Choose natural peanut butter made only from peanuts and salt to keep carbs low and avoid added sugars that can stall ketosis. If your peanut butter is on the runny side, add a bit more almond flour, a tablespoon at a time, until the mixture holds its shape when rolled. For firmer, more truffle-like bites, store them in the freezer and let them sit at room temperature for a few minutes before eating. You can swap almond flour for finely ground peanut flour or coconut flour, but if using coconut flour start with a much smaller amount because it absorbs more moisture and adjust gradually. To change up the flavor, fold in a few chopped roasted peanuts, a pinch of cinnamon, or a drop of liquid stevia for extra sweetness without affecting the carb count. These are very satisfying, so keep portions small to stay within your daily macros.
