Instructions
Preheat the oven to 350 degrees. Coat a 9×13-inch baking pan with cooking spray.
To make the cake, in a large bowl, combine the flour, baking powder, baking soda, and salt. Mix well and set aside.
In the bowl of an electric mixer, beat the butter and granulated sugar together until well blended. Beat in the eggs, one at a time. Beat in the bananas and vanilla. Scrape down the sides of the bowl.
With the mixer on low speed, beat in half of the flour mixture. Beat in all of the buttermilk. Beat in the remaining flour mixture until just blended; don't overmix (small lumps are OK). Fold in the blueberries.
Transfer the batter into the prepared pan smooth the surface. Bake for 30 to 35 minutes, until a wooden pick comes out clean or with little moist bits clinging to it.
Cool the cake on a wire rack. Cool completely before glazing.
To make the glaze, whisk together all the ingredients until smooth. When the cake is cooled, drizzle the glaze over top.
Cut into squares and serve. Store leftovers in an airtight container for up to 4 days.
