Line a baking sheet with parchment paper that will fit in your freezer.
Make the almond flour center: In a small bowl, knead the almond flour, oil, and confectioners' erythritol with your hands until a dough forms.
Divide into 12 equal pieces, roll into balls, and place on the prepared baking sheet.
Freeze while you prepare the next layer.
Make the cream cheese layer: In a medium bowl, combine the cream cheese, oil, and confectioners' erythritol with a fork or handheld mixer until smooth.
Divide the mixture evenly between two separate bowls.
Stir the 2 teaspoons (10 ml / 0.3 fl oz) of cinnamon into one of the bowls.
Chill the cream cheese: Place both bowls of the cream cheese mixture into the freezer for about 1 hour, or until firm enough to handle but not frozen solid.
Prepare the topping: In a small, shallow bowl, whisk together the granulated erythritol and 2 teaspoons (10 ml / 0.3 fl oz) of cinnamon.
Set aside.
Assemble the fat bombs: Remove the almond flour balls and cream cheese mixtures from the freezer. Scoop about a teaspoon of the plain cream cheese and a teaspoon of the cinnamon cream cheese.
Place one almond flour ball between the two scoops of cream cheese.
Roll the entire thing between your palms to form a larger ball, fully encasing the almond center.
Coat and chill: Immediately roll the completed ball in the cinnamon-sugar topping until fully coated.
Place it back on the parchment-lined baking sheet.
Repeat with the remaining .
Final chill: Freeze the finished fat bombs for at least 20 minutes to set completely before serving.
