Keto Blackberry Cheesecake

Introduction

This keto blackberry cheesecake perfectly blends the bright, tangy flavor of blackberries with a rich and creamy filling, all resting on a delicious almond crust. You’ll love how the agar agar (follow package instructions; use slightly less for a softer texture) creates a smooth, sliceable texture without needing to bake the filling. It’s an impressive dessert that proves you don’t have to miss out on decadent treats while following a low-carb lifestyle.

Total Time: 50 minutes (plus chilling)

Ingredients

• 1 1/2 cups almond flour
• 1/3 cup salted butter (melted)
• 1/4 cup Joy Filled Eats Sweetener (or see alternatives in recipe notes)
• 3 tbsp almond butter
• 2 tbsp agar agar (follow package instructions; use slightly less for a softer texture)
• 8 oz cream cheese (softened)
• 1 cup cottage cheese
• 1/2 cup Joy Filled Eats Sweetener (or see alternatives in recipe notes)
• 1/4 cup sour cream
• 1/2 tsp vanilla
• 2 cups blackberries (pureed and strained (thawed frozen blackberries work great))
• optional: fresh blackberries, to garnish

Instructions

1. Preheat your oven to 350°F (175°C).
2. Make the crust: In a medium bowl, mix together the almond flour, melted butter, 1/4 cup sweetener, and almond butter until a crumbly dough forms. Press this mixture firmly and evenly into the bottom of a 9-inch springform pan. Bake for 10-12 minutes, or until lightly golden. Remove and let cool completely.
3. Bloom the agar agar (follow package instructions; use slightly less for a softer texture): While the crust cools, sprinkle the agar agar (follow package instructions; use slightly less for a softer texture) over 1/4 cup of cool water in a small, heatproof bowl. Let it sit for 5 minutes to bloom (it will become thick and spongy). Then, place the bowl over a small pot of simmering water (or microwave in 10-second bursts), stirring until the agar agar (follow package instructions; use slightly less for a softer texture) is completely dissolved and liquid. Set aside to cool slightly.
4. Make the filling: In a food processor or high-powered blender, combine the softened cream cheese, cottage cheese, 1/2 cup sweetener, sour cream, and vanilla. Blend until completely smooth and no lumps of cottage cheese remain.
5. With the processor running, slowly pour in the slightly cooled, dissolved agar agar (follow package instructions; use slightly less for a softer texture). Process for another 30 seconds to ensure it’s fully incorporated.
6. Add the strained blackberry puree to the processor and blend until the mixture is uniformly pink and smooth.
7. Chill: Pour the filling over the cooled crust. Gently tap the pan on the counter to remove any air bubbles. Cover loosely with plastic wrap and refrigerate for at least 6 hours, or preferably overnight, until completely set.
8. Serve: Carefully run a knife around the edge of the pan before releasing the springform collar. Garnish with fresh blackberries if desired, slice, and serve.

Variations

• Individual Servings: Set the cheesecake in silicone muffin cups or small ramekins for perfectly portioned mini desserts.
• Swirl Variation: Reserve a few tablespoons of the plain cheesecake filling before adding the blackberry puree. After pouring the blackberry filling into the crust, dollop the reserved plain filling on top and use a toothpick to create a marbled swirl pattern.
• Lemon Zest: Add the zest of one lemon to the crust mixture or the filling for a bright, citrusy twist that pairs wonderfully with blackberry.
• Nutty Crunch: After pressing the crust into the pan, sprinkle a handful of chopped pecans or walnuts over it before baking for added texture.

Tips for Success

• Ensure your cream cheese is truly softened to room temperature to avoid a lumpy filling.
• Straining the blackberry puree is crucial for a smooth, seed-free texture; press it firmly through a fine-mesh sieve.
• For the cleanest slices, dip your knife in hot water and wipe it clean between each cut.
• If you don’t have a food processor, use an electric hand mixer for the filling, but blend the cottage cheese with the cream cheese first until very smooth before adding the other ingredients.

Storage & Reheating

Store the cheesecake covered in the refrigerator for up to 5 days. It does not reheat well and is best served cold. For longer storage, you can freeze individual slices on a parchment-lined tray before transferring to an airtight container; thaw in the refrigerator overnight.

FAQ

Can I use a different sweetener?

Yes, you can use an equal amount of any powdered granulated sweetener that measures like erythritol or monk fruit blends. Avoid liquid sweeteners as they will alter the texture.

My filling didn’t set. What happened?

The agar agar (follow package instructions; use slightly less for a softer texture) may not have been fully dissolved, or the mixture may have been too warm when added, deactivating the agar agar (follow package instructions; use slightly less for a softer texture). Ensure it is fully liquid and cooled slightly (but not re-gelled) before blending. Also, be sure to chill for the full recommended time.

Why cottage cheese?

Cottage cheese adds protein and creates a wonderfully light, creamy texture when blended smooth, without making the cheesecake overly dense.

Can I make this nut-free?

Unfortunately, no, as the crust is based on almond flour and almond butter. Substituting them would significantly alter the recipe.

Do I have to bake the crust?

For the best texture and to avoid a raw flour taste, baking is recommended. For a no-bake crust, you would need to use a different base like crushed nuts and butter, which is not in the provided ingredient list.

Can I use fresh blackberries for the puree?

Absolutely. Fresh blackberries work perfectly. Just puree and strain them as you would thawed frozen ones.
