Ingredients for Peanut Butter Rice Krispie Treats

  • ¼ cup unsalted butter
  • 1 – 10 oz bag mini marshmallows (about 5 cups)
  • ½ cup peanut butter
  • 6 cups Rice Krispies cereal
  • 8 oz chocolate chips (about 1 ⅓ cups)
  • 2 teaspoons vegetable oil

How to Make Peanut Butter Rice Krispie Treats

Step 1: Prepare the Pan

Lightly grease a 9×13-inch pan with butter or non-stick cooking spray. This helps the treats come out of the pan easily once they’ve set.

Step 2: Melt Butter, Marshmallows, and Peanut Butter

In a large saucepan, melt the butter, mini marshmallows, and peanut butter together over low heat. Stir gently until everything is fully melted and smooth. Be sure to keep the heat low to avoid burning the marshmallows.

Step 3: Mix in Rice Krispies

Once the mixture is melted, remove it from the heat and stir in the Rice Krispies. Be sure to mix everything together thoroughly until the cereal is evenly coated in the peanut butter-marshmallow mixture.

Step 4: Press into the Pan

Pour the mixture into your prepared 9×13 pan and use a spatula or your lightly greased hands to press it evenly into the pan. Make sure it’s compacted but not too tight, as this will make it harder to cut later.

Step 5: Melt the Chocolate

Add the chocolate chips (or chopped chocolate) to a medium-sized heatproof bowl. Microwave the chocolate in 45-second intervals on medium power, stirring in between each burst. Continue until the chocolate is almost fully melted, then stir until smooth. Add the vegetable oil and mix well to make the chocolate nice and glossy.

Step 6: Pour the Chocolate

Pour the melted chocolate over the top of the Rice Krispie mixture in the pan. Spread it evenly with a spatula to cover the bars completely.

Step 7: Let the Treats Set

Let the treats harden at room temperature for about 2 hours. This will allow the chocolate to firm up and the Rice Krispie mixture to set into a deliciously chewy bar.

Step 8: Slice and Serve

Once the treats have cooled and set, cut them into squares and serve. Store leftovers in an airtight container at room temperature for up to a week. These treats are perfect for snacking, parties, or as a lunchbox treat!

Expert Tips for the Best Peanut Butter Rice Krispie Treats

  • Don’t overheat the marshmallows: Make sure you melt the marshmallows over low heat to avoid burning them. Stir constantly for a smooth, even mixture.
  • Add a pinch of salt: For a more balanced flavor, try adding a pinch of salt to the peanut butter mixture. This will enhance the flavors and give a nice contrast to the sweetness.
  • Customize the toppings: While chocolate is a classic topping, feel free to mix things up by adding chopped nuts, drizzle caramel over the top, or add some mini M&Ms for a pop of color.
  • Keep them soft: If your Rice Krispies treats seem a bit too hard after setting, try lightly pressing them into the pan and allow them to cool for a shorter time to keep them soft and chewy.

Common Mistakes to Avoid

  • Overpacking the mixture: When pressing the mixture into the pan, avoid over-packing it as this will make the treats too dense and difficult to cut.
  • Using high heat: Always melt the marshmallows and peanut butter over low heat to prevent them from burning or becoming too thick.
  • Not letting the chocolate set: Allow enough time for the chocolate to set before cutting the bars. Rushing this step could cause the chocolate to melt or smear when you cut into them.

Delicious Variations and Add-ins

  • Peanut Butter Chocolate Rice Crispy Bars: For an extra layer of flavor, try adding a peanut butter drizzle over the top of the chocolate for a double peanut butter treat.
  • Caramel S’mores Rice Krispie Treats: Mix in mini marshmallows and drizzle with caramel to create a s’mores-inspired variation. Check out our Caramel S’mores Rice Krispie Treats for a fun twist!
  • Nutty Crunch: Stir in some chopped peanuts or almonds for added texture and flavor. These nuts complement the peanut butter perfectly.

How to Store Peanut Butter Rice Krispie Treats

Store these Peanut Butter Rice Krispie Treats in an airtight container at room temperature for up to 5 days. If you want to freeze them, simply wrap the bars individually in plastic wrap and place them in a freezer-safe bag for up to 2 months. Thaw them at room temperature before serving.

Frequently Asked Questions (FAQs)

1. Can I make these bars without peanut butter?
Yes! You can substitute the peanut butter with almond butter, cashew butter, or sunflower seed butter for a different flavor.

2. How can I make these bars healthier?
For a healthier version, try using whole-grain rice cereal and natural peanut butter. You can also reduce the amount of sugar and chocolate or use dark chocolate for a less sweet topping.

3. Can I add other ingredients?
Definitely! Try adding dried fruit, such as raisins or cranberries, or mix in some chocolate chunks or mini marshmallows to the Rice Krispies for extra texture.

4. Are these Peanut Butter Rice Krispie Treats gluten-free?
Yes, these bars are naturally gluten-free, as long as you use gluten-free Rice Krispies cereal.
