1. Get Ready to Bake: Preheat your oven to 350°F (175°C). Line two baking sheets with parchment paper – this makes cleanup a breeze!
2. Mix the Wet Stuff: In a large bowl, use an electric mixer to beat the softened cream cheese, butter, egg, and vanilla extract until everything is wonderfully smooth and creamy.
3. Add the Cake Mix: Slowly mix in the yellow cake mix. Keep stirring until a thick, slightly sticky dough forms. Don't worry, sticky is good for gooey cookies!
4. Fold in the Fun: Gently fold in your holiday sprinkles. Be careful not to overmix, so the colors stay vibrant and don't bleed into the dough.
5. Chill Out: Pop the dough in the fridge to chill for at least 30 minutes. This makes it much easier to handle and roll.
6. Roll 'Em Up: Scoop out about 1.5-inch balls of dough. Roll each ball generously in powdered sugar until it's completely coated.
7. Bake to Perfection: Place the coated dough balls on your prepared baking sheets, leaving about 2 inches between them. Bake for 10-12 minutes. The edges should look set, but the centers should still be deliciously soft. This is key for that gooey texture!
8. Cool Down: Let the cookies cool on the baking sheets for a few minutes before moving them to a wire rack to finish cooling completely. Enjoy your festive, gooey treats!
