this recipe is loosely based on one from http://www.theppk.com/ but I changed it a lot, so am posting it here. They are really tasty.
you will need:
115g plain flour
1 tbsp baking powder
1 tsp flaky sea salt
1 mashed banana
2 tbsp crunchy peanut butter
100ml rapeseed oil
120ml soy milk (plus extra if needed)
squeeze of lemon juice
50g dairy-free dark chocolate, smashed into bits
Pre-heat oven to 200 degrees
Combine the flour, cornmeal, sugar, baking powder in one bowl, make sure there are no lumps.
In another bowl whisk together the banana, peanut butter, oil, lemon juice and soy milk. Add this to the dry ingredients. If your mixture looks too thick then add some more soy milk to make it runnier, you want a thick batter texture.
Fold in the chocolate bits.
Pour into greased muffin tins, fill them 3/4 of the way to the top.
Bake for 18 minutes.
