Preheat oven to 350°F. Lightly oil a small pound cake pan.
In a mixing bowl, beat together butter, sweetener, and stevia until smooth. Add cinnamon and cream cheese and mix again until fully incorporated with no lumps.
Stir in rum, raisins, orange peel, almond flour, and baking powder. Mix until the batter is uniform.
Pour into prepared pan and bake for 45 minutes.
Allow to cool completely before removing from the mold.
