Place the shredded zucchini in a colander, sprinkle with 1/4 teaspoon of salt, and toss gently. Let it sit for about an hour, then squeeze out all excess moisture.
Preheat your oven to 350°F (175°C) and grease a 9x9 inch metal baking pan.
Whisk together eggs, oil, brown sugar substitute, and vanilla. Fold in the drained zucchini.
Stir in almond flour, protein powder, cinnamon, baking powder, and remaining salt. Add nuts if desired.
Pour into pan and bake for 15-20 minutes until edges are golden. Cool completely.
For the frosting, beat cream cheese and caramel sauce until smooth. Mix in sweetener and extract. Spread over cooled bars.
