Step 1: Prepare the Peanut Butter Base. In a medium saucepan, gently heat the salted butter, heavy cream, and your favorite low-carb sweetener over medium heat until it starts to bubble and thicken slightly. Remove from heat, then stir in the cacao butter and peanut butter powder until everything is wonderfully smooth. Pop this mixture into the refrigerator for at least 2 hours, or until it's the consistency of a thick pancake batter – you can even make this a day or two in advance!
Step 2: Craft the Creamy Filling. First, dissolve the gelatin completely in the cold water. In a separate large bowl, whip your softened cream cheese until it's light and fluffy. Gently fold in the dissolved gelatin, mixing well. Now, slowly incorporate the chilled peanut butter mixture from Step 1 into the cream cheese, blending until everything is perfectly combined and smooth.
Step 3: Assemble Your Cheesecake. For the crust, simply mix together the peanut flour (or peanut butter powder), almond flour, melted butter, and powdered sweetener. Press this mixture firmly into the bottom of an 8-inch springform pan. Carefully pour the creamy cheesecake filling over the crust. Place your cheesecake in the refrigerator to chill for a minimum of 8 hours – patience makes perfect!
Step 4: Drizzle with Sweet White Chocolate. Once your cheesecake is perfectly set, gently unmold it. For the delightful drizzle, melt the cacao butter in a small saucepan. Take it off the heat and stir in the powdered sweetener; it might clump a bit. Gradually add the heavy cream, one teaspoon at a time, until you reach a smooth, pourable consistency like melted chocolate. Artfully drizzle this over your gorgeous cheesecake and serve!
