Step 2: Make the Brownie Batter
- Melt the baking chocolate in a microwave-safe bowl or using a double boiler. Let it cool slightly.

While brownies bake, prepare the mint layer:
1. In another bowl, mix vegan marshmallows Fluff, mint extract, and green food coloring until well combined. Adjust food coloring as needed for desired shade.
Step 5: Assemble Layers

Common Mistakes to Avoid
When making Triple Layer Fudgy Mint Oreo Brownies, it’s easy to make some common mistakes. Here’s what to watch out for:
-
Using the wrong size pan: Make sure to use a 9×13-inch pan for even baking. A different size can lead to undercooked or overcooked brownies.
-
Skipping the cooling time: Allow your brownies to cool completely before adding the mint layer. This helps the layers set properly and prevents melting.
-
Not measuring ingredients accurately: Be precise with your measurements, especially for the baking chocolate and flour. Use a kitchen scale if possible for best results.
-
Overmixing the batter: Mix just until combined. Overmixing can cause tough brownies rather than soft, fudgy ones.
-
Using cold ingredients: Let your butter and eggs reach room temperature before mixing. This helps create a smooth batter.
