Keto Peanut Butter Swirl Cheesecake

Be sure to carve out some time to make this creamy peanut butter cheesecake since cheesecakes are a little more time-consuming to make, and you will have to wait for them to age in the fridge before enjoying them. 

But don’t let that deter you because cheesecakes are great make-ahead desserts, and this sugar-free cheesecake will be worth planning for. 

This recipe is precisely what you want when you want a dense, velvety smooth, melt-in-your-mouth cheesecake that also needs to be keto-friendly.

Is that too much to ask? Not if you’re in my world. I was determined to make a stunning showstopper of cheesecake that even my non-keto family would love. 

I knew I had a winner when my picky son, Matthew, kept raving about it. And the boy not only does not do keto, but he’s not even a fan of cheesecake! So yeah, this momma was proud.

This sugar-free peanut butter cheesecake features an almond flour crust that mimics a graham crust beautifully. It’s the perfect base for a creamy cream cheese base.

However, if you are not able to consume nuts, no problem; just substitute the almond flour 1:1 for sunflower seed flour; it works equally well. 

Although this peanut butter marble swirl cheesecake may appear complicated, it’s really not. A few basic steps, and soon you will be enjoying this dessert.

You should know I prefer to bake my cheesecakes in a water bath to ensure no surface cracks. It’s the only way to guarantee consistent results.

This is probably what will make you the most effort as far as this recipe goes. 

When mixing your cheesecake batter, you’ll want to beat the cream cheese and sugar substitute until it’s velvety smooth.

But, when it comes time to add the eggs, you want to be sure NOT to overbeat. Add the eggs and mix on low until just incorporated. Over-mixing is a sure way to get cracks on the surface of your cheesecake.

Step By Step Process For Making This Low Carb Peanut Butter Cheesecake

Make sure your cream cheese and eggs have come to room temperature for a minimum of two hours before you begin to make the cheesecake.

Begin by making the almond crust for the cheesecake. Preheat the oven to 350 degrees, then lightly grease the bottom of a 12-inch springform pan.

Then melt the unsalted butter. In a medium-sized bowl, add the almond flour, sugar substitute, and sea salt, and combine well.

Add the melted butter and combine the mixture until fully incorporated. Mix with a wooden spoon or spatula.

Once combined, add the almond mixture to the bottom of the springform pan. Use the bottom of a glass cup to press the mixture evenly into the pan.

Bake the crust in the preheated oven for 20-25 minutes until the crust is lightly browned.

While the crust bakes, proceed to make the filling. Be sure to allow the keto almond crust to cool completely before adding the cheesecake batter.

Reduce the oven temperature to 300 degrees and proceed to make the cheesecake batter.

Make sure your cream cheese and eggs have come to room temperature for a minimum of two hours before you make the filling.

Low-Carb Peanut Butter Cheesecake Filling

In a large stand-up mixer or a large mixing bowl using an electric handheld mixer, beat softened cream cheese and sugar substitute at a high setting. Combine until well incorporated.

Next, reduce the speed of the mixer to low speed and add the whole eggs and egg yolks one at a time. Stop and scrape the bowl at least two times to make sure the batter is mixed properly.

Then add vanilla extract and sea salt. Combine the mixture until the batter is fully incorporated and velvety smooth. Be careful not to over-mix.

Make sure you stop and scrape the bowl a couple of times during this process.

Lightly grease the sides of the springform pan with the baked almond crust.

Reserve 2 cups of the vanilla cheesecake batter for the peanut butter swirl.

Proceed to make the peanut butter swirl. Melt peanut butter and coconut oil together in the microwave for 30 seconds. Set aside.

Pour the vanilla cheesecake batter into the cooled almond crust. Using an offset spatula, evenly spread the top of the cheesecake batter.

Next, add spoonfuls of the peanut butter batter on top of the cheesecake.

Gently swirl the vanilla and peanut butter marble together using a skewer or a thin knife.

Bain-Marie (Water Bath)

Securely wrap the cheesecake pan with two large pieces of heavy-duty aluminum foil. To do so, I lay one piece of aluminum foil vertically and then stack another piece of foil horizontally.

I then bring up the foil up the sides of the pan, making sure the bottom and sides are tightly wrapped in foil. This is in preparation for the bain-marie.

Place your springform pan in a large roasting pan that is large enough to accommodate the pan without touching the sides.

Next, carefully pour boiling water into the roasting pan until the water reaches halfway up the sides of the springform pan.

Bake your cheesecake for 65-70 minutes until the cheesecake is set around the edges yet the center diameter (about 2 inches) of your cheesecake is still able to jiggle when you slightly move your pan. 

Do not overbake your cheesecake. It will continue to set as it cools.

Turn the oven off and allow the marble cheesecake to cool in the oven for one hour with the oven door slightly ajar.

Then place your cheesecake on a cooling rack and allow the cheesecake to cool further on the kitchen counter for at least another 60 minutes.

It’s key that the cheesecake is completely cool before storing it in the refrigerator.

Once your cheesecake has been allowed to cool on the kitchen counter, Run a knife around the springform pan and release the cheesecake.

Next, carefully wrap the cheesecake with plastic cling wrap and allow the cheesecake to sit in the refrigerator for at least 12 hours and up to 36 hours before serving.

Peanut Butter Hardshell Topping And Crushed Peanuts

In a small microwavable bowl, melt the tablespoon of coconut oil and combine it with creamy peanut butter for about 30-45 seconds. Set aside.

Drizzle the peanut butter topping on top of the cheesecake. 

When ready to serve, garnish the top of the cheesecake with salted peanuts.

Store leftovers in the refrigerator for up to 5 days or freeze them for up to 3 weeks. 

Choosing Your Peanut Butter

As far as which peanut butter to use for this recipe, there are some careful considerations you need to take to ensure success. For one, it should be a sugar-free option.

I know that’s not easy to source, but my favorite is from the brand Spread The Love peanut butter. It has zero sugar, salt, or palm oil, and it’s creamy.

The consistency is as close as possible to the stuff we grew up on, minus all the extras.

With that being said, if you can’t easily order that brand, you could use all-natural peanut butter that needs to be stirred.

Just keep in mind that you really want to mix it well before making the peanut butter swirl layer of this cheesecake.
