Ingredients for butterscotch rice krispie squares
Creamy butterscotch layers and crispy cereal edges await with these carefully chosen ingredients.
| Ingredient | Amount | Notes |
|---|---|---|
| Butterscotch Chips 🍬 | 1 ½ cups | High-quality, premium brand preferred |
| Marshmallows 🍫 | 1 package | Mini marshmallows for even distribution |
| Unsalted Butter 🧈 | ½ cup | Cold, cut into small cubes |
| Rice Krispies Cereal 🍞 | 6 cups | Original flavor, not toasted |
| Heavy Cream 🥛 | ¼ cup | Full-fat for optimal texture |
| Vanilla Extract 🌿 | 1 tsp | Pure, high-quality extract |
| Salt 🧂 | ¼ tsp | Fine sea salt for balance |
| Butterscotch Extract 🍯 | ½ tsp | For enhanced flavor depth |
| Granulated Sugar 🍚 | ¼ cup | Fine granulation for smooth texture |

The butterscotch chips are the flavor foundation—Ghirardelli or Guittard brands deliver the richest caramel notes. Opt for mini marshmallows to ensure even distribution throughout the mixture, though standard marshmallows work in a pinch. Unsalted butter must be cold when added to prevent premature melting, so keep it chilled until ready to use. The Rice Krispies should be the original variety, not the toasted kind, to maintain that signature crunch. For the butterscotch depth, butterscotch extract is non-negotiable—it elevates the flavor beyond what chips alone can provide. If you're using dark chocolate chips, choose semi-sweet for balance.
No butterscotch extract? A pinch of cinnamon plus extra vanilla mimics the warmth, though the authentic flavor will differ. Substitute vegan marshmallows for a dairy-free version, but expect a slightly denser texture. Heavy cream can be swapped for half-and-half if needed, though the final product will be less luscious. For the powdered sugar dusting, confectioners' sugar is ideal, but granulated sugar finely pulsed in a blender works in a bind. The vanilla extract should be pure—imitation extracts lack the depth needed for this recipe. If you're customizing, white chocolate chips or caramel bits add delightful variations without overpowering the butterscotch.
Prevent the mixture from sticking by greasing the pan thoroughly with vegetable oil and dusting with powdered sugar before pressing. Store finished squares in an airtight container at room temperature for up to 5 days, though they're best enjoyed fresh. For longer storage, wrap individually in parchment and freeze for up to 3 months—thaw at room temperature before serving. The butterscotch chips and marshmallows should be used within 3 months of purchase for optimal flavor, while the butter and cream can be kept in the fridge for up to 6 months if unopened.

It’s the kind of treat that makes you feel like you’re indulging, but your wallet doesn’t even blink. Leftovers? They disappear faster than I can say “second helping.”
- Five-Ingredient Magic: I swear, this recipe is the kind of thing you’ll make just to prove it works—and then make again because it does.

No fancy techniques, no waiting around—just stir, press, chill.

