When I first made these Chocolate Mint Slice Bars, I didn't expect them to become a staple in my dessert repertoire. The flavor combination of rich chocolate and refreshing mint is simply divine! I experimented with different layers and ultimately settled on a silky mint cream sandwiched between a crunchy chocolate base and a glossy chocolate top. Each bite is a perfect balance of sweetness and freshness that I can't resist.

One tip I’ve found useful is to let the chocolate coating set in the refrigerator instead of at room temperature. This not only helps it harden faster but also gives it a nice snap when you bite into it. I love making these bars ahead of time for parties or just for myself—either way, they never last long!

Instructions

Follow these simple steps to create your Chocolate Mint Slice Bars.

Prepare the Base

In a mixing bowl, combine the crushed digestive biscuits, cocoa powder, and melted butter. Mix until well combined. Press the mixture firmly into a lined square baking pan to form the base.

Make the Mint Filling

In another bowl, beat together powdered sugar, softened butter, heavy cream, peppermint extract, and green food coloring. Spread this mixture evenly over the chocolate base.

Prepare the Chocolate Coating

Melt the dark chocolate and coconut oil together in a microwave or over a double boiler, stirring until smooth. Pour the chocolate mixture over the mint layer, smoothing it out with a spatula.

Chill and Serve

Refrigerate the bars for at least 1 hour or until the chocolate is set. Once chilled, cut into squares and enjoy!

These bars are sure to impress anyone who tries them!

Pro Tips

For a more intense chocolate flavor, consider using dark chocolate with a higher cocoa content. Also, feel free to adjust the amount of peppermint extract based on your taste preference.
