  • 1/4 teaspoon ground cinnamon
  • 4 tablespoons unsalted butter, room temperature
  • 3/4 cup granulated sugar

Directions

Step 1 -Preheat the oven to 350 degrees F.

Step 2 -Coat an 8x8-inch square baking pan with nonstick spray.

Step 3 -In a small bowl, add 1/2 cup of the flour, the brown sugar, 1 teaspoon of the cinnamon, and 1/8 teaspoon of the salt and whisk to combine.

Step 4 -Add 4 tablespoons of the cold butter to the flour mixture and using your clean fingertips or a fork, rub the butter into the flour mixture until crumbly, forming a streusel.

Step 5 -Place the streusel mixture in the refrigerator.

Step 6 -In a medium bowl, add the remaining flour, the baking powder, the remaining salt, and the remaining cinnamon and whisk to combine.

Step 7 -In the bowl of a stand mixer or in a large mixing bowl using an electric hand mixer, add the remaining room temperature butter and the granulated sugar and beat on medium speed until smooth. Make sure to scrape down the sides of the bowl, as needed.

Step 8 -Add the egg and 1 1/2 teaspoons of the vanilla to the butter mixture and beat until combined.

Step 9 -Add the flour mixture and the buttermilk to the butter mixture, alternating between the two and adding about 1/3 of each at a time, and beat on low after each addition until combined. Make sure to start and end with the flour mixture and be careful not to overmix.

Step 10 -Add the peaches to the cake batter and gently stir to combine.

Step 11 -Pour the cake batter into the prepared baking pan, spreading it out evenly.

Step 12 -Top the cake batter evenly with the streusel mixture.

Step 13 -Bake until a toothpick or knife inserted into the center comes out clean and the cake is golden-brown, about 40-50 minutes.

Step 14 -In a medium bowl, add the confectioners' sugar, the heavy cream, and the remaining vanilla and whisk until smooth.

Step 15 -Drizzle the glaze mixture over the cooled cake.

Step 16 -Cut into squares and serve.
