Prepare an 8” bread pan with parchment paper or cooking spray.
Preheat oven to 350 F.
In a medium bowl, beat eggs (4).
Add pumpkin puree (3/4 cup), unsalted butter (1/4 cup), vanilla (2 teaspoons) and stir to combine.
In a separate bowl, add almond flour (2 cups), coconut flour (1/2 cup), erythritol (3/4 cup), baking powder (1 1/2 teaspoon), salt (1/2 teaspoon), cinnamon (1 tablespoon), and nutmeg (1 teaspoon). Stir to combine.
Add dry ingredients to wet ingredients and mix until fully combined.
Pour batter into prepared bread pan.
Cook for 1hr - 1hr 10 minutes, or until a toothpick in the center of the loaf comes out dry.
Meanwhile, using an electric mixer, combine the frosting ingredients in a small bowl.
Allow the bread to cool before adding the frosting. Enjoy!
