Cook the cakes and add fillings. Pour the batter from step 2 about 70% full into each hole using a spoon. Place fillings at the center of each hole, and cover with a small amount of batter.
For red, orange, yellow and blue, place half teaspoon of matching jam.
For green, place 5 white chocolate chips.
For purple, place 5 raisins.
Tip: Try making in smaller batches first to prevent them from burning. We recommend practicing with one hole before making the rest.
