Blueberry Mug Cake (plant-based + gluten-free)

I love mug cakes because they’re single-serve aka perfect for when you want something simple and quick.

This Blueberry Mug Cake is vegan, gluten-free, and made with oat flour.

I love making my own oat flour at home (you literally just put oats into a blender or food processor… see my tutorial in my Instagram highlights). It’s the cheapest gluten-free flour on the market and I love that it’s only one ingredient– oats!

This recipe also calls for a flax egg, a great alternative to a real egg for vegans or anyone with an egg allergy, and also a good source of fiber. I have flax egg tutorial (all you need is ground flax and water) in my Instagram highlights as well 😊
