Crumbl Birthday Cake Cookies Copycat
These cookies are the kind you bake when you want a slice of celebration in cookie form. They come out soft in the center, with that familiar vanilla-cake flavor and rainbow confetti throughout. The cream-cheese–butter frosting gives the cookies a stable, slightly tangy top that holds the sprinkles in place and looks like a party crown.
I tested this recipe so that the process is straightforward and repeatable. Measurements, temperatures, and the order of steps are important—follow them and you’ll have consistent results: soft, tender cookies and a frosting that pipes cleanly without sliding off.
This post gives clear notes on ingredients, the exact step-by-step method, and practical tips for swapping, storing, and troubleshooting. If you want to make them ahead for a party or adjust for dietary needs, read the sections below before you start.
Ingredient Notes
A quick orientation before you measure: this recipe relies on room-temperature dairy for proper creaming and on a single dough that holds its shape. Read these notes to avoid common texture problems and to make the bake as smooth as possible.
Ingredients
- 1 cup unsalted butter — creaming fat; room temperature for proper aeration. If you use salted butter, omit the 1/2 teaspoon salt in the recipe.
- 1 cup granulated sugar — provides structure and sweetness; creamed with butter for lift.
- 2 large eggs — binders that add moisture and help structure; use large eggs at room temperature if possible.
- 1/2 teaspoon salt — balances sweetness and strengthens flavor; omit when using salted butter.
- 1 teaspoon vanilla extract — base vanilla note to complement cake-batter flavoring.
- 1 1/2 teaspoons cake batter flavoring — concentrated flavor that creates the “birthday cake” profile; essential for the intended taste.
- 2 teaspoons baking powder — leavening to give modest rise while keeping cookies tender.
- 3 cups all-purpose flour — the bulk of the structure; measure by spooning into the cup and leveling or weigh for consistency.
- 1/4 cup rainbow sprinkles — folded into the dough for color bursts; reserve about 1 tablespoon for topping per the instructions.
- 4 ounces cream cheese — softened for the frosting; provides tang and stabilizes sweetness.
- 3 tablespoons butter — softened and mixed into the frosting for richness and pipeability.
- 2 cups powdered sugar — sweetens and thickens the frosting; sift if lumpy for a smooth finish.
- 3 tablespoons milk — adjusts frosting consistency; add slowly if you need to thin the frosting.
- 1/2 teaspoon cake batter flavoring — folded into the frosting to echo the cookie’s flavor.
Cook Birthday Cake Cookies Like This
- Preheat the oven to 350°F (177°C). Line two baking sheets with parchment paper.
- Measure 1/4 cup rainbow sprinkles. Reserve about 1 tablespoon for topping and set it aside; add the remaining sprinkles to the dough in a later step.
- If you use salted butter, omit the 1/2 teaspoon salt from the recipe.
- In a large bowl, place 1 cup unsalted butter (room temperature) and 1 cup granulated sugar. Using an electric mixer, cream together on medium speed until light and fluffy, about 2–3 minutes.
- Add 2 large eggs and mix on medium speed until fully incorporated.
- Add 1/2 teaspoon salt (unless you used salted butter), 1 teaspoon vanilla extract, and 1 1/2 teaspoons cake batter flavoring. Mix briefly to combine.
- Add 2 teaspoons baking powder and 3 cups all-purpose flour. Mix on low speed just until the flour is incorporated and a dough forms. Do not overmix.
- Fold the measured portion of rainbow sprinkles (the portion not reserved for topping) into the dough by hand until evenly distributed.
- Portion the dough into 12 equal balls using a 1/4-cup measuring cup (or about 75 grams per ball). Place six dough balls on each prepared baking sheet, spacing them about 2 inches apart.
- Press each dough ball gently with a flat-bottomed glass to spread them to just under 1/4 inch thickness.
- Bake at 350°F for 11–12 minutes for a slightly underbaked center. Add 1–2 minutes if you prefer firmer, more well-done cookies. Remove from oven and let cookies cool on the baking sheet for 2 minutes.
- Transfer the cookies to a wire cooling rack and cool completely before frosting.
- Make the frosting: in a medium mixing bowl, beat 4 ounces softened cream cheese and 3 tablespoons softened butter until smooth. Add 2 cups powdered sugar, 3 tablespoons milk, and 1/2 teaspoon cake batter flavoring. Beat until the frosting is smooth and spreadable.
- Fit a piping bag with a medium tip, fill it with frosting, and pipe a pinwheel on each cooled cookie, starting from the center and working outward. Immediately top each frosted cookie with the reserved sprinkles.
- Allow the frosted cookies to sit for about 30 minutes to let the frosting firm before serving.
Why It’s Crowd-Pleasing
There’s a simple chemistry to crowd-pleasers: familiar flavor, visual appeal, and a texture that satisfies. These cookies check all three boxes. The cake-batter flavoring gives a childhood-cake aroma that almost everyone recognizes. Rainbow sprinkles add color and a playful crunch. The cream-cheese frosting keeps sweetness balanced with a hint of tang, which prevents the cookie from tasting cloying even after a couple of bites.
