St. Patrick Day Brownie Trifle started with a grocery aisle filled with green snacks and one curious kid asking for a dessert that looked like treasure. We didn’t have a set plan just a cart of Oreos, pudding mix, and plenty of ideas.
Back in the kitchen, Irish fiddle music played while we layered ingredients, switching between jokes and debates over pudding flavors. The brownies cooled while little hands crushed cookies and big hands stirred food coloring into vanilla cream.
We skipped anything too complicated and went straight to layering: rich brownie pieces, green-tinted pudding, soft Cool Whip, and crushed Mint Oreos. My mom arrived with gold-wrapped candies expecting cupcakes, but instead watched us fill a trifle bowl like it was a holiday art project.
The colors turned vibrant fast, and the mood shifted into something fun and shared, with spoons dipping in between laughs.
When we finally served the St. Patrick’s Day Brownie Trifle, it didn’t need explaining. The table quieted into that kind of focused tasting, followed by nudges for second helpings. For something made with no timeline and all instinct, it turned out layered, cheerful, and exactly what the day called for.

Cooking Instructions
Step 1: Bake the Brownies
Prepare the brownies according to the package directions using an 8×8 pan. Let them cool completely before cutting into bite-sized chunks.
Step 2: Make the Pudding
Whisk together the vanilla pudding mix and cold milk (as instructed on the box). Once set, stir in a few drops of green food coloring until you reach your desired festive shade.
Step 3: Crush the Oreos
Place several Mint Oreos in a Ziploc bag and crush with a rolling pin or the bottom of a cup until you get small chunks and crumbs.
Step 4: Assemble the Trifle
Layer half of the brownie pieces in the bottom of your trifle dish. Add a layer of green pudding, followed by a generous layer of Cool Whip. Repeat the layers with the remaining brownies and pudding. Top with more Cool Whip and finish with crushed Mint Oreos on top.
Step 5: Chill and Serve
Refrigerate for at least 1 hour before serving to allow layers to set and flavors to blend.

Mistakes to Avoid & Solutions
Brownies Not Cooled Before Cutting
Warm brownies will crumble and melt the pudding.
Solution: Let them cool fully before layering.
Over-whisking the Pudding
Too much whisking can make it overly thick or lumpy.
Solution: Follow box instructions and stop when smooth.
Crushing Oreos Too Fine
You want chunks, not dust.
Solution: Crush gently for texture variation.
Overuse of Food Coloring
Too much green can be overpowering.
Solution: Start with a few drops and add more only as needed.
Trifle Too Warm at Serving
Soft layers can slump if not properly chilled.
Solution: Refrigerate at least 1 hour before serving.
