The result is a batch of soft, chewy peanut butter cookies that are perfectly sweet, slightly salty, and packed with texture in every bite. Whether you’re baking for a family treat or craving something indulgent, these peanut butter cookies are guaranteed to impress.
Method
Preheat Your Oven
Start by setting your oven to 350°F (180°C) so it reaches the right temperature by the time your cookie dough is ready. Line your baking sheet with parchment paper or a silicone baking mat to prevent the cookies from sticking and to ensure an even bake.
Mix the Wet Ingredients
In a large mixing bowl, add the room temperature butter and peanut butter. Using a hand mixer or whisk, blend them together until smooth and creamy. This step ensures that the fats are well combined and will create the perfect cookie texture. Next, add the egg, white sugar, and brown sugar. Beat the mixture until everything is well incorporated, resulting in a fluffy and light batter. The sugars not only add sweetness but also contribute to the chewy texture of the cookies.
Prepare the Dry Ingredients
In a separate bowl, combine the flour and baking soda. Whisk them together to evenly distribute the baking soda throughout the flour. This helps the cookies rise properly during baking and ensures a balanced texture. Preparing the dry ingredients separately prevents clumps and guarantees a smooth dough when added to the wet mixture.
Combine the Dry and Wet Ingredients
Gradually add the dry ingredient mixture into the bowl of wet ingredients. Stir gently using a rubber spatula or a wooden spoon, incorporating the flour mixture little by little. Be careful not to overmix at this stage, as doing so can develop too much gluten, resulting in dense and tough cookies. Stop mixing as soon as you see the flour is fully incorporated and a soft dough has formed.
Fold in the Mix-Ins
Now it’s time to add the star ingredients that make these cookies extra special. Gently fold in the chopped graham crackers and chocolate chunks. Use a spatula to evenly distribute them throughout the dough, ensuring every bite has the perfect mix of crunch and chocolatey goodness. Again, avoid overmixing; just stir enough to incorporate them.
Add the Marshmallow Fluff
This step is crucial for achieving that signature gooey, s’mores-like effect. Add the marshmallow fluff into the dough and fold it in gently. The key here is to mix just enough to create streaks of marshmallow throughout the dough rather than blending it in completely. This ensures pockets of marshmallow remain intact, giving the cookies that irresistible, melted texture when baked.
Scoop and Bake
Using a cookie scoop or two tablespoons, scoop out portions of dough and place them onto the prepared baking sheet. Make sure to leave ample space between each dough ball, as these cookies spread quite a bit while baking. If the dough seems sticky, chilling it in the refrigerator for 10–15 minutes can make it easier to handle.
Bake
Place the baking sheet into the preheated oven and bake for 10 minutes. The cookies should look slightly underdone in the center when you take them out, but this is exactly what you want! They will continue to set as they cool on the baking sheet, resulting in soft, chewy cookies with crispy edges and a gooey center.
Cool and Enjoy
Allow the cookies to cool on the baking sheet for about 5 minutes before transferring them to a wire rack. This helps them firm up slightly while keeping their chewy texture. Once cooled, they’re ready to be devoured! Enjoy them warm for the ultimate gooey experience or store them in an airtight container for later.

minutesIngredients
1/2 cup butter (room temperature)
1/3 cup peanut butter
1 egg
1/2 cup white sugar
1/2 cup brown sugar
1 cup + 2 tbsp all-purpose flour
1 tsp baking soda
1/3 cup chopped graham crackers
1/3 cup chocolate chunks
1/4 cup marshmallow fluff
Directions
- Preheat Your Oven – Set your oven to 350°F (180°C) and line your baking sheet with parchment paper.
- Mix the Wet Ingredients – In a large bowl, beat together the room temperature butter and peanut butter until smooth. Add the egg, white sugar, and brown sugar, mixing until everything is well combined.
- Prepare the Dry Ingredients – In a separate bowl, mix the flour and baking soda.
- Combine – Gradually add the dry ingredients to the wet mixture, stirring gently to form a dough.
- Fold in the Mix-Ins – Gently fold in the chopped graham crackers and chocolate chunks. Be careful not to overmix!
- Add the Marshmallow Fluff – This step is crucial! Lightly fold in the marshmallow fluff at the very end. The goal is to keep streaks of fluff visible for that gooey texture, so don’t overmix.
- Scoop and Bake – Using a cookie scoop or two tablespoons, place dough balls onto the baking sheet, leaving space between them because they will spread.
- Bake – Place in the oven and bake for 10 minutes or until the edges look set and slightly golden.
- Cool and Enjoy – Let the cookies cool on the baking sheet for a few minutes before transferring them to a wire rack. Enjoy warm or at room temperature!
Notes
- Room Temperature Butter – Using cold butter will make it hard to mix, and melted butter will cause the cookies to spread too much.
- Do Not Overmix – Especially when adding marshmallow fluff! Overmixing will make it disappear into the dough instead of creating delicious gooey pockets.
- Spacing is Key – These cookies spread a lot while baking, so give them enough room on the baking sheet.
- Watch the Bake Time – They may look slightly underdone when you take them out, but they will continue to set as they cool.
Serving Suggestions
- Enjoy these cookies warm with a glass of cold milk.
- Make an indulgent ice cream sandwich by placing a scoop of vanilla ice cream between two cookies.
- Drizzle with melted chocolate for extra decadence.
- Pack them in lunchboxes for a sweet surprise.
