Fudgy Cocoa Brownies

Whip out the parchment paper and prepare for your kitchen to smell amazing. The recipe makes the perfect starter brownie for keto diet newbies: A blend of creamy butter, almond flour and xylitol bakes into an ultra-tender bar with a fudgy mouthfeel. Each brownie is also 1 gram of net carb, so this recipe is keto-friendly enough to enjoy every night of the week.

Keto Skillet Brownies

A cast iron skillet creates the crisp crust and gooey center in this keto brownie recipe. Get the freshest walnuts you can (and shell them yourself if possible). If you don’t tolerate legumes, swap the peanut butter drizzle for fresh almond butter. Top with melty keto ice cream for a restaurant-worthy dessert at only 3 grams of net carbs per serving.

Low Carb Brownies With Almond Butter

The oils from almond butter add extra moisture and chew to these keto brownies, and you can make them in about 20 minutes. Since they contain low-carb ingredients like coconut flour and erythritol, they’re the perfect keto dessert at 2 grams of net carbs per serving. Grind up your own almond butter from high-quality nuts to keep this brownie recipe more Bulletproof. Allow these low-carb brownies to come to room temperature before serving—they need to cool before you slice.

Low Carb Macadamia Nut Brownies

High-fat macadamia nuts are one of the most keto-friendly nuts around, and they add a delicious crunch to this brownie recipe. And since each serving contains about 26 grams of fat (and under 3 grams of net carbs), they make a good alternative to fat bombs when you’re looking to switch up your snacks. For the most Bulletproof results, use high-quality nuts and high-quality instant coffee.

Collagen Protein Brownies

Support healthy skin, bones and joints with the collagen peptides in these nutty keto brownies. No special extra steps, either: Just mix wet and dry ingredients, add to your baking dish and bake. To make these more Bulletproof, choose almond flour over gluten-free baking flour and swap almond milk with full-fat coconut milk—you’ll still get keto-friendly results at 3 grams of net carbs per brownie.

Keto Brownie Bites

These little bites are perfectly portioned so you’re not tempted to eat the whole pan. And since each bite has 1 gram of net carb, they’re also easy on your macros. We recommend using grass-fed butter or Bulletproof Grass-Fed Ghee when the recipe calls for it. Use a toothpick to test doneness: Insert a toothpick into the center of a brownie bite. If it comes out wet, your brownies aren’t done yet.

Flourless keto brownies

Basic Flourless Keto Brownies

Since these flourless keto brownies use a small amount of gluten-free arrowroot powder to soak up the wet ingredients, you’ll still get a perfectly fudgy texture without conventional or nut flours. While portion sizes are small, each brownie is only 3 grams of net carbs.

This recipe calls for a sugar-free granular sweetener—such as Lakanto monkfruit sweetener, stevia or Swerve sweetener—to keep it keto-friendly. We like using birch xylitol or erythritol sweeteners in keto dessert recipes for a sugar substitute without an aftertaste.

Keto Flourless Mocha Brownies

No flour needed for these keto brownies—not even almond or coconut flour. With a rich blend of unsweetened cocoa powder, espresso powder, vanilla extract and baking chocolate, this recipe bakes up into a sweet mocha-flavored dessert with under 2 grams of net carbs per serving. (Bonus: They’re also nut-free.)

Fudgy Flourless Keto Brownies

Get ready to make your non-keto friends say “OMG, this is keto?!” Thanks to extra fiber from whole psyllium husks, these keto brownies hold up well without any kind of flour. Plus, that fiber cuts net carbs down to 2 grams per serving while still delivering a sweet and chocolatey taste. Heads up: Psyllium husk can cause bloating and stomach upset, so have it in moderation.

No-Bake Brownie Bites

With these keto brownies, you won’t even need to wait for the oven. Just throw ingredients into a food processor, press your brownie batter into a dish and slice for chewy chocolate perfection. We recommend using high-quality raw nuts and nut butters for the most Bulletproof (and tastiest) results. For extra flavor and texture, add in sugar-free chocolate chips, or top with coconut flakes.

Flourless Paleo Vegan Zucchini Brownies

Don’t worry, you can’t taste the veggies! Coconut oil and shredded zucchini keeps these keto brownies perfectly moist. Plus, with a fudgy texture and 2 grams of net carbs per brownie, you won’t even miss boxed brownie mix—and the total time is just 30 minutes. Pro tip: Pick up an organic zucchini and use erythritol or birch xylitol as your granulated sweetener.

Keto Rocky Road Bars

Keto-friendly marshmallows and Bulletproof Fudge Brownie Collagen Protein Bar chunks are surrounded by a rich, chocolatey fudge made with Bulletproof Brain Octane C8 MCT Oil, cacao butter and potassium-rich cacao powder. At just 2.5 grams of net carbs per serving, this show-stopping dessert is an easy way to satisfy a chocolate craving (and your macros).

Double Chocolate Keto Brookies

Like crisp edges on your keto brownies? These treats are made for your sweet tooth. This recipe marries crisp cookies with chocolatey brownies, all with 2 grams of net carbs per serving. Plus, it uses keto pantry staples like nut butter, baking powder and gelatin. For a Bulletproof brookie, choose organic raspberries and a high-quality almond butter, and whip up this recipe with grass-fed Bulletproof Collagelatin.

Keto Brownie Cookies

This keto dessert is made for soft brownie lovers—with minimal prep time. Scooping batter thick onto the baking pan keeps these cookies fudgy while only setting you back about 4 grams of net carbs. To keep these keto brownie cookies Bulletproof, use grass-fed melted butter and unsweetened dark chocolate chips.
