First Layer

Layering the Cups
  1. Remove the wraps from the Reese’s cups and place them in the dish, arranging in a grid pattern until all 24 cups are positioned.
Topping Layer

Notes

Avoid overmixing the dough after adding flour for better texture. For a richer experience, top with melted chocolate after cooling or add a sprinkle of sea salt before baking.
