In an electric mixer, beat together the butter, yogurt, syrup and honey, and flour until smooth. (The batter should be light and fluffy, but thick enough to sit on a spoon. If it's too runny, feel free to add another 1/4 cup of flour to the batter. Sometimes the thickness of the batter will change when using brown rice syrup or honey as a sweetener).

Fold in the rainbow sprinkles. If you want to add more that just a half cup, feel free. The more, the festiver.

Spoon batter into muffin tins lined with cupcake wrappers. Bake in an oven preheated to 350 degrees for 17-19 minutes.

Feed to your birthday teenager and enjoy!
