You will need:
- One box of white cake mix, OR the yellow mix that TASTES LIKE THE WHITE, not a butter cake mix
- 5 TB melted butter
- 2 beaten eggs
- A jar of sprinkles. One of those 2.5-3oz ones
Mix together the first 3 ingredients. Mix in about 3/4ths of the sprinkles. Wow, so tiring. ;)
Spread the mix into a 9x13 pan, sprinkle on those remaining sprinkles. Bake at 350 for about 15-20 minutes. Cool in the baking pan, then cut into preferred-size bars.
My five-year-old loves these, and can pretty much make them by herself! (Except for the hot oven part of course!)
