I started using this recipe

But then went a little rogue. Here's what I actually used in the recipe
80g organic oats
80g 1:1 gluten free flour
3 scoops (100g) vegan protein powder (I used Hy-Vee vanilla pea protein powder)
1/4 cup honey
2 tsp. baking powder
1/2 tsp. salt
4 medium over-ripe bananas
3 Tbsp ground flaxseed
2 large egg
1/2 tsp cinnamon
2 tbsp. Olive oil or coconut oil, melted
I baked the 12 muffins in the 350 deg F oven for about 25 minutes.
They turned out ok, but I will have to refine the recipe. They are not super sweet but at the same time, sweet enough to be tolerable. I can definitely taste the protein powder, so not sure about that either. Texture-wise, I think they are pretty good, not gummy, but not super light/delicate.
