8. Stir in mini chocolate chips.
9. Press the cookie dough evenly over the cooled brownie base. Chill while preparing the fudge layer.

11. Remove from heat and add peppermint extract and food coloring if using.
12. Fold in mini chocolate chips or chopped chocolate.
13. Pour the fudge over the chilled cookie dough layer and spread evenly.
14. Chill the entire dessert in the refrigerator for at least 2 hours, or until firm enough to cut into squares.

FAQs

Can I use store-bought brownie mix?

Yes, you can replace the homemade brownie base with your favorite boxed mix to save time.

Is the cookie dough layer safe to eat?

Yes, it’s eggless and made with heat-treated flour to ensure it’s safe for consumption.

How do I heat-treat flour at home?

Spread the flour on a baking sheet and bake at 300°F (150°C) for 5–7 minutes, then let it cool before using.

Can I skip the cookie dough layer?

Yes, you can make just the brownie and fudge layers, but the cookie dough adds a delicious textural contrast.

Can I make the fudge layer mint-free?

Absolutely. Simply omit the peppermint extract and food coloring to make a classic white chocolate chip fudge.

Why did my fudge layer crack when cutting?

It may be too cold. Let it sit at room temperature for 10–15 minutes before slicing with a sharp knife.

What chocolate works best for the fudge layer?

Good-quality white chocolate chips or bars melt smoothly. Avoid candy melts for this layer.

Can I serve this at room temperature?

Yes, but it holds together better when slightly chilled, especially in warm environments.

How do I get clean cuts for serving?

Use a sharp knife and wipe it clean between each cut. Chilling the bars first also helps with precision.

Are these good for holiday gifts?

Definitely. Once chilled and cut, they hold their shape well in treat boxes or holiday tins.

Mint Chocolate Chip Fudge Squares layered over cookie dough and brownie crust are a decadent, multi-textured dessert perfect for the winter season. The layers complement each other beautifully, and the pop of mint brings a refreshing finish.
