Ingredients for butterscotch rice krispie
Rich caramelized butter meets crispy cereal clusters—just these nine ingredients create decadent butterscotch treats.
| Ingredient | Amount | Notes |
|---|---|---|
| Unsalted Butter 🧈 | ½ cup | Cold, cut into small cubes |
| Butterscotch Chips 🍬 | 1 cup | High-quality, not butterscotch candy |
| Mini Marshmallows 🍫 | 4 cups | Unmelted, standard size |
| Rice Krispies Cereal 🍞 | 6 cups | Original, not crispy treats |
| Granulated Sugar 🍚 | ¼ cup | Fine grain for smooth texture |
| Vanilla Extract 🌿 | 1 tsp | Pure, high-quality extract |
| Diamond Crystal Kosher Salt 🧂 | ¼ tsp | Fine grain for balance |
| Heavy Whipping Cream 🥛 | ¼ cup | Full-fat for richness |
| Aluminum Foil 📄 | 1 sheet | For easy release |
The butterscotch chips and butter form the flavor foundation—look for high-quality chips at specialty stores like Trader Joe's or Williams Sonoma. The difference between butterscotch chips and candy is crucial: chips melt smoothly while candy stays grainy. For the butter, unsalted is essential—it gives you control over the final saltiness. I always use Land O'Lakes or Plugrá for consistent results. The marshmallows should be mini size for even distribution, and Kraft Marshmallows are my go-to for reliable melting.
No butterscotch chips? Substitute caramel chips at a 1:1 ratio, though the flavor will be slightly different. Running out of mini marshmallows? Regular marshmallows chopped into quarters work in a pinch, but they won't be as uniform. For a deeper butterscotch flavor, add 1 tsp butterscotch extract to the butter mixture. The Rice Krispies must be the original variety—crispy treats or other varieties won't provide the same texture. If you're concerned about the treats being too sweet, reduce the sugar by 1/4 tsp and increase the vanilla to 1.5 tsp for balance.
Line your baking sheet with foil for easy release—parchment paper works too but may not be as sturdy. These treats keep well in an airtight container at room temperature for 5-7 days, though they're best enjoyed within 3 days for maximum freshness. For a restaurant-quality presentation, cut into 1-inch squares and dust with extra butterscotch chips. Portion into individual servings for holiday gatherings—they disappear fast.
Why You'll Love This Recipe
- Here’s what sold me: that butterscotch-butter base isn’t just sweet—it’s rich, with those chips melting into a glossy layer over the marshmallows. The Rice Krispies add that signature snap, but the real star? The way the sugar crystals cling to every bite, like tiny edible fireworks. (Yes, even on a Tuesday night.)
- I’ll be real: I rarely make enough for just one sitting. The good news? It stays crispy for days if you store it right (airtight container, room temp). The bad news? You’ll probably eat half the batch straight from the pan while it’s still warm. Budget-friendly, foolproof, and always there when you need it.
Step-by-step instructions for butterscotch rice krispie treats
Here's the method to achieve perfectly caramelized butterscotch treats with crispy clusters and a smooth texture.
Melt Butter and Butterscotch Chips Together
Line a 9x13-inch baking pan with the aluminum foil, leaving an overhang for easy removal. In a large microwave-safe bowl, combine the 0.5 cup unsalted butter (cut into small cubes) and 1 cup butterscotch chips. Microwave on high for 1 minute, then stir until the butter and chips are fully melted and smooth. If the mixture isn't completely melted, microwave in 20-second intervals, stirring between each, until fully combined and glossy.
This step is crucial for creating the rich butterscotch base. The butter should be completely melted, and the chips should dissolve evenly. If you see any unmelted butter or undissolved chips, continue microwaving in short bursts to avoid overheating or burning.
Add Marshmallows and Stir Until Fully Melted
Immediately after melting the butter and butterscotch chips, add the 4 cups mini marshmallows to the bowl. Stir vigorously with a wooden spoon or silicone spatula until the marshmallows are completely melted and the mixture becomes smooth and glossy. This should take about 2-3 minutes of continuous stirring. The mixture will look like a thick, golden caramel when fully combined.
Here's the thing—don't rush this step. The marshmallows need to melt completely to create that signature gooey texture. If you see any unmelted marshmallows, continue stirring and microwaving in 10-second intervals until fully incorporated. The mixture should coat the back of a spoon smoothly.
Incorporate Sugar, Vanilla, Salt, and Cream
Remove the bowl from the microwave and let it cool for 1 minute. Then, add the 0.25 cup granulated sugar, 1 tsp vanilla extract, 0.25 tsp diamond crystal kosher salt, and 0.25 cup heavy whipping cream. Stir well until all ingredients are fully combined and the mixture is smooth. The sugar will help balance the sweetness, while the cream adds richness and helps bind the mixture.
This is where the flavor profile comes together. The salt enhances the butterscotch flavor, and the vanilla adds depth. Stir until the mixture is homogeneous and free of any lumps. The consistency should be thick but pourable—similar to warm honey.
Fold in Rice Krispies Cereal
Quickly add the 6 cups rice krispies cereal to the bowl and fold gently with a spatula or wooden spoon. Work fast—you only have about 1-2 minutes before the mixture starts to set. The goal is to distribute the cereal evenly without crushing it. You'll want to see clusters of cereal coated in the butterscotch mixture, but not completely submerged.
Don't overmix at this stage. The cereal should be lightly coated with the butterscotch mixture, creating those signature crispy clusters. If you press the mixture into the pan too firmly, you'll lose the airy texture that makes these treats so delightful.
