Protein cookies get their protein from low-fat quark, skyr, almond flour and a little whey protein: every recipe here has at least 20 g protein per serving and at least 20 % of its calories from protein. They’re sweetened with honey, maple syrup or coconut sugar – that’s still sugar, so enjoy the cookies in moderation.
Part of the flour and butter is replaced with low-fat quark, skyr, almond flour or whey protein. Only recipes with at least 20 g protein per serving and at least 20 % of their calories from protein make it in here – you’ll find the figure on every recipe.
An unflavoured or vanilla whey protein without sweeteners – otherwise the dough tastes artificial. It soaks up a lot of liquid: add it a tablespoon at a time until the dough holds its shape.
Quark keeps the dough moist, but it dries out faster in the oven. Bake the cookies a little shorter and keep them in an airtight tin.
