Ingredients Method

Ingredients

  

• 1 1/2 cups fine almond flour
• 3 tablespoons powdered erythritol or allulose
• 1/4 teaspoon fine sea salt
• 1/4 cup unsalted butter, melted (or coconut oil for dairy-free)
• 1/2 teaspoon vanilla extract
• 16 ounces cream cheese, softened (full-fat, room temperature)
• 1/2 cup powdered keto sweetener (erythritol, allulose, or a blend)
• 1/3 cup sour cream (or full-fat Greek yogurt)
• 2 large eggs, room temperature
• 1 tablespoon vanilla extract
• 1/4 teaspoon fine sea salt
• 1 cup fresh or frozen strawberries, chopped
• 2–3 tablespoons powdered keto sweetener (to taste)
• 1 teaspoon lemon juice
• 1/4 teaspoon xanthan gum (optional, helps thicken)

Method

 

1. Prep the pan and oven: Heat oven to 325°F (163°C). Line an 8x8-inch square pan with parchment, leaving overhang for easy lifting.
2. Make the strawberry swirl: In a small saucepan, combine strawberries, sweetener, and lemon juice over medium heat. Cook 5–8 minutes until pulpy and juicy. Mash lightly. If using xanthan gum, sprinkle it over and whisk well. Simmer 1–2 more minutes to thicken. Let cool.
3. Mix the crust: In a bowl, stir almond flour, sweetener, and salt. Add melted butter and vanilla. Mix until it resembles damp sand and clumps when pressed.
4. Press and pre-bake: Press crust mixture firmly and evenly into the lined pan. Bake 8–10 minutes until lightly golden at the edges. Set aside to cool slightly.
5. Make the vanilla filling: In a mixing bowl, beat cream cheese on medium speed until smooth, about 1 minute. Add sweetener and salt; beat until fluffy. Mix in sour cream and vanilla. Add eggs one at a time, mixing on low just until incorporated. Do not overbeat.
6. Assemble: Pour the vanilla filling over the warm crust and smooth the top. Spoon small dollops of the strawberry mixture all over the surface.
7. Create the swirl: Drag a skewer, toothpick, or thin knife through the dollops in gentle figure-eights. Don’t over-swirl—visible ribbons look best.
8. Bake: Bake at 325°F for 25–32 minutes. The edges should be set, and the center should have a slight jiggle. Avoid browning on top.
9. Cool and chill: Let the pan cool on a rack for 1 hour. Then refrigerate at least 3 hours, preferably overnight, until fully set.
10. Slice and serve: Lift out using the parchment. Cut into 12–16 bars, wiping the knife between cuts for clean edges.

Storage Instructions

• Refrigerator: Store in an airtight container for 4–5 days.
• Freezer: Freeze bars on a sheet until solid, then transfer to a freezer-safe container with parchment between layers. Keep up to 2 months.

  Thaw in the fridge.

• Serving tip: For the best texture, let refrigerated bars sit at room temperature for 10–15 minutes before eating.

Benefits of This Recipe

• Keto-friendly and gluten-free: Almond flour crust keeps carbs low without sacrificing taste.
• Satisfying and creamy: Plenty of healthy fats from cream cheese and almonds to keep you full.
• Lower sugar impact: Uses keto sweeteners so you can enjoy dessert without a blood sugar spike.
• Make-ahead convenience: Chills well and improves in flavor by the next day.
• Simple ingredients: Mostly pantry staples with easy swaps for dairy-free options.

Common Mistakes to Avoid

• Overbaking the filling: If it’s fully firm in the oven, it will be dry after chilling. Pull it when the center still jiggles slightly.
• Using cold cream cheese or eggs: This can create lumps and overmixing. Bring ingredients to room temperature for a smooth batter.
• Over-swirling: Too much swirling blends the colors and can thin the top layer.

  A few gentle passes are enough.

• Skipping the pre-bake: The crust needs a short bake to set and stay crisp under the filling.
• Cutting too soon: Let it chill completely so the bars slice cleanly and hold their shape.

Alternatives

• Berry swap: Use raspberries or blackberries instead of strawberries. Adjust sweetener to taste.
• Dairy-free: Use dairy-free cream cheese and coconut cream in place of sour cream; coconut oil in the crust.
• Nut-free crust: Use a mix of sunflower seed flour and coconut flour (try 1 cup sunflower seed flour + 3 tablespoons coconut flour) with the same butter and sweetener.
• Lemon twist: Add 1–2 teaspoons lemon zest to the filling for a bright citrus note.
• Chocolate drizzle: After chilling, drizzle with melted sugar-free dark chocolate for a fancy finish.

FAQ

Can I use liquid sweetener instead of powdered?

Yes, but it can slightly change the texture. Powdered keto sweeteners blend smoothly and help keep the filling stable.

If using liquid, reduce by a tablespoon or two of sour cream to maintain thickness.

Do I need the xanthan gum in the strawberry swirl?

No, it’s optional. It just helps the swirl set and stay defined. If you skip it, simmer the strawberry mixture a bit longer to cook off excess liquid.

Can I bake this in a 9×9-inch pan?

You can, but the bars will be thinner and may bake a bit faster.

Start checking 3–5 minutes earlier.

How do I prevent cracks on top?

Use room-temperature ingredients, mix on low speed, and avoid overbaking. A slight jiggle in the center means it will set creamy without cracking.

What’s the best sweetener for a clean taste?

Allulose gives a smooth, non-cooling sweetness. Erythritol works well too but can have a slight cooling effect.

A blend often gives the best balance.

Can I make this crustless?

Yes. Grease and line the pan, pour in the filling, add the swirl, and bake. The texture will be softer, so chill thoroughly before slicing.

How many carbs are in each bar?

Counts vary by brand and cut size, but a typical 1/12 portion is around 4–6g net carbs.

Calculate with your specific ingredients for accuracy.
