Preheat oven to 350F. Add the almond flour, cocoa powder, oat fiber, baking powder and salt to a large mixing bowl and whisk until well combined.
In a separate bowl, mix together the eggs, butter, sour cream, heavy cream, vanilla extract and Swerve. Pour the wet ingredients into the dry and mix just until combined. Add in the chocolate chips and continue mixing.
Using an ice cream scoop or two spoons, scoop the batter into a muffin pan lined with silicone liners or sprayed with nonstick spray. You can add a few chocolate chips over the top if you’d like, then bake for 20-23 minutes or until a toothpick when inserted, comes out clean.
