These keto blondies are gooey and chewy, and everything you want in a low carb dessert bar. Made with brown butter and chocolate chips, they practically melt in your mouth!
When it comes to dessert, I don’t discriminate. I really love it all, and my vast archive of keto dessert recipes proves this beyond a doubt. I love fudgy Keto Blondies, tender Keto Chocolate Chip Cookies, and creamy Keto Custard.
But these Keto Blondies have a special place in my heart. They check all the boxes for a mouthwatering dessert. A wonderful texture, rich, sweet flavor, and they take only 35 minutes to make.
This is the recipe I whip up whenever I need a sweet treat I can share with non-keto folk. They always please!
Brown butter is the secret sauce
Keto blondies with chocolate chips are pretty tasty as it is, but the addition of brown butter takes them up a few notches.
If you’ve never tried brown butter, you need to run to your kitchen right now, plop a stick of butter in a pan and turn the heat to medium. Don’t walk away, don’t go anywhere, stand nearby and stir frequently. Four or five minutes later, you will have an amber liquid with a nutty, almost caramel-like flavor.
Brown butter is amazing in both sweet and savory recipes. One of my family’s favorite dinners is Brown Butter Chicken with Sage and Prosciutto. It’s fabulous as a sauce on Air Fryer Pork Chops, and it’s the secret to my delicious Keto Mushroom Soup.
Add brown butter into any sweet recipe and you get unparalleled flavor. Cookies, blondies, and cake can all get a boost from browned butter. These keto blondies are more tender and rich than they would be with regular butter.

Ingredients you need

- Butter: Since the browned butter is the star of this recipe, choose a high quality butter. I like to use salted butter but you can use unsalted if you don’t like salty-sweet flavors.
- Almond flour: These keto blondies work best with finely ground, blanched almond flour.
- Brown sugar substitute: The flavor of this recipe is enhanced with a brown sugar substitute like Swerve or PureCane. The new Swerve formula works just as well as the old here.
- Collagen: The addition of some collagen protein (aka collagen peptides) makes the bars more gooey and tender. See the Expert Tips section for substitutes.
- Eggs: A whole egg plus an egg yolks also helps the consistency.
- Sugar-free chocolate chips: Either Lily’s or ChocZero work well here.
- Pantry staples: Baking powder, vanilla extract, and salt.
Step-by-step directions
1. Brown the butter: Place the butter in a medium skillet over medium heat. Cook, stirring frequently, until the butter becomes a deep amber, 4 to 5 minutes. Remove and let cool.
2. Whisk the dry ingredients: In a large bowl, whisk together the almond flour, sweetener, collagen protein, baking powder, and salt.
3. Stir in the wet ingredients: Stir in the egg, egg yolk, browned butter, and vanilla extract until well combined. Stir in the chocolate chips, saving a few for the top of the blondies.
4. Bake the blondies: Press the dough evenly into a greased 8×8 inch square pan and top with the remaining chocolate chips. Bake 15 to 20 minutes at 325ºF, until just set and golden brown. Let cool and cut into squares.
Expert tips
Make the brown butter first. It needs to cool for a before you add it to the keto blondies. If it goes in to warm, it can cook the eggs and melt the chocolate chips.
Watch that brown butter carefully! Depending on how much you’re making, it can take only a few short minutes. It will foam quite a bit so you may need to push aside some of the foam to see the color.
Don’t want to use collagen? Simply use another ¼ cup of almond flour instead.
Feel free to add in some other fun ingredients like chopped pecans or white chocolate chips. I used some of the new keto candies from Max Sweets on them recently, and the kids went nuts for them!
Sweetener Options
I think Swerve Brown is perfect in these keto blondies, as it enhances the caramel-like brown butter flavor. But you can really use any granular sweetener you like best. Do keep in mind that allulose sweeteners will make the blondies brown a little faster so keep your eye on them.
