First, get your Keto Lemon Curd ready and pop it in the fridge to cool down while you prepare the crust.
To Make the Crust:
Preheat your oven to 350°F (175°C).
In a bowl, combine the almond flour, sweetener, beaten egg, melted butter, and vanilla extract. Mix everything until it's well combined.
Press this mixture evenly into a 9x9-inch baking dish lined with parchment paper – this makes lifting it out super easy!
Bake for 15-17 minutes, or until the edges are lightly golden. Let it cool completely at room temperature before moving on.
To Make the Cheesecake Layer:
In a mixing bowl, whip the softened cream cheese with a hand mixer until it's light and fluffy.
Add the sour cream, heavy cream, sweetener, and vanilla extract. Continue mixing until the mixture is smooth and fully combined.
Once the crust is cool, gently spread the cheesecake mixture over it using an offset spatula. Place it in the fridge to chill for at least 1 hour, allowing it to firm up a bit.
To Make the Lemon Layer:
Carefully spread the cooled lemon curd evenly over the chilled cheesecake layer.
Return it to the fridge for another hour, or until this layer is firm enough to add the whipped topping without mixing.
To Make the Whipped Topping:
Pour the cold heavy cream into a chilled mixing bowl and whip with a hand mixer until soft peaks form. (A cold bowl helps a lot!)
While the mixer is still running, slowly add the sweetener and vanilla extract. Once you have stiff peaks, add the softened cream cheese and mix just until smooth.
Spread the whipped cream over the lemon layer. You can make it smooth or create a fancy design.
Chill the entire dessert in the fridge for at least 4 hours, though overnight is best for perfectly set layers. Patience is key for this beautiful dessert!
