These Fluffy Birthday Cake Sugar Cookies with Creamy Frosting Swirl taste just like a slice of birthday cake but in a soft, handheld cookie.

Top Reasons To Make It

Why should these cookies be your next baking project? Well, for starters, they’re incredibly fun to make. That moment you swirl the frosting on top is pure kitchen happiness. They’re also surprisingly straightforward, using simple ingredients you probably already have in your pantry. And let’s be honest, anything that combines the flavors of birthday cake and a soft sugar cookie is a guaranteed hit with kids and adults alike. They’re the perfect centerpiece for a party platter or a sweet ending to a weeknight dinner.

Ingredients

• 1 cup (2 sticks) unsalted butter, softened: For that rich, tender crumb.
• 1 ½ cups granulated sugar: Sweetens the cookie and helps create a slightly crisp edge.
• 2 large eggs, room temperature: Binds everything together and adds structure.
• 1 tablespoon vanilla extract: The key to that classic, warm sugar cookie flavor.
• 1 teaspoon almond extract: This is my secret weapon for that authentic “birthday cake” taste.
• 3 cups all-purpose flour: The foundation of our fluffy cookie.
• 1 teaspoon baking powder: Gives the cookies their signature lift and soft texture.
• ½ teaspoon baking soda: Helps with browning and a bit more rise.
• ½ teaspoon salt: Balances all the sweetness perfectly.
• ½ cup rainbow sprinkles: For that festive birthday party look and a fun little crunch.

For the Frosting:

• ½ cup (1 stick) unsalted butter, softened: The base for our creamy, spreadable frosting.
• 2 cups powdered sugar: Creates a smooth, sweet frosting that holds its shape.
• 2 tablespoons milk or non-dairy alternative: Thins the frosting to the perfect spreading consistency.
• 1 teaspoon vanilla extract: Echoes the flavor from the cookie.
• Pinch of salt: Cuts the sweetness and makes the flavor pop.
• Extra sprinkles for decorating: Because you can never have

Step By Step

1. Preheat your oven to 350°F (175°C) and line two large baking sheets with parchment paper.
2. In a large bowl, cream together the softened butter and granulated sugar with an electric mixer for about 2-3 minutes, until it’s light and fluffy.
3. Beat in the eggs, one at a time, followed by the vanilla and almond extracts. Scrape down the sides of the bowl to ensure everything is well mixed.
4. In a separate bowl, whisk together the flour, baking powder, baking soda, and salt.
5. Gradually add the dry ingredients to the wet ingredients, mixing on low speed until just combined. Be careful not to overmix!
6. Gently fold in the rainbow sprinkles with a spatula until they’re evenly distributed.
7. Using a medium cookie scoop (about 1.5 tablespoons), drop rounded balls of dough onto your prepared baking sheets, leaving about 2 inches between each cookie for spreading.
8. Bake for 9-11 minutes. The edges should be set and just barely starting to turn golden, but the centers will still look soft. Honestly, pulling them out when they look slightly underdone is the secret to a super soft cookie.
9. Let the cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.
10. While the cookies cool, make the frosting. Beat the softened butter until smooth. Gradually add the powdered sugar, milk, vanilla, and salt. Beat on medium-high speed for 2-3 minutes until it’s light and creamy.
11. Once the cookies are completely cool, swirl a generous dollop of frosting on top of each one. Finish with an extra pinch of sprinkles. So good.

Variations & Substitutions

Want to mix things up? For a funfetti vibe, swap the almond extract for a teaspoon of butter extract. If you need a gluten-free option, a 1:1 gluten-free baking flour works great here. You can also turn these into easy dessert recipes for different holidays—use red and green sprinkles for Christmas or pastels for Easter. For a dairy-free version, use plant-based butter and your favorite non-dairy milk. The frosting will be just as creamy and delicious.

Tips For Success

• Room temperature ingredients are non-negotiable for a perfectly creamy dough that bakes evenly.
• Don’t skip the parchment paper! It prevents sticking and makes cleanup a dream.
• Use a cookie scoop for uniformly sized cookies that all bake in the same amount of time.
• Underbake them slightly. Trust me, they’ll continue to set up on the hot pan as they cool.
• Let the cookies cool completely before frosting, or you’ll have a melty, delicious mess. Not that there’s anything wrong with that.
• Get the kids involved with the sprinkles. It’s the best part!

Baking Ideas For Special Occasions

These cookies are the ultimate canvas for fun cookie recipes for any event. Stack them high on a cake stand for a unique cookie “cake” at your next birthday party. Package them in clear cellophane bags tied with ribbon for lovely homemade party favors. They’re also fantastic baking ideas for bake sales, teacher appreciation week, or just because. Their cheerful appearance makes them a welcome addition to any dessert table.

Storage & Reheating

Store your frosted cookies in a single layer in an airtight container at room temperature for up to 3 days. If you need to stack them, place a piece of parchment paper between the layers to protect the frosting. You can also freeze the unfrosted baked cookies for up to 2 months; just thaw and frost when you’re ready to serve. The frosting itself can be stored in the fridge for a week—just let it come to room temperature and give it a quick stir before using.

Frequently Asked Questions

• • Can I make the dough ahead of time? Absolutely! You can chill the dough ball wrapped in plastic for up to 2 days. Let it sit at room temperature for 15 minutes before scooping and baking.
  • Why are my cookies flat? This usually means your butter was too warm or your baking soda/powder might be old. Check those expiration dates!
  • Are these a Crumbl cookie copycat? They’re inspired by that popular flavor, but I’ve worked to make a simpler, homier version you can easily whip up anytime.
  • What are some other unique cookie recipes I can try? If you love these, you might enjoy experimenting with other flavors like lemon poppyseed or brown butter snickerdoodles. The possibilities are endless!
