Step 1

Preheat the oven to 350 degrees F. Line the bottom only of a 8- X 8-inch baking pan with parchment paper.

Step 2

In a medium bowl, add all crust ingredients. Beat using an electic hand mixer on medium speed until mixture resembles coarse crumbs.

Step 3

Pour mixture into prepared baking pan. Spread and press down evenly. Bake until edges are lightly browned, about 15 to 20 minutes.

Step 4

While the crust is baking, make the filling. In a medium bowl, add all filling ingredients. Beat using an electric mixer on low speed until well combined and scraping down sides of the bowl as needed.

Step 5

Pour the filling over the partially baked crust. Contine baking until filling is set, about 18 to 20 minutes. Sprinkle powdered sugar on top. Cool completely on a wire rack before cutting.

Step 6

Cut into rectangle bars or squares and serve immediately. Store in a sealed container at room temperature.
