Ingredients

• 2 cups white sugar
• 1 cup all-purpose flour
• 1 cup margarine, softened
• 3 eggs
• 4 (1 ounce) squares unsweetened chocolate
• 1 tablespoon vanilla extract
• 6 tablespoons butter
• 4 cups confectioners' sugar
• 6 drops green food coloring
• 2 tablespoons milk, or as needed
• 0.5 cup butter, softened
• 2.5 teaspoons vanilla extract
• 1.5 teaspoons peppermint extract
• 1.3333333730698 cups semisweet chocolate chips

Recipe Instructions

Step 1

Preheat the oven to 350 degrees F (175 degrees C). Grease a 9x13-inch baking dish.

Step 2

Place unsweetened chocolate in a microwave-safe cup or bowl. Heat in the microwave, stirring at 15-second intervals, until chocolate is smooth. Allow to cool slightly.

Step 3

Transfer melted chocolate to a large bowl. Stir in sugar and margarine until smooth. Beat in eggs one at a time until incorporated, then stir in 2 1/2 teaspoons vanilla. Stir in flour just until blended. Pour batter into the prepared dish and spread evenly.

Step 4

Bake in the preheated oven until the surface appears dry and the sides are beginning to pull away from the edges of the pan, 20 to 25 minutes. The brownies may look more like cake and may jiggle slightly in the center — this is normal. Remove from the oven and cool in the pan set over a wire rack.

Step 5

To make the middle layer, beat together confectioners' sugar and 1/2 cup butter in a large bowl with an electric mixer until well combined. Add milk as needed to get a spreadable consistency. Stir in peppermint extract and green food coloring until incorporated. Spread over the cooled pan of brownies. Refrigerate for 30 minutes.

Step 6

Place chocolate chips and 6 tablespoons butter in a microwave-safe bowl. Heat in the microwave until melted, stirring every 20 seconds until chocolate is smooth. Stir in 1 tablespoon vanilla until incorporated. Pour over chilled brownies and quickly spread to cover the surface. Cool again in the refrigerator until firm, about 10 minutes. Cut into squares and serve.
