Thin Mint Truffle Brownies, Made Easy

Step 1: Bake the Brownies
Start by baking your favorite brownie recipe in a 9×13 pan. Allow them to cool completely before proceeding. This step is crucial as we want a firm base for our truffles.
Step 2: Prepare the Cookie Layer
Crush the Thin Mint cookies into fine crumbs. You can use a food processor for this or place them in a zip-lock bag and crush them with a rolling pin. Set aside a handful of crumbs for garnishing later.
Step 3: Make the Cream Cheese Mixture
In a mixing bowl, combine the crushed Thin Mint cookies with the low-fat cream cheese. Mix until well blended and smooth. This will be your delicious truffle layer.
Step 4: Spread the Truffle Layer
Spread the cream cheese and cookie mixture evenly over the cooled brownies. Use a spatula to smooth it out, ensuring that it covers the entire surface.
Step 5: Melt the Chocolate
In a microwave-safe bowl, combine the chocolate chips and Crisco. Microwave in 30-second intervals, stirring in between, until the chocolate is fully melted and smooth.
Step 6: Pour the Chocolate Over the Truffles
Carefully pour the melted chocolate over the cream cheese layer, spreading it evenly with a spatula. Make sure to cover the entire surface for a beautiful finish.
Step 7: Chill and Set
Place the brownies in the refrigerator for at least 1 hour, or until the chocolate has set. This will help the layers meld together and make cutting easier.
Step 8: Serve and Enjoy
Once set, remove the brownies from the fridge and cut them into squares. Garnish with the reserved cookie crumbs for a delightful touch. Enjoy your Thin Mint Truffle Brownies with family and friends!
