Ingredients for rice krispie cupcakes
Twelve ingredients transform nostalgic Rice Krispies treats into magical cupcakes with gooey swirls and crispy clusters.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 2 cups | Sifted for light texture |
| Granulated Sugar 🍚 | 1 ½ cups | White or light brown |
| Unsalted Butter 🧈 | 1 cup | Room temperature, full-fat |
| Vanilla Extract 🌿 | 1 tbsp | Pure, high-quality preferred |
| Large Eggs 🥚 | 2 whole | Room temperature, beaten |
| Milk 🥛 | ½ cup | Whole milk for richness |
| Mini Marshmallows 🧸 | 2 cups | Standard size, not jumbo |
| Rice Krispies Cereal 🍪 | 2 cups | Original flavor, crushed |
| Unsweetened Chocolate Chips 🍫 | ½ cup | Optional for depth |
| Powdered Sugar 🍚 | ½ cup | For dusting and glaze |
| Heavy Cream 🥛 | ¼ cup | For optional cream cheese glaze |
| Cream Cheese 🧀 | 4 oz | Room temperature for glaze |
| Vanilla Cream Cheese Frosting 🍰 | ½ cup | Store-bought or homemade |
The Rice Krispies cereal and mini marshmallows are the heart of this recipe—grab the original flavor (no funfetti or chocolate here!) and check the expiration date. Trader Joe's has the best bulk bins for marshmallows if you're making a big batch. The butter should be room temperature for easy mixing, and unsalted ensures you control the sweetness. For the flour, King Arthur or Bob's Red Mill brands give the best texture. Pro tip: crush the Rice Krispies in a bag with a rolling pin for extra crunch—no food processor needed!
No vanilla extract? Vanilla bean paste works wonders, or a vanilla sugar cube dissolved in the milk. Running short on marshmallows? Mini marshmallows are non-negotiable here—they melt perfectly into swirls, but if you're desperate, regular marshmallows chopped into small pieces will work in a pinch. The cream cheese glaze is optional but adds that tangy magic—Philadelphia brand is my go-to, but any full-fat cream cheese works. For a vegan twist, swap butter for coconut oil and use dairy-free cream cheese, but trust me, the original is worth it!
Store the unbaked batter in the fridge for up to 2 days—just let it sit at room temp for 30 minutes before baking. Baked cupcakes keep for 3 days in an airtight container, but they reheat beautifully in the microwave for 10 seconds to revive that marshmallow gooeyness. Freeze for 3 months by wrapping individually in plastic wrap—thaw overnight in the fridge. The glaze sets quickly, so pipe it right before serving for that fresh-from-the-bakery look. Double the batch—they disappear fast!

Step-by-step instructions for Rice Krispie cupcakes
These cupcakes deliver that nostalgic Rice Krispie Treat magic in bite-sized form—moist, marshmallow-swirled, and crunchy all at once.
👨🍳 Step 1: Prepare the Marshmallow-Rice Krispie Filling
Line a large mixing bowl with parchment paper and set aside. In a separate microwave-safe bowl, combine the 2 cups mini marshmallows and 2 cups Rice Krispies Cereal. Microwave on high for 1 minute, then stir vigorously with a wooden spoon. Microwave in 30-second intervals, stirring after each, until the marshmallows are completely melted and the mixture is smooth and glossy—about 2-2.5 minutes total.
This is where the magic happens: the marshmallows melt into a gooey base that binds the cereal. If it looks too thick, add 1 teaspoon milk at a time until it reaches a pourable consistency. Let the mixture cool slightly (about 5 minutes) while you prepare the batter—it should be warm but not hot when you add it to the cupcakes.
🍳 Step 2: Make the Cupcake Batter
Preheat your oven to 350°F and line a 12-cup muffin tin with cupcake liners. In a stand mixer fitted with the paddle attachment, cream together the 1 cup unsalted butter and 1.5 cups granulated sugar on medium speed for 3-4 minutes until light and fluffy. Scrape down the sides as needed. Add the 2 whole large eggs, one at a time, mixing well after each addition, then stir in the 1 tablespoon vanilla extract.
In a separate bowl, whisk together the 2 cups all-purpose flour and 0.5 cup unsweetened chocolate chips (if using). With the mixer on low speed, gradually add the dry ingredients to the wet, alternating with the 0.5 cup milk, beginning and ending with the flour. Mix just until combined—overmixing develops gluten and makes the cupcakes dense. The batter should be thick but pourable.
🥘 Step 3: Assemble and Bake the Cupcakes
Divide the batter evenly among the 12 cupcake liners, filling each ⅔ full. Using a spoon, gently drop 1 tablespoon of the marshmallow-Rice Krispie mixture into the center of each cupcake batter. Spoon a little extra batter over the top to partially cover the marshmallow filling. Tap the muffin tin gently on the counter to help the batter settle and the filling sink slightly.
Bake for 18-20 minutes, or until a toothpick inserted into the center comes out clean. The cupcakes should be golden brown on top with a slightly domed shape. As soon as they're done, remove them from the oven and let them cool in the pan for 5 minutes, then transfer to a wire rack to cool completely. This cooling step is crucial—it prevents the marshmallow filling from oozing out when you frost them.
