Blueberry cupcake batter. Inspired by NotCharlesManson's Batter Up. By inspired, I mean I used RF Blueberry instead. Give it at least a week to age and let the blueberry really come out. Or vape it right away, idgaf. It just won't be as good.
Blueberry muffin batter. Age at least 3 days. If you want it a little more complex, try adding either .2% FA Walnut, 1% CAP Vanilla Custard v1, or .25% FA Torrone.
