This easy peanut butter sandwich cookies recipe makes about 24–30 irresistible sandwich cookies, depending on scoop size. Soft, tender peanut butter cookies are baked for just 8–10 minutes, cooled, and paired with a sweet, creamy peanut butter filling for a bakery-style treat that is simple enough for a weeknight and special enough for a cookie platter.
Each bite delivers rich peanut butter flavor, buttery brown sugar warmth, lightly crisp edges, and a smooth frosting center. The cookies are best when removed from the oven while their centers still look slightly soft, because they firm as they cool while keeping a tender texture.

These peanut butter sandwich cookies combine two classic comforts in one dessert: soft homemade peanut butter cookies and a fluffy peanut butter frosting. The cookie dough is mixed in one bowl after the dry ingredients are whisked separately, so the method is approachable even for newer bakers.
The finished cookies have enough structure to hold the filling, yet they remain pleasantly tender in the center. Brown sugar adds a gentle caramel note, while vanilla rounds out the nutty flavor and keeps the sweetness from tasting one-dimensional.
This recipe is also flexible for parties, bake sales, lunchbox treats, and holiday cookie trays. For another festive peanut butter bake, you can also browse our festive peanut butter cookie idea.
Ingredients You’ll Need
The cookie base begins with 1 cup of softened unsalted butter and 1 cup of creamy peanut butter. Using softened butter is important because it allows the fats and sugars to blend into a light, creamy mixture rather than leaving firm butter pieces throughout the dough.
- Granulated and brown sugars: One cup of each provides sweetness, color, and a soft, pleasantly chewy texture.
- Eggs and vanilla: Two large eggs add richness and help bind the dough, while 1 teaspoon of vanilla adds warmth.
- Dry ingredients: All-purpose flour, baking soda, baking powder, and salt create cookies that spread moderately and hold their sandwich shape.
- Filling ingredients: Softened butter, peanut butter, confectioners’ sugar, vanilla, and 2–3 tablespoons of milk or cream make a smooth, spreadable frosting.
Regular commercially processed creamy peanut butter is the most reliable choice here. Natural peanut butter can separate, which may make the dough or filling oily; if you use it, stir it extremely well and plan to chill the dough.

How to Make It Step-by-Step
Step 1: Heat the oven to 350°F (175°C), then line your baking sheets with parchment. The parchment helps prevent sticking and makes it easier to transfer these delicate cookies after baking.
Step 2: Add the softened butter, creamy peanut butter, granulated sugar, and packed light brown sugar to a large mixing bowl. Beat until the mixture looks light and creamy, scraping the sides of the bowl once or twice so the sugars are evenly incorporated.
Step 3: Beat in the two eggs one at a time, allowing the first egg to blend in before adding the second. Mix in the vanilla extract, which adds a mellow sweetness to the rich peanut butter base.
Step 4: In a separate bowl, whisk together the all-purpose flour, baking soda, baking powder, and salt. Gradually add this dry mixture to the wet ingredients, mixing only until no obvious streaks of flour remain.
Step 5: Check the dough before scooping. If it feels very soft or sticky, cover the bowl and chill it for about 30 minutes; this is particularly helpful with natural peanut butter and produces more uniform cookies.
Step 6: Scoop rounded tablespoons of dough onto the prepared baking sheets, leaving about 2 inches between portions. Flatten each one slightly with a fork for a traditional peanut butter pattern, or use the bottom of a glass for a smooth sandwich-cookie surface.
Step 7: Bake each batch for 8–10 minutes. Look for lightly browned, set edges and centers that still appear a little soft, since the cookies continue to firm as they cool.
Step 8: Let the cookies cool on the baking sheet for about 5 minutes before moving them to a wire rack. Cool them completely before adding frosting, or the filling may soften and slide.
Step 9: Make the filling by beating the softened butter and peanut butter until smooth. Add the confectioners’ sugar gradually with the vanilla, then beat in 2–3 tablespoons of milk or cream as needed until the frosting is creamy and easy to spread.
Step 10: Turn half of the cooled cookies flat-side up and spread or pipe frosting over them. Finish each sandwich with a second cookie, pressing gently until the filling reaches close to the edges.
Pro Tips for Soft, Even Cookies
The most important rule is to avoid overbaking. Peanut butter cookies can look unfinished in the center when they are actually ready, so trust the lightly browned edges and remove them while the centers remain slightly soft.
Measure flour carefully by spooning it into a measuring cup and leveling the top. Too much flour can make the cookies dense and dry, while too little can cause excessive spreading.
- Use room-temperature butter that is soft but not melted.
- Mix the dough only until the flour disappears.
- Chill sticky dough for about 30 minutes before scooping.
- Let cookies cool fully before filling.
- Use a piping bag or a small offset spatula for an even layer of frosting.

Filling, Pairing, and Serving Ideas
The peanut butter filling is sweet, creamy, and rich enough to taste special without requiring any unusual ingredients. Start with 2 tablespoons of milk or cream, then add the third tablespoon only if the frosting needs loosening.
For the neatest presentation, pipe a small spiral of filling onto the flat side of each cookie. If you prefer a generous homemade look, use a small spatula and leave a visible ribbon of frosting around the edge.
Serve the cookies with cold milk, coffee, hot chocolate, or black tea. They also pair well with fresh apple slices, banana slices, or a scoop of vanilla ice cream for a larger dessert.

Storage and Make-Ahead Advice
Store assembled cookies in an airtight container at room temperature. Arrange them in a single layer when possible, or place parchment between layers so the frosting does not stick to the cookies above it.
The baked cookies can be prepared ahead and cooled completely before assembly. You can also make the filling in advance, cover it, and let it soften at room temperature until it is easy to spread.
If you are building a varied cookie tray, pair these sandwich cookies with a delicate butter cookie such as this classic Danish butter cookie recipe. The contrast in shape and texture makes the platter look abundant and inviting.
Because the recipe makes approximately 24–30 sandwich cookies, it is well suited to gifting. Pack them snugly in a tin with parchment between layers and keep them away from heat so the filling remains firm.
