Birthday Cake Lush: How It’s Done

Step 1: Prepare the Crust
Start by crushing the birthday cake-flavored Oreo cookies in a mixing bowl. You want them to be fine crumbs, so a food processor works great if you have one. Once crushed, pour in the melted butter and mix until everything is thoroughly combined. The mixture should resemble wet sand.
Step 2: Assemble the Crust
Press the Oreo mixture firmly into the bottom of a 9×13-inch baking dish. Make sure it’s even and compact for a sturdy base. Place the dish in the refrigerator while you prepare the filling.
Step 3: Make the Filling
In a separate mixing bowl, combine the vanilla instant pudding mix and dry Funfetti cake mix. Whisk them together for a few seconds. Next, add the milk and whisk until the mixture is smooth and thickened, about 2 minutes.
Step 4: Fold in the Cool Whip
Gently fold in half of the Cool Whip (8 ounces) into the pudding mixture. Be careful not to deflate the whipped cream too much; you want to keep the filling light and airy.
Step 5: Layer the Filling
Spread the pudding and Cool Whip mixture evenly over the crust in your baking dish. Smooth it out with a spatula to ensure it’s even.
Step 6: Add More Cool Whip
Top the pudding layer with the remaining Cool Whip (8 ounces). Spread it out gently to create a beautiful top layer.
Step 7: Finish with Sprinkles
Sprinkle the 1/3 cup of sprinkles evenly over the top layer of Cool Whip. For an extra festive touch, feel free to add more sprinkles if you’d like!
Step 8: Chill and Serve
Cover the baking dish with plastic wrap and refrigerate for at least 4 hours, or overnight for the best results. Once chilled, cut into squares and serve. Enjoy your delicious Birthday Cake Lush!
