Keto Blueberry Cheesecake Ingredients

There are three parts to make this Keto Blueberry Cheesecake; the almond crust, vanilla cheesecake and the blueberry lemon swirl. This is what you will need for each part:

Almond Crust

  • almond flour
  • almonds
  • butter
  • cinnamon
  • sukrin gold

Vanilla Cheesecake

  • cream cheese
  • sour cream
  • powdered monk fruit / erythritol sweetener
  • vanilla
  • lemon juice
  • eggs

Blueberry Swirl

  • blueberries – fresh or frozen
  • monk fruit / erythritol sweetener
  • lemon zest

Sukrin GoldSukrin Gold is a low carb sweetener that is made to mimic brown sugar. I use it all the time in recipes like this Low Carb BBQ Sauce or these No Bake Peanut Butter Chocolate Freezer Cookies. If you don’t have any, you could replace it with the monk fruit / erythritol.

Monk Fruit / Erythritol Sweetener – This is my go-to sugar free sweetener. My favourite brands are either Lakanto or SoNourished. Either way, I buy their granular version and make my own powdered when I need it! To make powdered, simply grab a clean coffee grinder, add about 1/4 cup granular sweetener and blitz for a couple of moments.. that’s it! Perfectly powdered sweetener, ready for your sweet treats!

How to make a Keto Blueberry Cheesecake

Cheesecake making, or as I like to call it, Cheesecaking 🤓, is definitely a process, but it’s a labour of love. Start with making the sauce so that it can cool for when the cheesecake layer is ready.

Blueberry lemon sauce

Combine the blueberries in a small saucepan with the granular erythritol and lemon zest. Bring to a boil then reduce to a simmer. Cook for 10 minutes. Use an immersion blender to puree the sauce until smooth, then set that goodness aside.

Almond Crust

Preheat your oven to 350° and move the rack to the center. Cover the bottom of an 8″ springform pan and as much of the sides as possible with one sheet of heavy duty tin foil. This is to prevent leaks when the cheesecake is baked in a water bath. Spray the inside of the pan with oil and set aside.

In a medium bowl combine melted butter, almond flour, finely minced almonds, cinnamon and sukrin gold. Mix well then press into the bottom of the prepared springform pan with a fork. Bake in the preheated oven for 10 minutes, then remove and set aside.

Vanilla cheesecake

Using a stand mixer with the paddle attachment (or a big ol’ bowl and an electric hand mixer.. no, please don’t try to do this with a whisk 😬) whip the room temperature cream cheese until smooth, with no lumps remaining. Scrape the bowl.

Add sour cream, stir that in well, then mix in the powdered erythritol until smooth. Avoid over mixing and scrape the bowl often to avoid unmixed batter that can get stuck to the bottom of the bowl. Mix in 1 egg at a time while scraping in between additions, then stir in the vanilla and lemon juice. Pour into the springform pan, over top of the crust.

Swirl it

Let’s make this beauty! Dollop the blueberry sauce all around the cheesecake in little amounts, about 1/2 to 1 tbsp each.

Now take a butter knife or chop stick and swirl it back and forth until all the little blobs of blueberry sauce have been swirled into the cheesecake and you’ve created a beautiful design.

Bake it

Bring a kettle of water to boil, then place your cheesecake pan inside a baking dish. Once the kettle is ready, pour the boiling water into the baking dish, just until there is about a cm of water.

You want to make sure the top of the water doesn’t reach the top of the tin foil, otherwise it will go inside the pan and ruin your cheesecake… Not a lot of people like soggy cheesecake… 😬

Place the whole baking dish inside the oven, on the center rack, and bake for 45 minutes. The the outer edges will be puffy and the center of the cheesecake will still be jiggly.

Leave the cheesecake inside the oven, turn it off and prop the door open just a crack with a wooden spoon. Let the cheesecake sit inside the oven for 1 hour, then it can be removed and set on the counter for another hour before being refrigerated for a few hours, or overnight.

When ready to serve, remove the sides of the springform pan, then slice into 12 and enjoy!

Expert Tips

  1. You really can’t go wrong when making cheesecake. However, there are certain things you can do to drastically increase the dreaminess this Keto Blueberry Cheesecake brings. I’ve listed them in the recipe, but if you want some pro tips, check out my Cheesecake Tips post.
  2. Make sure you have all your ingredients at room temperature. This is important because you want each ingredient to combine easier. The easier they combine, the less you have to beat your mixture. The less you beat your mixture the less air bubbles you have and the more likely you are to have a lump free cheesecake.
  3. It’s important to get scrape your bowl often and make sure your spatula is getting all the way down to the very bottom of your bowl. Cream cheese can get stuck down there, making it difficult to mix into the batter the more liquid ingredients you add.
  4. Have fun with the swirl! The more, smaller dollops of blueberry sauce, the better.
  5. Be very cautious with the water bath – Make sure to not pour too much boiling water into the pan. Keep below the top of the tin foil so that the water cannot find its way inside the cheesecake.
  6. Don’t over bake that beauty! The edges will be puffy and may start to crack and the center will still be jiggly. It’s ready! Shut that oven off!
  7. It’s important to let your cheesecake cool completely before trying to dive in – I know, it’s a long wait, but a wait worth having!

Swirl flavour ideas

This Keto Blueberry Cheesecake is absolutely interchangeable. Sweet, right?What berries do you love? What is in season right now?

You can absolutely switch out the blueberries for the same amount of raspberries, strawberries or blackberries. I would recommend keeping the lemon with any flavour change up. As for the carbs? Here is what a slice of each looks like:

  • Blueberry: 7.1 g net carbs.
  • Raspberry: 5.9 g net carbs.
  • Strawberry 6.1 g net carbs.
  • Blackberry 5.7 g net carbs.

*If you choose raspberries or blackberries, I recommend pushing them through a strainer like this one instead of using an immersion blender, to remove all the seeds before it is cooled and swirled into your cheesecake.

How to store Keto Blueberry Cheesecake

Refrigerator

You want to keep your cheesecake in the fridge. Once it has fully cooled to the refrigerator temperature, it can be wrapped tightly with plastic or kept in an air tight container.

You don’t want to wrap it while it’s still warm, because the cheesecake will form condensation which will drip from the plastic, causing super ugly marks on all your beautiful work! It will last for 5-6 days in the fridge. Got leftovers?

Freezer

What?! You’ve got leftovers?! Lucky you!!! I rarely get cheesecake leftovers. Apparently I have to stop inviting people over when I make them! Every now and again I’ll have leftover cheesecake and the best way to keep it for longer than 5-6 days is by freezing it. Here’s how:

Line a baking sheet with wax paper. Slice the cheesecake into single serve slices and place around the baking sheet. Make sure not to let them touch each other, or they will stick together. Freeze until firm, then wrap each piece in wax paper and place inside large freezer safe ziploc bags.

This Keto Blueberry Cheesecake will last 6-8 months in the freezer. Well, that is how long it would stay good for, but who knows how long it will last! I’m sure you’ll have this creamy, blueberry goodness, whispering your name late into the night…
