Add the cake mix, eggs, oil, and extract to a large mixing bowl. Using a hand mixer, blend everything together until evenly combined. The batter will be stiff, but that's ok.
1 15.25 oz box white cake mix, 2 eggs, 1/4 cup canola oil, 1 tsp vanilla extract
Add the m&m's to the bowl and fold them in with a spatula until evenly incorporated.
1/3 cup red and green m&m's
Pour the sprinkles out into a small bowl.
Christmas colored nonpareil sprinkles
Using a small cookie scoop scoop out balls of dough, then roll in the sprinkles, and transfer to a nonstick baking sheet. Arrange in rows, leaving room for the cookies to spread while baking.
Bake at 350° for 8-10 minutes.
Carefully remove the hot pan from the oven and add a piece of christmas cake to the center of each, gently pressing in just a bit.
