How to Make Chocolate Peanut Butter Rice Krispie Cups

Ingredients

3 cups Rice Krispies cereal
1 cup (about 170 g) semisweet chocolate chips
1 cup (about 258 g) creamy peanut butter (stirred if natural)
1/2 cup (about 60 g) powdered sugar (confectioners’ sugar)
1/2 teaspoon vanilla extract
1/4 cup (57 g) unsalted butter

Optional ingredients and substitutions

Swap creamy peanut butter for crunchy peanut butter for added texture.
For vegan or dairy-free: use vegan butter and dairy-free chocolate chips.
To reduce sugar: replace powdered sugar with 3–4 tablespoons of honey or maple syrup (texture will change slightly).
For gluten-free: verify that your puffed rice is certified gluten-free (many Rice Krispies contain barley malt).
Sprinkle flaky sea salt on top for contrast.

Method & Process

Line a 12-cup muffin tin with paper or silicone liners; set aside.
In a small saucepan over low heat, combine the butter and peanut butter. Stir constantly until fully melted and smooth (about 2–3 minutes). Avoid high heat to prevent scorching.
Remove the saucepan from heat. Stir in the powdered sugar and vanilla extract until the mixture is smooth and combined. The powdered sugar helps firm the mixture.
Pour the peanut butter mixture over the Rice Krispies in a large mixing bowl. Stir with a spatula until the cereal is evenly coated—work quickly so the cereal keeps its crunch.
Spoon the coated cereal into the prepared muffin liners, pressing gently to form cup shapes (fill each liner nearly to the top if you want taller cups). Use the back of a measuring spoon or a small cup to press evenly.
Melt the chocolate chips in a microwave-safe bowl in 20–30 second bursts, stirring between bursts until smooth, or melt over a double boiler.
Drizzle or spoon the melted chocolate over each Rice Krispie cup, covering the top. Optionally sprinkle with flaky sea salt or chopped peanuts.
Refrigerate for at least 30 minutes, or until the chocolate has set. Remove from liners and serve.

Practical tips

Work quickly when coating the cereal so it retains crunch.
If the peanut butter mixture becomes too stiff to spread, warm it briefly (5–10 seconds) in the microwave.
Don’t over-press the mixture into the cups—too much compression makes them dense instead of light and crisp.

Presentation Tips

Plain: Serve as-is for a nostalgic, casual treat.
Garnished: Top with a light sprinkle of flaky sea salt, chopped roasted peanuts, or mini chocolate chips for contrast.
Elevated platter: Arrange on a cake stand with doilies and a scattering of whole peanuts for a party display.
Pairing: Serve with strong coffee, cold milk, or a scoop of vanilla ice cream for a dessert plate.

How to Store

Room temperature: Store in an airtight container at room temperature for up to 2 days. Keep out of direct sunlight and heat so chocolate doesn’t soften.
Refrigeration: Store in an airtight container in the fridge for up to 7 days. Bring to room temperature for best flavor and texture before serving.
Freezer: Individually wrap cups in plastic wrap and store in a freezer-safe container for up to 2 months. Thaw in the refrigerator before serving.

Chef’s Advice

Balance of textures: Use a creamy peanut butter for easier melting and binding; if using natural peanut butter, stir thoroughly to include oil and achieve smoothness.
Chocolate finish: For a glossy, thin chocolate layer, temper the chocolate or add 1 teaspoon of coconut oil when melting.
Consistent portions: Use a cookie scoop to portion the cereal mixture into muffin liners—this keeps the cups uniform and makes presentation tidy.
Accessibility: If making for children or events, consider using bite-size liners for mini cups—baking cups take less work and are portable.

Creative Twists

Vegan & dairy-free: Replace butter with a plant-based butter and use dairy-free chocolate chips; use pure maple syrup instead of powdered sugar if you prefer a less-sweet binder.
Salted caramel twist: Drizzle a thin layer of warmed caramel between the Rice Krispie layer and chocolate for a caramel peanut butter cup.
Nutty swap: Swap peanut butter for almond or sunflower seed butter to accommodate peanut allergies (use certified allergy-free ingredients if needed).
Add-ins: Fold in toasted coconut flakes or chopped pretzels to the cereal mix for extra texture and flavor.

All Your Questions Answered

Q: Can I make these without powdered sugar?
A: Yes — you can use 3–4 tablespoons of honey or maple syrup as a binder, but the texture will be slightly softer and less set-up firm than with powdered sugar.

Q: How can I prevent the cups from getting soggy?
A: Work quickly when coating the cereal, press gently (don’t over-compress), and store at room temperature in an airtight container for short-term use. Refrigerate if you need them to last longer.

Q: Are these gluten-free?
A: Not necessarily—many Rice Krispies contain malt (barley). To make them gluten-free, use a certified gluten-free puffed rice cereal.

Q: Can I make mini cups or bars instead?
A: Yes—use mini muffin liners for smaller bites or press the mixture into a lined 8×8-inch pan and chill; cut into bars once set.

Q: Healthier options—any tips?
A: Use natural peanut butter with no added sugar, select dark chocolate (70% cocoa) with less sugar, and reduce powdered sugar or replace with a small amount of pure maple syrup for a less-processed sweetener.
