Preheat oven to 325°F and grease a 9×5 loaf pan, then line it with parchment paper.
In a large bowl, whisk the almond flour, powdered sweetener, baking powder, and salt until combined.
In another large bowl, whisk the eggs, melted butter, orange extract, orange zest, and vanilla extract until smooth.
Add the dry ingredients to the wet mixture and stir until just combined. The batter will be thick.
Pour the batter into the prepared pan, smooth the top, and bake for 45–50 minutes or until a toothpick inserted in the center comes out clean.
Cool completely, then mix together cream cheese, powdered sweetener, and vanilla extract until smooth. Spread the frosting over the loaf and finish with fresh orange zest on top.

Notes
Use room-temperature ingredients for the best texture.
For stronger orange flavor, use up to 2½ teaspoon orange extract.
The loaf tastes even better the next day once the citrus settles
