Prepare the Brownies: If making brownies from scratch, follow your chosen recipe to bake them. Allow the brownies to cool completely before cutting them into bite-sized squares for easy layering in the trifle.
Make the Chocolate Ganache: In a heatproof bowl, mix together the semi-sweet chocolate chips and heavy cream. Heat in the microwave at 30-second intervals, stirring after each interval until the mixture is smooth and fully melted. Set aside to cool slightly before using.
Whip the Cream: In a clean mixing bowl, combine the heavy whipping cream, powdered sugar, and peppermint extract. Using an electric mixer, beat the mixture until soft peaks begin to form. This will create a light and fluffy whipped cream.
Layer the Trifle: In a large glass trifle dish or individual serving cups, begin assembling your trifle. Start with a layer of brownie pieces, then add a layer of whipped cream. Drizzle a layer of chocolate ganache over the cream, followed by a sprinkle of crushed peppermint candies to add crunch and flavor.
Repeat the Layers: Continue to build your trifle by repeating the layers of brownies, whipped cream, ganache, and crushed peppermint candies until your vessel is full. Aim for the final layer to be a generous amount of whipped cream for a beautiful top.
Top it Off: Finish with a large dollop of whipped cream on the top layer. Add a rich drizzle of chocolate ganache and sprinkle additional crushed peppermint candies. If desired, add mini marshmallows for a fun twist that enhances the visual appeal.
Chill and Serve: Cover your trifle with plastic wrap and refrigerate for at least 2 hours. This chilling time allows all the delicious flavors to meld beautifully together.
