Berry Streusel Coffee Cake


Scale

Ingredients

Streusel

  • 3/4 cup flour
  • 1/2 cup sugar
  • 1/2 cup light brown sugar
  • 1 tsp cinnamon
  • 1/4 tsp salt
  • 6 Tbsp unsalted butter, melted

Cake

  • 1 1/2 cups flour
  • 1 tsp baking powder
  • 1/2 tsp baking soda
  • 1/4 tsp salt
  • 6 Tbsp unsalted butter, at room temperature
  • 3/4 cup sugar
  • 1 1/2 tsp vanilla extract
  • 1 large egg plus 1 egg yolk, at room temperature
  • 2/3 cup plain fat-free Greek yogurt, at room temperature
  • 1/3 cup low-fat buttermilk, at room temperature
  • 1/4 cup blackberry preserves
  • 1 1/2 cups fresh berries

Instructions

  1. Preheat oven to 350°F and spray an 8-inch square baking pan with nonstick spray; dust lightly with flour.
  2. For the streusel, whisk together flour, sugar, brown sugar, cinnamon, and salt in a medium bowl. Add melted butter and mix in with a fork until completely incorporated and streusel is crumbly. Chill until ready to use.
  3. For the cake, whisk together flour, baking powder, baking soda, and salt in a medium bowl. Beat butter, sugar, and vanilla in a large mixer bowl at medium speed until light and fluffy. Add egg and yolk one at a time and beat well. Combine yogurt and buttermilk in a small bowl. Reduce speed to low and add flour mixture in three additions, alternating with yogurt mixture (begin and end with flour mixture).
  4. Spoon batter into prepared pan and smooth with an offset spatula. Tap sharply to reduce air bubbles. Drop spoonfuls of blackberry preserves over batter and gently spread into a thin layer with an offset spatula. Top with berries, pressing gently into the jam. Sprinkle evenly with chilled streusel.
  5. Bake for 60 to 65 minutes or until coffee cake is golden, springs back to the touch, and a toothpick inserted in the center comes out clean (start testing after 50 minutes; baking time will vary based on moisture from the berries). Cool in pan on a wire rack for at least 1 hour before serving.

Notes

Fresh berries – I used a blend of fresh raspberries, blackberries, and blueberries. Use any mix of fresh berries in this recipe.
