Preheat oven to 350℉. Grease a 8x4-inch loaf pan or line it with parchment.
Use a box grater on the largest holes to grate the zucchini. Use a clean kitchen towel or cheesecloth to squeeze as much liquid as possible from the zucchini.
In a large mixing bowl combine almond flour, sweetener, baking powder, cinnamon, and salt. Set aside.
In a medium bowl beat eggs. Stir in the zucchini, melted butter and vanilla.
Combine wet and dry ingredients together and stir until combined. Fold in the chopped nuts if using.
Spread batter into a loaf pan and bake for 45-55 minutes.
Cool in pans for 5 minutes, then remove and cool on a wire rack.
Notes
Check your baking powder’s expiration date; fresh powder ensures the best rise.Grate zucchini with the largest holes on a box grater and pat dry if too wet.Use room temperature eggs and butter for quicker blending.Line the pan with parchment paper for easy removal and clean-up.Sift almond flour before measuring to avoid dense, heavy bread.
