Start by baking your brownies according to the package instructions in an 8x8-inch pan. Preheat your oven to the temperature indicated on the box, usually around 350°F (175°C). Once baked, let the brownies cool completely on a wire rack—this usually takes about 30-40 minutes. Make sure they are firm enough to cut into squares without falling apart.

While the brownies cool, prepare the instant vanilla pudding mix. In a medium bowl, combine the pudding mix with cold milk and whisk for 2 minutes until the mixture thickens. For a festive touch, add a few drops of green food coloring, stirring until you reach your desired shade of green. Set aside to allow it to firm up further while you move on to the next step.

Next, grab a package of mint Oreos to create that delightful crunch in the trifle. Place the Oreos in a Ziploc bag, seal it tightly, and use a rolling pin or any heavy object to crush them into fine crumbs. This should take about 2-3 minutes. Make sure to leave some larger pieces for texture, then set the crushed cookies aside.

Now it’s time to bring your St. Patrick’s Day Brownie Trifle to life! In a trifle bowl or individual dessert cups, begin layering with cut-up brownie squares. On top of the brownies, add a generous layer of the prepared vanilla pudding, followed by a layer of Cool Whip. Sprinkle a layer of crushed Oreos next, repeating the process until your bowl or cups are filled. Aim for at least three layers, finishing with a sprinkle of crushed Oreos on top for a gorgeous presentation.

Once assembled, cover the trifle with plastic wrap or a lid and refrigerate. It’s best to let it chill for at least one hour, allowing the flavors to meld beautifully. If you have time, letting it sit overnight will enhance the taste and texture even more, making your St. Patrick’s Day Brownie Trifle an unforgettable treat for your guests!
