These soft, buttery cookies are bursting with cake batter flavor and topped with creamy, sweet frosting—just like a slice of birthday cake in every bite!
Cake Batter Cookie Base
1 1/2 cups (333g) salted butter, softened
1 1/2 cups (345g) granulated sugar
3 eggs
1 1/2 teaspoons cake batter flavoring
4 1/2 cups (684g) all-purpose flour
3 teaspoons baking powder
1/4 cup (54g) sprinkles (optional)
Cake Batter Cream Cheese Frosting
8 oz cream cheese, room temperature
1/4 cup (56g) salted butter, softened
1/2 teaspoon cake batter flavoring
4 cups (428g) powdered sugar
Milk, to thin as needed
Extra sprinkles, for garnish
Make the Cookies:
Preheat oven to 350°F (175°C).
Cream together softened butter and sugar until light and fluffy (about 2–3 minutes).
Scrape sides, then add eggs and cake batter flavoring. Beat until well combined.
Add flour and baking powder. Mix until fully incorporated. Fold in sprinkles, if using.
Scoop out 1/3 cup portions (about 3.25 oz) of dough, roll into balls, and flatten into hockey puck shapes.
Place 6 cookies per baking sheet.
Bake for 12–15 minutes, or until cookies puff up and centers are no longer glossy.
Allow cookies to cool on pan for 10–15 minutes before frosting.
Make the Frosting:
Beat cream cheese and butter together until smooth and creamy.
Add powdered sugar one cup at a time, mixing thoroughly after each addition.
Stir in cake batter flavoring. Add milk 1 teaspoon at a time if frosting is too thick.
Transfer frosting to a zip-top bag, snip a corner, and pipe in a spiral onto slightly warm cookies.
Top with additional sprinkles and serve warm!
Don’t overbake! Cookies should look slightly underdone when removed from the oven—they will set as they cool.
Cake batter flavoring is key to achieving the signature “birthday cake” flavor—don’t skip it.
For smaller cookies, use a smaller scoop and reduce baking time to 9–11 minutes.
