How to Make Cute Frankenstein Cookie Bars

First things first:

Preheat Your Oven!: Set your oven to 350°F (175°C). Prepare a baking pan with parchment paper, ensuring it hangs over the edges for easy removal later.

Cream Together Butter and Sugars!: In a large mixing bowl, beat together softened butter, granulated sugar, and brown sugar until creamy and well combined. The mixture should look light and fluffy.

Add Eggs!: Crack in those fresh eggs one at a time, mixing well after each addition until fully incorporated. You want that velvety texture!

Sift in Dry Ingredients!: Gradually combine flour, cocoa powder, baking powder, and salt into your batter. Mix gently until just combined; be careful not to overmix!

Spread Into Baking Pan!: Pour the batter into your prepared baking pan and spread evenly with a spatula. Resist eating it raw—though I won’t tell if you sneak a taste!

Bake Away!: Place in the preheated oven and bake for 25-30 minutes or until a toothpick comes out clean from the center. Let cool completely before frosting.

Now that you’ve conquered these steps, it’s time to transform these bars into adorable Frankensteins!

Strongly consider using vibrant green frosting as your finishing touch. Spread it generously over each cooled bar while letting your creativity run wild! Top with candy eyes—make sure they’re looking in different directions for extra cuteness.

Enjoy serving these charming treats at your next spooky gathering or simply indulge while watching some classic monster movies! Happy Halloween baking!
