Ingredients Needed

Here’s everything you’ll need to make these delicious peanut butter oatmeal cookies.

Each ingredient plays a key role in delivering the perfect texture and flavor:

Ingredients

• 1/2 cup unsalted butter (112 grams), softened
• 1/2 cup packed brown sugar (100 grams)
• 1/3 cup granulated sugar (66 grams)
• 1/2 cup peanut butter (120 grams)
• 1 large egg
• 1 tsp vanilla extract
• 3/4 cup all-purpose flour (94 grams)
• 3/4 tsp baking soda
• 1/4 tsp salt
• 3/4 cup quick oats
• 1/2 cup old-fashioned oats

Step-by-Step Instructions

Follow these simple steps to bake a batch of soft and chewy peanut butter oatmeal cookies:

Step 1: Preparation

• Preheat the Oven: Set your oven to 350°F (175°C). This temperature is ideal for baking cookies that are golden on the edges and soft in the middle.
• Prepare the Baking Sheets: Line your baking sheets with parchment paper or silicone mats. This prevents the cookies from sticking and makes cleanup easier.

Step 2: Mixing the Dough

• Cream the Butter and Sugars: In a large mixing bowl, cream together the softened butter, peanut butter, brown sugar, and granulated sugar. Mix until the texture is smooth and creamy. This step helps incorporate air into the mixture, ensuring soft cookies.
• Add the Eggs and Vanilla: Beat in the egg and vanilla extract until fully combined. This adds moisture and flavor to the dough, ensuring it bakes evenly.
• Combine Dry Ingredients: In a separate bowl, whisk together the all-purpose flour, baking soda, and salt. Gradually add this dry mixture to the wet ingredients, mixing until just combined. Be careful not to overmix, as this can make the cookies tough.
• Incorporate the Oats: Stir in the quick oats and old-fashioned oats until evenly distributed. This combination of oats gives the cookies their perfect chewy texture.

Step 3: Shaping and Baking

• Shape the Dough: Use a cookie scoop or tablespoon to portion out the dough. Roll into balls about 1 to 1.5 tablespoons in size and place them on the prepared baking sheets. Space the dough balls about 2 inches apart to allow for spreading during baking.
• Bake: Bake one tray at a time on the middle rack of your preheated oven for 10–12 minutes. The cookies are ready when the edges turn golden brown, but the centers still look slightly underbaked. They will continue to set as they cool.
• Cool the Cookies: Remove the baking sheet from the oven and let the cookies cool for 5 minutes. This helps them firm up. Transfer the cookies to a wire rack to cool completely.

Tips for Success

Peanut Butter Selection

For the best results, stick to commercially prepared smooth peanut butter.

These types of peanut butter are consistent in texture and blend easily with the other ingredients.

Avoid natural or homemade peanut butter, as the oil separation can lead to uneven dough and affect the final texture of the cookies.

Oat Variations

This recipe uses a mix of quick oats and old-fashioned oats for the perfect balance of chewiness and structure.

If you only have one type on hand, you can use just quick oats for a smoother texture or old-fashioned oats for a heartier bite.

However, do not use instant oats.

Instant oats act more like flour and can make the cookies dense and dry.

Dough Chilling

One of the advantages of this recipe is that the dough doesn’t require chilling, making it quick and convenient.

However, if you prefer thicker cookies, chilling the dough for 30 minutes to 1 hour before baking can help reduce spreading.

You can also chill the dough for up to 48 hours if you want to bake them later or freeze the dough for long-term storage.

Variations and Add-Ins

This recipe is versatile and easily customizable to suit your taste preferences.

Here are some creative add-ins to take your peanut butter oatmeal cookies to the next level:

Chocolate Chips

For a touch of sweetness, fold in semisweet or dark chocolate chips.

They melt slightly during baking, adding bursts of rich chocolate flavor to each bite.

Use about 1 to 1.5 cups of chocolate chips for the perfect balance without overwhelming the cookie’s texture.

Nuts

If you enjoy a little crunch, consider adding chopped nuts.

Walnuts and pecans work especially well with the nutty flavor of peanut butter.

Add up to 1 cup of chopped nuts to the dough for a satisfying texture and extra richness.

Dried Fruits

Incorporating dried fruits like raisins or dried cranberries is an excellent way to introduce a chewy element and subtle sweetness.

These pair beautifully with the hearty oats and nutty base.

Use about 3/4 to 1 cup of dried fruit for a balanced flavor without overpowering the other ingredients.

Dietary Considerations

Gluten-Free Option

To make the recipe gluten-free, use certified gluten-free oats.

Regular oats may contain traces of gluten due to processing, so it’s essential to choose oats labeled gluten-free for those with dietary restrictions.

Replace the all-purpose flour with a gluten-free flour blend designed for baking.

Ensure the blend includes a binding agent like xanthan gum for the best results.

Dairy-Free Adaptation

For a dairy-free version, swap out the butter with an equal amount of coconut oil or a dairy-free butter alternative.

Coconut oil adds a subtle flavor and maintains the cookie’s soft and chewy texture.

Ensure that the other ingredients, like peanut butter, do not contain any hidden dairy additives.

Storage and Shelf Life

Proper storage ensures your peanut butter oatmeal cookies stay fresh and delicious for as long as possible.

Here’s how to store them effectively.

Room Temperature

To keep the cookies fresh, store them in an airtight container at room temperature.

They’ll stay soft and flavorful for up to 5 days.

To maintain their chewy texture, consider placing a slice of bread in the container.

The bread helps retain moisture, keeping the cookies from drying out.

Freezing the Dough

If you want to prepare the dough in advance, freezing is an excellent option.

Roll the dough into balls, then arrange them on a baking sheet in a single layer.

Freeze the tray until the dough balls are firm, about 1-2 hours.

Once frozen, transfer them to a freezer-safe bag or container.

Label them with the date, and store them for up to 2 months.

When ready to bake, place the frozen dough balls directly onto a baking sheet and bake at 350°F for 13-16 minutes.

There’s no need to thaw the dough.

Freezing Baked Cookies

You can also freeze fully baked cookies for later enjoyment.

Allow the cookies to cool completely before freezing.

Place them in a single layer inside a freezer-safe bag or container, separating layers with parchment paper to prevent sticking.

Frozen cookies will keep well for up to 2 months.

To serve, let them thaw at room temperature for about 20-30 minutes.

Conclusion

Peanut butter oatmeal cookies are a simple, delicious treat that anyone can make.

With their perfect texture and rich flavor, they’re sure to become a favorite in your home.

FAQs

Can I use crunchy peanut butter?

Yes, you can use crunchy peanut butter in this recipe.

It will add bits of peanut pieces, creating a slightly different texture with more crunch in each bite.

Keep in mind that the overall consistency of the dough might be a bit firmer compared to using smooth peanut butter.

How do I prevent cookies from spreading too much?

To minimize spreading, you can chill the dough for about 30 minutes before baking.

This helps firm up the butter and slows the spread during baking.

Also, make sure your oven is properly preheated to 350°F (175°C).

An oven that’s too hot or too cold can affect how the cookies spread, so using an oven thermometer for accuracy can be helpful.
