Peanut Butter Sandwich Cookies – A Sweet, Creamy Treat You’ll Crave
There’s something magical about sandwich cookies. Two soft, chewy layers hugging a creamy, sweet filling—it’s the ultimate comfort bite. For me, peanut butter sandwich cookies aren’t just a dessert; they’re a bite of nostalgia. The smell of warm peanut butter filled the air, and my very first attempt ended with cookies so flat they could have been coasters. But every batch since then has been a little better—until I landed on this recipe. It’s soft yet sturdy, rich yet balanced, and tastes like home in every bite.
When you bake these, your kitchen fills with that unmistakable peanutty aroma, like the gooey s’mores sandwich peanut butter cookies I’ve made before, but with an even creamier twist. And the best part? You don’t need a mixer the size of a truck or any fancy equipment—just a bowl, a spoon, and a little love.
The Story Behind These Peanut Butter Sandwich Cookies
I’ve always believed that the best desserts have a story, and this one started with my love for simple, homemade treats that make people smile. Peanut butter was a staple in the house growing up—on toast, in oatmeal, and, of course, in cookies. The first time I sandwiched two cookies together with a silky peanut butter filling, I knew I’d struck gold. They were a hit at a family cookout, where my aunt whispered, “These taste better than anything from the store.” That’s when I realized—this recipe was a keeper.
What makes these sandwich cookies stand out is the balance between texture and flavor. The cookie itself is tender with a slight chew, while the filling is smooth, sweet, and just the right amount of salty. If you’ve tried my peanut butter chocolate chip cookie bites, you’ll love how this recipe takes that peanut-chocolate magic and focuses it entirely on peanut butter indulgence.
Why These Sandwich Cookies Are a Must-Bake
These aren’t just cookies—they’re a baking experience. The dough is forgiving, making it beginner-friendly, and the assembly is fun enough to get kids involved. The filling whips up in minutes, so you’re never far from that first, heavenly bite. Plus, they keep beautifully in an airtight container for days—though if your house is anything like mine, they’ll be gone long before then.

Ingredients for the Best Peanut Butter Sandwich Cookies
When it comes to making truly irresistible peanut butter sandwich cookies, every ingredient matters. I stick to pantry staples, but I choose them with intention for maximum flavor and texture. Let’s break them down so you know exactly why each one is in the mix.
Peanut Butter – The Star of the Show
The heart of these sandwich cookies is, of course, creamy peanut butter. I recommend a no-stir, commercial brand for consistent results—natural peanut butter tends to separate and can throw off the dough texture. Peanut butter not only brings that rich, nutty flavor but also helps give the cookies their soft bite. If you’ve ever baked my peanut butter s’mores oatmeal cookie bars, you know just how well peanut butter holds its own in dessert recipes.
Butter and Sugar – The Sweet, Creamy Base
Softened unsalted butter pairs beautifully with granulated sugar to create a light, fluffy base. Creaming these two together traps air in the dough, ensuring the cookies bake up tender instead of dense. This is the same creaming magic that makes my chocolate peanut butter cookies so melt-in-your-mouth soft.
Eggs, Vanilla, and the Dry Mix
A single large egg binds the dough while adding richness. Vanilla extract deepens the flavor, giving each bite a warm, bakery-style aroma. The dry ingredients—flour, baking soda, and salt—are measured precisely to avoid spreading and ensure the cookies hold their shape when sandwiched.
How to Make Peanut Butter Sandwich Cookies Like a Pro
Baking these sandwich cookies is straightforward, but there are a few little tricks that make all the difference between “good” and “wow.” Let’s get into the steps so your cookies come out bakery-perfect every time.
Step 1 – Prep and Preheat for Success
Start by preheating your oven to 350°F (175°C). Line a baking sheet with parchment paper to prevent sticking and promote even baking. This step might seem simple, but starting with the right oven temp ensures your cookies spread just enough without going flat.
Step 2 – Cream the Butters and Sugar
In a large mixing bowl, combine the creamy peanut butter, softened unsalted butter, and granulated sugar. Beat until the mixture is fluffy and light—this should take about 2 minutes. This step is what gives your cookies their tender crumb and irresistible texture. If you’ve made my peanut butter brownies before, you’ll recognize that same “fluffing” stage that makes the difference between average and amazing.
Step 3 – Add the Egg and Vanilla
Mix in the large egg and vanilla extract until well incorporated. Scrape down the sides of the bowl so no streaks remain. This binding step ensures the dough holds together beautifully when you form the cookies.
Step 4 – Combine Dry Ingredients Separately
In a second bowl, whisk together the all-purpose flour, baking soda, and salt. Slowly add the dry mixture to the wet ingredients, mixing until just combined—overmixing can toughen the cookies. This is the same careful folding I use when making chocolate-dipped s’mores sandwich cookies, and it’s key for keeping the cookies soft.
Step 5 – Shape and Bake
Scoop tablespoon-sized portions of dough and roll them into balls. Place them about 2 inches apart on the baking sheet, then gently flatten with your palm or the bottom of a glass. Bake for 10–12 minutes, until the edges turn lightly golden. Let them cool completely before filling.
Making the Filling and Assembling the Sandwich Cookies
This is where the magic happens—turning two delicious cookies into one unforgettable treat.
Step 6 – Whip Up the Creamy Peanut Butter Filling
In a medium bowl, beat together the softened unsalted butter and creamy peanut butter until smooth. Add the powdered sugar gradually, mixing until fully incorporated. Drizzle in the heavy cream or milk a tablespoon at a time until you reach a fluffy, spreadable consistency. The filling should hold its shape but still be soft enough to bite into easily.
Step 7 – Assemble and Enjoy
Pair cookies of similar size. Spread or pipe the filling onto the flat side of one cookie, then gently press the second cookie on top to create a sandwich. Continue until all cookies are filled. Store in an airtight container at room temperature for up to four days.
How to Store & Serve
- Storage:
- Store in an airtight container at room temperature for up to 4 days or in the refrigerator for up to 1 week to maintain freshness.

- Tip: Wrap individually for easy grabbing.
- Serving:
- Serve at room temperature for soft cookies or chilled for a firmer filling. Pair with milk, coffee, or hot cocoa for a cozy treat.
- Tip: Add garnishes like chopped peanuts just before serving, a style you’ve valued in recipes like the American Flag Cookie Pie.
