Must-Have Equipment

Peanut Butter Lovers Monster Cookies: Step-by-Step Guide

Ready to bake? Follow these simple steps to make your very own Peanut Butter Lovers Monster Cookies.
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). This step is crucial as it ensures that your cookies bake evenly.
Step 2: Cream the Butter and Sugars
In a large mixing bowl, combine the unsalted butter, light brown sugar, and creamy peanut butter. Using an electric mixer, beat them together until the mixture is light and fluffy, about 2-3 minutes.
Step 3: Add Egg and Vanilla
Add in the egg and vanilla extract. Mix until combined, scraping down the sides of the bowl as necessary to ensure everything is well incorporated.
Step 4: Combine Dry Ingredients
In a separate bowl, whisk together the all-purpose flour, baking soda, baking powder, cornstarch, and salt. This step helps to evenly distribute the leavening agents throughout the flour.
Step 5: Combine Wet and Dry Mixtures
Gradually add the dry mixture to the wet mixture, stirring until just combined. Be careful not to overmix, as this can lead to tough cookies.
Step 6: Fold in Oats and Chips
Gently fold in the old-fashioned oats, semisweet chocolate chips, peanut butter chips, and Reese’s Pieces candies. The dough will be thick and chunky.
Step 7: Scoop the Cookies
Using a cookie scoop, drop generous portions of dough onto a baking sheet lined with parchment paper. Leave enough space between each cookie, as they will spread while baking.
Step 8: Bake
Place the baking sheet in the preheated oven and bake for 10-12 minutes, or until the edges are lightly golden. The centers may look a bit soft, but they will continue to set as they cool.
Step 9: Cool and Enjoy
Once baked, remove the cookies from the oven and let them cool on the baking sheet for about 5 minutes before transferring them to a wire rack to cool completely. Enjoy your Peanut Butter Lovers Monster Cookies with a glass of milk or your favorite cup of coffee!
Make It Fit Your Plan

Looking to customize your Peanut Butter Lovers Monster Cookies? Here are some ideas:
- Nut-Free Version: Substitute sunflower seed butter for peanut butter to create a nut-free cookie.
- Gluten-Free Option: Use a gluten-free all-purpose flour blend in place of regular flour.
- Extra Crunch: Add chopped nuts like walnuts or pecans for added texture and flavor.
- Healthier Twist: Reduce the sugar by using a sugar substitute or adding more oats for a heartier cookie.
Avoid These Traps
Baking can sometimes lead to unexpected results if you’re not careful. Here are a few traps to avoid:
- Overmixing the Dough: This can lead to tough cookies. Mix just until combined.
- Not Measuring Ingredients Accurately: Baking is a science; using the wrong measurements can alter the outcome.
- Skipping the Chilling Step: If your dough feels too soft, chill it for 30 minutes before baking to help the cookies hold their shape.
Keep-It-Fresh Plan
To keep your Peanut Butter Lovers Monster Cookies fresh and delicious, follow these tips:
- Storage: Store cookies in an airtight container at room temperature for up to a week.
- Freezing: Freeze unbaked dough balls by placing them on a baking sheet and freezing until solid. Then transfer to a zip-top bag for up to 3 months. Bake straight from the freezer, adding an extra minute or two to the baking time.
- Reheating: If you want to enjoy them warm, pop them in the microwave for a few seconds to bring back that fresh-baked goodness.
Your Top Questions
Can I use natural peanut butter instead of creamy peanut butter?
Yes, you can use natural peanut butter, but be aware that it may alter the texture slightly. Natural peanut butter often contains less sugar and may be a bit runnier, affecting the overall consistency of the dough.
What can I substitute for brown sugar?
If you don’t have brown sugar on hand, you can use white granulated sugar mixed with a little molasses for a similar flavor and moisture. For every cup of brown sugar, use 1 cup of granulated sugar plus 1 tablespoon of molasses.
How can I make these cookies more chocolatey?
For an extra chocolatey flavor, consider adding cocoa powder to the dry ingredients or using chocolate chunk pieces instead of chips. You can never go wrong with more chocolate!
Can I make these cookies vegan?
Yes! To make these cookies vegan, substitute the egg with a flax egg (1 tablespoon ground flaxseed mixed with 2.5 tablespoons water) and use a vegan butter alternative.
