- 1 cup sweetened condensed milk

Step-by-Step Instructions
Start by preparing your base layer. Crush chocolate cookies until they resemble fine crumbs, then mix them with melted butter, cocoa powder, and sugar. Stir until the mixture feels moist and uniform.
Press this cookie base firmly into a parchment-lined baking pan, using the back of a spoon or a flat cup to ensure even thickness. Place the pan in the refrigerator to chill while you prepare the mint layer, allowing the base to firm up and develop its structure.
In a large mixing bowl, beat softened butter until smooth and creamy. Add the sweetened condensed milk and continue mixing until fully combined. Slowly incorporate the powdered sugar, blending gradually so it doesn’t clump.
Add peppermint extract and a few drops of green food coloring, adjusting to your preferred shade. Continue mixing until the mixture becomes thick, smooth, and spreadable. This layer should resemble a thick frosting or a pliable dough.
Remove your chilled crust from the refrigerator and spread the mint mixture evenly over the cookie base. Use a spatula to smooth it out, ensuring the layer reaches all corners of the pan.
The mint filling should be firm enough to hold its shape but soft enough to blend into the base when sliced later. Place the pan back into the refrigerator to chill again while you create the chocolate topping. This helps the layers stay distinct and beautiful.
To make the chocolate topping, melt chocolate chips with butter in a microwave-safe bowl using 20–30 second intervals. Stir between each heating cycle until the mixture is completely smooth and glossy.
Pour the melted chocolate evenly over the chilled mint layer and spread it out gently with a spatula to create a smooth surface. Immediately sprinkle crushed candy canes and festive holiday sprinkles over the warm chocolate, pressing lightly so they adhere. Chill the entire slice for at least two hours before slicing into squares.
Expert Tips for Success
Make sure your base layer is packed tightly so it doesn’t crumble when slicing. Use a flat-bottomed glass to press the crust firmly into the pan.
When making the mint layer, sift powdered sugar first to avoid lumps that can disrupt the smoothness. Add food coloring sparingly—just a few drops go a long way in creating a vibrant holiday shade.
Allow each layer to chill fully before adding the next; this ensures clean, defined layers. If your chocolate begins to harden when spreading, warm it slightly to restore its smooth texture. Use peppermint extract, not mint extract, for an authentic candy cane flavor. When slicing, warm your knife under hot water, dry it, and press down firmly for clean edges.
Avoid overloading the topping with too many candy cane pieces; they can overpower the mint flavor. For best texture, use butter in the chocolate layer rather than oil. Store the slice in a single layer or between parchment sheets to prevent sticking. This dessert is best enjoyed chilled, so keep it refrigerated until serving.
Variations and Substitutions
Swap chocolate cookies for Oreos for a richer, sweeter crust. Add ¼ cup shredded coconut to the base for extra texture and flavor.
Replace chocolate chips with milk chocolate or white chocolate, depending on your preferred sweetness. Add a swirl of white chocolate over the top for a marbled festive effect.
Use red food coloring instead of green for a peppermint bark–inspired look. Mix crushed candy canes into the mint layer for added crunch.
Add mini marshmallows or chopped peppermint bark to the chocolate topping for a more decorative finish. For a gluten-free option, use gluten-free chocolate cookies in the crust. Add a teaspoon of vanilla extract to the mint filling for extra depth.
Serving Suggestions
Serve slices chilled, cut into small squares or bars for easy sharing. Add them to your holiday dessert platters alongside truffles, brownies, and cookies for a colorful display.
Pair them with hot cocoa, peppermint coffee, or mulled cider to complement the festive flavors. Wrap individual slices in cellophane bags tied with ribbon for holiday gifts or stocking stuffers.
Use them to create a holiday dessert board by pairing them with fruit, nuts, and chocolates. Add a few slices to lunchboxes for a special seasonal treat.
Display them on a tiered serving stand for Christmas parties—they add sparkle and color to any dessert spread. Serve with whipped cream or vanilla ice cream for a refreshing contrast to the rich chocolate.
Storage, Freezing, and Reheating
Store Minty Christmas Slice in an airtight container in the refrigerator for up to one week. Keeping it refrigerated preserves the layers and keeps the chocolate topping from melting.
To freeze, layer slices between sheets of parchment paper in a freezer-safe container and freeze for up to three months. Thaw in the refrigerator overnight before serving for best texture.
Avoid leaving the slice at room temperature for extended periods, especially near heat sources, since the chocolate topping can soften.
If stacking slices, place parchment between them to prevent sticking. Do not microwave frozen slices to thaw, as it may cause the layers to melt unevenly. Enjoy the slice directly from the fridge for the most satisfying cool, minty bite.
