Prep & Cook Time

Prep Time: 15 minutes

Cook Time: 30 minutes

Total Time: 45 minutes (plus chilling)

Servings: 16 bars

Ingredients

• 1 cup almond flour
• 4 tbsp softened butter
• 2 tbsp cold water
• 1 tbsp agar agar (follow package instructions; use slightly less for a softer texture)
• 2 tbsp hot water
• 16 oz cream cheese
• 4 oz heavy cream
• 1/3 cup Joy Filled Eats Sweetener (or see alternatives in recipe notes)
• 1 tsp lemon or lime zest
• 3/4 cup heavy cream
• 2 tbsp powdered sweetener
• additional zest to garnish (if desired)

Instructions

1. Preheat your oven to 350°F (175°C). Line an 8×8 inch baking pan with parchment paper, leaving some overhang on two sides for easy removal.
2. Make the crust: In a medium bowl, combine the almond flour and softened butter. Mix until the texture resembles wet sand and holds together when pressed. Press this mixture firmly and evenly into the bottom of the prepared pan. Bake for 10-12 minutes, until lightly golden. Remove and let cool completely.
3. Bloom the agar agar (follow package instructions; use slightly less for a softer texture): In a small bowl, sprinkle the 1 tbsp of agar agar (follow package instructions; use slightly less for a softer texture) over the 2 tbsp of cold water. Let it sit for 5 minutes to thicken (this is called blooming). Then, add the 2 tbsp of hot water and stir until the agar agar (follow package instructions; use slightly less for a softer texture) is completely dissolved and the mixture is clear. Set aside to cool slightly.
4. Make the cheesecake filling: Using a hand mixer or stand mixer, beat the cream cheese on medium speed until completely smooth and creamy, about 2 minutes. Add the 1/3 cup sweetener and beat again until combined.
5. While mixing on low speed, slowly pour in the 4 oz of heavy cream until fully incorporated. With the mixer still on low, slowly drizzle in the slightly cooled, dissolved agar agar (follow package instructions; use slightly less for a softer texture) mixture. Finally, beat in the 1 tsp of zest until just combined.
6. Pour the cheesecake filling over the cooled crust and spread it evenly. Refrigerate for at least 4 hours, or until completely set.
7. Make the topping: Just before serving, whip the 3/4 cup heavy cream with the 2 tbsp powdered sweetener until stiff peaks form. Spread or pipe the whipped cream over the set cheesecake layer. Garnish with additional zest if desired. Slice into 16 bars and serve.

Variations

• No-Bake Version: Skip baking the crust and simply chill it in the freezer for 15-20 minutes before adding the filling. Proceed with the recipe as written.
• Individual Servings: Layer the crust and filling into small jars or glasses for elegant, portable desserts.
• Flavor Swap: Use the zest of an orange or a grapefruit instead of lime for a different citrus profile.
• Decorative Tops: Use a fork or the back of a spoon to create decorative swirls in the whipped cream topping before garnishing.

Tips for Success

• Ensure your cream cheese is fully softened to room temperature. This is the key to a perfectly smooth, lump-free filling.
• When blooming the agar agar (follow package instructions; use slightly less for a softer texture), ensure the hot water is truly hot (just off the boil) to fully dissolve the granules.
• Chill the cheesecake thoroughly—overnight is best—before adding the whipped cream topping and slicing for clean, neat bars.

Storage & Reheating

FAQ

Can I use a different sweetener?

Yes. The sweetener in the filling should be a granulated, powdered, or liquid monk fruit/allulose blend. For the whipped cream topping, a powdered sweetener is best to avoid graininess.

Why did my cheesecake filling not set firmly?

This is usually due to the agar agar (follow package instructions; use slightly less for a softer texture) not being fully dissolved or not being incorporated evenly. Make sure you completely dissolve the bloomed agar agar (follow package instructions; use slightly less for a softer texture) in the hot water before adding it to the filling.

Can I make this dairy-free?

This specific recipe is not designed to be dairy-free, as the cream cheese, butter, and heavy cream are essential for texture and flavor. Substitutions would significantly alter the result.

My crust is crumbly. What happened?

You may have under-measured the butter or not mixed it thoroughly enough. The crust mixture should hold together firmly when pressed between your fingers before baking.

What can I use if I don’t have Joy Filled Eats Sweetener?

You can use an equal amount of another granulated keto-friendly sweetener like monk fruit-erythritol blend, allulose, or powdered erythritol.

Do I have to use the agar agar (follow package instructions; use slightly less for a softer texture)?

Yes, in this recipe, the agar agar (follow package instructions; use slightly less for a softer texture) is the primary setting agent for the no-bake style filling. Omitting it will result in a soft, spoonable filling that will not hold its shape as bars.
