Preheat your oven to 325°F (163°C).

In a mixing bowl, combine almond flour, erythritol, salt, and baking soda.

Add peanut butter and milk; stir until a dough forms.

Roll the dough into 1-inch balls and flatten them on a baking sheet lined with parchment paper.

Bake for about 10 minutes until edges are set but centers remain soft.

Allow cooling completely before serving.
