How To Make No-Bake Cosmic Brownie Bars
Step 1: Prepare the Base Layer
- In a medium mixing bowl, combine the crushed chocolate graham crackers, melted butter, sugar, and cocoa powder.
- Mix until the texture resembles wet sand and is fully combined.
- Press the mixture firmly into an 8×8-inch baking dish lined with parchment paper. Use the back of a spoon or your hands to create an even layer. Refrigerate while preparing the fudge layer.
Step 2: Make the Fudge Layer
- In a microwave-safe bowl, combine the chocolate chips, sweetened condensed milk, and butter.
- Microwave in 20-second increments, stirring after each, until the mixture is smooth and fully melted.
- Pour the fudge mixture over the chilled base layer, spreading evenly with a spatula.
Step 3: Add the Cosmic Toppings
- Sprinkle the colorful chocolate candies or sprinkles evenly over the fudge layer while it is still soft.
- Gently press the toppings into the fudge to ensure they stick.
Step 4: Chill and Serve
- Refrigerate the bars for at least 2 hours or until fully set.
- Once firm, lift the bars out of the baking dish using the parchment paper. Slice into squares and serve!
