For anyone woondering, 300g banana I interpreted as without peel and it turns out to about 2 and a half bananas.
Pretty good recipe. I'd add a bit more truvia next time though.
I put some blueberries in half of them (I made 10 as I didn't have big muffin cases) and I liked that a lot once cooled. The ones without blueberries also tastes nice, though next time I make them I'd add some banana slices, to really bring out the banana flavour.
