Ingredients Method Notes

Ingredients
  

  • 2 cups all-purpose flour (for cake)
  • 1 cup granulated sugar (for cake)
  • 2 teaspoons baking powder
  • 1/2 teaspoon salt
  • 1/2 cup unsalted butter, softened (for cake)
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 1 cup milk (whole or 2%)
  • 1 ½ cups fresh blueberries (or frozen, not thawed)
  • 1 tablespoon all-purpose flour (for dusting blueberries)
  • 1/2 cup granulated sugar (for streusel)
  • 1/4 cup all-purpose flour (for streusel)
  • 1/2 teaspoon ground cinnamon (for streusel)
  • 1/4 cup unsalted butter, cold and cubed (for streusel)

Method
 

  1. Prepare for Baking: Preheat your oven to 375°F (190°C). Grease and flour a 9x13 inch baking pan (or a 9-inch square pan for a thicker cake, adjusting baking time slightly).
  2. Make the Streusel: In a medium bowl, combine 1/2 cup granulated sugar, 1/4 cup all-purpose flour, and 1/2 teaspoon ground cinnamon. Add the cold, cubed butter. Using your fingertips or a pastry blender, cut the butter into the dry ingredients until the mixture resembles coarse crumbs. Set aside.
  3. Combine Dry Ingredients: In a large bowl, whisk together 2 cups all-purpose flour, 1 cup granulated sugar, 2 teaspoons baking powder, and 1/2 teaspoon salt. Make sure everything is well combined.
  4. Cream Wet Ingredients: In a separate medium bowl, beat the softened butter until creamy. Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract.
  5. Combine Wet and Dry: Gradually add the dry ingredients to the wet ingredients, alternating with the milk, beginning and ending with the dry ingredients. Mix until just combined. Be careful not to overmix; a few lumps are fine. Overmixing leads to a tough cake.
  6. Prepare Blueberries: In a small bowl, toss the fresh or frozen blueberries with 1 tablespoon of all-purpose flour. This helps prevent them from sinking to the bottom of your cake.
  7. Fold in Blueberries: Gently fold the floured blueberries into the cake batter. Use a spatula to avoid crushing them.
  8. Assemble and Bake: Pour the batter evenly into your prepared baking pan. Sprinkle the streusel topping generously over the batter.
  9. Bake: Bake for 35-45 minutes, or until a wooden skewer or toothpick inserted into the center of the cake comes out clean. The top should be golden brown and the streusel bubbly.
  10. Cool: Let the French Blueberry Coffee Cake cool in the pan on a wire rack for at least 15-20 minutes before slicing and serving. This allows the cake to set properly.

Notes

Do not overmix the batter to ensure a tender cake. Use room temperature ingredients for a smoother batter. Toss blueberries in flour to prevent sinking. Use cold butter for a crumbly streusel topping. Avoid opening the oven door too early during baking. Test for doneness with a clean skewer; do not over-bake. Allow the cake to cool in the pan for 15-20 minutes before slicing. Adjust baking time if using a different pan size.
Store leftover cake at room temperature in an airtight container for 2-3 days, or refrigerate for up to 5 days. The cake freezes beautifully for up to 3 months; thaw at room temperature. Reheat slices in the microwave (15-30 seconds) or toaster oven (300°F/150°C for 5-10 minutes) for a fresh experience.
Serve with coffee or tea, a fresh fruit salad, Greek yogurt, or as a decadent dessert with whipped cream or ice cream. Pairs well with orange juice or savory breakfast meats like bacon.
For variations, try other fruits like raspberries, use a 1:1 gluten-free baking blend for a gluten-free option, or plant-based milk and butter for a dairy-free option. Consider adding chopped nuts or citrus zest to the streusel or batter.
