What is St. Patrick’s Day Brownie Trifle?
St. Patrick’s Day Brownie Trifle is a delightful layered dessert made with fudgy brownie chunks, green-tinted vanilla pudding, fluffy Cool Whip, and a crunchy topping of crushed Mint Oreos. Served in a clear glass trifle bowl (or individual cups if you’re feelin’ fancy), the layers create a fun, festive green-and-brown masterpiece that screams, “Kiss me, I made dessert!” What makes it stand out isn’t just its taste—it’s the texture party going on in every bite. You’ve got the rich, gooey brownie; the silky pudding dyed just the right shade of shamrock; and that cloud-like Cool Whip to bring it all together.
Plus, this isn’t a dessert that requires a culinary degree—if you can stir and layer, you’re golden. It’s the kind of recipe that’s flexible, too. Swap in pistachio pudding if you’re not into food coloring or go mini with individual servings for portion control (because we all know it’s hard to stop at one scoop).
Reasons to Try St. Patrick’s Day Brownie Trifle
First off, it’s ridiculously easy. We’re talking 30 minutes, no baking from scratch required, and you don’t need to hover over a stove while juggling your green outfit and wrangling kids. If you’ve ever had to whip up a last-minute treat for a classroom party or office potluck, you’ll appreciate how forgiving this recipe is. Secondly, it’s festive without being over-the-top.
The green pudding gives a perfect nod to St. Paddy’s Day without crossing into weirdly dyed food territory. Also, let’s not forget—it tastes amazing. Who can resist a mix of chocolate, pudding, and creaminess? No one. And because you can make it ahead of time, it’s a stress-free choice for entertaining. Not to mention, trifles always look impressive. No one has to know it started with a boxed brownie mix. If you’re hosting a full Irish dinner, this dessert is the easy win to cap off the night.
Ingredients Needed to Make St. Patrick’s Day Brownie Trifle
- 1 box Brownie Mix (plus the ingredients listed on the box, for an 8×8 pan)
- 3.5 oz Instant Vanilla Pudding Mix (use a large box for full-size trifle)
- 8 oz Cool Whip
- Green Food Coloring (or use pistachio pudding as an alternative)
- Mint Oreos, crushed
- Equipment: Mixing bowls, trifle bowl, electric hand mixer, Ziploc bag for crushing cookies
Instructions to Make St. Patrick’s Day Brownie Trifle
If you’re ready to whip up something festive, fun, and full of chocolatey goodness, let’s walk through how to make this St. Patrick’s Day Brownie Trifle step by step. Whether you’re a seasoned trifle queen or this is your first dessert layering adventure, these directions will guide you from boxed brownie mix to show-stopping green dessert with ease.
Step 1: Bake the Brownies
Start by preparing your brownie mix according to the instructions on the box (we’re using an 8×8-inch pan size here). Pour the batter into your greased pan and bake as directed. You want them fudgy and rich, not dry or overdone—so keep a close eye near the end. Once baked, let the brownies cool completely before moving on. If they’re even slightly warm, they’ll melt the pudding and whipped topping during layering (which, let’s be honest, will turn your pretty trifle into a chocolate puddle).

Step 2: Prepare the Green Pudding
While your brownies cool, let’s move on to the pudding. In a mixing bowl, whisk the instant vanilla pudding mix with cold milk as instructed on the box. Once it begins to set (this takes about 5 minutes), add green food coloring one drop at a time. Stir thoroughly between drops until you reach your desired shade of festive green. Don’t go full neon—think leprechaun, not alien.

