Nonpareils (or “sprinkles”) are available in baking supply stores in various shapes and sizes. Note that there are “sprinkles” that are too large and thick to be mixed into the batter. The large ones are good for decorating but, mixed into the batter, they will not soften sufficiently during baking. So, choose small ones. Small and thin.
Most confetti cupcake or confetti cake recipes use only egg whites to achieve an almost white color that best sets off the bright hues of the sprinkles. I used a whole egg instead as I didn’t want to bother thinking what I would do with the egg yolks.

- Add another third of the flour, then the remaining half of the buttermilk and, finally, the last third of the flour, mixing after each addition.
- If using vanilla extract, stir it in.
- Mix together the baking soda and vinegar (it will fizzle).
- Add to the cake batter and mix in.
- Add the sprinkles to the batter and stir in.
