Why you’ll love this recipe:

If you’re a fan of Funfetti desserts, birthday cake flavor, or cake mix cookies, this recipe is about to become a new favorite!

Imagine taking a buttery, flaky croissant and stuffing it with a soft Funfetti cookie filling made from boxed cake mix. As they bake, the filling turns into something that tastes like a warm cake mix cookie while the croissant becomes golden and crisp on the outside. The result is part croissant, part birthday cake, and part cookie—all in one incredibly easy dessert.

Funfetti Cookie Croissants are made by slicing open store-bought croissants and filling them with a Funfetti cookie dough mixture. The filling is made with boxed Funfetti cake mix, just like a classic cake mix cookie, which gives it that nostalgic birthday cake flavor everyone loves.

Once baked, the croissants become flaky and buttery while the filling stays soft, rich, and slightly chewy. Every bite tastes like a bakery-style pastry crossed with a warm Funfetti cookie!

Ingredients you’ll need:

Croissants- store-bought
Funfetti cake mix
Vegetable oil
Eggs
Rainbow sprinkles
Powdered sugar

The best part about this recipe is how easy it is! There is no homemade pastry dough, no complicated techniques, and no need to bake an entire cake. Store-bought croissants do all the heavy lifting, while the boxed cake mix creates a cookie filling in minutes.

If you’ve ever made cake mix cookies before, you’ll already understand why this filling works so well.

Boxed Funfetti cake mix creates a thick cookie dough that bakes up soft and chewy with very little effort. Instead of baking it on a cookie sheet, the dough gets tucked inside a croissant where it transforms into a gooey, birthday cake-inspired center.

The filling stays tender while the croissant turns crisp around the edges, creating the perfect contrast in every bite!

How to make the best Funfetti Cookie Croissants:

Preheat your oven to 350 degrees F and line a baking pan with parchment paper or a silicone baking mat.
Slice each croissant open lengthways, keeping the back side still intact so it opens like a book.
In a medium mixing bowl add the funfetti cake mix, oil and eggs then mix until well combined.
Scoop 1-2 tablespoons of the funfetti batter into each croissant, then press to close and spread the batter evenly.
Top each croissant with 1 tbsp of batter, then slightly flatten out each scoop and top with rainbow sprinkles.
Bake for 15 minutes, or until the topping is turning golden at the edges. Allow to cool slightly and dust with powdered sugar!

There are plenty of dessert recipes out there, but few combine three universally loved treats quite like these Funfetti Cookie Croissants. They have the buttery layers of a croissant, the nostalgic flavor of birthday cake, and the soft texture of a cake mix cookie all wrapped into one easy-to-make dessert.

One of the reasons these Funfetti Cookie Croissants are so popular is that they fit just about any occasion. They’re fun enough for birthday parties, easy enough for a weeknight dessert, and impressive enough to bring to a brunch or holiday gathering.

Because they’re made with simple ingredients, they’re also a great recipe to make when you’re craving something homemade but don’t want to spend hours in the kitchen.

They look festive, taste amazing, and come together with very little effort.

If you’ve been looking for a creative Funfetti dessert or an easy way to transform store-bought croissants into something special, these Funfetti Cookie Croissants are exactly what you need!

My top tips:

CROISSANTS: Use smaller sized, buttery croissants from a bakery section if possible rather than very large packaged ones. Day-old croissants often work better because they’re slightly firmer and hold the filling more easily. Also avoid croissants that are already filled or heavily glazed.
CAKE MIX: Use a cake-mix-based Funfetti batter. The cake mix creates a softer, fluffier cookie texture than traditional sugar cookie dough, so the filling ends up tasting like a warm birthday cake cookie tucked inside a buttery croissant. The contrast between the flaky pastry and the soft cake-batter-style center is what makes these so good!
TRIGGERED COOKIE SCOOP: I find it helpful to use a 1 tbsp triggered scoop to evenly portion the funfetti filling inside each croissant. About 1-2 tablespoons of batter per croissant is usually enough. Too much funfetti batter can remain raw in the center while the croissant overbrowns.
TOPPING: Topping these with extra sprinkles before baking and dusting with powdered sugar after baking are both completely optional! I will never say no to extra sprinkles, so I say go for it!
STORING: I recommend enjoying these cookie croissants day of for optimal freshness. For longer storage, freeze them on day one, then allow them to thaw at room temperature and warm them up right before serving. Croissant pastry is going to be stale by day 2 if you don’t freeze it.
