Preheat your oven to a comfortable 350°F (175°C). Grab a baking sheet and line it with parchment paper or a silicone mat – this prevents sticking and makes cleanup a breeze! You might need two sheets for all 16 cookies.
In a large mixing bowl, combine the almond flour, coconut flour, sugar-free sweetener, baking powder, ground cinnamon, and kosher salt. Give it a good whisk until everything is evenly blended.
Pour the melted butter, crack in the two large eggs, and add the vanilla extract to your dry mixture. Stir everything together until a thick, uniform dough forms.
Gently fold in the sliced almonds and shelled hemp hearts. Mix just enough so they are evenly distributed throughout the cookie dough, adding that perfect texture.
Scoop out the dough into 16 even-sized portions (a small cookie scoop works great!). Place them on your prepared baking sheets, leaving about 2 inches between each cookie. Use your fingers to gently flatten the tops of each cookie slightly.
Pop the baking sheets into your preheated oven and bake for 12-13 minutes. Keep an eye on them until the bottom edges turn a lovely golden brown.
Once baked, remove the cookies from the oven and let them cool completely on the baking sheet. This allows them to firm up perfectly.
