These Healthy Peanut Butter Cookies are soft, chewy, and packed with wholesome ingredients like oats and natural peanut butter. Made without flour or butter and sweetened with just a touch of brown sugar, they’re a guilt-free treat that doesn’t sacrifice flavor.

Ingredients
- 2 large eggs
- ½ cup packed light brown sugar
- 1 tsp baking soda
- ¼ tsp fine sea salt
- 1 tsp vanilla extract
- 1 cup natural creamy peanut butter
- 1 cup old-fashioned oats
- Optional: ½ cup semisweet chocolate chips or chopped nuts
- Flaky sea salt, for topping
Instructions
- Prep the Oven and Baking Sheet:
Preheat the oven to 350°F (180°C). Line a large baking sheet with parchment paper and set aside. - Mix the Dough:
In a large mixing bowl, whisk together the eggs and brown sugar until smooth. Sprinkle the baking soda and sea salt over the mixture, then stir to combine. Add the vanilla extract and peanut butter, mixing until fully incorporated. Stir in the oats and, if using, fold in chocolate chips or chopped nuts. - Scoop the Dough:
Use a medium (2-tablespoon) cookie scoop or spoon to portion out dough balls onto the prepared baking sheet. Lightly press down the tops of each cookie, as they won’t spread much during baking. - Bake:
Bake for 10 minutes, or until the edges are just set. Remove from the oven, sprinkle each cookie with a pinch of flaky sea salt, and let them cool on the pan for at least 5 minutes before serving. - Serve:
Enjoy warm, or let cool completely and store for later.
