Preheat your oven to 350°F (175°C). Grease and line your cake pans.
In a bowl, cream softened butter and sweetener until fluffy. Add vanilla and optional molasses.
Mix in eggs one at a time, beating well after each.
Stir in almond flour, baking powder, cinnamon, and salt until just combined.
Fold in grated carrots and 1 cup chopped pecans.
Divide batter into pans and smooth the tops.
Bake for 35–40 minutes, or until a toothpick comes out clean.
Let the cakes cool completely before frosting with sugar-free cream cheese frosting.
