Instructions

Make the Filling

1. In a medium bowl, mix cream cheese, powdered sugar, birthday cake extract, and almond extract until smooth.

2. Fold in marshmallows, sprinkles, and sanding sugar (if using).

3. Scoop 10 portions (about 1 tablespoon each) onto a parchment-lined plate.

4. Freeze for at least 90-120 minutes until firm.

   Make the Dough

5. Preheat oven to 350°F (175°C).

6. Line two baking sheets with parchment paper.

7. Cream butter and sugar for 2–3 minutes until light and fluffy.

8. Beat in egg, birthday cake extract, and almond extract.

9. In a separate bowl, whisk together flour, baking powder, baking soda, and salt.

10. Add dry ingredients to wet ingredients and mix just until combined.

    Assemble

11. Divide dough into 10 equal portions (about 95–100g each for bakery-size cookies).

12. Flatten each portion into a thick disc.

13. Place one frozen filling ball in the center.

14. Wrap dough completely around filling and seal well.

15. Roll each cookie generously in rainbow sprinkles.

16. Place on baking sheet and chill 15–20 minutes.

    Bake

17. Bake for 12–14 minutes until edges are lightly set and centers still appear slightly underbaked.

18. Let cool on the baking sheet for 10 minutes.

19. Transfer to a wire rack.

    Baker’s Notes

The filling should be frozen solid before stuffing.

Pull the cookies when the centers still look slightly soft for the gooey middle.

If your oven runs hot, start checking at 11 minutes.

Jimmies work better than nonpareils because they don’t bleed as much during baking.

A small pinch of almond extract is what gives many bakery birthday-cake desserts their signature flavor.

This gives a Crumbl-style birthday cake cookie with lots of texture and visual appeal.

For your pantry, I’d make the original recipe with the sanding sugar in the filling. That little bit of crunch against the gooey cream cheese-marshmallow center sounds closest to the cookie you’re remembering. 🎂🍪✨
