Quick Tips

Blend the Cottage Cheese Until Fully Smooth

Take your time blending the cottage cheese with the wet ingredients until there are zero lumps left. If you rush this, you’ll get little chunks of cottage cheese in the finished cookies.

You want it completely creamy, almost like a thin pudding. From my experience, an extra 30 seconds of blending makes a big difference in the final texture.

Don’t Skip the Chill Time

The 25 minute chill is not optional here. This dough is soft and a little sticky, so chilling firms it up and makes it much easier to scoop and shape.

If you bake it warm, the cookies spread out too much and go flat. My favorite trick is to pop the bowl in the fridge while I clean up, so the time passes without me watching the clock.

Measure Your Flours Correctly

Spoon the all-purpose flour and oat flour into your measuring cup, then level it off with a knife. Scooping straight from the bag packs in too much and makes the cookies dry and dense.

The oat flour also soaks up more moisture than regular flour, so getting the amount right really matters for a soft center.

Quick Answers

Do I need to blend the cottage cheese or can I leave it lumpy?

You really do want to blend it until it is completely smooth. This gets rid of the little curds so your dough is even and the cookies do not end up with weird bumpy bits.

If you skip this step, the cottage cheese texture can show up in the finished cookies, which is not what you want here. A blender or food processor makes it super quick.
