I am Homer Simpson when faced with a sprinkled donut. Funfetti was my childhood favorite boxed cake and tubed frosting. And, I always choose rainbow sprinkles at our favorite froyo bar, Yogurtology.
- 16 tablespoons (225 grams, 2 sticks) butter, at room temperature
- 1 1/2 cups (300 grams) sugar
- 2 tablespoons (50 grams) glucose or 1 tablespoon (25 grams) corn syrup
- 2 eggs
- 2 teaspoons (8 grams) clear vanilla extract
- 2 1/2 cups (400 grams) flour
- 2/3 cup (50 grams) milk powder
- 2 teaspoons (9 grams) cream of tartar
- 1 teaspoon (6 grams) baking soda
- 1 1/4 teaspoons (5 grams) kosher salt
- 1/4 cup (40 grams) rainbow sprinkles
- 1/2 recipe Birthday Cake Crumbs
For “Birthday Cake Crumb”
- 1/2 cup (100 grams) granulated sugar
- 1 1/2 tablespoons (25 grams) light brown sugar, lightly packed
- 3/4 cup (90 grams) cake flour
- 1/2 teaspoon (2 grams) baking powder
- 1/2 teaspoon (2 grams) kosher salt
- 2 tablespoons (20 grams) rainbow sprinkles
- 1/4 cup (40 grams) grapeseed oil
- 1 tablespoon (12 grams) clear vanilla extract
For the Birthday Cake Crumb: Heat the oven to 300°F.
Combine the sugars, flour, baking powder, salt, and sprinkles in the bowl of a stand mixer fitted with the paddle attachment and mix on low speed until well combined.
Add the oil and vanilla and paddle again to distribute. The wet ingredients will act as glue to help the dry ingredients form small clusters; continue paddling until that happens.
Spread the clusters on a parchment- or Silpat-lined sheet pan. Bake for 20 minutes, breaking them up occasionally. The crumbs should still be slightly moist to the touch; they will dry and harden as they cool.
For the Confetti Cookies:
- Combine the butter, sugar and glucose in the bowl of an electric mixer fitted with a paddle attachment and cream together on medium-high for 2-3 minutes
- Scrape down the sides, add in the eggs and vanilla and beat for 7-8 minutes (this is VERY important, don’t skimp on the time!)
- Reduce mixer speed to low and add in the flour, milk powder, cream of tartar, baking soda, salt and sprinkles. Mix just until the dough comes together – no longer than 1 minute. Scrape down the sides of the bowl.
- With the mixer on low, add int he birthday cake crumbs and mix in for 30 seconds – until they’re just incorporated
- Using a 2 3/4 oz. ice cream scoop (1/3 cup measure) portion out the dough onto a parchment paper lined baking sheet – you should get 15-20 large balls of dough.
- Pat the tops of the cookie balls flat – wrap the sheet pan tightly in plastic wrap and chill for at least 1 hour or up to 1 week. Do not bake the cookies from room temp – they will not bake properly!
- Heat the oven to 350°F
- Arrange the chilled dough at least 4 inches apart on the baking sheet (I fit 6 on each sheet) and bake for 18 minutes – the cookies will puff, crackle and spread. The cookies should look lightly browned on the edges (golden brown on the bottom) – the centers will show just the beginning signs of color. If they haven’t reached that color yet, leave them in a for an extra minute or two .
- Cool the cookies completely on the sheet pans before transferring to a plate or airtight container for storage.
