Oatmeal Peanut Butter Cookies Ingredients

½×1×2×3×4×5×6×7×8×9×10×

ⓘ Original recipe (1×) yields 18–22 cookies (depending on scoop size)

• 1 cup (240 g) creamy peanut butter
• 1/2 cup (115 g) unsalted butter, softened?
• 1 cup (200 g) packed light brown sugar
• 1/2 cup (100 g) granulated sugar
• 2 large eggs, room temperature?
• 1 teaspoon pure vanilla extract
• 1 1/4 cups (150 g) old-fashioned rolled oats
• 1 cup (125 g) all-purpose flour
• 1 teaspoon baking soda
• 1/2 teaspoon fine sea salt
• 1/2 cup (90 g) semisweet chocolate chips or chopped dark chocolate (optional)
• 2 tablespoons (20 g) chopped roasted peanuts (optional, for crunch)

Instructions

1. Preheat the oven to 350°F (175°C). Line two baking sheets with parchment paper or lightly grease them.
2. In a large bowl, cream the softened butter and both sugars until light and fluffy, about 2–3 minutes with a hand mixer or 4–5 minutes by hand.
3. Add the peanut butter and beat until smooth and combined, scraping the bowl as needed.
4. Beat in the eggs one at a time, then add the vanilla and mix until incorporated.
5. In a separate bowl, whisk together the flour, rolled oats, baking soda, and salt.
6. Gradually fold the dry ingredients into the wet mixture using a spatula until just combined. Stir in chocolate chips and chopped peanuts if using.
7. Scoop dough by tablespoonfuls (about 1 1/2 tablespoons per cookie) and place on the prepared baking sheets about 2 inches apart. For uniform cookies, use a small cookie scoop.
8. Optional: gently flatten each dough ball with the back of a fork or your palm for a more even bake; they will spread slightly on their own.
9. Bake for 9–12 minutes, rotating the pan halfway through. The cookies are done when the edges are set and the centers still look slightly soft; they will firm as they cool.
10. Cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely. Store as noted below.

Substitutions

• Peanut butter: Use natural peanut butter (stirred) for a more pronounced peanut flavor and a slightly softer texture, or swap in sunflower seed butter to make the recipe nut-free.
• Flour: Replace up to half the all-purpose flour with whole wheat pastry flour for a nuttier flavor; if the dough seems dry, add 1 tablespoon of milk.
• Sugar: Swap granulated sugar for coconut sugar 1:1, and use light brown sugar alternatives if needed; expect a slight color and flavor change.
• Chocolate: Use dried cherries or raisins instead of chocolate chips for a fruitier cookie.

Storage and Reheating

• Room temperature: Store cooled cookies in an airtight container at room temperature for up to 4 days.
• Refrigeration: To extend freshness up to 10 days, refrigerate in an airtight container—peanut butter can firm up when cold.
• Freezing: Freeze baked cookies in a single layer on a tray until firm, then transfer to a freezer-safe bag or container for up to 3 months. Thaw at room temperature or warm briefly in a 300°F (150°C) oven for 5–7 minutes.
• Reheating: For a fresh-from-the-oven texture, microwave a cookie for 10–12 seconds or warm in a 300°F (150°C) oven for 4–6 minutes.

FAQs

• Can I make these gluten-free? Yes—use a 1:1 gluten-free baking flour and ensure your oats are certified gluten-free.
• Why are my cookies flat? Over-softened butter or too much liquid can cause flattening; therefore, chill the dough 15–20 minutes before baking if needed.
• Can I make the dough ahead? Yes—refrigerate the dough for up to 48 hours or freeze portions for up to 3 months; bake straight from chilled or partially thawed dough (add 1–2 minutes to bake time).

These Oatmeal Peanut Butter Cookies strike a balance between hearty oats and rich peanut butter without complicated steps. They’re ideal for school lunches, a quick dessert, or a weekend bake-off.
