📋 Ingredients

1 cup quick oats (not whole rolled oats)
½ teaspoon baking soda
¼ teaspoon salt
Optional add-ins: ½ cup chocolate chips or chopped peanuts

🍪 Instructions

Preheat oven to 350°F (175°C). Line a baking sheet with parchment paper.
Mix wet ingredients: In a bowl, stir together peanut butter, brown sugar, egg, and vanilla until smooth.
Add dry ingredients: Add oats, baking soda, and salt. Stir until fully combined. Fold in chocolate chips if using.
Shape cookies: Scoop about 1 tablespoon of dough and roll into balls. Place on baking sheet and gently press them down with your fingertips.
Bake: Bake 8–10 minutes, until the edges look slightly set but the centers are still soft.
Cool: Let cookies cool on the baking sheet for 5 minutes before transferring to a wire rack.
(They firm up while cooling, don’t overbake!)

💡 Tips & Variations

For thicker cookies, chill the dough for 15 minutes before baking.
Use chunky peanut butter for extra texture.
Add 1 tablespoon honey for natural sweetness and shine.
