bowl for that delightful crunch on top.
10. Pour in the melted butter and mix until crumbly, creating that irresistible topping that will contrast beautifully with your moist cake.
11. Sprinkle the crumb topping evenly over the cake batter, ensuring every bite will be deliciously buttery and sweet.

What if my cake comes out too dense?
If your blueberry coffee crumb cake turns out denser than expected, it might be due to overmixing the batter or using too much flour. Make sure to mix only until the ingredients are just combined and gently fold in the blueberries. This helps retain a light and airy texture.
