Preheat the oven to 325° F and grease an 8x8" baking dish with butter or non-stick spray.
In a large bowl combine the butter, sweetener, egg, and strawberry extract until well combined and the sweetener is beginning to melt. Add the almond flour, gelatin mix, baking powder, and salt. Stir until combined.
Fold in strawberries if using. Then transfer this mixture to the prepared dish and spread into an even layer.
Bake for 18-20 minutes or until a toothpick inserted into the center of the bars comes out clean.
Once they are finished baking, set them aside to cool. Meanwhite, prepare the glze.
In a small bowl, combine the powdered sweetener, lemon juice, and lemon zest. Stir until smooth adding milk if needed to reach desired consistency. The glaze should be thin and pourable.
Once the bars have cooled, use a pasrty brush or spoon to spread the glaze over the bars. Sprinkle with additional lemon zest if desired. Serve immediately or store in the fridge for later and enjoy!
