2-Ingredient Cottage Cheese Brownies: Box Mix + Blended 4% Cottage Cheese

This is a two-ingredient, semi-homemade brownie method that uses a standard boxed brownie mix plus blended 4% cottage cheese as the liquid/fat component. The recipe yields a full 9x9-inch pan (about nine brownies) and was developed to be low-lift while producing a traditional pan of brownies.

Blended cottage cheese supplies the moisture and fat normally contributed by eggs and oil. The crucial step is blending: it breaks down the curds so the cottage cheese becomes a smooth, pourable liquid that mixes uniformly with the dry mix.

• Brownie mix: one standard box between 14.8 and 18.3 ounces. The recipe was tested with a 14.8-oz Kodiak mix and an 18.3-oz Duncan Hines mix. Different box sizes change batter thickness.
• Cottage cheese: 1 cup of 4% (full-fat) cottage cheese, blended until smooth.
• Water: optional, added only if needed to reach a thick-but-spreadable batter. In testing, 1–1.5 tablespoons total was used with larger boxes.

1. 1Blend the cottage cheese until it is completely smooth and as thin as milk or cream.
2. 2Stir the blended cottage cheese into the dry brownie mix.
3. 3If the batter is too thick to spread, add water 1 tablespoon at a time until it reaches a thick but spreadable consistency.

1. 1Cool in the pan 10–15 minutes before slicing. Refrigerate leftovers after cooling.

• Blend thoroughly: unblended curds will leave visible pieces and uneven texture.
• Judge by consistency, not brand: because box sizes vary, base water additions and doneness on batter feel and visual cues rather than fixed volumes.

• Doneness cues: set edges and moist crumbs on a toothpick. A completely clean toothpick indicates the brownies may be overcooked.

Let the brownies cool before covering them to avoid condensation, then store covered in the refrigerator because they contain cottage cheese.

Home bakers who want a low-effort pan of brownies and are open to substituting blended full-fat cottage cheese for eggs and oil. It's useful if you prefer semi-homemade shortcuts or want a slightly different macronutrient profile than a conventional boxed-mix method.
