Keto Strawberry Swirl Blondies

These keto strawberry swirl blondies are one of my favorite treats to make when I want something sweet but still want to stay on track with my low carb lifestyle.

They’re soft, buttery, and have this gorgeous pink strawberry swirl running through them that looks almost too pretty to eat. Almost.

The base is made with almond flour and sweetened with monk fruit, so they’re completely sugar free. You’d never guess it from the taste though.

Fresh strawberries get cooked down into a quick jam-like mixture that you swirl right into the batter before baking. It adds just the right amount of fruity sweetness.

If you’ve been looking for a keto friendly dessert that feels special but is still really simple to make, this is a great one to try.

Recipe Ingredients

For the Blondies

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

For the Strawberry Swirl

• 1/2 cup Fresh Strawberries, finely diced
• 1 tbsp Granulated Monk Fruit Sweetener
• 1 tsp Lemon Juice

How To Make

Step 1

Make the strawberry swirl first. In a small saucepan over medium heat, combine the diced strawberries, monk fruit sweetener, and lemon juice. Cook for 5 to 7 minutes, stirring and mashing the berries frequently until the mixture reduces to a thick, jam-like consistency.

Remove from heat and let cool for 10 minutes.

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 monk fruit sweetener. Add the eggs and vanilla extract and whisk until smooth and combined.

Step 4

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

Step 5

Spread the batter evenly into the prepared pan. Drop spoonfuls of the cooled strawberry mixture across the surface. Use a toothpick to swirl the strawberry into the batter in a beautiful marbled pattern, dragging through the dots in different directions.

Step 6

Bake for 24 to 28 minutes, until the top is lightly golden and the blondies are set in the center. A toothpick should come out with just a few moist crumbs.

Step 7

Let cool completely in the pan before slicing into 16 squares. The pink strawberry swirl creates a stunning contrast against the golden blondie.

Tips

Cook the Strawberry Mixture Down Enough

The strawberry swirl needs to be thick and jam-like before you use it. If it’s too runny, it will sink into the batter and disappear instead of creating that nice marbled look on top.

You’ll know it’s ready when you drag a spoon through it and the trail stays for a second before filling back in. It should coat the back of the spoon and not drip off easily.

If your strawberries were extra juicy and the mixture still looks loose after 7 minutes, just keep cooking it for another minute or two until it thickens up.

Let the Strawberry Mixture Cool Before Swirling

That 10-minute cooling time in the recipe isn’t optional. If you drop hot strawberry mixture onto the batter, it will melt into it and you won’t get clean swirls.

A cooled mixture holds its shape when you drop it on top, which is exactly what you need for a visible swirl pattern. It should be warm but not hot when you use it.

Don’t Swirl Too Much

When you drag the toothpick through the strawberry dots, do 4-5 passes and then stop. A lot of people keep swirling because they want it to look perfect, but the more you drag through it, the more the strawberry blends into the batter.

You want distinct streaks of pink against the golden batter. If you overwork it, you’ll end up with a uniform pinkish color instead of that nice contrast.

Quick, light drags in different directions give you the best-looking result.

Frequently Asked Questions

Can I use frozen strawberries instead of fresh?

Yes, frozen strawberries work just fine for the swirl. Just thaw them first and drain off any extra liquid before cooking them down in the saucepan, otherwise the mixture will be too watery and won’t thicken properly.

Fresh strawberries do give you a slightly brighter flavor and color, but frozen ones are a great option when strawberries aren’t in season.
