Snap, I thought I invented that recipe!
Apart from that I use self-raising flour and have no idea how many cups of each…just so that the consistancy is right…
I just use Whole Foods protein pancake and waffle mix.
Side note: A lot of those MTB pros are young. They also eat pizza and wings and drink Red Bull and beer and stay skinny. I miss being young.
I made a completely random pancake recipe myself a few days ago - it worked out amazingly (fluke).
2 eggs
1.5 bananas
1 scoop instant oats (MyProtein)
1 scoop chocolate smooth whey brotein (MyProtein)
1 pinch baking powder
Came out fluffy and awesome!
