Instructions
Brownie Batter
- Preheat the oven to 350F and grease and line an 8×8 square baking dish with parchment paper.
- In a measuring glass, combine the butter and chocolate. Microwave in 30 second intervals until smooth.
- In a large bowl using a hand or stand mixer with the whisk attachment, mix together the sugars and egg on high speed. Mix until it becomes pale and super smooth (about 3 minutes).
- Turn the mixer down to medium-low and trickle in the melted chocolate while mixing. Then mix in the vanilla.
- Once combined, pour in the flour, cornstarch, cocoa powder, and salt. Use a rubber spatula to mix the batter by hand, followed by the chocolate chips. Set aside.
Monster Cookie Dough
- In a medium bowl, combine the flour, oats, baking powder, and salt.
- In a large mixing bowl using a hand or stand mixer with the paddle attachment, mix together the peanut butter, butter, and sugars until smooth and well combined.
- Add in the vanilla and egg and mix on medium-high speed for about 2 minutes.
- Pour in the dry ingredients and use a rubber spatula to mix the dough together, followed by the chocolate chips and Reese’s pieces.
- To the baking pan, alternate adding spoonfuls of brownie batter and cookie dough. Then spread everything even. Sprinkle with a handful of chocolate chips and extra Reese’s pieces.
- Bake for 30-35 minutes. When the bars are fresh from the oven, stick little candy eyes to the melted chocolate chips on top.
- Allow the bars to cool for about 45 mins – 1 hour, then lift out, slice and enjoy!
