Step‑by‑Step Instructions for Melted Jack O’ Lantern Brownies
Step 1: Prepare the Brownie Batter
Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking pan or line it with parchment paper. In a large mixing bowl, combine unsweetened cocoa powder, granulated sugar, melted butter, eggs, all-purpose flour, and salt. Stir until the mixture is smooth and well combined, forming a rich brownie batter that’s glossy and thick.
Step 2: Bake the Brownies
Pour the brownie batter into the prepared pan, spreading it evenly into the corners. Bake in your preheated oven for about 30 minutes. You’ll know they’re done when the edges are slightly puffed and the center is set but a bit soft, ensuring a fudgy texture for your Melted Jack O’ Lantern Brownies.
Step 3: Add Marshmallows
Once the brownies are baked, remove them from the oven and immediately top with an even layer of marshmallows. Return the brownies to the oven for an additional 5-7 minutes. The marshmallows should puff up and start to melt, creating that delicious “melted pumpkin” look that will be the star of this Halloween treat.
Step 4: Decorate with Candy Melts
After the marshmallows are perfectly melted, let the brownies cool slightly before decorating. Melt your orange candy melts in a microwave-safe bowl, heating in 30-second intervals until smooth. Drizzle the melted orange candy over the warm marshmallows, allowing it to create a festive design on your Melted Jack O’ Lantern Brownies.
Step 5: Add Fun Toppings
While the orange candy melt drizzle is still slightly warm, add candy eyes or chocolate chips to bring your jack-o’-lanterns to life! Press these decorations gently into the melted marshmallow to ensure they stick. Get creative with your designs, making your Melted Jack O’ Lantern Brownies as whimsical and fun as you desire!
Step 6: Cool and Slice
Allow the brownies to cool completely at room temperature before slicing them into squares. Use a sharp knife, wiping it clean between cuts for neat squares. These gooey Melted Jack O’ Lantern Brownies will have you delighting family and friends with every delicious bite, making them perfect for Halloween gatherings or cozy nights in.
