Blueberry Lemon Sauce
Combine 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. Puree the sauce smooth with an immersion blender then set aside to cool.
Heat the oven to 350° and move the rack to the center. Wrap one sheet of heavy duty tin foil underneath the bottom, and up the sides, of an 8″ springform pan. (underneath the pan, not inside the pan) 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 sized microwave safe bowl, melt the butter, then add the almond flour, cinnamon, finely chopped almonds, sea salt and sweetener. Mix well then press into the bottom of the pan with a fork. Bake in the preheated oven for 10 minutes, then remove and set aside.
Using a stand mixer with the paddle attachment, whip the cream cheese until smooth, with no lumps remaining. Scrape the bowl.
Stir the sour cream in well, then mix in the powdered erythritol until smooth. Avoid over mixing and scrape often. Mix in 1 egg at a time while scraping in between each addition, then stir in the vanilla and lemon juice. Pour into the springform pan, over top of the crust.
Dollop the blueberry sauce all around the cheesecake in little amounts, about 1/2 to 1 tbsp each. 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.
Bring a kettle of water to boil then place your cheesecake pan inside the 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.
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.
Remove the sides of the springform pan, then slice into 12 and enjoy!
- 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.
- 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.
- 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.
- Have fun with the swirl! The more, smaller dollops of blueberry sauce, the better.
- 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.
- 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!
- 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!
