Preheat the oven to 350 degrees.

In the bowl of a stand mixer (you can also do it with a hand mixer), mix together the cake mix, 2 egg whites and a stick of butter.

Mix it until it comes together, and it will be thick but sticky.

Spoon it out on a large piece of plastic wrap and wrap it up tight, then pop it into the fridge for an hour or two (or even overnight.)

Once the dough is firm, cut it into 12-14 pieces.

Use the flour to coat your hands, then roll each piece into a ball. Press out the ball into a flat disc while pressing it into the sprinkles or the sugar.

Make sure each piece is coated well, then put onto a non-stick cookie sheet.

Place the candy eyes on top before baking. Give them plenty of room (about 5-6 to a sheet pan) because they will spread quite a lot while cooking.

Bake for 10-12 minutes, or until the bottoms are golden brown.

Place on a cooling rack to allow them to cool before serving.
