1-First Step: Begin by preheating your oven to 350°F (175°C). This temperature is ideal for achieving perfectly baked Christmas Funfetti Milkshake Cookies with golden edges and soft centers. While the oven heats, line two baking sheets with parchment paper to prevent sticking and ensure easy cleanup. Prepare your ingredients by bringing the butter and eggs to room temperature, which helps them incorporate more smoothly into the dough. Measure out all ingredients beforehand to make the mixing process seamless and efficient.

2-Second Step: In a large mixing bowl, combine the vanilla cake mix, vanilla instant pudding mix, softened butter, eggs, and vanilla extract. Using an electric mixer or sturdy spoon, beat these ingredients together until a thick dough forms. This typically takes about 2-3 minutes on medium speed. The mixture might seem stiff at first, but continue mixing until all ingredients are fully incorporated. The pudding mix will absorb some of the moisture, creating that signature milkshake-thick texture that makes these funfetti cookies so special.

3-Third Step: Once your dough is well-combined, gently fold in ⅓ cup of the red and green Christmas sprinkles using a spatula or wooden spoon. Be careful not to overmix at this stage, as you want to distribute the sprinkles evenly without crushing them or toughening the dough. The remaining sprinkles will be used later to coat the outside of the dough balls, creating that festive, colorful appearance that makes these holiday cookies so visually appealing.

4-Fourth Step: Scoop approximately 1.5 tablespoons of dough and roll it into a ball between your palms. If the dough feels too sticky to handle, refrigerate it for 15 minutes to firm up slightly. Roll each dough ball in the remaining Christmas sprinkles, pressing gently to ensure they adhere well. Place the coated balls on your prepared baking sheets, spacing them about 2 inches apart to allow for spreading. This spacing is crucial for achieving perfectly shaped sprinkle cookies rather than one giant connected cookie.

5-Fifth Step: Bake the cookie sheets in your preheated oven for 10-12 minutes. Watch closely during the last few minutes of baking, as oven temperatures can vary. You’ll know they’re done when the edges are lightly golden but the centers still appear slightly soft. This slight underbaking ensures your soft funfetti cookies recipe produces treats with that perfect chewy texture reminiscent of a thick milkshake.

6-Sixth Step: Remove the cookies from the oven and let them cool on the baking sheets for 5 minutes. This resting period allows them to set slightly so they don’t break when you move them. After 5 minutes, carefully transfer the cookies to a wire rack to cool completely. This step is essential before adding the milkshake frosting, as warm cookies would cause the frosting to melt and lose its shape.

7-Seventh Step: While the cookies cool, prepare the signature milkshake frosting. In a medium bowl, beat the softened butter until smooth and creamy. Gradually add the powdered sugar, mixing well after each addition to prevent lumps. Pour in the milk and vanilla extract, then continue beating until the frosting becomes light, fluffy, and spreadable. The consistency should be similar to that of a thick milkshake, complementing the cookie’s texture perfectly.

8-Eighth Step: Once the cookies are completely cool, frost them either by spreading the milkshake frosting with a knife or piping it on for a more decorative finish. For a professional look, use a piping bag fitted with a star tip to create beautiful swirls of frosting on each cookie. Top with additional sprinkles if desired for extra festive flair. These Christmas Funfetti Milkshake Cookies are now ready to serve and will bring holiday cheer to any gathering!
