Essential Ingredients
Here’s what you’ll need to make this delicious dish:
-
Old-Fashioned Oats: Choose rolled oats for a chewy texture; they hold up beautifully during baking.
-
Peanut Butter: Use creamy or chunky based on your preference for texture; both work equally well.
-
Brown Sugar: Opt for light brown sugar for a subtle caramel flavor that enhances sweetness.
-
All-Purpose Flour: Use standard flour to give structure to your cookies; it helps bind everything together.
-
Baking Soda: This little hero makes your cookies rise and gives them that soft, chewy texture we all love.
-
Eggs: One large egg adds moisture and helps bind ingredients; be sure it’s at room temperature for best results.
-
Salt: A pinch of salt balances the sweetness and enhances the overall flavor of your cookies.
-
Vanilla Extract: A splash of vanilla adds depth to your cookie dough; it’s like adding a warm hug in flavor form.

Let’s Make it Together
Preheat your oven to 350°F (175°C), ensuring it’s hot enough to create that lovely golden crust we’re seeking.
Mixing It Up: In a large mixing bowl, combine 1 cup of peanut butter with 1 cup of brown sugar until smooth. The mixture should be creamy and smell heavenly already.
Add Wet Ingredients: Beat in one egg and 1 teaspoon of vanilla extract until fully incorporated. The batter should look glossy and inviting at this point.
Combine Dry Ingredients: In another bowl, whisk together 1 cup of flour, 1 teaspoon of baking soda, and a pinch of salt. This step keeps our dry ingredients evenly distributed throughout the dough.
Fold It All Together: Gradually mix the dry ingredients into your wet mixture until just combined. Be gentle here! Overmixing can lead to tough cookies – we want them soft and chewy.
Add Oats**: Stir in 1 cup of old-fashioned oats until evenly mixed throughout the dough. The oats should provide a lovely texture contrast against the creaminess of the peanut butter.
Bake Those Cookies**: Spoon tablespoon-sized portions onto a lined baking sheet about two inches apart. Bake for 10-12 minutes or until they turn golden brown around the edges but still soft in the center.
Once baked, allow them to cool on a wire rack before indulging—if you can resist!
Enjoy these peanut butter oatmeal cookies with a glass of cold milk or share them with friends; either way, prepare for smiles all around!
