Chef John's Blackberry Buckle

Ingredients

• 3 cups fresh blackberries
• 2 tablespoons white sugar
• 1 teaspoon vanilla extract

Instructions

1. 1

   Preheat the oven to 350 degrees F (175 degrees C).

2. 2

   Stir blackberries, 2 tablespoons sugar, and vanilla extract together in a bowl; let rest, 15 to 20 minutes.

3. 3

   Whisk flour, 3/4 cup sugar, almond meal, baking powder, salt, and cinnamon together in a bowl. Stir milk into flour mixture until batter is just combined.

4. 4

   Melt 6 tablespoons butter in a skillet over medium-high heat; pour into the bottom of an 8x12-inch baking dish. Pour batter on top of melted butter and use a spatula to gently distribute batter without mixing it into butter, leaving a 1-inch butter border around the sides of the dish.

5. 5

   Scatter blackberries over the batter and spoon any accumulated blackberry juices over the top.

6. 6

   Bake buckle in the preheated oven until crisped and browned around the edges, about 1 hour.

7. 7

   Melt remaining butter in a small skillet over medium-high heat. Cook and stir almonds in hot butter until golden brown and toasted, 2 to 3 minutes. Sprinkle toasted almonds over blackberry buckle and cool buckle to room temperature.
