1-First Step: Prep Your Workspace
Preheat oven to 350°F. Line two baking sheets with parchment paper to prevent sticking. This setup ensures even baking for your holiday funfetti cookies recipe. Have all ingredients measured out for quick assembly, ideal for busy schedules.
For dietary tweaks, use parchment safe for vegan or GF bakes. Softened butter should feel like cool room temp, not melted.

2-Second Step: Mix Wet Ingredients
In a large bowl, beat ½ cup softened unsalted butter, 2 large eggs, and 1 tsp vanilla extract. Use a wooden spoon or hand mixer on low for 2 minutes until smooth and creamy. This base captures the milkshake essence in funfetti cookies.
Vegan adaptation: Whisk flax eggs first and let sit 5 minutes to gel. Room-temp eggs prevent lumps.

3-Third Step: Incorporate Dry Mixes
Add 1 box (15 oz) vanilla cake mix and 1 package (3.4 oz) instant vanilla pudding mix to the wet ingredients. Stir vigorously until a thick dough forms, about 1-2 minutes. Scrape sides to blend fully; the pudding mix hydrates for chewy cake mix cookies.
GF note: Stir slowly to avoid toughening. If dough seems dry, add 1 tsp water sparingly.

4-Fourth Step: Fold in Sprinkles
Gently fold in ⅓ cup of the ½ cup red and green Christmas sprinkles. Use a spatula to distribute evenly without crushing colors. Reserve remaining sprinkles for rolling, keeping your Christmas funfetti milkshake cookies vibrant.
Pro tip for low-cal: Use fewer sprinkles inside and more outside.

5-Fifth Step: Portion and Roll Dough
Scoop 1.5 tablespoon portions of dough and roll into balls. Roll each ball in the remaining sprinkles to coat generously. Place 2 inches apart on prepared sheets; they spread during baking.
Chill balls 15 minutes optional for thicker milkshake cookies. Wet hands prevent sticking.

6-Sixth Step: Bake to Perfection
Bake one sheet at a time in the middle rack for 9-11 minutes. Edges set but centers stay soft for chewiness in sprinkle cookies. Rotate halfway if oven uneven.
Overbaking dries them; watch closely past 9 minutes. Altitude adjustment: add 1-2 minutes.

7-Final Step: Cool and Drizzle
Cool cookies on sheets 5 minutes, then transfer to wire racks. Melt ½ cup white chocolate chips in microwave 30-second bursts, stir until smooth. Drizzle over cooled cookies for festive touch.
