Raspberry Coffee Cake

Directions

1. 1
   Prepare the streusel: I a medium bowl, whisk together 3/4 cup of the flour, 2/3 cup of the brown sugar, and 1/2 teaspoon of the salt.
2. 2
   Drizzle the 5 tablespoons of melted butter over the flour mixture and use a fork to distribute it evenly. Add the almonds and toss to combine. Squeeze the mixture into large clumps. Add 3/4 cup raspberries.
3. 3
   Prepare the cake: Preheat the oven to 350°F. Butter an 8-inch square baking dish and line it with parchment paper with a 2-inch overhang on two sides. In a medium bowl, whisk together the remaining 1 1/2 cups flour, the remaining 1/2 teaspoon salt, and 1 1/2 teaspoons baking powder.
4. 4
   In a large bowl, beat the remaining 10 tablespoons butter with the granulated sugar with an electric mixer on medium until fluffy, about 3 minutes. Beat in the egg and the vanilla.
5. 5
   Add half of the flour mixture and beat to combine. Beat in the buttermilk. Then beat in the remaining flour mixture. Fold in the remaining 1 cup raspberries.

   Transfer the batter to the prepared pan and smooth the top. Top with the crumb mixture. Bake the cake until a toothpick inserted into the center comes out with moist crumbs attached.

   Transfer the cake to a rack to cool completely. Use the parchment overhang to lift the cake out of the pan and transfer it to a cutting board or serving plate. Cut into 16 pieces to serve.
