Keto Salted Caramel Stuffed Blondies

Salted caramel and blondies is one of those combinations that just works. And yes, you can absolutely make it keto friendly without losing any of that flavor.

I wanted to create a low carb blondie recipe that had something special going on in the middle. Not just a plain bar, but something with a soft caramel layer that makes every bite worth it.

The caramel uses brown monk fruit sweetener instead of regular sugar, and honestly, you can’t tell the difference. It gets thick and rich just like the real thing.

The blondie batter is simple to put together. You mix everything in one bowl, layer it with the caramel, and bake. No complicated steps or hard to find ingredients.

Once they come out of the oven, you top them with flaky sea salt while they’re still warm. That little bit of salt against the sweet caramel is what makes these so addictive.

Whether you’re following a keto diet or just trying to cut back on sugar, these are a dessert you’ll want to make again and again.

Recipe Ingredients

For the Caramel

• 3 tbsp Unsalted Butter
• 3 tbsp Heavy Cream
• 3 tbsp Brown Monk Fruit Sweetener
• 1/4 tsp Salt

For the Blondies

• 2 cups Almond Flour
• 1/3 cup Melted Unsalted Butter
• 1/2 cup Brown Monk Fruit Sweetener
• 2 large Eggs
• 2 tsp Vanilla Extract
• 1/2 tsp Baking Powder
• 1/4 tsp Salt
• Flaky Sea Salt for topping

How To Make

Step 1

Make the caramel first. In a small saucepan over medium heat, melt the butter. Add the brown monk fruit sweetener and stir until dissolved, about 2 minutes. Pour in the heavy cream and salt, then stir continuously for 3 to 4 minutes until the mixture thickens slightly.

Remove from heat and transfer to a small bowl. Place in the freezer for 20 minutes until it firms up enough to drizzle.

Step 2

Preheat your oven to 350°F (175°C). Line an 8×8 inch baking pan with parchment paper.

Step 3

In a large bowl, whisk together the melted butter and brown monk fruit sweetener. Add the eggs and vanilla extract and whisk until smooth and slightly thickened.

Step 4

Add the almond flour, baking powder, and salt. Stir with a spatula until a thick, uniform batter forms.

Step 5

Spread half the batter into the prepared pan. Drizzle the chilled caramel evenly over the top. Dollop the remaining batter over the caramel and gently spread it to cover as much as possible. It is fine if some caramel peeks through.

Step 6

Bake for 24 to 28 minutes, until the top is golden brown and the center is just set. A toothpick should come out with moist crumbs but no raw batter.

Step 7

Sprinkle flaky sea salt generously over the top while still warm. Let cool completely in the pan before slicing into 16 squares. The caramel center will be soft and gooey.

Tips

Freeze the Caramel Until It’s Thick but Still Drizzleable

The 20 minutes in the freezer is a rough guideline. What you’re looking for is a caramel that’s thick enough to hold its shape when you drizzle it, but not so solid that it clumps up.

If it’s too runny, it’ll sink straight to the bottom of the pan during baking and you won’t get that stuffed caramel layer in the middle. If it’s too firm, it won’t spread and you’ll get hard blobs instead of a gooey ribbon.

Check it around the 15-minute mark. It should slowly drip off a spoon in a thick stream. If it’s still watery, give it another 5 to 10 minutes.

Stir the Caramel Constantly on the Stove

Monk fruit sweetener doesn’t behave the same as regular sugar when heated. It can go from dissolved to grainy and scorched pretty fast, especially in a small saucepan.

Keep the heat at medium and don’t walk away. Stir the whole time from the moment you add the sweetener to when you take it off the heat. If you notice it starting to look dry or crystallized, lower the heat a bit and keep stirring until it smooths out.

Spread the Top Layer Gently

The second half of the batter goes on top of the caramel, and it will be sticky and thick. Don’t press down hard trying to make it perfectly even. That’ll push the caramel around and mix it into the batter instead of keeping it as a separate layer.

Use the back of a spoon or an offset spatula and gently dab and spread it across. Small gaps where caramel shows through are totally fine. Those spots actually caramelize a bit during baking and taste amazing.

Frequently Asked Questions

Can I use a different sweetener instead of brown monk fruit?

You can swap it for brown Swerve (erythritol-based) or a brown sugar-style allulose blend, and the blondies will still turn out great. These options behave similarly when baked and will keep the recipe keto friendly.

Avoid using liquid sweeteners like maple-flavored sugar-free syrup, since that will change the texture of both the caramel and the batter quite a bit.
