Ingredients for cake batter rice crispy treats
Nine essential ingredients transform classic Rice Krispies into decadent cake-flavored no-bake treats.
| Ingredient | Amount | Notes |
|---|---|---|
| Boxed Vanilla Cake Mix 🍰 | 1 box | Dry mix, any flavor preferred |
| Large Marshmallows 🍫 | 10 oz | Mini marshmallows for smaller treats |
| Rice Krispies Cereal 🍚 | 6 cups | Original flavor preferred |
| Unsalted Butter 🧈 | ½ cup | Cut into small cubes for melting |
| Vanilla Extract 🍮 | 1 tsp | Pure, high-quality preferred |
| Granulated White Sugar 🍚 | ¼ cup | For added sweetness |
| Large Eggs 🥚 | 2 whole | Room temperature preferred |
| Vegetable Oil 🫒 | ⅓ cup | Light, neutral-flavored preferred |
| Milk 🥛 | ½ cup | Whole milk for creaminess |
| Salt 🧂 | ½ tsp | Diamond Crystal preferred |
| Baking Powder 🍞 | 1 tsp | For proper leavening |
| Vanilla Ice Cream 🍦 | ½ cup | Optional for extra richness |
The cake mix is the star here, so choose a high-quality boxed mix—the better the batter, the more pronounced the flavor. Betty Crocker or Duncan Hines work perfectly, but avoid mixes with added oil or eggs since we're making our own batter. The marshmallows should be fresh and plump—check the expiration date, as stale marshmallows lose their melt and stickiness. For the butter, unsalted is a must to control the seasoning, and cutting it into small cubes ensures even melting. Stock up on Rice Krispies in bulk if you're making these often—they're a pantry staple that keeps indefinitely.
No cake mix? Make your own batter with 1 cup flour, 0.5 cup sugar, 0.5 tsp baking powder, 0.25 tsp salt, 0.25 cup oil, 0.5 cup milk, and 1 egg—just mix and fold into the marshmallow mixture. Short on marshmallows? Substitute with fluffed rice cereal, though the texture will differ slightly. The vanilla ice cream is optional but adds a luxurious creaminess—Häagen-Dazs or Ben & Jerry's brands work best for that rich flavor. If you're avoiding dairy, use coconut milk or vegan butter instead, though the treats will be slightly less rich. Always measure your baking powder and salt precisely—these control the texture and flavor balance.
Store finished treats in an airtight container at room temperature for up to 5 days—they stay crispy if sealed properly. For longer storage, freeze portions for up to 3 months—just thaw at room temperature before serving. These treats reheat beautifully in the microwave for 10-15 seconds to restore crispiness. Portion into individual bags for easy grab-and-go snacks, or shape into festive shapes for parties. The cake flavor intensifies slightly after sitting overnight, making them even more irresistible the next day.

Step-by-step instructions for cake batter rice crispy treats
Transform simple ingredients into decadent, cake-flavored treats with this foolproof method.
🍳 Step 1: Melt Butter and Prepare Cake Batter Mixture
In a large microwave-safe bowl, melt the 0.5 cup unsalted butter in 30-second intervals, stirring between each, until completely liquid. Let it cool slightly for 2 minutes—it should be warm to the touch but not hot. This prevents scrambling the eggs later.
In a separate mixing bowl, whisk together the 1 box boxed vanilla cake mix, 0.25 cup granulated white sugar, 1 tsp vanilla extract, 1 tsp baking powder, and 0.5 tsp salt. Add the 2 whole large eggs, 0.33 cup vegetable oil, and 0.5 cup milk, mixing until the batter is smooth and fully combined. The mixture should resemble thick cake batter with no dry spots remaining.
🍳 Step 2: Combine and Melt Marshmallows
Pour the melted butter into the cake batter mixture and stir until fully incorporated. The batter will become slightly thinner but should still hold its shape when spooned. Add the 10 oz large marshmallows and fold them gently with a spatula—this prevents overmixing and keeps the marshmallows intact.
Transfer the mixture to a large microwave-safe bowl. Microwave in 30-second bursts, stirring vigorously after each interval, until the marshmallows are completely melted and the mixture is smooth. You'll know it's ready when the mixture looks glossy and homogenous, with no visible marshmallow chunks. This typically takes 2-3 minutes total.
👨🍳 Step 3: Fold in Rice Krispies and Optional Ice Cream
Remove the melted mixture from the microwave and let it cool for 1 minute. Using a silicone spatula, gently fold in the 6 cups rice krispies cereal until evenly distributed. Work quickly but carefully—rice krispies absorb moisture rapidly. The mixture should be thick enough to hold its shape when pressed but still pliable.
For extra richness, fold in the 0.5 cup vanilla ice cream last. The ice cream will create pockets of creamy surprise in each bite. If the mixture seems too sticky, let it sit for 1 minute to firm up slightly before proceeding. The texture should resemble wet sand that holds together when pressed.
🥘 Step 4: Assemble and Press into Pan
Lightly grease a 9x13-inch baking dish with butter or cooking spray. Using a spatula, press the rice krispy mixture firmly into the pan, creating an even layer. For crispier edges, press the mixture against the sides of the pan as well. The treats should be compact but not overly dense—think of it like packing snow into a snowball.
