It is best to use “standard” creamy peanut butter (like Jif or Skippy). Natural oils can separate in cake-mix recipes, leading to a greasy cookie.

Pro Tip for Peanut Butter Lovers

Peanut butter cookies firm up a lot as they cool, so the secret to keeping them soft and tender is pulling them from the oven while the centers still look slightly puffy and underdone. The edges should be just set, not browned. Letting them finish on the warm baking sheet gives you that perfect soft‑chewy texture every time.

The mix and the peanut butter and jelly.
  • Yellow Cake Mix: The base for soft cookies with minimal measuring. It has all the dry ingredients you need.
  • Peanut Butter: Creamy variety for smooth texture (avoid natural PBs with oil separation).
  • Vegetable Oil & Eggs: Adds richness and structure to the dough.
  • Frosting: Butter + PB + powdered sugar + cream = rich, fluffy filling.
  • Jam: Strawberry is a classic, but feel free to mix it up.

Variations and Substitutions for Chewy Peanut Butter Cookies

You can mix up these peanut butter cookies by doing these variations.

  • The “J” in PB&J: Swap strawberry jam for grape jelly, raspberry preserves, or even apricot jam.
  • Chocolate Version: Use a Chocolate Cake Mix instead of yellow for a “Reese’s” style sandwich.
  • Crunchy Texture: Use crunchy peanut butter in the cookie dough for extra texture.
  • Nut-Free: While the flavor will change, you can substitute peanut butter with SunButter (sunflower seed butter).

Special Equipment Needed for these Cookie Sandwiches

You need standar equipment like an electric mixer with a paddle attachment, cookie sheets, etc. 

  • 1 1/2 Tablespoon Cookie Scoop: This is crucial for ensuring all 60 cookies are the exact same size so they match up perfectly as sandwiches.
  • Hand Mixer: Necessary for getting the frosting light and fluffy.
  • Silicone Baking Mats: Peanut butter dough can be oily; these mats help the cookies spread evenly without sticking. Parchment paper works well too.
  • Wire Rack: This will help the cookies cool quickly.

Prep Ahead Suggestions for Peanut Butter Filling for Sandwich Cookies

  • Prep Ahead: You can scoop and roll the dough balls in sugar, then freeze them on a tray. Once solid, toss them in a freezer bag. Bake directly from frozen (just add 2 minutes to the bake time).
  • Store: Store assembled cookies in an airtight container at room temperature for 2 days or in the fridge for up to 5 days.
  • Freeze: These freeze beautifully! Wrap individual sandwiches in plastic wrap and freeze for up to 3 months.

Alternate Cooking Methods for this Nutter Butter Dupe

You can make a small batch of the homemade peanut butter cookies or you can make soft and chewy peanut butter bars.

  • Air Fryer: You can bake these at 325°F for 7–9 minutes. Since air fryers vary, do a test cookie first!
  • Cookie Bars: Press half the dough into a 9×13 pan, bake for 10 minutes, spread the frosting/jam, and crumble the remaining dough on top before baking for another 10 minutes.

How to Store, Reheat and Use Leftovers

  • Storing: Store assembled cookies in an airtight container at room temperature for 2 days or in the fridge for up to 5 days.
  • Freeze: These freeze beautifully! Wrap individual sandwiches in plastic wrap and freeze for up to 3 months.
  • Reheating: If the cookies have firmed up in the fridge, a quick 5–10 seconds in the microwave will soften the frosting and make the cookie taste “fresh-baked.”
  • Leftovers: Crumble them into a parfait. Make a PBJ ice cream sundae. Turn them into a freezer treat. Use them as a topping for oatmeal or make PBJ cookie truffles.

Common Questions About This PBJ Cookies Recipe

My Cookies Spread Too Much. What Happened?

Your kitchen might be too warm, or the vegetable oil was measured a bit too generously. Try chilling the dough balls for 20 minutes before baking.

Can I Use a Different Oil for the Cookies?

Yes, melted coconut oil or even melted butter works as a 1:1 sub for vegetable oil.

Expert Tips for Making Peanut Butter Sandwich Cookies

Here are a few tips and tricks to make these sandwich cookies even better. Also a few other treats you can add to your dessert table.

  • Don’t Overbake: These cookies should look slightly underdone when you pull them out. They will firm up as they cool. If they get too brown, they will be crunchy rather than chewy.
  • The “Hatch” Trick: Dip your fork in the white sugar before pressing down on the dough balls to prevent the fork from sticking to the peanut butter dough.
  • Frosting Barrier: Always spread the peanut butter frosting first, then add the jam in the center. The frosting acts as a “dam” to keep the jam from leaking out the sides.

Equipment

Ingredients
 

  • Cookies
  • 15.25 ounces Yellow cake mix, 1 box
  • 2 Large eggs
  • 1 cup Creamy peanut butter
  • ½ cup Vegetable oil
  • cup Granulated sugar, for rolling
  • Peanut Butter Frosting
  • 2 tablespoons Unsalted butter, softened
  • 2 tablespoons Creamy peanut butter
  • 1 cup Powdered sugar
  • 2 tablespoons Heavy cream or milk
  • Filling
  • cup Strawberry jam

Instructions
 

  • Preheat the oven to 350 degrees F.
  • Line two baking sheets with parchment paper or silicone baking mats.
  • In a large mixing bowl, beat together the cake mix, eggs, peanut butter, and vegetable oil until a smooth dough forms, about 2 minutes.
  • Place the granulated sugar in a small bowl.
  • Using a 1½ tablespoon cookie scoop, portion the dough into balls and roll each one in the sugar until evenly coated.
  • Arrange the dough balls on the prepared baking sheets, leaving about 3 inches between each cookie.
  • Use a fork to gently press a crisscross pattern into each cookie, slightly flattening the dough.
  • Bake for 10 to 12 minutes, or until the cookies are set and lightly golden around the edges.
  • Allow the cookies to cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.
  • To make the frosting, beat together the butter, peanut butter, powdered sugar, and cream until smooth and fluffy. Add additional cream or powdered sugar as needed to reach a spreadable consistency.
  • Spread about 1 teaspoon of frosting onto the flat side of one cookie. Top the frosting with ½ to 1 teaspoon of strawberry jam.
  • Place a second cookie on top and gently press together to form a sandwich cookie.
  • Repeat with the remaining cookies, frosting, and jam.

Christina’s Notes

  • Use a conventional creamy peanut butter, such as Jif or Skippy, for the most reliable texture. Natural peanut butter can make the dough oily and crumbly.
  • If the dough feels sticky, refrigerate it for 10 to 15 minutes before scooping. This helps prevent excess spreading during baking.
  • Roll generously in sugar for the classic peanut butter cookie appearance and a lightly crisp exterior.
  • Press the cookies lightly with the fork. Deep impressions can make the cookies too thin for sandwiching.
  • Store assembled cookies in an airtight container in the refrigerator for up to 5 days.
  • Unfilled cookies can be frozen for up to 3 months. Thaw completely before filling and serving
