Crumbl Birthday Cake Cookies

Step 1

Preheat the oven to 350°F.

Step 2

In a large bowl combine butter and granulated sugar. Cream butter and sugar together with an electric mixture unil the butter is light and fluffy.

Step 3

After the butter and sugar are light and fluffy, add 2 large eggs and mix well.

Step 4

Add salt, vanilla extract, cake batter flavoring, baking powder, and flour to the butter mixture. Mix until the flour is well incorporated.

Step 5

Add 1/4 cup rainbow sprinkles, and mix into batter.

Step 6

Portion the cookie dough into 12 dough balls with either a 1/4 cup measuring cup. You can use a scale to portion the dough by 75 grams. You will have a very small portion left over.

Step 7

Place the dough balls onto two parchment-lined baking sheets. Place six dough balls on each sheet. Press each dough ball gently with a glass to spread them out to just under 1/4 inch thickness.

Step 8

Bake cookies for 11 to 12 minutes, for a slightly underbaked texture. Add a minute or two if you want them more well done.

Step 9

Allow the cookies to cool on the baking sheet for 2 minutes before transferring them to a cooling rack to cool completely before applying frosting.

Step 10

Combine all the frosting ingredients in a medium mixing bowl and blend until smooth using an electric mixer.

Step 11

Place the frosting in a piping bag with a medium tip. Pipe the frosting onto cookies in a pinwheel pattern, starting from the center and working outward, and immediately top with sprinkles.

Step 12

Allow the frosting to sit for 30 minutes to stiffen before serving.