Step 3: Crush the Mint Oreos
Time for a little stress relief. Place a handful of Mint Oreos (or regular if that’s what you have) in a Ziploc bag. Seal it tight, grab a rolling pin (or the bottom of a saucepan), and give those cookies a good smash. You don’t need to pulverize them into crumbs—aim for small chunks for some crunch on top. Set them aside for the final step.
👩🍳 Pro Tip: If you’re out of Oreos, crushed Thin Mints or Andes mints are tasty alternatives. Explore more creative topping ideas here.
Step 4: Cube the Brownies
Once your brownies are completely cool (we’re not taking any chances), use a sharp knife to slice them into bite-sized cubes. They don’t have to be perfect—rustic is beautiful in trifles. These brownie cubes are going to be your base layer, so make sure they’re small enough to layer easily but big enough to keep that chewy texture.
Step 5: Start Layering the Trifle
Grab your glass trifle bowl (or individual cups if you want mini versions). Begin the step by step trifle layering with a generous handful of brownie cubes. Press them gently into the bottom to form your first layer. Next, spoon in a thick layer of the green pudding and smooth it out with the back of your spoon.
After that, add a fluffy layer of Cool Whip—use a spatula for easy spreading. Repeat the process: brownies, pudding, Cool Whip. Depending on your bowl size, you’ll usually get two full layers of each.
Remember to save a little extra pudding and whipped topping for that picture-perfect finish.

Step 6: Top with Crushed Oreos and Chill
Now for the fun part: sprinkle the crushed Mint Oreos right over the top. Go heavy if you’re feeling indulgent—this is dessert, after all. You can also top with extra brownie bits or a light drizzle of chocolate syrup for flair.
Finally, cover the trifle and refrigerate for at least 1–2 hours before serving. This gives the layers time to settle and the flavors to meld beautifully. You can also make this dessert step by step up to one day in advance—just wait to add the crushed cookies until right before serving to keep them crunchy.

What to Serve with St. Patrick’s Day Brownie Trifle
This dessert pairs well with just about anything, but if you’re hosting a St. Paddy’s Day feast, balance the sweetness with some hearty Irish mains. Think corned beef and cabbage, Irish stew, or even a rich shepherd’s pie. Want to keep things cozy and casual? Serve it after something comforting like Easy Creamy Chicken Pot Pie or Cozy Cheeseburger Macaroni Soup. If you’re going for a sweet table spread, add some Birthday Cake Protein Balls or Valentine Day Swirl Cookies for a mix of flavors and textures.
Key Tips for Making St. Patrick’s Day Brownie Trifle
- Cool your brownies completely before layering to avoid melting the Cool Whip or pudding.
- Don’t overmix the pudding—it should be thick and creamy, not runny.
- For even layers, use a spoon or spatula to smooth each one before adding the next.
- Make it in mini trifle cups for individual servings—especially great for parties or picky kids.
- Want it richer? Add chocolate chips to the brownie batter or drizzle chocolate syrup between layers.
- For a fun twist, swap in Andes mints instead of Oreos. Trust me, it’s worth it.
Storage and Reheating Tips for St. Patrick’s Day Brownie Trifle
Okay, technically there’s no “reheating” with this one—but let’s talk storage. Cover the trifle tightly and store it in the refrigerator if you’re not serving it right away. It’s best eaten within 24 hours, but it will still taste great up to 3 days later. After that, the layers start to get a bit too cozy and can turn mushy. If you’re prepping ahead, keep the components separate and assemble the day you serve. Leftovers? Scoop ‘em into small containers for a treat-on-the-go—perfect for lunchboxes or midnight snacks.
FAQs
Can I make this trifle a day ahead?
Yes! In fact, it tastes even better after a few hours in the fridge. Just wait to add the crushed Oreos until right before serving to keep them crunchy.
What if I don’t want to use food coloring?
No problem—just use pistachio pudding instead of vanilla. It adds a naturally green color with a subtle nutty flavor.
Can I use homemade brownies?
Absolutely. If you’ve got a go-to recipe, use it. Just make sure they’re nice and fudgy so they hold their own in the layers.
Can I use whipped cream instead of Cool Whip?
Yes, but know that homemade whipped cream may deflate faster. For best results, stabilize it with a bit of powdered sugar or gelatin.
