Preheat the Oven

Preheat your oven to 350°F (175°C).

Line two baking sheets with parchment paper or silicone baking mats.

Mix the Wet Ingredients

In a large bowl, use an electric mixer to beat the cream cheese, butter, egg, and vanilla extract until smooth and creamy.

Add the Cake Mix

Gradually stir in the cake mix until a thick dough forms.

Fold in Sprinkles

Gently fold in the holiday sprinkles, careful not to overmix to prevent the colours from bleeding into the dough.

Chill the Dough

Chill the dough in the refrigerator for at least 30 minutes to make it easier to handle.

Shape and Coat

Scoop out 1½-inch balls of dough using a cookie scoop or spoon.

Roll each ball in powdered sugar until fully coated.

Bake

Place the dough balls on the prepared baking sheets, spacing them about 2 inches apart.

Bake for 10–12 minutes until the edges are set but the centres remain slightly soft.

Cool

Let the cookies cool on the baking sheets for a few minutes before transferring them to a wire rack to cool completely.
