How To Make Peanut Butter Truffle Cookies

  1. Make the peanut butter filling. Mix creamy peanut butter with powdered sugar until smooth, then roll into small balls and freeze briefly to firm up.
  2. Prepare the chocolate cookie dough. Melt chocolate chips and butter together, then beat in sugars, eggs, and vanilla. Gradually add in the dry ingredients like flour and cocoa powder to form a thick, fudgy dough.
  3. Assemble the cookies. Scoop out portions of the chocolate dough, flatten each piece, and wrap it around a peanut butter ball, sealing the edges completely.
  4. Bake until set. Place the stuffed cookies on a lined baking sheet and bake at 350°F for 10-12 minutes or until the edges are set but the centers remain soft and slightly gooey.
  5. Add a finishing touch. Let the cookies cool, then drizzle with chocolate ganache or a sprinkle of sea salt for an extra layer of indulgence. Enjoy warm or store for later!

Recipe Tips & Tricks

  • Freeze the Peanut Butter Balls – Freezing the peanut butter filling for 15-20 minutes makes it easier to wrap in the dough without melting, ensuring a neat, creamy center.
  • Don’t Overbake – Bake just until the edges are set and the tops look slightly cracked. Overbaking can make the cookies dry and lose that fudgy texture.
  • Chill the Dough – If the dough feels too sticky to handle, pop it in the fridge for 15-20 minutes. This makes it easier to shape around the filling.
  • Use a Cookie Scoop – A medium cookie scoop helps keep the cookie dough portions even, making sure all the cookies bake up to the same size.

Storage

Store at room temperature in an airtight container for 3-4 days. You can freeze them in an airtight container for about 3 months. Just let them thaw at room temperature before serving.

These cookies are rich and chocolate-y almost like a brownie. The peanut butter center takes them to a whole new level. So if you have a peanut butter fan in your house, they are going to love these Buckeye Cookies and be on your must make list all year round!

Can I use natural peanut butter?

Yes, but keep in mind that natural peanut butter tends to be runnier. If you use it, you may need to add a little extra powdered sugar to thicken the consistency and make it easier to roll into balls.

How do I store leftover cookies?

Store these cookies in an airtight container at room temperature for up to 3 days. For longer storage, keep them in the refrigerator for up to a week, or freeze them for up to 3 months.

Can I make these ahead of time?

Yes! You can prepare both the peanut butter filling and the chocolate cookie dough up to 24 hours in advance. Keep them refrigerated separately until you’re ready to assemble and bake.
