In a mixing bowl, combine the almond flour and melted butter until well combined. Press the mixture into the bottom of a greased 9-inch springform pan to form the crust.
In a separate bowl, beat the cream cheese and sugar until smooth and creamy using an electric mixer.
Add the eggs one at a time, beating well after each addition.
Mix in the sour cream, heavy cream, and cocoa powder until fully incorporated.
Pour the filling into the prepared crust.
Bake for about 45-50 minutes or until the center is set and the top is slightly golden.
Remove the cheesecake from the oven and let it cool for 10 minutes.
In a small bowl, dissolve the espresso powder in the Kahlua liqueur.
Gently spread the Kahlua and espresso mixture over the top of the cheesecake.
Refrigerate for at least 4 hours or overnight to allow the flavors to meld.
