Sift each cake mix into a large bowl. There will be small bits of dried strawberries in the Strawberry supreme cake mix — these can be discarded.
Measure each mix into precise ¼ cup portions by spooning the mix into a ¼ cup measuring cup, and then leveling it off with a knife. Place each portion in a Ziploc snack bag and label. You should end up with at least 11 refills per box of cake mix, but more than this is possible with the recent updates to the mixes.
To bake each refill mix:
Heat your Easy Bake Oven for 20 minutes. Lightly spray the Easy Bake cake pan with baking spray. Check out this easy no mess baking spray tip!
When the oven is done heating, mix the contents of one refill bag with 2 tablespoons of water. Spread the batter evenly in the prepared pan.
Bake the cake in the Easy Bake Ultimate Oven for approximately 17 minutes.
Cool for 5 minutes before removing the cake from the pan. Frost and decorate with sprinkles, as desired.
