In a large bowl, mix almond flour, protein powder, espresso powder, and powdered sweetener until combined.
Add mascarpone cheese and brewed espresso, then stir or knead until a thick dough forms.
If the dough feels dry, add a teaspoon of espresso at a time until it holds together.
Use a small cookie scoop (or eyeball it) to form 1-inch balls, then roll them smooth in your hands.
Roll each ball in cocoa powder and place on a dish or tray.
Refrigerate for at least 30 minutes to firm up, then whisk together the mascarpone dip ingredients and serve alongside for dipping.
