Ingredients You’ll Need

1 cup salted butter, room temp: Softened (but not melted) butter adds creaminess and richness to the cookies.
1 cup creamy peanut butter, room temp: Choose a creamy variety for a smooth texture; natural peanut butter works too but may alter consistency.
1 cup granulated sugar: This sugar helps create a slight crispness on the outside while keeping the cookie soft inside.
1 cup light brown sugar, tightly packed: Provides moisture and a deeper flavor; can substitute with dark brown sugar for a more intense taste.
2 large eggs, room temp: Room temperature eggs incorporate into the dough better for a uniform texture.
2 teaspoons vanilla extract: Pure vanilla adds a warm, inviting flavor; avoid imitation for better depth.
2 ½ cups all-purpose flour: The base of the cookies; measure correctly for best results.
1 teaspoon baking soda: Helps the cookies rise to the perfect balance of soft and chewy.
1 teaspoon baking powder: Works alongside baking soda to ensure the cookies are light and fluffy.
Granulated sugar or coarse sugar for sprinkling: A sprinkle on top adds a lovely touch of sweetness and crunch.
1 cup salted butter, room temp: For the filling, it ensures smooth blending with the peanut butter.
1 cup creamy peanut butter, room temp: Same as before; it forms the heart of the filling.
3 ¾ cups powdered sugar: This helps create a smooth and sweet filling.
3 tablespoons whole milk: Added for desired consistency; can substitute with non-dairy milk if needed.

How to Make Peanut Butter Sandwich Cookies

Prepare the Dough: In a medium bowl, whisk together 2 ½ cups all-purpose flour, 1 teaspoon baking soda, and 1 teaspoon baking powder. Set this aside while you mix the wet ingredients.
Mix Wet Ingredients: In the large bowl of a stand mixer, combine 1 cup salted butter, 1 cup creamy peanut butter, 1 cup granulated sugar, and 1 cup light brown sugar. Beat on medium-high until light and fluffy, about 2 minutes.
Incorporate Eggs and Vanilla: At medium-low speed, add the 2 large eggs, one at a time, along with 2 teaspoons vanilla extract. Mix until fully combined.
Combine Dry Ingredients: Gradually add the dry flour mixture to the wet ingredients at low speed. Mix until dough is just incorporated. Wrap the dough tightly in cling wrap and refrigerate for at least an hour.
Prepare to Bake: Preheat the oven to 375°F and position the rack in the lower-middle section. Line a baking sheet with parchment paper or a silicone mat.
Shape Cookies: Form the dough into 1.5-inch balls and flatten them to about ½ inch thick. Use a fork to create a criss-cross pattern on each cookie, deep enough to leave an imprint. Keep the remaining dough in the fridge while you bake the first batch.
Bake Cookies: Place the cookies on the baking sheet and bake for 8-10 minutes, or until the edges are lightly browned. Sprinkle the hot cookies with granulated or coarse sugar immediately after removing them from the oven. Cool for a few minutes before transferring to a wire rack.
Make the Filling: While the cookies cool, beat together 1 cup salted butter and 1 cup creamy peanut butter with an electric mixer until smooth and fluffy. Gradually add 3 ¾ cups powdered sugar, mixing until smooth. Then, add 1 tablespoon of whole milk at a time until you reach your desired filling consistency.
Assemble Cookies: Once the cookies have completely cooled, spread the peanut butter filling evenly between two cookies, creating delicious sandwich cookies.

Storing & Reheating

Store your peanut butter sandwich cookies at room temperature in an airtight container for up to one week, making them a great treat to enjoy any time. If you prefer, keep them in the fridge for up to two weeks for a chillier snack. To freeze, layer the cookies in an airtight container with parchment paper between them, and they’ll stay good for up to three months. To refresh, simply let them sit at room temperature for a few minutes before indulging — they’ll be just like fresh from the oven!

Chef’s Helpful Tips

Make sure your butter and peanut butter are at room temperature for easy mixing.
Avoid overmixing the dry ingredients after adding them to maintain the cookies’ tender texture.
If your cookie dough is too sticky, a little extra flour can help; but be careful not to add too much.
Allow the cookies to cool completely before adding the filling to prevent it from melting.
Experiment with different types of peanut butter — chunky for extra texture, or even flavored varieties for a fun twist.

It’s hard to beat the comforting flavors of homemade peanut butter sandwich cookies. Their fluffy texture and rich taste make every bite a little piece of happiness. Feel free to get creative with the filling or add a sprinkle of sea salt on top for that perfect sweet-salty experience. I hope you’ll find the joy in making these as I do!

Recipe FAQs

Can I use natural peanut butter for these cookies?

Absolutely! Natural peanut butter will work, but it can change the texture slightly. Just keep in mind that natural varieties may be runnier, so you might need to adjust the amount of flour.

How should I store leftover cookies?

Store any leftovers in an airtight container at room temperature for up to a week. For longer storage, freeze them for up to three months, making sure to separate layers with parchment paper.

Can I make these cookies gluten-free?

Yes! Substitute regular all-purpose flour with a gluten-free flour blend. Just ensure your other ingredients, especially baking powder and soda, are also gluten-free.

What can I do if my filling is too thin?

If your peanut butter filling is too runny, try adding powdered sugar a tablespoon at a time until you reach your desired creamy consistency. Conversely, if it’s too thick, add a bit more milk.
