Preheat and prep: Heat your oven to 350°F (175°C). Line a baking sheet with parchment paper or a silicone baking mat.
Warm the almond butter: If your almond butter is stiff, microwave it for 10–15 seconds to make mixing easier.
Mix the wet ingredients: In a medium bowl, whisk together the almond butter, egg, melted butter (or coconut oil), and vanilla until smooth.
Add the dry ingredients: Stir in the granulated keto sweetener, almond flour, baking powder, and salt. Mix until a thick dough forms.
If using chocolate chips or nuts, fold them in now.
Adjust texture if needed: Dough should be thick but scoopable. If it’s too sticky, add 1–2 teaspoons more almond flour. If too dry, add 1 teaspoon almond milk or water.
Portion the cookies: Scoop 1–1.5 tablespoon portions onto the baking sheet, spacing them about 2 inches apart.
Lightly flatten each mound with your fingertips or the bottom of a glass.
Optional crosshatch: For a classic look, press a fork in a crisscross pattern on each cookie. This also helps them bake evenly.
Bake: Bake for 9–12 minutes, until the edges are set and lightly golden. The centers will still look soft—that’s good.
Cool completely: Let cookies rest on the baking sheet for 10 minutes, then transfer to a rack to cool fully.
They firm up as they cool.
Enjoy: Serve once cooled to your preferred texture. They’re great warm and even better after they set.
