First, lightly grease a 6-inch springform pan and line the bottom with a circle of parchment paper.
In a medium bowl, whisk together the almond flour, powdered sweetener, cocoa powder, and salt.
Stir in the melted butter until the mixture forms lovely crumbles.
Press this delicious mixture firmly and evenly into the prepared pan. Place it in the freezer while you get the filling ready.
In a large bowl, beat the softened cream cheese on medium speed for 1-2 minutes until it's wonderfully creamy.
Scrape down the sides of the bowl and the beaters, then beat in the powdered sweetener.
Add the room-temperature Keto Irish Cream liqueur and beat on low speed until everything is just well combined and smooth.
Pour this luscious filling over your chilled crust, spreading it out evenly to the edges.
Gently tap the pan firmly on your counter a few times to release any pesky air bubbles.
Return the cheesecake to the freezer and let it freeze until firm, which will take at least two hours.
Once it's perfectly firm, carefully remove it from the freezer and run a sharp knife around the inside edge of the pan to loosen before removing the springform sides.
In a small saucepan over medium heat, combine the heavy cream, Keto Irish Cream liqueur, and optional allulose. Bring it to a gentle simmer.
Remove the saucepan from the heat, add the keto chocolate chips, and let them sit for a few minutes to melt.
Whisk until you have a smooth, glossy, and irresistible chocolate topping.
Drizzle generously over your beautiful cheesecake. Decorate with a few extra chocolate chips or whipped cream if you like!
