Ingredients for butterscotch rice krispie
Nine ingredients transform into golden, crisp-edged butterscotch Rice Krispie treats—no oven needed.
| Ingredient | Amount | Notes |
|---|---|---|
| Butter, Unsalted 🧈 | 1 cup | Cut into 2 tbsp pieces for even melting |
| Large Marshmallows 🍬 | 6 cups | Mini marshmallows work too, adjust quantity |
| Rice Krispies Cereal 🍞 | 6 cups | Original flavor preferred |
| Butterscotch Chips 🍪 | 2 cups | Crushed for even distribution |
| Butterscotch Flavor Extract 🍯 | 1 ½ tbsp | Or 2 tbsp butterscotch syrup |
| Vanilla Extract 🌿 | 1 tsp | Pure, high-quality preferred |
| Salt 🧂 | ½ tsp | Fine sea salt for subtle seasoning |
| Unsweetened Cocoa Powder 🍫 | 1 tbsp | Optional for deeper flavor |
| Vegetable Oil 🫒 | 1 tbsp | Prevents sticking during cutting |
The butter and marshmallows are the heart of this recipe. Use European-style butter (like Plugrá) for higher fat content—it creates that signature glossy finish. Marshmallows should be fresh; if they're sticky or shriveled, they won't melt properly. For the butterscotch depth, I always opt for high-quality chips from Ghirardelli—they're worth the splurge. The cocoa powder is optional but adds that subtle depth that makes these taste like a bakery treat. If you're using syrup instead of extract, Karo brand is the most reliable for consistency.
No butterscotch chips? Crushed toffee bits or butterscotch-flavored candy melts work in a pinch, though texture will differ slightly. Short on vanilla? Double the extract for more aromatic punch. The vegetable oil is non-negotiable—it keeps the treats from sticking to your hands when cutting. For a richer flavor, add 1 tbsp of butterscotch-flavored coffee creamer powder to the dry ingredients. If you're making these for a party, double the batch—they disappear fast (trust me, I've hosted plenty).
Store cut treats in an airtight container with parchment paper between layers for up to 5 days. For longer storage, freeze uncut sheets for 3 months. The oil prevents sticking, but if you're still struggling, lightly grease your hands with more oil before cutting. These reheat beautifully—pop them in the microwave for 10-15 seconds to restore that warm hug feeling. Leftovers? Wrap individually for perfect little gifts.

Step-by-step instructions for butterscotch Rice Krispie treats
Here's how to make these rich, caramelized treats with perfect butterscotch flavor and crispy edges.
Melt Butter and Prepare the Butterscotch Mixture
Line a 9x13-inch baking pan with parchment paper, leaving overhang on two sides for easy removal. In a large, heavy-bottomed saucepan, melt the 1 cup unsalted butter over medium-low heat. I like to cut the butter into 2-tablespoon pieces first for even melting.
Once completely melted, remove from heat and stir in the 2 cups crushed butterscotch chips, 1.5 tablespoons butterscotch flavor extract, 1 teaspoon vanilla extract, 0.5 teaspoon salt, and 1 tablespoon unsweetened cocoa powder. The mixture should thicken slightly as it cools—this is normal. If it becomes too thick, return to low heat for 10-15 seconds to loosen it.
Add Marshmallows and Stir Until Fully Coated
Return the butterscotch mixture to medium-low heat and add the 6 cups large marshmallows all at once. Stir constantly with a wooden spoon or silicone spatula until the marshmallows are completely melted and the mixture is smooth, about 3-4 minutes. This is where patience pays off—uneven melting creates lumpy treats.
Watch closely as the mixture transforms from chunky to glossy. You'll know it's ready when it coats the back of a spoon smoothly and pulls away cleanly. If any marshmallows remain unmelted, add 1 teaspoon water and stir until fully incorporated. Remove from heat immediately to prevent burning.
Mix in Rice Krispies and Press into Pan
Quickly stir in the 6 cups Rice Krispies cereal with the wooden spoon—work fast while the mixture is still warm and pliable. The cereal will absorb the butterscotch mixture instantly, creating a thick, caramelized dough. Pour the mixture into the prepared pan and press firmly with a greased 8x8-inch square of parchment paper or a damp spatula.
Press down evenly until the treats reach the edges of the pan and the top looks smooth. For extra crispy edges, I like to press the mixture against the sides of the pan with my fingers. The 1 tablespoon vegetable oil you'll use later is for greasing your tools—this prevents sticking when cutting.
Cool and Cut for Perfect Squares
Let the treats cool completely at room temperature for 1-2 hours before cutting. This ensures clean slices and prevents the butterscotch from oozing out. While they cool, lightly grease your knife with the 1 tablespoon vegetable oil to prevent sticking.
Once fully set, use the greased knife to cut into 16 equal squares (about 2x2 inches each). For perfectly clean edges, press down firmly as you cut. Store in an airtight container at room temperature for up to 5 days, or freeze for 3 months—they only get better with time as the flavors meld.
