Malted Peanut Butter Oatmeal Cookies Ingredients
For the Dough
• Unsalted Butter – Provides richness and moisture to the dough. Use salted butter and reduce additional salt if necessary.
• Creamy Peanut Butter – Adds intense peanut flavor and creaminess. Crunchy peanut butter can substitute for texture.
• Light Brown Sugar – Contributes sweetness and moisture while enhancing the cookie’s flavor profile. Dark brown sugar can also be used for a deeper flavor.
• Granulated White Sugar – Balances sweetness and contributes to the cookie’s structure.
• Egg – Binds the ingredients together and helps with leavening.
• Vanilla Extract – Adds aromatic flavor; essential for depth in taste.
• All-Purpose Flour – Provides structure. Gluten-free flour can be substituted, but the texture may change.
• Old-Fashioned Oats – Adds chewiness and texture. Quick oats are a suitable substitute, although the texture will differ slightly.
For the Magic Touch
• Malted Milk Powder – Enhances the peanut flavor and reduces sweetness. Do not substitute with diastatic malt powder for best results.
• Baking Soda – Acts as a leavening agent to provide rise.
• Salt – Balances flavor. Adjust based on the saltiness of butter used.
Step‑by‑Step Instructions for Malted Peanut Butter Oatmeal Cookies
Step 1: Prep Oats
Start by preheating your food processor. Add old-fashioned oats and pulse until you achieve a mixture of finely ground and whole oats, about 20-25 seconds. This will create the perfect texture for your Malted Peanut Butter Oatmeal Cookies, enhancing their chewy quality.
Step 2: Mix Dry Ingredients
In a medium mixing bowl, whisk together all-purpose flour, the pulsed oats, malted milk powder, baking soda, and salt. Ensure everything is evenly distributed. This dry mixture will provide structure and flavor to your cookies, setting them up for delightful results.
Step 3: Cream Butter and Sugars
In a stand mixer bowl, combine the unsalted butter and creamy peanut butter with the light brown sugar and granulated sugar. Beat on medium speed for 3-5 minutes, or until the mixture is light and fluffy. This process incorporates air into your dough, ensuring your cookies bake to chewy perfection.
Step 4: Incorporate Wet Ingredients
Add the egg and vanilla extract to the butter and sugar mixture, mixing on low speed until fully combined. The wet ingredients will enrich the texture of your Malted Peanut Butter Oatmeal Cookies, ensuring a rich peanut flavor and a chewy center in every bite.
Step 5: Blend Dry into Wet
Gradually add the dry ingredient mixture to the wet mixture in your stand mixer on low speed. Continue mixing until just combined, about 1-2 minutes. The dough will be soft and slightly sticky, which is perfect. For optimum flavor, refrigerate the dough for at least two hours, ideally overnight.
Step 6: Preheat Oven
After chilling the dough, preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper to prevent sticking. Using a #50 cookie scoop, portion out the dough, placing each mound two inches apart on the prepared baking sheet. This spacing ensures your Malted Peanut Butter Oatmeal Cookies bake evenly.
Step 7: Bake
Place the cookie sheet in the preheated oven and bake for 9-11 minutes. Keep an eye on them—you’re looking for slightly browned edges and moist centers that show a bit of wetness in cracks. This visual cue will help ensure your cookies have that perfect chewy center.
Step 8: Cool
Once baked, remove the cookies from the oven and let them cool on the baking sheet for about 5 minutes. After cooling slightly, carefully transfer them to a wire rack to cool completely. This step ensures your Malted Peanut Butter Oatmeal Cookies maintain their delightful texture and don’t become soggy.

To maintain quality, be sure to wrap the dough tightly in plastic wrap before chilling, which prevents it from drying out. When you’re ready to bake, simply scoop the dough onto a prepared baking sheet and bake as instructed.

Expert Tips for Malted Peanut Butter Oatmeal Cookies

Malted Peanut Butter Oatmeal Cookies Recipe FAQs
What type of oats should I use for this recipe?
For the best texture, I recommend using old-fashioned oats. They provide that wonderful chewiness. However, if you’re short on time, quick oats can be used as an alternative; just keep in mind that the texture may be slightly different.
How should I store leftover cookies?
To keep your Malted Peanut Butter Oatmeal Cookies fresh, store them in an airtight container at room temperature for up to one week. If you’d like to prolong their freshness, you can refrigerate them for up to two weeks, ensuring they stay moist and chewy.
Can I freeze these cookies?
Absolutely! To freeze your Malted Peanut Butter Oatmeal Cookies, place them in an airtight container or a freezer bag, and they will last for up to three months. To enjoy them later, simply thaw them at room temperature or pop them in the microwave for about 10-15 seconds to warm them up.
What are some common issues when baking these cookies?
If your cookies turn out too dry, it might be due to overmixing the dough or using too much flour. Make sure to spoon the flour into the measuring cup rather than scooping directly from the bag for an accurate measurement. Keep an eye on baking time too; slightly underbaked cookies will stay chewy and soft!
Are there any dietary considerations?
While the recipe is nut-friendly for those without allergies, remember that it contains peanut butter, which is not safe for individuals with peanut allergies. If you’re looking to make this recipe more inclusive, you could try a sunbutter alternative; just be sure to check if anyone in your household is allergic to sunflower seeds.
How can I enhance the flavor of my cookies?
For an even richer malt flavor, you can increase the amount of malted milk powder by a tablespoon. Additionally, consider adding in some chocolate chips or butterscotch chips for a sweet twist—this way, every bite is packed with flavor!
