How to Make Crumbl Birthday Cake Cookies
Ready in under 30 minutes, these cookies are sure to impress your friends and family.
They're the kind of bakery-style treats that will have everyone asking for the recipe. Or maybe they'll just ask you to make another batch!
Luckily, they're super easy to make.
1. PREHEAT the oven to 350°F (175°C). Line two baking sheets with parchment paper or silicone mats.
2. BEAT the butter and sugar until light and fluffy. Scrape the bowl as needed, then blend in the eggs, one at a time, and the cake batter flavoring.
3. MIX in the flour and baking powder until just combined. Gently fold in the rainbow sprinkles with a spatula.
4. PORTION the dough into 1/3 cup balls. Flatten each into a 1-inch-thick hockey puck shape.
5. BAKE for 15-18 minutes, until the centers are puffed, edges are set, and tops are no longer glossy.
6. CREAM the butter, cream cheese, and cake batter flavoring until smooth. ADD powdered sugar, mixing on low, until fluffy. Add milk, if needed, to reach the desired consistency.
7. PIPE the frosting onto cooled cookies in a spiral pattern using a piping bag fitted with a large round tip.
8. SPRINKLE rainbow sprinkles over the frosting. Serve and enjoy!

Tips For the Best Crumbl Birthday Cake Cookies
These copycat Crumbl cookies are such a special treat. Each bite is like a party for your taste buds!
I love adding extra sprinkles for a festive finish. I’ve also picked up on these useful baking tips:
- Choose jimmies-style sprinkles. I recommend jimmies rather than nonpareils because they won't bleed into the dough.
- DIY flavoring. If you can’t find cake batter flavoring, use 1 1/2 teaspoons vanilla extract + 1/2 teaspoon almond extract to mimic the flavor. Take out 1/2 teaspoon of this mix for the frosting.
- Mix gently. Only mix the flour until just incorporated. Overmixing creates dense cookies. I usually do this by hand with a wooden spoon.
- Chill if needed. If your dough feels too soft, refrigerate it for 20-30 minutes before shaping.
- Flattening tip. When flattening the dough balls, use a flat-bottomed glass wrapped in plastic wrap to achieve uniform 1-inch thickness.
- Piping trick. No piping bag? No problem! Spread the frosting with a spatula for a more homemade touch. You can also use a zip-top bag with the corner cut off.
- Prep in advance. Make the dough up to 2 days ahead, wrap tightly, and refrigerate. Before baking, let it sit at room temperature for 10 minutes. You can also freeze unbaked dough balls for up to 3 months. Thaw slightly or bake frozen, adding 1-2 minutes.
- Try variations. Use seasonal or themed sprinkles to match holidays or celebrations, or try 1 cup mini white chocolate chips. Yum!

How to Store
For party prepping or keeping leftovers fresh, follow these storage tips:
To Store: Place the cookies in an airtight container and refrigerate for up to 5 days to keep the frosting fresh. Serve at room temperature for the best flavor and texture.
To Freeze: Freeze unfrosted cookies in a single layer on a baking sheet until firm, then transfer to a freezer-safe container or bag. Freeze for up to 3 months. Thaw the cookies at room temperature and frost before serving.
