Sugar-Free Keto Blondies Recipe

Easy and buttery sugar free blondies make a quick and satisfying dessert that'll surely become of your favorites, what’s even better is that these are low carb and keto blondies too. No one will know you've lightened the recipe from the traditional recipe and instead you made healthy almond flour blondies everyone can enjoy. It's a WHOLE LOTTA YUM!

What is a blondie?

If you aren’t familiar with blondies and haven't had them before, they're basically blonde brownies and do not contain any chocolate.  At my house, my family will always request blondies over traditional brownies any day and for any occasion. They are soft and moist in the center, get their amazing flavor from brown sugar, and will satisfy any sweet tooth.

It wasn’t until I was in my 30's that I had the honor of tasting my first blondie. Although I'm incredibly sad it took that long in life. 

And I have to say, ever since tasting my first blondie, they've been the most often eaten and most often requested dessert in our house. 

While traditional blondies call for brown sugar, to lighten up this keto cookie recipe and make them no sugar and low carb, we used the Swerve brown sugar substitute, which is made from erythritol.

If you haven’t yet cooked with erythritol, it can be substituted one for one in recipes and comes in granular, brown, and confectioners sugar. Swerve has zero calories, it's natural, and measures, tastes, and bakes like sugar. Each serving only has 0 net carbs!

Some people say that erythritol has a cooling effect, so you feel a cooling sensation in your mouth when you are eating the treat. I felt this mildly myself and neither my husband or son reported that effect.

How do keto blondies compare to regular blondies?

Being that our traditional Blondie recipe is our favorite family dessert, I was skeptical about how swapping brown sugar for Swerve and regular flour for almond flour would be.

I’m happy to report the low-carb blondies were just delicious!  Stopping at 2 and not eating more was a tough one.

I was pleasantly surprised at how the keto blondies turned out, yet I will say these did not taste exactly like our regular go-to recipe. Instead, my son assumed it was just a different blondie recipe that I was trying that day.

I didn’t expect almond flour blondies to taste exactly alike because regular all-purpose flour and almond flour don’t taste the same, and while the swerve brown sugar substitute does taste exactly like brown sugar, they have a different texture.

Here's a photo of Swerve brown sugar substitute made from natural erythritol. It looks just like the real deal!

Since I didn’t want to consume the entire pan of low-carb and gluten free blondies by myself, happily my husband, son, and his friends helped me out and finished off the pan. Fortunately, I received rave reviews from all the boys.

Ingredients

Other than the two specialty ingredients (that are staples for keto baking), the other ingredients are basics many people already have at home.

Depending on where you live, you might or might not be able to find ingredients like almond flour or brown sugar erythritol. And even if you can purchase these locally, you can often buy them online for a lower price.

My two favorite places to buy are from here (most popular) and here (least expensive)--Plus 25% off with your first order

NEEDED INGREDIENTS:

• 1 ⅓ cup Almond flour
• 1 cup Swerve brown sugar substitute, packed
• ½ cup butter
• 1 teaspoon baking powder
• ½ teaspoon salt
• 1 egg
• 1 teaspoon vanilla extract

Another fantastic variation to blondies is adding low carb and sugar free chocolate chips. Hands-down, the best brand on the market is Lilys Dark Chocolate Premium Baking Chips. Lily's are natural, contain no sugar, are non GMO, vegan, and keto friendly too.  I will admit over a month-long period, I consumed an entire bag on my own (a few pieces at a time) without my family not knowing.

The chocolate chips on their own or a dessert in itself!

Recipe Tips

You might be tempted to overcook the low carb and gluten free blondies, which can result in a dry interior and crumbling texture.  To make them soft and moist and a little like heaven in the center, you need to undercook them slightly and pull them out of the oven. They will continue to cook as they sit.

What’s funny is this is actually a big debate in our house, I love things really soft and my husband likes them on the dryer side. So it always works out perfect because I can eat the center of any bar dessert and he wants to eat the dryer corner pieces.

Step by Step Instructions

Preheat your oven to 350° in place your rack in the middle position.

Lightly grease a 9x9 baking pan.

Whisk together the almond flour, baking powder, and salt in a small bowl.

In a medium sized bowl, melt the butter in the microwave. Add the brown sugar and mix well. Add the egg and vanilla, beating well until all is combined.

Stir the flour mixture into the butter/sugar mixture. If you're using chocolate chips, you'll want to add them at this point. Spread the mixture evenly in the prepared baking pan.

Bake the blondies for 20-23 minutes until the top of the blondies appears mostly set but not yet completely firm. The keto blondies will continue cooking after you pull them out of the oven.

I'd recommend checking the low carb gluten free blondies after 20 minutes and adding a few more minutes to the timer if needed.

Blondies are supposed to be soft and even a little gooey in the center, so if you cook them too long they'll actually turn out dry and crumbly. It's better the gluten free blondies get a little undercooked than overcooked.
