Before we start baking, it’s important to gather a few essential tools:
- Mixing Bowls – For combining your ingredients.
- Measuring Cups and Spoons – Precision is key for baking success.

Soft and Chewy Peanut Butter Oatmeal White Chocolate Cookies Cooking Guide
Now that we have everything ready, let’s get started with these Soft and Chewy Peanut Butter Oatmeal White Chocolate Cookies.
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). This ensures that your cookies bake evenly.
Step 2: Prepare Your Baking Sheet
Line a baking sheet with parchment paper. This keeps your cookies from sticking and makes cleanup a breeze.
Step 3: Cream the Butters and Sugars
In a large mixing bowl, combine the unsalted butter and creamy peanut butter. Using a whisk or electric mixer, beat them together until smooth and creamy. Gradually add in the light brown sugar and granulated sugar, mixing until well combined and fluffy.
Step 4: Add the Eggs and Vanilla
Beat in the egg, egg yolk, and vanilla extract until fully incorporated.
Step 5: Combine Dry Ingredients
In a separate bowl, whisk together the all-purpose flour, old-fashioned oats, and baking soda. Gradually add this mixture to the wet ingredients, stirring until just combined.
Step 6: Fold in the Chips
Gently fold in the white chocolate chips and peanut butter chips (or your choice of mix-ins) until evenly distributed throughout the dough.
Step 7: Scoop the Cookies
Using a cookie scoop or tablespoon, drop rounded balls of dough onto the prepared baking sheet, leaving space between each cookie to allow for spreading.
Step 8: Bake
Bake in the preheated oven for 10-12 minutes or until the edges are lightly golden. The centers may look soft, but they will firm up as they cool.
Step 9: Cool
Remove from the oven and let the cookies cool on the baking sheet for about 5 minutes before transferring them to a cooling rack to cool completely.
Dairy-Free/Gluten-Free Swaps
If you’re looking to make these cookies dairy-free or gluten-free, here are some easy swaps:
- Dairy-Free: Use dairy-free butter and ensure your chocolate chips are dairy-free.
- Gluten-Free: Substitute all-purpose flour with a gluten-free flour blend.
Insider Tips
- For a deeper flavor, try browning the butter before adding it to the mix.
- Chill the dough for 30 minutes before baking for thicker cookies.
- For extra chewiness, ensure you don’t overbake the cookies.
- Store cookies in an airtight container to keep them soft and fresh.
Leftovers & Meal Prep
These cookies are perfect for meal prep! Here’s how to store and enjoy your leftovers:
- Store baked cookies in an airtight container at room temperature for up to a week.
- For longer storage, freeze the baked cookies in a freezer-safe container for up to three months.
- You can also freeze the cookie dough. Scoop into balls and freeze on a baking sheet. Once solid, transfer to a freezer bag and bake from frozen, adding a couple of extra minutes to the baking time.
Your Top Questions
Can I use crunchy peanut butter instead of creamy?
Absolutely! Crunchy peanut butter will add extra texture to the cookies, making them even more delightful.
How do I prevent my cookies from spreading too much?
Make sure your butter is at the right temperature (softened, not melted) and chill the dough before baking if necessary. This helps the cookies maintain their shape.
What can I substitute for white chocolate chips?
You can use dark chocolate chips, butterscotch chips, or even dried fruits like raisins for a different flavor profile.
How do I know when the cookies are done baking?
Look for lightly golden edges and a soft center. They will continue to firm up as they cool on the baking sheet.
