There's something truly special about a slice of blueberry coffee cake paired with your morning cup of coffee. This recipe combines a tender, moist vanilla cake base with bursts of fresh blueberries and tops it all off with a buttery crumb topping that adds the perfect contrast of texture. It's the kind of cake that makes your kitchen smell absolutely incredible while it bakes.

What I love most about this coffee cake is how simple it is to throw together, yet it tastes like you spent hours in the kitchen. The key is using fresh blueberries, folding them in gently so they don't bleed into the batter, and that glorious crumb topping that bakes up golden and crunchy. Serve it warm from the oven with a generous cup of coffee, and you've got yourself a morning worth waking up for.

Ingredients

  • All-purpose flour:2 cups
  • Granulated sugar:¾ cup
  • Baking powder:2 tsp
  • Salt:¼ tsp
  • Unsalted butter, softened:½ cup
  • Large eggs:2 pieces

  • Vanilla extract:1 tsp
  • Fresh blueberries:1½ cups
  • Unsalted butter, cold:¼ cup
  • Brown sugar, packed:½ cup
  • All-purpose flour:½ cup

Instructions

  1. Preheat your oven to 350°F. Grease and flour a 9-inch square baking pan.

  4. Alternate adding the flour mixture and milk to the butter mixture, starting and ending with flour. Mix until just combined — don't overmix. Gently fold in the blueberries with a spatula.

  7. Bake for 35-40 minutes, until a toothpick inserted in the center comes out with just a few moist crumbs. The top should be golden brown.

Tips & Notes

  • Toss your fresh blueberries in a tablespoon of flour before folding them in — this helps prevent them from sinking to the bottom.
  • Don't overmix the batter once you add the flour mixture; overworking it will make the cake tough rather than tender.
  • For extra crumb topping flavor, add a pinch of nutmeg or a handful of chopped pecans to the streusel mixture.
  • This cake is best enjoyed fresh but keeps well covered at room temperature for 2-3 days.
