Tips for baking with Formula 1
Formula 1 doesn’t provide structure the way flour does, so keep the egg or banana in the mix, that’s what binds everything together.
For an extra protein hit without changing the flavour, add a scoop of unflavoured Protein Drink Mix (PDM).
Bakes made with Formula 1 come out a little denser than standard ones, that’s normal, and the trade-off is more protein and less sugar per serving.
