About the Ingredients
Unsalted butter
Butter adds richness and helps create a tender cookie texture. Using unsalted butter allows you to control the overall salt level and balance the sweetness perfectly.
Creamy peanut butter
Peanut butter is the star of this recipe. It gives the cookies their signature flavor and soft texture. Stick with standard creamy peanut butter rather than natural styles for the best consistency.
Granulated sugar and brown sugar
This combination provides the best texture—granulated sugar helps the cookies hold their shape and develop lightly crisp edges, while brown sugar adds moisture and a subtle caramel-like depth.
Egg and vanilla extract
The egg binds the dough and gives structure, while vanilla extract enhances and rounds out the peanut butter flavor without overpowering it.
All-purpose flour, baking soda, and salt
Flour forms the structure of the cookies, baking soda gives a slight lift, and salt balances the sweetness while intensifying the peanut butter flavor.
Peanut butter filling
The filling is a creamy blend of peanut butter, butter, powdered sugar, vanilla, and milk. It’s smooth, rich, and slightly sweet—exactly what makes these sandwich cookies so iconic.
Tips & Tricks
Shape the dough carefully
Rolling the dough into small ovals instead of round balls gives the cookies that classic Nutter Butter look. Don’t worry if they’re not perfect—rustic is part of the charm.
Don’t overbake
Bake until the edges are just lightly golden. The cookies will continue to set as they cool, keeping the centers soft and tender.
Cool completely before filling
Make sure the cookies are fully cooled before adding the filling. Warm cookies can cause the filling to melt and slide.
Use a piping bag for neat filling
Piping the filling onto the cookies makes assembly quicker, cleaner, and more uniform.
Pro Tips
- If the dough feels too soft, chill it for 15–20 minutes before shaping.
- Lightly sugar the fork before pressing to prevent sticking.
- Be generous with the filling—these cookies are meant to be indulgent.
- Let assembled cookies rest for 20–30 minutes so the filling sets.
- Store cookies in a single layer or with parchment between layers to keep them neat.
Step-by-Step Instructions
Prepare the dough
Preheat the oven to 350°F (175°C) and line a baking sheet with parchment paper. In a large bowl, cream together the butter, peanut butter, granulated sugar, and brown sugar until light and fluffy. Add the egg and vanilla extract and mix until fully combined.
Add dry ingredients
In a separate bowl, whisk together the flour, baking soda, and salt. Gradually mix the dry ingredients into the wet ingredients until a soft dough forms.
Shape and bake
Roll the dough into 1-inch portions and gently shape them into ovals. Place on the baking sheet and press each cookie with a fork to create a crosshatch pattern. Bake for 8–10 minutes, then let cool completely.
Make the filling
Beat the peanut butter and butter until smooth. Add powdered sugar and vanilla, then mix in milk one tablespoon at a time until the filling is creamy and spreadable.
Assemble the cookies
Spread or pipe the filling onto the flat side of one cookie, then sandwich with another cookie. Repeat with remaining cookies.
Delicious Variations
Chocolate-dipped Nutter Butters
Dip half of each assembled cookie into melted chocolate and let set for a chocolate-peanut butter twist.
Crunchy peanut butter cookies
Swap creamy peanut butter for crunchy in the cookie dough to add extra texture.
Mini sandwich cookies
Make smaller cookies for bite-sized treats that are perfect for parties or lunchboxes.
Honey peanut butter filling
Replace a portion of the powdered sugar with honey for a slightly softer, more complex sweetness.

Frequently Asked Questions
Can I use natural peanut butter?
Natural peanut butter is not recommended because it can make the dough too oily and cause spreading.
Do these cookies need to be refrigerated?
They don’t need refrigeration for short-term storage, but chilling helps them last longer.
Can I freeze the dough?
Yes, shape the dough into ovals and freeze for up to 2 months. Bake from frozen, adding a minute or two to the bake time.
Why did my cookies spread too much?
This usually happens if the butter was too warm. Chilling the dough briefly can help.
Can I make these gluten-free?
Yes, use a 1:1 gluten-free all-purpose flour blend for best results.
How thick should the filling be?
The filling should be thick but spreadable—soft enough to pipe, but firm enough to hold the sandwich together.
