Keto no bake blueberry cheesecake bars

 

🥣 Ingredients

You’ll have three components to prepare: the crust, the filling, and the blueberry topping.

For the Crust

Ingredient	Amount
Almond flour	1½ cups (168g)
Granulated erythritol (or your preferred keto sweetener)	¼ cup
Unsalted butter, melted	½ cup (1 stick)
Vanilla extract	½ tsp
Pinch of sea salt	optional

This gives you a buttery base that’s firm once chilled. Some recipes also add finely crushed nuts for extra texture.

For the Cheesecake Filling

Ingredient	Amount
Cream cheese, full‑fat, softened	16 oz (two 8‑oz blocks)
Powdered erythritol (or powdered allulose)	½ cup
Heavy cream (or coconut cream)	1 cup
Vanilla extract	1 tsp
Lemon juice	1 tbsp
Lemon zest (optional)	1 tbsp

If you can’t find powdered sweetener, simply grind granular erythritol in a clean coffee or spice grinder.

For the Blueberry Topping

Ingredient	Amount
Fresh or frozen blueberries	2 cups
Water	¼ cup
Powdered erythritol (or allulose)	2 tbsp
Lemon juice	1 tbsp
Xanthan gum (or glucomannan, optional for thickening)	½ tsp

👩‍🍳 Instructions (Total: ~20 min active + 4 hr chilling)

1. Make the crust. In a medium bowl, stir together the almond flour, granulated erythritol and salt, if using. Pour in the melted butter and vanilla, mixing until the texture looks like moist sand.

2. Press the crust into the pan. Line an 8×8‑inch baking dish with parchment paper, leaving some overhang on two opposite sides – this makes removing the bars much easier. Transfer the crust mixture and press it firmly into an even layer. A flat‑bottomed measuring cup works great for compacting it well. Set the pan in the refrigerator to chill while you prepare the filling.

3. Prepare the creamy filling. In a large mixing bowl, beat the softened cream cheese with an electric mixer for 2‑3 minutes, until it’s completely smooth and no lumps remain. Gradually add the powdered erythritol and beat for another 2 minutes, until the mixture is light and fluffy. Add the vanilla, lemon juice, and optional lemon zest, and mix until combined.

4. Fold in the whipped cream. In a separate bowl, whip the heavy cream (which must be very cold) to stiff peaks. Gently fold this whipped cream into the cream cheese mixture until it’s fully incorporated. Do this by hand, using a rubber spatula, to keep the filling airy and light.

5. Assemble the first layer. Take the chilled crust from the fridge. Spread the cheesecake filling evenly over the crust, smoothing the top with a spatula. Return the pan to the refrigerator while you make the blueberry topping.

6. Make the blueberry topping. In a small saucepan, combine the blueberries, water, 2 tbsp of powdered erythritol, and lemon juice. Cook over medium heat, stirring occasionally, for about 5‑7 minutes until the berries burst and the mixture thickens. If you’d like a firmer topping, whisk in the optional xanthan gum (or glucomannan) and cook for one more minute. Remove from heat and let the mixture cool to room temperature. This step is crucial so it doesn’t melt the filling.

7. Swirl and final chill. Spread the cooled blueberry topping over the cheesecake layer. For a pretty marbled effect, use a knife to gently swirl the topping into the filling. Cover the whole pan tightly with plastic wrap and refrigerate for at least 4 hours (overnight is even better) until it’s completely set.

8. Serve. Using the parchment paper overhangs, lift the whole block of cheesecake out of the pan. Place it on a cutting board and cut into 12 or 16 bars. For clean, sharp edges, dip your knife in warm water and wipe it dry between each cut. Store any leftovers in an airtight container in the fridge for up to a week, or freeze them for up to three months.

💡 Tips & Variations

• Thickening the topping. Xanthan gum is a classic keto thickener. Granular glucomannan (konjac powder) works just as well – use only about ¼ teaspoon, as it’s very strong. Gelatin (1 tsp soaked in 1 tbsp cold water, then stirred into the warm berries) is another excellent option.

• Sweetness level. If you’re new to keto sweeteners, start with slightly less than the recipe calls for. You can always taste the cheesecake filling (before adding the berries) and adjust to your preference.

• Blueberry alternatives. Fresh or frozen berries both work. If using frozen, do not thaw them first – cook them directly from frozen. You can also substitute an equal amount of raspberries or blackberries for a different flavor.
