1 cup (220 g) light brown sugar, packed
-
1 cup (250 g) creamy peanut butter
-
2 large eggs, room temperature
-
1 teaspoon (5 ml) vanilla extract
-
3 cups (375 g) all-purpose flour
-
1 teaspoon (5 g) baking soda
-
1/2 teaspoon (3 g) baking powder
-
1/2 teaspoon (3 g) salt
For the Peanut Butter Filling:
-
1/2 cup (113 g) unsalted butter, softened
-
3/4 cup (190 g) creamy peanut butter
-
2 1/2 cups (300 g) powdered sugar
-
2–3 tablespoons (30–45 ml) milk
-
1 teaspoon (5 ml) vanilla extract
Step-by-Step Instructions
1. Prepare the Dough
In a large mixing bowl, cream together 1 cup (226 g) softened unsalted butter, 1 cup (200 g) granulated sugar, and 1 cup (220 g) light brown sugar until light and fluffy, about 2–3 minutes.
Add 1 cup (250 g) creamy peanut butter and mix until fully combined. Beat in 2 large eggs and 1 teaspoon (5 ml) vanilla extract.
In a separate bowl, whisk together 3 cups (375 g) all-purpose flour, 1 teaspoon (5 g) baking soda, 1/2 teaspoon (3 g) baking powder, and 1/2 teaspoon (3 g) salt. Gradually add the dry ingredients to the wet mixture, mixing until a soft dough forms.
2. Chill the Dough
Cover and refrigerate the dough for at least 30 minutes. This helps the cookies hold their shape and prevents spreading.
3. Shape the Cookies
Preheat your oven to 350°F (175°C) and line baking sheets with parchment paper.
Scoop about 1 tablespoon (20 g) of dough and roll into an oval shape. Slightly flatten with your fingers. Use a fork to create crisscross marks on each half, mimicking the classic peanut shell design.
Place cookies about 2 inches (5 cm) apart on the baking sheet.
4. Bake
Bake for 8–10 minutes or until the edges are lightly golden. The centers should look set but not overly browned.
Allow cookies to cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
How to Make the Creamy Peanut Butter Filling
In a large bowl, beat together:
-
1/2 cup (113 g) softened unsalted butter
-
3/4 cup (190 g) creamy peanut butter
Mix until smooth and fluffy.
Gradually add 2 1/2 cups (300 g) powdered sugar. Add 2–3 tablespoons (30–45 ml) milk as needed to achieve a smooth, spreadable consistency. Stir in 1 teaspoon (5 ml) vanilla extract.
The filling should be thick but easy to pipe or spread.
Assembling the Sandwich Cookies
Once cookies are completely cool:
-
Spread or pipe about 1 tablespoon (15 g) of filling onto the flat side of one cookie.
-
Top with a second cookie, pressing gently to spread the filling evenly.
-
Repeat with remaining cookies.
Allow cookies to sit for 30 minutes to set before serving.
Tips for Perfect Homemade Peanut Butter Sandwich Cookies
Use Room Temperature Ingredients
Room temperature butter and eggs create a smoother dough and better texture.
Measure Flour Correctly
Spoon and level your flour instead of scooping directly from the bag to avoid dense cookies.
Don’t Overbake
The cookies will firm up as they cool. Slightly underbaked centers give the best texture.
Chill the Dough
Skipping the chilling step can cause excessive spreading.
Storage and Make-Ahead Tips
Store assembled cookies in an airtight container at room temperature for up to 4 days.
For longer storage:
-
Refrigerate for up to 1 week.
-
Freeze unfilled cookies for up to 3 months.
-
Freeze assembled cookies in a single layer, then transfer to freezer bags.
Let frozen cookies thaw at room temperature before serving.
Variations to Try
Chocolate-Dipped Peanut Butter Sandwich Cookies
Dip half of each assembled cookie in melted chocolate and let set.
Crunchy Peanut Butter Version
Replace creamy peanut butter with crunchy peanut butter for added texture.
Mini Nutter Butters
Use 1 teaspoon (10 g) dough portions for bite-sized treats.
Frequently Asked Questions
1. Can I use natural peanut butter?
Yes, but it may slightly change the texture. Natural peanut butter tends to be thinner and oilier. If using natural peanut butter, stir it thoroughly before measuring and consider reducing the milk in the filling by 1 tablespoon (15 ml) to maintain thickness. The cookies may spread a bit more, so chilling the dough is especially important. For the most authentic copycat texture, conventional creamy peanut butter works best because it has stabilizers that help maintain structure and consistency.
2. Why are my cookies spreading too much?
There are several possible reasons. The most common is skipping the chilling step. If the dough is too warm, the butter melts quickly in the oven, causing spreading. Another reason could be inaccurate flour measurement. Too little flour results in flat cookies. Make sure you measure 3 cups (375 g) of flour correctly using the spoon-and-level method. Finally, overly soft butter can contribute to spreading. It should be softened but not melted.
3. Can I make these cookies gluten-free?
Yes, you can substitute a 1:1 gluten-free all-purpose flour blend for the 3 cups (375 g) all-purpose flour. Choose a blend that contains xanthan gum for best structure. The texture may be slightly more delicate, but the flavor remains delicious. Be sure to chill the dough well and handle it gently when shaping. You may also want to test-bake one cookie first to ensure proper texture before baking the entire batch.
4. How do I get the filling perfectly smooth?
The key is properly softened butter and peanut butter. Beat 1/2 cup (113 g) unsalted butter until completely smooth before adding 3/4 cup (190 g) peanut butter. Gradually incorporate 2 1/2 cups (300 g) powdered sugar to prevent lumps. Adding 2–3 tablespoons (30–45 ml) milk slowly allows you to control consistency. If the filling feels too thick, add milk 1 teaspoon (5 ml) at a time. If too thin, add additional powdered sugar 1 tablespoon (8 g) at a time. Beating the mixture for 2–3 minutes ensures a fluffy, pipeable texture.