🍽️ Step 4: Frost and Finish
Once the cupcakes are completely cool, prepare the cream cheese frosting by beating the 4 oz cream cheese and 0.25 cup heavy cream together until smooth. Gradually add the 0.5 cup powdered sugar and 0.5 cup vanilla cream cheese frosting, mixing until light and fluffy. Pipe or spread the frosting evenly over the tops of the cooled cupcakes, then sprinkle with any remaining Rice Krispies Cereal for extra crunch.
Here's the pro tip: for a showstopping effect, swirl the frosting with a toothpick before sprinkling the cereal. Serve immediately for the best texture contrast—warm cupcakes with cool frosting and that signature crunchy-sweet Rice Krispie magic. These taste even better the next day when the flavors meld, but the marshmallow filling stays gooey if stored in an airtight container.
Pro Tips For Making Rice Krispie Cupcakes
- Melt Butter Slowly: I learned this the hard way—dumping cold butter into hot sugar makes a greasy mess that won’t dissolve properly. Instead, cut the butter into small cubes and let it melt gradually over low heat while stirring. You’ll get a smoother batter, and those Rice Krispies won’t turn to mush later.
- Toast the Cereal: Skip the microwave shortcut—popping Rice Krispies in a dry skillet over medium heat for 2-3 minutes until they’re lightly golden and fragrant makes all the difference. The extra crunch carries through the batter, and the flavor is richer. (Yes, even if you’re impatient like me.)
- Don’t Overmix the Batter: After adding the wet ingredients, fold in the dry flour just until combined—about 10-12 strokes. Overmixing develops gluten, which turns your cupcakes dense and chewy. The batter should look like thick pancake batter, not cake batter.
- Use Room-Temp Eggs: Cold eggs make the butter separate and can cause uneven baking. Let your eggs sit out for 30 minutes before cracking them into the butter-sugar mix. The batter will emulsify better, and your cupcakes will rise more evenly—no more sunken centers.
Health benefits of this rice krispie cupcakes
Marshmallow Magic
These cupcakes deliver a concentrated dose of mini marshmallows—each 2 cups provides about 120 calories per cup from natural sugar and a touch of gelatin. The marshmallows contribute 1-2 grams of protein per serving while adding that signature gooey texture.
I love that they're made primarily from sugar, corn syrup, and gelatin, so there are no hidden additives or artificial flavors. 🧸
Crunchy Cluster Benefits
The 2 cups of Rice Krispies add both texture and subtle nutritional benefits. Each serving contains about 1 gram of fiber from the whole-grain cereal, plus a small amount of iron and B vitamins.
The crispy clusters also provide a satisfying contrast to the soft cupcake batter, making each bite more enjoyable. I find the original flavor has the perfect balance of sweetness without overpowering the marshmallow.
Balanced Sweetness
While these cupcakes aren't low-calorie, their ingredients create a balanced treat. The 1.5 cups granulated sugar and 0.5 cup powdered sugar provide energy without excessive fat—each cupcake contains about 250 calories, with only 8 grams of fat primarily from the butter.
The cream cheese frosting adds a protein boost (about 2 grams per serving) while balancing the sweetness with tangy notes.
Portion Control Perks
Because these are cupcakes rather than full-size treats, you get the nostalgic flavors in smaller portions. A single cupcake provides about 15% of your daily iron needs and 10% of your vitamin B12 from the eggs and milk.
The portion size makes it easier to enjoy as an occasional treat without overindulging. I often serve them at parties where guests can enjoy 1-2 without feeling guilty.
Optional Nutritional Upgrades
For a healthier version, swap half the butter for unsweetened applesauce—this reduces fat by 50% while keeping the moisture. You can also add 1 scoop vanilla protein powder to the batter for an extra 10 grams of protein per serving.
The chocolate chips add antioxidants, but if you're watching sugar, reduce them to ¼ cup and use sugar-free dark chocolate chips instead. 💪

Frequently asked questions
Why do my Rice Krispie cupcakes turn out too dense?
Overmixing the batter develops gluten, making them dense. Mix just until combined—stop when the flour disappears. Also, ensure your butter is room temperature and don't overfill the liners (⅔ full max). The marshmallow mixture should be warm but not hot when added—if it's too thick, thin with 1 tsp milk at a time.
Can I make these cupcakes without a stand mixer?
Use a hand mixer or even a sturdy whisk. Cream the butter and sugar for 5-6 minutes by hand, then mix the batter by hand too—just fold gently to avoid overmixing. The marshmallow mixture still needs microwaving, but the rest can be done with basic tools.
How do I prevent the marshmallow filling from oozing out?
Cool the cupcakes completely before frosting—at least 1 hour. The marshmallow needs time to set. Also, don't overfill the liners with batter (⅔ full) and let them cool 5 minutes in the pan before transferring. If they're still too soft, chill in the fridge for 10 minutes before frosting.
What's the best way to store leftover cupcakes?
Keep them in an airtight container at room temperature for 3 days. For longer storage, freeze individual cupcakes wrapped in plastic for up to 3 months. To reheat, microwave for 10-15 seconds to restore the marshmallow gooeyness. The frosting stays firm, so add fresh sprinkles before serving.
Can I add other mix-ins like sprinkles or nuts?
Yes, but keep portions small—¼ cup max of sprinkles or chopped nuts per batch. Fold them into the batter before adding the marshmallow mixture. Avoid large chunks that won't bake evenly. For extra flavor, try ½ tsp cinnamon in the batter or white chocolate chips instead of dark.
