Commercial protein bars cost 3-4€ a pop and list 26 ingredients, most of which you can't pronounce. Homemade quark bars solve both problems at the same time — 50-70% cheaper per bar, 5-10 ingredients you recognize, and the protein number actually lives up to the label.
These recipes use quark as the base because nothing else gets you to 25g+ protein per bar without tasting like a chalk brick. No-bake options dominate the list (most hit the fridge within 15 minutes), with a few baked recipes for when you want that crispy edge. Every one has a full macro breakdown so you can slot it into your day without guessing.
A quark bar is a snack bar made with quark, a fresh, mild dairy cheese that is naturally high in protein. The quark is mixed with oats, protein powder or nut butter, pressed into a tin and chilled until firm, which gives a soft, cheesecake-like bar with far more protein than a granola bar.
The name covers two things. In Estonia, Latvia, Lithuania and further east, a quark bar is the glazed curd snack sold chilled in the dairy aisle: sweetened quark pressed into a small bar and dipped in chocolate (kohuke in Estonian, biezpiena sieriņš in Latvian, sūrelis in Lithuanian, syrok in Russian). The recipes on this site are the other kind: homemade protein bars, with more protein and less sugar.
Quark works because lean quark has about 11 g of protein per 100 g, most of it casein, which digests slowly and keeps you full. It tastes mild and slightly tangy, so it takes chocolate, coffee, fruit or spice equally well, and per gram of protein it costs a fraction of a store-bought protein bar.
The starting point for every flavour below. No oven, about 15 minutes of work, then the freezer does the rest.
Per bar: about 25 g protein and 320 kcal if you cut 4, or 16 g protein and 210 kcal if you cut 6.
They are a good high-protein snack: the basic recipe gives 16–25 g of protein per bar with oats and nut butter rather than syrups and fillers. They are still a snack with 200–320 kcal each, so treat them as one.
Up to 4 days in an airtight box in the fridge, or about 2 months in the freezer. Take one out 10 minutes before eating if it is frozen.
Yes. Replace the powder with more oats and nut butter. They hold together just as well but have less protein, about 10 g per bar instead of 16.
The quark was too wet or they were cut too warm. Use the thickest quark you can find, or drain it in a sieve for 30 minutes, and cut the bars while they are still firm from the freezer.
