Cook Stuffed Peanut Butter Rice Krispie Treats Like This

Creating these delicious treats is straightforward. Follow these steps to ensure they come out perfectly every time.
Step 1: Prepare Your Baking Dish
Start by greasing a 9×13 inch baking dish with a little butter or non-stick spray. This will prevent the treats from sticking to the dish.
Step 2: Melt the Ingredients
In a large saucepan, combine the sugar and light corn syrup over medium heat. Stir constantly until the mixture comes to a boil. Once it’s boiling, let it boil for 1 minute without stirring. Remove from heat and stir in the creamy peanut butter and vanilla extract until smooth.
Step 3: Combine with Rice Krispies
Add the Rice Krispies cereal to the peanut butter mixture. Stir gently until all the cereal is fully coated with the gooey mixture.
Step 4: Layer the Mixture
Take about half of the Rice Krispie mixture and evenly press it into the bottom of the prepared baking dish. Use wax paper to help press it down firmly, ensuring it’s evenly spread.
Step 5: Add the Peanut Butter Cups
Remove the frozen Reese’s Peanut Butter Cups from the freezer and arrange them in a single layer on top of the pressed Rice Krispie layer.
Step 6: Add the Top Layer
With the remaining Rice Krispie mixture, carefully press it over the top of the Reese’s Peanut Butter Cups. Again, use wax paper to press it down evenly.
Step 7: Allow to Set
Let the treats sit at room temperature for about 30 minutes to an hour, or until they are set. Once set, cut them into squares.
Easy Ingredient Swaps

If you need to adjust the recipe for dietary preferences or availability, here are some easy swaps:
- Use brown rice syrup instead of light corn syrup for a natural sweetener.
- Substitute sunflower seed butter for peanut butter for a nut-free version.
- Swap out the Reese’s Peanut Butter Cups for any chocolate-covered candy of your choice, like Snickers or M&M’s.
- For a crunchy twist, add chopped nuts or crispy cereal into the mixture.
Insider Tips
- Make sure to press the mixture firmly into the baking dish for that perfect chewy texture.
- Freezing the Reese’s Peanut Butter Cups is crucial to keeping them intact when you cut into the treats.
- For an extra layer of flavor, consider drizzling melted chocolate over the top before serving.
- Store leftovers in an airtight container at room temperature for the best texture.

You can substitute with any nut or seed butter, such as almond butter or sunflower seed butter, depending on your dietary needs or preferences.