Press into Pan and Cool Completely
Transfer the mixture to the prepared baking pan and press down firmly and evenly using a greased spatula or the back of a spoon. Press until the top looks smooth and the cereal is evenly distributed. Cover the pan tightly with the remaining aluminum foil and let it cool at room temperature for 1 hour. Then, refrigerate for an additional 2 hours or until fully set.
This cooling process is essential for achieving the perfect texture. The treats should firm up completely before cutting. If you cut them too soon, they'll be sticky and difficult to handle. Once fully cooled, lift the treats out of the pan using the foil overhang and cut into squares or bars with a sharp knife.
Pro Tips For Making Butterscotch Rice Krispie
- CRUSH THE CHIPPED BUTTERSCOTCH: Chop those butterscotch chips into tiny pieces—no bigger than a pea—or they’ll melt into clumps instead of blending smoothly. I learned this the hard way when my first batch had butterscotch globs that tasted like they’d been reheated from a sad microwave meal.
- MELT THE MARSHMALLOWS LAST: Add the mini marshmallows after the butter and sugar have fully melted and thickened slightly. Dump them in too early, and you’ll end up with a soupy mess that won’t set properly—trust me, your Rice Krispie treats will thank you.
- STOP WHEN IT LOOKS DONE: The mixture will look way thicker than you expect—it’s supposed to be like thick caramel, not runny syrup. Pull it off heat the second it coats the back of a spoon, or you’ll overcook the sugar and end up with burnt edges on your treats.
- USE A COOL PAN: Grease your pan with butter and dust it with a light layer of Rice Krispies before pouring the mixture—this prevents sticking and gives the bottoms a subtle crunch. (Yes, it’s extra work, but your first batch will save you from crying over broken treats.)
Best sauces and condiments for this recipe
Butterscotch Caramel Drizzle
Elevate your treats with a homemade butterscotch caramel drizzle made by simmering ½ cup heavy cream, ¼ cup brown sugar, and 2 tbsp butterscotch chips until thickened.
Drizzle over cooled treats for a glossy, decadent finish. I use a pastry brush for even coverage—just 1-2 tbsp per batch is plenty. 🍯
Salted Caramel Swirl
Add a salted caramel swirl by mixing ½ cup caramel sauce with 1 tsp flaky sea salt and spooning dollops onto the butterscotch mixture before pressing into the pan.
Drag a knife through the mixture to create marbled patterns. For extra richness, use store-bought salted caramel like Trader Joe’s or Smucker’s.
Chocolate Ganache Drizzle
For a chocolate-butterscotch fusion, drizzle with chocolate ganache made by melting ½ cup dark chocolate chips with ¼ cup heavy cream. Let it cool slightly before drizzling over the treats.
I recommend Ghirardelli 60% dark chocolate for a balanced sweetness. Use a piping bag for elegant swirls or simply spoon it over for a rustic look. 🍫
Caramelized White Chocolate
Infuse the butterscotch base with caramelized white chocolate by melting ½ cup white chocolate chips with 1 tbsp heavy cream and stirring into the marshmallow mixture. The white chocolate adds a creamy contrast to the rich butterscotch flavor. For extra flair, sprinkle crushed white chocolate on top before cooling. 💫
Spiced Honey Glaze
Balance the sweetness with a spiced honey glaze by heating ¼ cup honey with ½ tsp cinnamon and ¼ tsp vanilla extract until warm. Brush lightly over the treats for a subtle warmth.
This works especially well if your treats lean too heavy on butterscotch. I use Manuka honey for its deep flavor. 🍯
Toasted Coconut Streusel
Add texture with a toasted coconut streusel by mixing ¼ cup shredded coconut with 1 tbsp brown sugar and 1 tsp melted butter. Sprinkle over the treats before they set for a tropical twist.
Toast the coconut in a dry pan for 2-3 minutes until golden for extra crunch. 🥥

Frequently asked questions
Why do my butterscotch Rice Krispie treats turn out too sticky?
This usually happens if you cut them too soon or didn't cool them long enough. Let the treats cool at room temperature for 1 hour first, then refrigerate for 2 hours before cutting. Also, make sure your butterscotch chips are fully melted—any unmelted chips can create uneven texture. For extra firmness, chill the pan for 30 minutes before removing.
Can I make these treats without a microwave?
Melt the butter and butterscotch chips in a double boiler over medium-low heat, stirring constantly until smooth. Keep the heat low to prevent burning—5-7 minutes should do it. For the marshmallows, use a heat-safe bowl over simmering water and stir until fully melted. This method gives you more control over the temperature.
How do I prevent the cereal from getting soggy?
Work quickly when folding in the Rice Krispies—they absorb moisture fast! Use a light hand when pressing the mixture into the pan—too much pressure crushes the cereal. Also, make sure your butterscotch mixture is only warm (not hot) when adding the cereal—hot liquid melts the marshmallows too much, creating a sticky base. Let the treats cool completely before cutting.
What's the best way to store these treats?
Keep them fresh in an airtight container at room temperature for 5-7 days. For longer storage, freeze portions wrapped in plastic wrap for up to 3 months. To reheat, let frozen treats sit at room temperature for 10-15 minutes—they'll be just as delicious! Store-bought butterscotch chips last longer than homemade versions, so they're ideal for baking ahead.
Can I use regular marshmallows instead of mini?
Yes, but you'll need to chop them into quarters for even distribution. Regular marshmallows melt more slowly, so you may need to microwave the mixture in 10-second intervals while stirring until fully combined. The texture will be slightly different—mini marshmallows create those classic crispy clusters, while chopped ones give a smoother finish. For best results, stick with mini marshmallows if possible.
