FAQ
How much protein is in each bar?
It depends on your protein powder and bar size. With a standard vegan protein (about 20–25 g per scoop) and 10–12 bars per batch, you’ll usually get 8–12 g protein per bar.
Can I make them without protein powder?
Yes, replace the protein powder with fine oat flour and add a pinch of salt and vanilla. The bars will have less protein but still taste great.
My dough is too dry.
What should I do?
Add 1 tablespoon plant milk at a time and mix until the dough presses together easily.
Can I bake these bars?
They’re designed as no-bake bars. Baking can make them dry and crumbly, so it’s best to chill instead.
Which nut or seed butter works best?
Use a drippy, well-stirred jar. Peanut butter adds bold flavor; almond or cashew butter tastes milder; sunflower seed butter keeps them nut-free.
