Preheat oven: Set oven to 350°F and line a baking sheet with parchment paper.
Mix PBfit base: In a large bowl, combine 4 tablespoons of PBfit powder with water until smooth.
Combine ingredients: Add the remaining PBfit powder, almond flour, baking soda, honey, vanilla, and egg. Mix with a hand or stand mixer until a sticky dough forms.
Shape dough: Scoop about 1 tablespoon of dough for each cookie. Roll into balls and place on prepared sheet.
Flatten & pattern: Gently press each ball into a 2-inch round, about ¼-inch thick. Use a fork to create a crisscross pattern on top.
Bake: Bake 7–9 minutes until golden on the edges but still soft in the center.
Cool: Let cookies rest on the baking sheet 5–10 minutes before transferring to a wire rack.
