What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most of these are pantry staples, so you’re likely to have them on hand.

• Captain Crunch cereal: The star of the show! Its sweet, crunchy texture is the base of these bars.
• Reese’s Miniatures: These chocolate-peanut butter candies are chopped and layered for bursts of flavor in every bite.
• Mini marshmallows: Essential for binding the bars and adding that chewy texture.
• Unsalted butter: Melted to help blend everything together seamlessly.
• Peanut butter: Creamy works best here, but you can use chunky for added texture if you prefer.
• Vanilla extract: A small splash adds depth and rounds out the flavors.
• Pinch of salt: A little goes a long way in balancing the sweetness.

If you need substitutions, try almond butter instead of peanut butter for a nutty twist. For a gluten-free option, make sure your cereal is certified gluten-free. You can also swap Reese’s for another favorite candy, like Rolos or mini Snickers.

Equipment Needed

• Large mixing bowl: For combining the cereal and marshmallow mixture.
• Microwave-safe bowl: Perfect for melting the butter and peanut butter quickly.
• Rubber spatula: Helps spread the mixture evenly without sticking.
• 9×13-inch baking pan: The ideal size for these bars.
• Sharp knife: For chopping the Reese’s and cutting the bars into squares.

If you don’t have a microwave-safe bowl, you can melt the butter and peanut butter over low heat in a small saucepan. And if you’re short on baking pans, a disposable aluminum pan works just fine for gifting or transporting.

Preparation Method

1. Gather all your ingredients and prepare your work area. Lightly grease a 9×13-inch baking pan or line it with parchment paper for easy removal.
2. In a large microwave-safe bowl, melt 4 tablespoons of unsalted butter and 1 cup of creamy peanut butter together. Heat in 30-second intervals, stirring in between, until smooth and fully combined.
3. Stir in 1 teaspoon of vanilla extract and a pinch of salt for extra flavor.
4. Add 6 cups of Captain Crunch cereal to the melted mixture, gently folding until the cereal is evenly coated.
5. In a separate bowl, melt 4 cups of mini marshmallows using the same microwave method (or over low heat on the stove). Stir until smooth, then quickly mix it into the cereal mixture.
6. Fold in 1 cup of chopped Reese’s Miniatures, reserving a handful for topping.
7. Press the mixture firmly into the prepared baking pan using a rubber spatula. Sprinkle the reserved Reese’s pieces on top, pressing slightly to adhere.
8. Let the bars cool at room temperature for about 30 minutes before cutting into squares.

Pro tip: If the mixture feels sticky while pressing, lightly grease your spatula or fingers with butter—it makes the job much easier!

Cooking Tips & Techniques

Here are some helpful tips to ensure your Reese’s Peanut Butter Captain Crunch Bars turn out perfectly every time:

• Timing: Work quickly when combining the marshmallow mixture with the cereal to prevent it from hardening before it’s fully mixed.
• Even coating: Make sure the cereal is evenly coated with the marshmallow mixture for consistent texture in every bite.
• Pressing firmly: Don’t skimp on pressing the mixture into the pan—it helps the bars hold together better.
• Avoid over-melting: Be careful not to overheat the marshmallows, as this can make them hard and difficult to mix.
• Cleanup tip: Soak your bowls and utensils in warm water immediately after use—the marshmallow mixture can be stubborn once dried.

Variations & Adaptations

Here are some fun ways to adapt this recipe to suit your taste or dietary needs:

• Gluten-Free Version: Use a gluten-free cereal like Puffins or another certified gluten-free option.
• Seasonal Twist: Swap out Reese’s for festive candies like candy canes during the holidays or pastel M&Ms for Easter.
• Nut-Free Option: Replace the peanut butter with sunflower seed butter and use nut-free chocolate candies.
• Extra Crunch: Add chopped pretzels or crushed potato chips for a sweet and salty combo.

Personally, I’ve tried adding a drizzle of melted dark chocolate on top for an extra decadent touch—it’s a game changer!

Serving & Storage Suggestions

These bars are best served at room temperature, but trust me, they’re just as good straight from the fridge. Here’s how to store them:

• Room Temperature: Store in an airtight container for up to 3 days.
• Refrigeration: Keep them in the fridge for up to a week. Let them sit out for a few minutes before serving for best texture.
• Freezing: Wrap the individual bars in plastic wrap and store them in a freezer bag. They’ll keep for up to 2 months.

These bars pair beautifully with a tall glass of cold milk or a warm cup of coffee. For parties, arrange them on a pretty platter and watch them disappear!