Pro Tips For Making Butterscotch Rice Krispie
- Melt Butter Slowly: I used to dump all the butter in at once, and it’d either seize up or burn before the marshmallows melted. Instead, cut the butter into small cubes and add them in batches—about 1 tablespoon at a time—while stirring constantly. The heat should be medium, not high, or you’ll scorch the butterscotch flavor before the marshmallows even soften.
- Crush Chips Lightly: Whole butterscotch chips make the texture uneven—some batches turn out gummy, others too crunchy. Roughly crush 3/4 of the chips (leave a few whole for texture) and fold them in after the marshmallows have melted but before adding the cereal. This ensures they melt just enough to coat the Rice Krispies without turning into a sticky mess.
- Skip Pre-Measuring Cereal: Measuring Rice Krispies by volume (cups) leads to clumps and uneven distribution. Instead, pour the cereal directly from the box into the pot in a steady stream while stirring vigorously—this breaks up any clumps and guarantees even coating. (Yes, it’ll look messy at first, but the result is smoother every time.)
- Add Extract Last: Butterscotch extract is potent—too early, and the heat will cook it off before the marshmallows melt. Stir in the extract (about 1 teaspoon) right after removing the pot from heat, then immediately fold in the remaining whole butterscotch chips. This locks in the flavor without overpowering the buttery sweetness.
Essential equipment for this dish
Heavy-Bottom Saucepan
This is my go-to tool for melting butter and marshmallows—it prevents scorching and ensures even heat distribution. I recommend a 3-quart stainless steel saucepan like All-Clad or Calphalon.
The extra weight helps stabilize temperature, which is critical when melting marshmallows. If you don’t have one, a heavy-duty enamel Dutch oven works too. 🔥
Wooden Spoon or Silicone Spatula
Stirring melted marshmallows requires a tool that won’t melt or scratch your pan. A wooden spoon (like Oxo Good Grips) is classic, but a heat-resistant silicone spatula (like Epicurean) is gentler on your hands and easier to clean. Avoid metal—it can cause hot spots and burn the mixture.
9x13-Inch Baking Pan
A lightly greased or parchment-lined 9x13-inch pan is essential for shaping these treats. I prefer Wilton’s non-stick baking pans because they’re durable and release treats easily. Line it with parchment paper for foolproof removal—just leave an overhang on two sides to grip and lift.
For extra crispy edges, press the mixture firmly against the pan’s sides.
Greased Cutting Tools
After cooling, you’ll need a sharp chef’s knife (like Victorinox 8-inch) and 1 tablespoon vegetable oil for greasing. Lightly coat your knife before cutting to prevent the butterscotch from sticking.
For larger batches, a pizza cutter works faster—just grease the wheel first. A damp paper towel wrapped around your fingers helps press the mixture into the pan without sticking.
Parchment Paper Squares
Use 8x8-inch squares of parchment paper to press the mixture into the pan. They’re easier to handle than spatulas and create a smooth, even surface. I keep a roll of Reynolds Unbleached Parchment Paper on hand—it’s sturdy enough to withstand pressure without tearing.
For extra crispy edges, press the parchment against the pan’s sides before lifting.
Storage Containers
Store finished treats in an airtight container with parchment paper between layers to maintain crispness. I use Oxo Good Grips glass containers for short-term storage (5 days) and freezer-safe plastic bags** for longer storage (3 months).
Label them with the date—trust me, you’ll forget how long they’ve been sitting out! ❄️

Frequently asked questions
Can I make these treats without butterscotch chips?
Use 2 cups crushed toffee bits or 2 tablespoons butterscotch syrup instead. For extra depth, add 1 teaspoon butterscotch extract to the melted butter mixture. The texture will be slightly different but still delicious. If you're short on time, even 1 cup butterscotch-flavored candy melts will work in a pinch.
Why did my treats turn out too sticky? Overmixing the marshmallow mixture or not cooling it enough before cutting causes stickiness.
How can I make these treats look extra fancy?
For a restaurant-worthy finish, press the mixture into a greased loaf pan instead of a sheet pan, then cut into 1-inch slices. Roll the edges in crushed peppermint or pretzel bits before cooling, or drizzle with melted white chocolate. For a marbled effect, swirl in 1 cup crushed caramel candies before pressing into the pan. Store in clear containers for a bakery-style display.
Can I substitute regular marshmallows with mini marshmallows?
Yes, but you'll need 8 cups mini marshmallows instead of 6 cups large ones. Mini marshmallows melt faster, so watch the mixture closely—it may set up more quickly. For best results, use 1 teaspoon water to help them dissolve smoothly. The texture will be slightly softer but still delicious. If you're using mini marshmallows, reduce the cooking time by 30 seconds to avoid overmelting.
How do I store these treats for holidays or gifts?
For gift-giving, wrap individual squares in parchment paper, then place in cellophane bags tied with ribbon. Store in an airtight container at room temperature for up to 5 days. For longer storage, freeze the uncut sheet for 3 months. When ready to serve, thaw at room temperature for 30 minutes or reheat slices in the microwave for 10 seconds to restore that warm, gooey texture.
