Simple Sugar Free Cottage Cheese Brownies

Here are my sugar free cottage cheese brownies, with rich cocoa powder, creamy cottage cheese, a touch of peanut butter, and your favorite sugar substitute for a guilt-free chocolate treat.

These brownies have become my go-to dessert when I want something sweet but don’t want all the sugar. They’re fudgy, satisfying, and nobody ever guesses the secret ingredient is cottage cheese!

What Kind of Cottage Cheese Should I Use?

For these brownies, any cottage cheese you have on hand will work just fine. Full-fat cottage cheese will give you the richest, fudgiest texture, while low-fat or fat-free versions will make slightly lighter brownies that are still totally delicious. The curd size doesn’t matter much here since you’ll be blending everything together anyway, so small curd, large curd, or even whipped cottage cheese are all fair game. If you want the smoothest possible brownie texture, just make sure to blend your cottage cheese really well with the other ingredients until there are no visible lumps remaining.

Options for Substitutions

These brownies are surprisingly flexible, so here are some swaps you can make:

• Cottage cheese: You can use ricotta cheese or Greek yogurt instead. Both will give you that creamy texture, though Greek yogurt might make the brownies slightly less dense. Stick with full-fat versions for the best results.
• Sweetener: Any granulated sweetener works here – erythritol, monk fruit, stevia, or allulose. If you’re not watching sugar, regular granulated sugar is fine too. Just keep in mind that different sweeteners have different levels of sweetness, so you might need to adjust the amount.
• Peanut butter: Almond butter, cashew butter, or sunflower seed butter all work great. Just make sure whatever you use is creamy, not chunky, and well-stirred before measuring.
• Cocoa powder: Don’t substitute this one – cocoa powder is what makes these brownies, well, brownies. Regular unsweetened cocoa powder is what you need here.
• Egg: For a vegan option, try a flax egg (1 tablespoon ground flaxseed mixed with 3 tablespoons water, let sit for 5 minutes). The texture will be slightly different but still tasty.

Watch Out for These Mistakes While Baking

The biggest mistake with cottage cheese brownies is not blending the batter long enough, which leaves lumpy cottage cheese curds throughout – make sure to blend for at least 60 seconds until completely smooth and creamy.

Another common error is cutting into the brownies too soon, as they need that full 30-minute chill time in the fridge to firm up properly, otherwise they’ll fall apart and seem undercooked even when they’re done.

Since these brownies are sugar-free and made with cottage cheese, they won’t look as “done” as regular brownies – a toothpick will come out with a few moist crumbs rather than completely clean, so don’t overbake them or they’ll turn dry and crumbly.

For extra richness, try using full-fat cottage cheese instead of low-fat, and if your batter seems too thick to pour easily, add a tablespoon of milk to thin it out slightly.

What to Serve With Cottage Cheese Brownies?

These brownies are pretty rich and fudgy on their own, so they pair really well with a cold glass of unsweetened almond milk or your favorite coffee. If you want to make them feel more like a dessert, add a dollop of whipped cream or a scoop of sugar-free vanilla ice cream on top while they’re still warm. Fresh berries like raspberries or strawberries are also a great choice since their tartness balances out the chocolate, and they keep things light if you’re watching your sugar intake. For an extra peanut butter kick, drizzle some melted peanut butter over the top or serve with a few apple slices on the side.

Storage Instructions

Store: These brownies keep really well in an airtight container in the fridge for up to a week. They actually taste even better the next day once the flavors have had time to meld together, so don’t be afraid to make them ahead of time.

Freeze: You can totally freeze these brownies for up to 3 months. I like to cut them into individual squares and wrap each one in plastic wrap before putting them all in a freezer bag. That way you can grab just one or two whenever a chocolate craving hits.

Enjoy: If you froze them, just thaw at room temperature for about 30 minutes or pop them in the microwave for 15-20 seconds for a warm, fudgy treat. They’re great straight from the fridge too if you like a firmer, more dense brownie texture.

• Calories: 370-430
• Protein: 23-28 g
• Fat: 16-20 g
• Carbohydrates: 26-32 g

Ingredients

• 1 cup cottage cheese
• 1 large egg
• 1/2 cup + 1 tablespoon cocoa powder
• 1/2 cup sweetener
• 2 tablespoons peanut butter
• 1/4 teaspoon salt
• 1/2 teaspoon vanilla extract

Step 1: Prepare the Batter

• 1 cup cottage cheese
• 1 large egg
• 1/2 cup + 1 tablespoon cocoa powder
• 1/2 cup sweetener
• 2 tablespoons peanut butter
• 1/4 teaspoon salt
• 1/2 teaspoon vanilla extract

Add the cottage cheese, egg, cocoa powder, sweetener, peanut butter, salt, and vanilla extract to a blender.

Blend on medium-high speed for 1-2 minutes until the mixture is completely smooth with no lumps or cottage cheese curds visible.

I find that taking an extra 30 seconds to ensure smoothness makes a huge difference in the final texture—lumps will create an uneven, grainy brownie.

Scrape down the sides of the blender if needed to ensure everything is fully incorporated.

Step 2: Prepare the Baking Dish and Pour Batter

• batter from Step 1

Line a 8×8 inch baking dish (or similar size small baking pan) with parchment paper, leaving slight overhang on two sides for easy removal.

Pour the batter from Step 1 into the prepared dish and smooth the top with a spatula for even cooking.

The parchment paper makes removal effortless once cooled, and I always prefer this method over greasing since these brownies are delicate.

Step 3: Bake the Brownies

Bake in a preheated 350°F (180°C) oven for 24-26 minutes, or use an air fryer at 320°F (160°C) for 19-22 minutes if you prefer.

The brownies are done when a toothpick inserted in the center comes out with just a few moist crumbs—they will continue to firm up as they cool.

These brownies are naturally dense and fudgy due to the cottage cheese base, so don’t overbake or they’ll become dry.

Step 4: Cool and Set Before Serving

Remove the brownies from the oven or air fryer and let them cool at room temperature for about 15-20 minutes until they’re no longer steaming.

Transfer to the refrigerator and chill for at least 30 minutes—this cooling time is essential for the brownies to set properly and become easier to cut into clean squares.

Once chilled, lift the brownies out using the parchment paper overhang and cut into 9-12 pieces depending on your desired size.
