Step 1

Preheat the oven to 350F then line an 8x8 baking pan with parchment paper or foil. Set side.

Step 2

In a large bowl, cream the butter, granulated sugar, and brown sugar together until smooth and creamy. Add in the egg, almond extract (if using), and the vanilla extract, and mix to combine.

Step 3

Mix in the flour, baking powder, salt, and cornstarch just until the flour mixture barely disappears. Spread the batter into the prepared baking pan and bake in the preheated oven for 15 minutes. The center will still look raw but don't worry these bars will continue baking as they cool down.

Step 4

In a large bowl, whip the softened butter, and powdered sugar together until combined. Add in the heavy cream and vanilla and whip until light and fluffy.

Step 5

Frost the sugar cookie bars with that then top with sprinkles and eyeballs. slice and serve if you prefer your frosting on the softer side or chill them a bit to allow the frosting to set before enjoying.
