Cookie Recipe
- 2 1/4 cup (214g) all purpose flour, sifted
- 1/2 tsp baking powder
- 1/2 tsp salt
- 3/4 cup (170g) unsalted butter, softened
- 1/2 cup (100g) granulated sugar
- 1/2 cup (60g) powdered sugar
- 2 large eggs, room temperature
- 2 tsp vanilla extract
- 1/4 tsp almond extract, optional
- 1/4 tsp butter extract
- 4 tbsp rainbow sprinkles
Cookie Frosting Recipe
- 6 tbsp (85g) unsalted butter, softened
- 2 cups (240g) powdered sugar
- 1 tsp vanilla extract
- 1 tbsp heavy cream
- 1 tsp lemon juice, real, not the extract or concentrate it is a game changer!
- pinch of salt
- rainbow sprinkles, topping
Directions:
1
Prepare a large cookie sheet with parchment paper, set aside. Set the oven to 350 degrees.
In small bowl add in the flour, baking powder, and salt. Give it a mix and set it aside.
2
To a standing mixer fitted with the paddle attachment, add the butter, granulated sugar, and powdered sugar and beat for 6 minutes on medium/high. Scrape the bowl and add the 2 eggs one at a time, scraping in between each addition. Add the extracts.
3
Add in the flour mixture and the sprinkles to the batter and mix on low until just incorporated. Use a large cookie scooper to scoop large perfect balls of dough on a cookie sheet. Do not overcrowd the sheet! I only put 4 balls on each cookie sheet.
4
Bake the cookies at 350 degrees for 14 minutes only! The cookies will feel soft but they will finish cooking with carry over heat. As the cookies cool, in a standing mixer fitted with a paddle attachment, beat the butter and powdered sugar together.
5
Add the heavy cream, vanilla, lemon juice, and salt. Beat until the frosting is smooth and pipeable. Once the cookies are cooled, frost the cookies using a butterknife. OR fill a piping bag and pipe the frosting on the cookie in any design you’d like! Top with rainbow sprinkles and enjoy!
Optional: Feel free to add food coloring to your frosting! I chose a baby pink! I love the added color with the rainbow sprinkles on top!
