These no-bake oat bars combine a bit of everything we love: they are extremely easy to make, very kid-friendly, have oats for a touch of healthiness, and that magic combination of peanut butter and chocolate. A great snack and dessert.

  • Total Time: 3 hours 30 minutes
  • Yield: 12 bars


  • 3/4 cup traditional oats
  • Large pinch of salt
  • 1 cup ground plain chocolate cookies
  • 2/3 cup confectioners sugar
  • 3 0z semisweet chocolate or 1/2 cup semi-sweet chocolate chips
  • 3/4 cup regular peanut butter
  • 6 tablespoons unsalted butter, divided

For the ganache topping:

  • 3 tablespoons cream (heavy or double)
  • 3 oz semisweet chocolate, chopped (or 1/2 cup chocolate chips)
  • Sprinkles for decoration, optional


  1. Have ready a buttered or sprayed 8-inch square pan lined with parchment paper.
  2. Heat peanut butter and butter until you can mix them. I use the microwave and a large mixing bowl. If you used a small container, transfer the mixture to a large bowl. 
  3. Stir in the oats, salt, ground cookies, sugar, and chocolate chips to the peanut butter mixture.
  4. Mix well with a silicon or rubber spatula or a wooden spoon until no dry parts remain. It might take a few minutes. The dough will be shiny and dark.
  5. Put it in the prepared pan, covering it as even and as smooth as possible. You might aid yourself with the back of a spoon that is lightly dipped in water.
  6. Refrigerate for several hours until it solidifies, and the oats absorb liquid and become chewier.
  7. When you’re ready to cut the bars, take the whole thing from the pan and transfer it to a board.
  8. In a bowl heat the cream with the chocolate until melted and smooth. I do it in the microwave in 10-second spurts, whisking well each time and making sure I don't scorch the chocolate.
  9. Pour it over the bars. You can spread it with a spatula or use a piping bag or fork to make a pattern.
  10. Sprinkle some confetti over it, if desired, before the chocolate settles.
  11. Keep leftovers refrigerated and well wrapped.


  • Substitution: you can replace the peanut butter for same amount of dulce de leche or almond butter.
  • Ganache: use milk chocolate if you like a sweeter bar or a mix of milk and semisweet.
  • Freezing: you can freeze it for a few weeks, well wrapped.
