Peanut Butter Sandwich Cookies: A Classic Treat with a Creamy Center

Peanut butter sandwich cookies bring together two soft, nutty cookies and a sweet, creamy filling. They’re a comforting homemade treat for lunchboxes, bake sales, holiday cookie trays, or an afternoon snack. The cookies are easy to make, and the filling can be adjusted to suit your taste—from lightly sweet to extra rich.

What Makes a Great Peanut Butter Sandwich Cookie?

A delicious sandwich cookie balances texture and flavor. The cookies should be tender enough to bite through without crumbling, with plenty of roasted peanut flavor. A smooth buttercream-style filling adds sweetness and holds the cookies together. For an extra touch, a little salt in the dough or filling keeps the sweetness in check.

Ingredients

For the cookies:

• 1 cup creamy peanut butter
• ½ cup unsalted butter, softened
• ¾ cup packed brown sugar
• ¼ cup granulated sugar
• 1 large egg
• 1 teaspoon vanilla extract
• 1½ cups all-purpose flour
• ½ teaspoon baking soda
• ¼ teaspoon salt

For the filling:

• ¼ cup unsalted butter, softened
• ½ cup creamy peanut butter
• 1½ cups powdered sugar
• 1 to 2 tablespoons milk
• ¼ teaspoon vanilla extract

How to Make Peanut Butter Sandwich Cookies

1. Heat the oven. Preheat the oven to 350°F. Line two baking sheets with parchment paper.
2. Mix the wet ingredients. In a large bowl, beat the peanut butter, softened butter, brown sugar, and granulated sugar until creamy. Beat in the egg and vanilla.
3. Add the dry ingredients. In a separate bowl, whisk together the flour, baking soda, and salt. Gradually stir the dry mixture into the peanut butter mixture just until combined.
4. Shape the cookies. Scoop the dough into small balls, about 1 tablespoon each, and place them on the prepared baking sheets. Leave space between the cookies. Flatten each ball gently with a fork, making a crisscross pattern if desired.
5. Bake and cool. Bake for 8 to 10 minutes, until the edges are set and the centers still look slightly soft. Let the cookies rest on the baking sheet for a few minutes, then transfer them to a rack to cool completely.
6. Make the filling. Beat the butter and peanut butter until smooth. Add the powdered sugar, vanilla, and 1 tablespoon of milk. Beat until fluffy, adding a little more milk if needed to make the filling spreadable.
7. Assemble. Spread or pipe filling onto the flat side of one cooled cookie. Top with another cookie and press gently. Repeat with the remaining cookies.

Tips for the Best Results

• Use room-temperature ingredients. Softened butter and a room-temperature egg blend more evenly into the dough.
• Don’t overbake. Peanut butter cookies can dry out if left in the oven too long. They’ll continue to set as they cool.
• Let cookies cool fully before filling. Warm cookies can soften or melt the filling.
• Adjust the filling to taste. Add powdered sugar for a firmer, sweeter filling, or a small splash of milk for a softer texture.
• Try a different texture. Swap creamy peanut butter for crunchy peanut butter in the cookies, or add a little finely chopped chocolate to the filling.

Storing and Serving

Store assembled cookies in an airtight container at room temperature for up to three days, or refrigerate them for up to a week. For a softer bite, let refrigerated cookies sit at room temperature briefly before serving. The baked, unfilled cookies can also be frozen in an airtight container; thaw them completely before adding the filling.

With their tender peanut butter cookies and smooth, sweet center, these homemade sandwiches are simple to customize and easy to share. Serve them with a glass of milk, pack them for a treat on the go, or enjoy one whenever a classic peanut butter dessert sounds just right.

Creamy peanut butter filling between two soft cookies.

One of the best things about peanut butter sandwich cookies is the creamy peanut butter filling tucked between two soft, tender cookies. Each bite combines smooth, nutty richness with a gentle sweetness, while the soft cookies make the filling feel extra satisfying.

A classic flavor combination loved by many.

Peanut butter sandwich cookies bring together two familiar favorites: rich, nutty peanut butter and a sweet, creamy filling. This classic flavor combination appeals to kids and adults alike, making the cookies a welcome treat for family gatherings, lunchboxes, and dessert trays.

Great for snacks, parties, and lunchboxes.

Peanut butter sandwich cookies are a versatile treat that fits just about any occasion. Enjoy one as a satisfying afternoon snack, arrange a batch on a platter for parties, or tuck one into a lunchbox for a sweet surprise. Their portable size and familiar peanut butter flavor make them easy to share and fun to enjoy anywhere.

Easy to customize with chocolate or crunchy peanuts.

Peanut butter sandwich cookies are easy to customize, so you can make each batch your own. Add chocolate chips or a drizzle of melted chocolate for a richer treat, or mix crunchy peanuts into the filling for extra texture. These simple additions pair beautifully with the creamy peanut butter flavor and make the cookies easy to tailor to different tastes.

Simple to make with everyday baking ingredients.

Peanut butter sandwich cookies are simple to make with everyday baking ingredients, many of which may already be in your pantry. Peanut butter, flour, sugar, butter, and an egg come together to make soft, flavorful cookies, while a quick filling adds a creamy finishing touch. With straightforward steps and no special equipment required, they’re an easy baking project for both beginners and experienced home cooks.

Convenient to pack and share.

Peanut butter sandwich cookies are easy to pack and share, making them a handy treat for lunchboxes, picnics, road trips, and parties. Their filling is tucked between two cookies, so they’re less messy to carry and simple to portion out for friends, family, or coworkers.

Delicious with a cold glass of milk.

Peanut butter sandwich cookies and a cold glass of milk make a comforting, classic pairing. The milk’s cool, creamy taste balances the cookies’ rich peanut butter flavor and sweet filling, making every bite even more satisfying.

Can be high in sugar and calories.

Peanut butter sandwich cookies can be high in sugar and calories, especially when they have a generous layer of sweet filling. Enjoying them in moderation and paying attention to portion sizes can help you savor the treat while keeping it in balance with your overall eating habits.

May trigger peanut allergies.

Peanut butter sandwich cookies contain peanuts, a common food allergen, and may trigger reactions in people with a peanut allergy. Reactions can be serious, so check ingredient labels carefully and avoid serving these cookies to anyone with a peanut allergy. When sharing treats, clearly label them and prevent cross-contact with peanut-containing ingredients or equipment.

Filling can make cookies very sweet.

The creamy filling is part of what makes peanut butter sandwich cookies so appealing, but it can also make them overly sweet, especially when paired with sugary cookies. To keep the flavor balanced, use less filling, reduce the powdered sugar, or add a pinch of salt to bring out the peanut butter’s savory notes.

Can crumble if overbaked.

Peanut butter sandwich cookies can crumble easily if they’re overbaked. Even a minute or two too long in the oven can dry them out, making the cookies fragile and more likely to break when you add the filling or take a bite. For a tender texture, remove them when the edges are set but the centers still look slightly soft, then let them finish cooling on the baking sheet.

May soften during storage.

Peanut butter sandwich cookies may soften during storage, especially when the filling’s moisture moves into the cookies. To help them keep their texture, store them in an airtight container in a cool place and avoid stacking them while the filling is still soft. For a firmer bite, refrigerate the cookies or store the cookies and filling separately, then assemble them shortly before serving.

Take extra time to assemble.

One drawback of peanut butter sandwich cookies is that they take extra time to assemble. After baking, the cookies need to cool completely before you can add the filling, then each pair must be matched and spread or piped with care. It’s a little more work than making a batch of regular cookies, especially when you’re preparing a large quantity.
