01 - Preheat the oven to 350°F. Line a baking sheet with parchment paper.
02 - In a mixing bowl, cream together softened butter and granulated sweetener until light and fluffy using an electric mixer.
03 - Beat in the egg, vanilla extract, and heavy cream until the mixture is well combined and smooth.
04 - In a separate bowl, whisk together almond flour, coconut flour, baking powder, and sea salt until evenly distributed.
05 - Gradually add the dry ingredients to the wet mixture, mixing on low speed until a soft, cohesive dough forms.
06 - Scoop tablespoon-sized portions of dough onto the prepared baking sheet, spacing them 2 inches apart. Gently flatten each cookie with your fingers or the back of a spoon.
07 - Bake for 10–12 minutes, or until edges are just beginning to turn golden. Allow cookies to cool completely on the tray as they will firm up during cooling.
08 - Beat together softened butter and cream cheese until smooth and creamy. Add powdered sweetener and vanilla extract, then beat again. Gradually mix in 1–2 tablespoons heavy cream until the frosting reaches a light, spreadable consistency.
09 - Once cookies have cooled completely, frost generously with the vanilla frosting. Optionally dust with additional powdered sweetener or keto-friendly sprinkles before serving.
