Scale
Ingredients
- 1 1/2 cups creamy or chunky peanut butter (that’s one full 16-ounce jar minus 1/4 cup)
- 2 1/2 cups packed coconut sugar or 2 cups lightly packed brown sugar
- 1/3 cup melted coconut oil or 5 tablespoons melted butter
- 3 large eggs
- 2 teaspoons baking soda
- 2 teaspoons vanilla extract
- 2 1/2 cups quick-cooking oats or 2 3/4 cups old-fashioned oats (certified gluten-free if necessary)
- Optional: flaky sea salt, for sprinkling
Instructions
- Preheat the oven to 350 degrees Fahrenheit. Line tw0 large, rimmed baking sheets with parchment paper or silicone mats for easy clean-up.
- In a large mixing bowl, combine the peanut butter with the sugar and coconut oil. Use an electric mixer or a large spoon to mix until well combined. Add the eggs, baking soda and vanilla, and mix well. Add the oats and mix until they’re evenly incorporated.
- Drop 2 tablespoons of dough per cookie onto the prepared baking sheets. These cookies spread while baking, so leave a couple of inches around each one. Gently shape them into a more rounded mound and press down lightly so they’re no taller than 1 inch.
- Bake 8 to 10 minutes, until they’re just starting to turn golden around the edges. Do not overbake. They will flatten more as they cool. Let the cookies cool for 10 minutes before transferring them to a cooling rack. In the meantime, bake your next round of cookies, and so on.
- If desired, sprinkle the cookies lightly with flaky sea salt. Let them cool completely before storing them in an airtight container. Cookies will keep well for several days at room temperature.
Notes
Recipe adapted from my monster cookies recipe.
Make it gluten free: Be sure to use certified gluten-free oats.
Make it vegan/egg free: Commenters report that flax eggs work fairly well (you might need to press the cookies down into a cookie-like shape before baking, and they might need a couple more minutes in the oven). To make the recipe vegan, also use coconut oil instead of butter.
Make it dairy free: Use coconut oil instead of butter.
Make it nut free: Sunflower seed butter should work well. If you’re only avoiding peanuts, almond butter will work, too.
