For the Cake:

- 3/4 cup granulated sugar
- 2 large eggs

- 1 cup sour cream (or Greek yogurt)
- 1 1/2 cups all-purpose flour

👩🍳 Instructions
1. Make the Crumble Topping
In a medium bowl, mix together flour, sugars, cinnamon, and salt. Stir in melted butter until the mixture forms coarse crumbs. Set aside.
2. Prepare the Cake Batter
Preheat your oven to 350°F (175°C). Grease and flour an 8×8-inch or 9×9-inch square baking pan.
In a large bowl, cream the softened butter and sugar until light and fluffy. Beat in eggs one at a time, then mix in vanilla and sour cream until smooth.
In another bowl, whisk together the flour, baking powder, baking soda, and salt. Gradually add dry ingredients to the wet mixture, stirring until just combined. Do not overmix.
Fold in the blueberries (and lemon zest if using) gently.
3. Assemble the Cake
Pour the batter into the prepared pan and smooth the top. Sprinkle the crumble topping evenly over the batter.
4. Bake
Bake for 40–45 minutes, or until a toothpick inserted in the center comes out clean. Let the cake cool in the pan for 10–15 minutes before slicing and serving.
💡 Tips for the Best Blueberry Crumble Cake
- Room temperature ingredients mix better and create a smoother batter.
- Coat blueberries with a little flour before adding to the batter to prevent sinking.
- Don’t overmix your batter or the cake may turn out dense.
- Store leftovers covered at room temperature for 2–3 days or refrigerate for up to a week.
🔄 Variations
- Make it lemony: Add lemon juice and zest to the batter for a blueberry lemon twist.
- Use other berries: Swap blueberries for raspberries, blackberries, or a mix of berries.
- Add nuts: Sprinkle chopped pecans or walnuts into the crumble topping.
- Glaze it: Drizzle a simple icing (powdered sugar + milk) on top after baking for added sweetness.