Step-by-step instructions for butterscotch Rice Krispie squares
Mastering these squares means balancing creamy layers with crispy butterscotch—here's how to nail it every time.
Melt Butter, Cream, and Sugar for the Base
In a large saucepan, combine the 0.5 cup unsalted butter, 0.25 cup heavy cream, and 0.25 cup granulated sugar over medium-low heat. Stir occasionally until the butter melts completely and the mixture reaches a gentle simmer—you'll see tiny bubbles forming along the edges. This step is critical for creating the creamy foundation that binds everything together.
Once simmering, reduce heat to low and add the 1.5 cups butterscotch chips. Stir constantly until they're fully melted and the mixture becomes smooth and glossy. Remove from heat and whisk in the 1 tsp vanilla extract, 0.5 tsp butterscotch extract, and 0.25 tsp salt. This flavor infusion is what transforms ordinary Rice Krispie squares into something truly special. Let the mixture cool slightly—it should be warm but not hot when you add the marshmallows next.
Add Marshmallows and Chocolate for Depth
Working quickly, fold in the 1 package marshmallows using a wooden spoon or silicone spatula. Stir until fully melted and evenly distributed—you'll notice the mixture become thick and glossy. If you see any unmelted marshmallow bits, place the pan back over low heat for just 10-15 seconds to finish melting, then remove immediately to prevent scorching.
Next, gently fold in the 0.5 cup dark chocolate chips using the same utensil. The chocolate should melt into the mixture, creating pockets of rich, dark contrast against the butterscotch creaminess. If the chocolate doesn't melt completely, place the pan over low heat for 5-10 seconds while stirring constantly. The goal is a smooth, velvety sauce that coats the back of a spoon.
Grease the Pan and Assemble the Squares
While the filling cools slightly, grease a 9x13-inch baking dish thoroughly with 1 tbsp vegetable oil, ensuring the oil coats every corner. This prevents sticking and makes removal effortless later. Line the dish with parchment paper, leaving an overhang on two sides for easy lifting after baking.
Spread the butterscotch mixture evenly into the prepared dish, using a spatula to smooth the top. Then, gently press 6 cups Rice Krispies cereal into the mixture, working in small sections. Press down firmly but evenly—this creates the signature crispy texture while maintaining the creamy layers beneath. The cereal should cover the entire surface without gaps, forming a continuous layer that will hold its shape when cut.
Bake Until Set and Cool Completely
Bake at 350°F for 20-25 minutes, or until the edges are lightly golden and the center is set but still slightly soft. A toothpick inserted into the center should come out clean with just a few crumbs clinging to it—this indicates the perfect balance of crispiness and creaminess.
Remove from the oven and let the squares cool completely in the pan for at least 1 hour. This cooling period is essential—it allows the layers to fully set and prevents the squares from falling apart when sliced. Once cooled, lift the squares out using the parchment overhang, then cut into 16 equal squares with a sharp knife. Dust the top with 0.25 cup powdered sugar for a professional finish that adds sweetness and visual appeal.
Pro Tips For Making Butterscotch Rice Krispie Squares
- Chop Chips First: I learned this the hard way—melted butterscotch chips turn into a gloopy mess if you toss them in whole. Roughly chop them into quarter-inch pieces before melting so they distribute evenly and keep that perfect butterscotch crunch. (Yes, even if you’re impatient like me.)
- Melt Butter Slow: Crank the heat to medium-low for the butter and heavy cream mixture. High heat burns the cream before the butter melts, and you’ll end up with a bitter aftertaste. A gentle simmer keeps the base smooth and rich—no need to rush this part.
- Skip Overmixing Marshmallows: Once you fold in the marshmallows, stir just until they’re fully melted and the cereal is lightly coated. Overmixing makes the squares dense and chewy. Stop when it looks like wet sand—any more and you’ve ruined the texture.
- Press Firmly, Cool Slow: Press the mixture into the pan hard—don’t be shy, use your palm or a spatula. Then, let it cool at room temperature for 10 minutes before slicing. Cutting too soon means messy edges, and no one wants that. (Your future self will thank you.)
Creative variations of this dish
Caramelized Nut Version
Swap the butterscotch chips for 1.5 cups caramelized pecans or walnuts (toasted with brown sugar and butter) to add a toasty crunch. Use ½ cup caramel sauce (homemade or store-bought) instead of butterscotch chips, and fold in ½ cup chopped toasted nuts after melting the marshmallows.
This variation keeps the creamy texture while adding a sophisticated nutty depth. 🌰
White Chocolate Dream
Replace the butterscotch chips with 1.5 cups white chocolate chips and add ½ tsp almond extract to the flavor infusion. For extra indulgence, fold in ½ cup mini marshmallows and ½ cup crushed pretzels before pressing the Rice Krispies.
The result is a sweet, creamy dessert with a salty crunch that balances the richness. 🍫
Spiced Chai Twist
Infuse the cream base with 1 tsp chai spice blend (cinnamon, cardamom, ginger, cloves) while melting the butter. Use 1 cup butterscotch chips and ½ cup dried cranberries for tartness.
Add ¼ cup chopped candied ginger after pressing the cereal for a warm, spiced kick. This variation works beautifully during the holidays or for chai lovers. 🌶️
Vegan Butterscotch Delight
For a dairy-free version, use ½ cup vegan butter, ½ cup coconut cream, and 1 package vegan marshmallows. Melt the vegan butter with ½ cup coconut sugar and 1.5 cups butterscotch chips, then proceed as directed.
The coconut cream adds a subtle tropical note that pairs surprisingly well with butterscotch. 🌱
Boozy Butterscotch
Add 2 tbsp bourbon or butterscotch schnapps to the melted butterscotch mixture for an adult-friendly twist. Fold in ½ cup mini marshmallows and ½ cup chopped toasted pecans before pressing the Rice Krispies.
The alcohol enhances the caramel notes while adding a smooth warmth. Perfect for holiday parties or dessert courses. 🥃

Frequently asked questions
Can I make these without butterscotch chips?
Yes! For a similar flavor, melt 1.5 cups brown sugar with 2 tbsp water and 1 tbsp butter until it becomes a thick caramel. Let it cool slightly before mixing with marshmallows. Add ½ tsp vanilla and ¼ tsp cinnamon to enhance the butterscotch notes. The texture will be slightly different but still delicious!
Why did my squares fall apart when cutting?
This usually happens if the mixture wasn't fully cooled before cutting. Let the squares rest in the pan for at least 1 hour—this allows the cream to set properly. Also, ensure you pressed the Rice Krispies firmly into the butterscotch layer. If they still crumble, chill the pan in the fridge for 15-20 minutes before cutting.
How can I make these vegan?
Use ½ cup vegan butter, ½ cup coconut cream, and 1 package vegan marshmallows instead of dairy versions. Melt the vegan butter with ½ cup coconut sugar and 1.5 cups butterscotch chips (ensure they're vegan-friendly). The texture will be slightly denser but still tasty. For extra richness, add 1 tbsp coconut oil to the mixture.
Can I use toasted Rice Krispies instead?
Not recommended! Toasted Rice Krispies are much harder and won't absorb the butterscotch mixture as well, leading to a dry, crumbly texture. Stick with the original cereal for that perfect crispy-yet-tender contrast. If you love toasted cereal, try this recipe with cornflakes instead—they hold up better to the creamy filling.
How long will these stay fresh?
Store in an airtight container at room temperature for up to 5 days. For longer storage, wrap individually in plastic wrap and freeze for up to 3 months. Thaw at room temperature for 1-2 hours before serving. The butterscotch flavor intensifies slightly after a day or two, so they often taste even better the next day!
