1-First Step: Prep your workspace Preheat oven to 350°F and line two baking sheets with parchment paper. Soften ½ cup butter at room temperature for 30 minutes. This mise en place keeps your funfetti milkshake cookies recipe moving fast. For vegan adaptations, prepare flax egg ahead and measure almond milk.

2-Second Step: Cream the wet ingredients Beat softened butter with ¾ cup sugar until light and fluffy, about 2 minutes. Add 1 egg, 1 tsp vanilla, and ¼ cup milk, mixing until smooth. Use room-temp items for even texture in these creamy milkshake cookies. If low-calorie, use light butter here.

3-Third Step: Combine dry ingredients In a separate bowl, whisk 1½ cups funfetti cake mix, ½ cup vanilla pudding mix, 1 tsp baking soda, and ½ tsp salt. Gradually stir dry into wet mixture until just combined. Avoid overmixing to keep thick funfetti cookies tender. Gluten-free mix works perfectly with no changes.

4-Fourth Step: Fold in sprinkles Gently fold in ½ cup Christmas sprinkles. The dough should be scoopable, not sticky. Chill balls for 30 minutes on the sheet for better shape. This step prevents color bleeding and enhances chewiness in Christmas cookies.

5-Fifth Step: Scoop and bake Scoop tablespoon-sized dough balls, spacing 2 inches apart. Bake 10-12 minutes until edges are golden. Centers stay soft for that milkshake vibe. Cool on sheet 5 minutes, then transfer to rack. For frozen dough, add 1-2 minutes.

6-Sixth Step: Finishing touches Once cool, store or serve. Add extra sprinkles on top for presentation. Pair with milk to amplify the funfetti milkshake cookies recipe experience. Customize with white chocolate chips in the dough for variety.
