Instructions
Step 1: Prepare the Brownies
Start by baking your brownies (or using a box mix if you’re in a hurry!). Once they are fully baked, allow them to cool completely before cutting them into small, bite-sized pieces. This step can be done ahead of time, so you can just grab them when you’re ready to assemble the trifle.
Step 2: Whip the Cream
In a large mixing bowl, combine the heavy whipping cream, powdered sugar, and vanilla extract. Using an electric mixer, whip the cream until soft peaks form. Add a drop or two of green food coloring and continue whipping until stiff peaks form. This will give you the perfectly light, green whipped cream for your trifle layers.
Step 3: Make the Mascarpone Layer
In a separate bowl, beat together the mascarpone cheese, cream cheese, sugar, and vanilla extract until smooth and creamy. You want it to be light and fluffy, so give it a good mix until the mixture is fully combined.
Step 4: Assemble the Trifle
Start by layering the brownie pieces at the bottom of a large glass trifle dish. Top the brownies with a layer of the mascarpone mixture, smoothing it out evenly. Then, add a layer of the green whipped cream. Repeat the layers until you’ve used all of your ingredients, ending with a final layer of whipped cream.
Step 5: Garnish
Finish off your trifle with a sprinkle of chocolate chips and green sprinkles on top for that extra festive touch. You can also add a few more brownie crumbles on top if you have any leftover.
Step 6: Chill and Serve
Cover your trifle and refrigerate it for at least 2-3 hours, or even better, overnight. This allows all the flavors to meld together and gives the dessert time to set. When you’re ready to serve, scoop out generous portions and enjoy the magic of this festive treat!
How to Serve St. Patrick’s Day Brownie Trifle
This dessert is perfect for serving at parties or family gatherings. Here are a few fun ways to serve it:
Individual Portions:
Scoop the trifle into individual glasses or small bowls for a more personal touch. This makes it easy for guests to grab their own serving without any mess!
Family-Style:
If you’re serving a crowd, the traditional large trifle bowl works beautifully. Just make sure you have plenty of spoons for everyone!
Toppings:
Add extra chocolate chips, whipped cream, or even a few chocolate shavings on top when serving for a little extra indulgence.
Additional Tips
Use Your Favorite Brownie Recipe:
Whether you make your brownies from scratch or use a box mix, make sure they’re rich and fudgy. The brownies provide a great base for the creamy layers.
Make It Ahead:
This dessert gets even better after sitting in the fridge for a few hours, so don’t hesitate to prepare it a day ahead of time. The longer it sits, the more the flavors blend together.
Customize the Colors:
While green is perfect for St. Patrick’s Day, you can easily swap in other colors for different occasions. Imagine a red, white, and blue trifle for the 4th of July or pastel shades for Easter!
Don’t Overwhip the Cream:
Be careful not to overwhip the cream! Once you’ve reached stiff peaks, stop whipping to avoid turning it into butter.
Use a Trifle Dish:
A glass trifle dish is perfect because it lets the beautiful layers shine. But if you don’t have one, a large clear bowl works just fine.