Smooth the top with the back of a spoon and let the treats set in the pan for 1 hour at room temperature. This resting period allows the mixture to firm up and makes slicing much easier. For a firmer texture, you can refrigerate for 30 minutes instead, but room temperature works perfectly for this recipe.
⏰ Step 5: Chill and Slice for Perfect Texture
Once set, remove the treats from the pan and cut into squares or rectangles using a sharp knife. For cleaner cuts, dip the knife in hot water and wipe it dry between slices. The treats should hold their shape when lifted but still be soft enough to enjoy immediately.
For best results, chill the treats in the refrigerator for 1 hour before serving. This enhances the crispiness of the rice krispies while keeping the cake batter center moist. Store leftovers in an airtight container at room temperature for up to 3 days, though they rarely last that long!
Pro Tips For Making Cake Batter Rice Crispy Treats
- MELT MARSHMALLOWS LOW AND SLOW: I learned this the hard way—blasting marshmallows on high turns them into sticky goo instead of smooth, glossy strands. Use medium-low heat and stir constantly, breaking them into smaller pieces first. If they start browning too fast, pull the pan off for a minute and let them cool slightly.
- USE LESS BUTTER THAN YOU THINK: Unsalted butter adds richness, but too much makes the treats greasy and heavy. Stick to ½ cup (1 stick) max—this recipe doesn’t need extra fat to bind. If your cake mix calls for oil, skip it entirely; the butter’s job is flavor, not structure.
- STOP STIRRING BEFORE THE CRISPS FORM: I used to keep mixing until the last second, but that’s when you get lumpy, uneven treats. Once the marshmallow-butter mix starts thickening and pulling away from the pan’s edges, stop stirring. Let the cereal clump naturally—it’ll distribute better when you fold it in.
- TOAST THE CRISPS FIRST: This isn’t the prettiest method, but it’s the tastiest: Spread the Rice Krispies on a baking sheet and toast them at 300°F (150°C) for 3–5 minutes until they’re just slightly darker and smell toasty. The extra crunch makes a real difference, especially if you’re using store-bought cereal that’s gone soft. (Yes, even if you’re impatient like me.)
Make-ahead tips for cake batter rice crispy treats
Prep Ahead Strategy
Make the batter mixture up to 24 hours in advance and store it in an airtight container in the fridge. The flavors meld beautifully overnight, and you can simply melt the marshmallows fresh when ready.
I always prep the batter the night before—it saves time and makes assembly a breeze the next day. 💫
Freezer-Friendly Assembly
Press the treats into the pan as directed, then wrap the entire pan tightly in plastic wrap and aluminum foil. Freeze for up to 3 months—this works especially well for holiday gifting.
Thaw at room temperature for 1-2 hours before slicing. The texture stays perfect, and the cake flavor intensifies after freezing.
Portion Control Tips
Divide the melted marshmallow mixture into two microwave-safe bowls before adding the Rice Krispies. This makes folding easier and prevents overmixing. I like to portion the batter and marshmallows separately so I can adjust sweetness or add-ins (like chocolate chips) to different batches. 🍫
Make-Ahead Garnishes
Prep any toppings or garnishes in advance—think chopped nuts, sprinkles, or chocolate drizzle. Store them in small containers near your treats assembly station. This keeps your workspace organized and makes decorating quick. I often toast pecans ahead of time for a crunchy topping.
Reheating Leftovers
For treats that have lost crispiness, reheat individual pieces in the microwave for 5-10 seconds on high power. The heat reactivates the marshmallow's stickiness, restoring that classic Rice Krispy texture.
For a stovetop method, place treats on a wire rack over simmering water for 1-2 minutes—this creates steam that crisps them up beautifully.
Party Platter Prep
Cut treats into festive shapes using cookie cutters before serving. Arrange them on a platter with powdered sugar dusting or colored sprinkles for a showstopping presentation. I always prep these the day before parties—they stay fresh and look impressive when served. 🎉

Frequently asked questions
Why do these treats have a cake flavor but still taste like Rice Krispy Treats?
The cake batter adds subtle depth while the marshmallows and Rice Krispies maintain the classic texture. The key is balancing the cake mix (1 box) with the marshmallows (10 oz)—this ratio ensures the familiar sweetness remains dominant while adding that unexpected cake note. Think of it like a flavor fusion!
Can I make these treats without a microwave?
Yes! Melt the butter and marshmallows in a heavy-bottomed saucepan over low heat, stirring constantly until smooth. For the cake batter, mix it separately and combine with the melted mixture off the heat. The texture may take 2-3 extra minutes to set, but the flavors stay identical.
How do I prevent the treats from getting too sticky?
Work quickly when folding in Rice Krispies—they absorb moisture fast. Let the marshmallow mixture cool for 1-2 minutes before adding them, and press the treats firmly into the pan. If they're still too soft, chill for 30 minutes before slicing. The cake batter helps bind everything together!
What's the best way to store these for maximum crispiness?
Store in an airtight container at room temperature for up to 5 days. For longer storage, freeze portions for 3 months. To restore crispiness, microwave individual pieces for 5-10 seconds or place on a wire rack over simmering water for 1-2 minutes.
Can I add mix-ins like chocolate chips or nuts?
Fold in ½ cup chocolate chips or ½ cup chopped nuts with the Rice Krispies. For best results, use mini chocolate chips—they melt evenly. Toast nuts first for extra flavor! Just be gentle when folding to keep the treats from breaking apart.
