For the Bottom Layer

Rice Krispies – Provides the structure and crunch for the sandwiches. Substitution: Gluten-free rice cereal can be used.
Creamy Peanut Butter – Adds richness and flavor. Note: Any type of peanut butter works; flavored varieties (e.g., chocolate) can also be used.
Honey – Acts as a natural sweetener, enhancing flavor while helping to bind the rice krispie mixture. Substitution: Maple syrup can be used for a vegan option.

For the Ice Cream Layer

Ice Cream – The creamy filling that adds cold sweetness. Note: Softened vanilla or any preferred ice cream flavor works well.

For the Top Layer

Remaining Peanut Butter – Create a delicious topping that enhances the overall flavor. Try mixing in a bit of cocoa powder for a chocolate twist.

How to Make Peanut Butter Rice Krispie Ice Cream Sandwiches

Mix the Bottom Layer: In a large bowl, combine ¾ cup + 2 tablespoons of peanut butter with 2 tablespoons of honey. Stir in 4 cups of Rice Krispies until everything is fully mixed. Press this mixture into the bottom of a 9×13″ pan and freeze until firm, about 15-30 minutes.
Spread the Ice Cream: Once the bottom layer is firm, spread softened ice cream of your choice over it. Refreeze until the ice cream is slightly firm again, which takes about 30 minutes.
Prepare the Top Layer: In another bowl, mix the remaining peanut butter with the last bit of honey. Stir in the rest of the rice krispies and set this mixture aside for later use.
Assemble and Freeze: Pour the rice krispie mixture over the ice cream layer. Pat down evenly to ensure a good seal. Freeze until completely firm, taking about 1-2 hours.
Serve and Enjoy: Cut the frozen treat into squares and enjoy immediately, letting the nostalgia and flavor transport you back to carefree summer days.

Optional: Drizzle with chocolate sauce before serving for an extra indulgent touch.

Make Ahead Options

These Peanut Butter Rice Krispie Ice Cream Sandwiches are a lifesaver for busy home cooks looking to streamline their meal prep! You can prepare the bottom layer and freeze it up to 3 days in advance. Simply mix the peanut butter and honey with the Rice Krispies, press it into the pan, and freeze. The ice cream layer can be added just before serving; however, if prepped ahead, seal it well in the freezer. To maintain quality, ensure that the sandwiches are wrapped tightly in plastic wrap or stored in an airtight container. When you’re ready to enjoy, simply add the top layer, freeze for about 1-2 hours, and then slice into squares for a quick, delicious treat!

Expert Tips for Peanut Butter Rice Krispie Ice Cream Sandwiches

Soften Ice Cream Properly: Ensure ice cream is just soft enough to spread easily but not too melted, which can lead to messy layering in your sandwiches.
Sweetness Adjustments: For a sweeter krispie layer, swap some peanut butter with extra honey—this enhances flavor without compromising texture.
Use Quick-Freezing Techniques: If you’re short on time, place the pan in a slightly colder part of your freezer to speed up the firming process, but check frequently.
Cutting Technique: Use a sharp knife and a heated blade (dipped in hot water) for clean cuts, ensuring a beautiful presentation for your Peanut Butter Rice Krispie Ice Cream Sandwiches.
Experiment with Flavors: Don’t hesitate to mix in flavor extras like vanilla extract or cocoa powder to the peanut butter for added depth in your sandwiches.

Peanut Butter Rice Krispie Ice Cream Sandwiches Recipe FAQs

What kind of Rice Krispies should I use?
Absolutely! You can use traditional Rice Krispies for this recipe, but if you need a gluten-free option, simply swap them out for gluten-free rice cereal. They will provide the same delightful crunch and structure to your sandwiches.

How should I store the sandwiches?
