Ingredients
- 1 cup natural unsweetened peanut butter (no added sugar)
- 1/2 cup vanilla whey protein powder (no added sugar)
- 1/3 cup powdered erythritol (or monk fruit sweetener)
- 1/4 cup blanched almond flour
- 2 tbsp coconut flour
- 2 tbsp unsalted butter, softened
- 1 tsp vanilla extract
- 1/4 tsp fine sea salt
- 1/4 cup sugar-free dark chocolate chips (optional)
Instructions
- 1
In a large bowl, stir together the peanut butter, softened butter, and vanilla extract until smooth and well combined.
- 2
Add the protein powder, powdered erythritol, almond flour, coconut flour, and sea salt. Mix until a thick, uniform dough forms.
- 3
If the dough feels too sticky, add 1 more tablespoon of coconut flour; if it's too dry, add 1 teaspoon of water. Fold in the chocolate chips if using.
- 4
Scoop the dough into 12 equal portions (about 1 heaping tablespoon each) and roll each into a smooth ball between your palms.
- 5
Arrange the balls on a parchment-lined tray and chill in the refrigerator for at least 30 minutes to firm up before serving.
Tips & notes
- Store in an airtight container in the fridge for up to 1 week, or freeze for up to 2 months.
- Use a creamy, drippy natural peanut butter for the best texture; overly stiff peanut butter can make the dough crumbly.
- Swap whey for a plant-based vanilla protein and use ghee instead of butter to make these dairy-free.
