Ingredients

• 1.5 cups / 150g ground walnuts
• 2 tbsp / 24g granulated erythritol
• 1 tsp / 3g ground cinnamon
• 1 large egg

Instructions

1. Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
2. In a medium bowl, whisk together the egg, granulated erythritol, and ground cinnamon until fully combined.
3. Fold in the ground walnuts until a thick, sticky dough forms.
4. Scoop tablespoon-sized portions of dough, roll into balls, and place them about an inch apart on the prepared baking sheet.
5. Bake for 10-13 minutes, or until the edges are lightly golden. Let the cookies cool on the sheet for 5 minutes before transferring to a wire rack to cool completely.

Pro Tips

• For a deeper, richer flavor, toast the walnuts in a dry skillet for 3-5 minutes before grinding. Be sure to let them cool completely first.
• Add a splash of vanilla extract (about 1/2 tsp) to the egg mixture for an extra layer of flavor.
• Don’t overbake! These cookies are best when slightly soft in the center. They will firm up as they cool, so pull them from the oven as soon as the edges are set.

FAQ

Q: Are these keto walnut cookies soft or crunchy
A: These cookies have a satisfyingly crisp and golden edge with a slightly softer center. They firm up as they cool, so for the best texture, pull them from the oven as soon as the edges are set.

Q: Can I use a different nut instead of walnuts
A: This recipe is specifically designed for the rich flavor of walnuts. While you could experiment with other ground nuts like pecans or almonds, the taste, texture, and nutritional information will change.

Q: How should I store these cookies
A: To maintain their freshness, store the cooled keto walnut cookies in an airtight container at room temperature for up to 5 days.
