Line cookie sheets with parchment paper. Preheat the oven to 350°F.
In a large bowl, combine melted butter with a brown sugar replacement using a hand mixer. Mix until light and fluffy, about 3-5 minutes on medium-high speed. Add in softened cream cheese, and vanilla extract. Mix again until well combined, and make sure to scrape the sides of the bowl to ensure everything is incorporated. Add in the eggs one by one, mixing them into the batter completely.
In a separate medium bowl, combine almond flour, coconut flour, baking soda, xanthan gum, and kosher salt. Sift into the wet mixture, then fold in the ingredients gently to completely combine. Once combined, cover with plastic wrap and chill for at least 30 minutes in the fridge. After chilling the dough, using a large cookie scoop, scoop out large balls of dough and gently roll them into a round shape. Place them with plenty of space between each cookie on a parchment-lined cookie sheet. Bake for a total of 15-18 minutes, and if desired, remove the cookies from the oven about halfway through and bang the pan a few times to create a nice ripple effect in the cookies.
As soon as the cookies come out of the oven, use a large cookie cutter to "scoot" the cookies while they are still hot, giving them a nice round shape.
Allow them to cool for 10 minutes on the baking sheet, then transfer them to a cooling rack to cool completely.
Once completely cool frost with cream cheese frosting, then the strawberry sauce. Enjoy right away!
For best results, these should be enjoyed fresh. They can be stored in an airtight container in the fridge for up to 3-4 days. You can also store the ingredients separately in air-tight containers in the fridge for up to a week.