They’re also portioned predictably—12 cookies per batch—so they behave well on a dessert table. The pinwheel frosting makes them look professionally finished without elaborate decorating skills.
Easy Ingredient Swaps
- Unsalted butter — if you only have salted butter, use it and skip the 1/2 teaspoon salt in the dough; the final taste will be similar.
- All-purpose flour — for slightly more tender cookies, you can try a blend of 2 3/4 cups AP flour + 1/4 cup cake flour, but weigh ingredients for accuracy.
- Cake batter flavoring — vanilla bean paste can boost vanilla notes, but it won’t replace the concentrated “batter” profile; expect a milder cake flavor.
- Milk in frosting — use any dairy milk or unsweetened plant milk; add by teaspoon if you need to thin the frosting gently.
- Sprinkles — use standard rainbow jimmies rather than nonpareils to avoid color bleed; avoid metallic or gelatin-based sprinkles if serving to vegetarians who avoid gelatin.
Equipment at a Glance
- Electric mixer (hand or stand) — for creaming butter and sugar and smoothing the frosting.
- Measuring cups and spoons — accurate measuring keeps texture consistent.
- 1/4-cup measuring cup or kitchen scale — for portioning 12 even cookies.
- Baking sheets and parchment paper — prevents sticking and promotes even browning.
- Flat-bottomed glass — to press dough balls to the right thickness.
- Wire cooling rack — lets cookies cool completely before frosting.
- Piping bag and medium piping tip — for the pinwheel frosting; a small offset spatula works if you prefer to spread.
Learn from These Mistakes
Overcreaming or undercreaming
Overcreaming butter and sugar incorporates too much air and can cause cookies to spread unevenly. Undercreaming won’t give you the lightness needed for the tender texture. Aim for 2–3 minutes on medium speed until the mixture is noticeably lighter in color and texture.
Adding flour on high speed
Mixing flour at high speed develops gluten and yields tougher cookies. Mix on low just until combined; then stop. The dough should come together without becoming dense.
Baking time mistakes
These are meant to be slightly underbaked for a soft center. If you want firmer cookies, add the extra 1–2 minutes the recipe mentions. Remove them from the oven when edges look set but centers still look slightly soft.
Frosting on warm cookies
Frosting a warm cookie will melt the frosting and ruin the piping. Always cool completely on a wire rack before decorating.
Spring to Winter: Ideas
Seasonal styling keeps this cookie fresh year-round. In spring, pair the frosting with pastel sprinkles and add a tiny edible flower for a brunch or baby shower. Summer parties benefit from brighter sprinkles and a slightly thicker frosting so it survives outdoor heat—chill the frosting briefly before piping.
In fall or winter, swap the rainbow sprinkles for complementary colors (muted gold, copper, or deep red). For colder months, serve cookies at room temperature so the cream-cheese frosting stays creamy rather than cold and firm.
Flavor Logic
The core flavors are vanilla, cake-batter concentrate, and a touch of cream-cheese tang. Cake-batter flavoring provides concentrated notes that mimic vanilla, butter, and a slight egginess—this is what makes the cookie distinctly “birthday cake.” The additional vanilla extract lifts the background flavor and keeps the profile rounded.
Powdered sugar in the frosting contributes smooth sweetness and structure. Cream cheese cuts through the sugar with mild acidity, keeping the mouthfeel balanced and preventing the frosting from tasting one-note sweet.
Shelf Life & Storage
Unfrosted cookies: store in an airtight container at room temperature for up to 4 days. For longer storage, freeze unbaked dough balls or baked unfrosted cookies for up to 3 months; thaw at room temperature before frosting.
Frosted cookies: because the frosting contains cream cheese, keep them refrigerated in a single layer or with parchment between layers. They keep well for up to 3 days in the fridge. Let them sit at room temperature 20–30 minutes before serving to soften the frosting.
Transporting: for short trips, place cookies in a shallow box with parchment and keep them flat. For longer transport, refrigerate until firm and then pack with minimal movement to protect the piped pinwheels.
Quick Questions
- Can I freeze the dough? — Yes. Portion into 1/4-cup balls, freeze solid on a tray, then transfer to a sealed bag for up to 3 months. Bake from frozen, adding 1–2 minutes to the bake time.
- Can I skip the cream cheese in the frosting? — You can substitute additional butter for a pure buttercream, but flavor and tang will change. If using butter-only frosting, chill briefly before piping for cleaner lines.
- Why do my sprinkles bleed color? — Some sprinkles release dye when mixed into wet dough or melted frostings. Use jimmies (long sprinkles) or sprinkle on top immediately after piping to minimize bleeding.
- How do I make the frosting stiffer? — Add more powdered sugar in 1/4 cup increments and beat until you reach pipeable stiffness. Chill briefly if needed.
Final Bite
These Birthday Cake Cookies are straightforward to make and deliver the celebratory look and flavor people expect. Follow the exact steps for best texture, keep the frosting cool until you’re ready to pipe, and reserve sprinkles for the final touch. They’re forgiving, photogenic, and easy to scale—and they always draw a smile at the dessert table.
When you bake them, take notes on timing and oven behavior so your next batch is even easier. Happy baking—and enjoy the party on a plate.
