Preheat the oven to 350°F / 180°C. Grease a 9″x5″ loaf pan, and line with parchment paper letting the edges of the paper hang over the edges. Cream the softened butter and sweetener together for 2-3 minutes.
Transfer the batter into the prepared loaf pan and level with the spatula. Bake for 45 minutes, tenting the pan with aluminum foil if the bread is browning too quickly.
Make the cream cheese frosting. Beat room temperature cream cheese, heavy cream, vanilla extract and powdered sweetener (I used Powdered Erythritol) together until frosting is light and fluffy.
Spoon the frosting onto the (cooled!) pumpkin bread and spread it with a spoon or spatula. Add pecans and a little Sukrin Maple Syrup if you like. Grate a little nutmeg over the top, slice and enjoy!
