Ingredients
For the Cupcakes
- 1½ cups all-purpose flour
- 1½ teaspoons baking powder
- ¼ teaspoon salt
- ½ cup unsalted butter, softened
- ¾ cup granulated sugar
- 2 large eggs
- 2 teaspoons vanilla extract
- ½ cup milk
For the Marshmallow Filling
- 1 cup marshmallow fluff or marshmallow cream
- 2 tablespoons unsalted butter, softened
- ½ cup powdered sugar
- ½ teaspoon vanilla extract
For Decoration
- ½ cup melted chocolate, optional
- Mini marshmallows, optional
- Sprinkles, optional
The cupcake batter is designed to produce a soft crumb that can support the filling without becoming heavy. The marshmallow mixture provides the sweet, creamy center, while the optional chocolate or sprinkles give the finished cupcakes an easy decorative touch.
Preparing the Cupcake Batter
Get the Pan Ready
Preheat the oven to 350°F (175°C).
Line a 12-cup muffin pan with paper cupcake liners. Having the pan ready before mixing the batter helps you move efficiently once the ingredients are combined.
Combine the Dry Ingredients
Whisk the flour, baking powder, and salt together in a medium bowl.
Breaking up any lumps at this stage helps the dry ingredients distribute evenly throughout the batter.
Cream the Butter and Sugar
Place the softened butter and granulated sugar in a large mixing bowl.
Beat for approximately 2–3 minutes, until the mixture looks lighter and creamy.
The butter should be softened rather than melted. Melted butter changes the structure of the batter and can produce a different crumb.
Add the Eggs and Vanilla
Add the eggs one at a time, mixing after each addition.
Add the vanilla and mix briefly until incorporated.
If the mixture looks slightly uneven at this point, that’s not necessarily a problem. The flour and milk will bring the batter together.
Bring the Batter Together
Add the dry ingredients in portions, alternating with the milk.
Begin and finish with the dry ingredients. Mix on low speed or fold with a spatula just until the batter is combined.
Avoid prolonged mixing after the flour has been added. Overmixing can develop gluten and make the cupcakes less tender.
Fill the Cupcake Liners
Divide the batter evenly between the 12 liners, filling each approximately two-thirds full.
Try to keep the portions similar in size so the cupcakes finish baking at roughly the same time.
Baking for a Soft, Even Crumb
Place the pan in the center of the preheated oven and bake for approximately 18–22 minutes.
The cupcakes should look lightly golden and spring back when gently touched in the center. A toothpick inserted into the cake portion should come out clean or with a few moist crumbs.
Avoid opening the oven repeatedly during the first part of baking because a sudden temperature change can interfere with the cupcakes’ rise.
Once baked, leave the cupcakes in the pan for about 5 minutes, then transfer them to a wire rack to cool completely.
Don’t fill the cupcakes while they’re warm. Heat can soften the marshmallow filling too much and make it difficult to keep inside the cake.
Making the Marshmallow Filling
Create the Creamy Base
Place the softened butter in a mixing bowl and beat until smooth.
Add the powdered sugar gradually, mixing until the mixture becomes creamy.
Blend in the Marshmallow
Add the marshmallow fluff and vanilla extract.
Beat on low speed at first, then increase slightly until the filling becomes smooth and evenly combined.
The finished filling should be thick enough to hold its shape but soft enough to pipe or spoon into the cupcakes.
Adjust the Consistency
If the filling feels too soft, add a little more powdered sugar.
If it seems excessively thick, mix in a very small amount of milk.
Make adjustments gradually. A small change in liquid or powdered sugar can noticeably affect the consistency.
Keep It Ready for Filling
Transfer the filling to a piping bag fitted with a round tip. If you don’t have a piping bag, a small spoon works too.
Keep the filling covered while you prepare the cupcakes so the surface doesn’t dry out.
Filling the Cupcakes
Once the cupcakes are completely cool, use a small paring knife or cupcake corer to remove a small portion from the center of each cupcake.
Don’t cut all the way to the bottom. You only need enough space to hold a spoonful of marshmallow filling.
Pipe or spoon the filling into the center.
You can replace a small piece of the removed cake over the opening, although this isn’t necessary if you’re planning to frost or decorate the cupcakes.
For an especially generous marshmallow center, fill until the mixture reaches just below the top of the cupcake.
Finishing the Cupcakes
Marshmallow Frosting
For a simple finish, pipe a little additional marshmallow filling over the top of each cupcake.
A large round piping tip creates a soft, cloud-like appearance, while a star tip gives the cupcakes more definition.
Chocolate Drizzle
Melt chocolate and allow it to cool slightly before drizzling it over the cupcakes.
Chocolate provides a useful contrast to the sweet marshmallow filling and works especially well with vanilla cupcakes. If you enjoy the chocolate and-marshmallow combination, superb marshmallow brownies are another rich dessert worth trying.
Toasted Marshmallow Finish
Place a few mini marshmallows on top and lightly toast them using a suitable kitchen torch.
Work carefully and keep the flame moving rather than holding it in one place. Marshmallows can brown quickly.
Simple Sprinkles
Add sprinkles while the frosting is still soft so they adhere to the surface.
Choose colors that match the occasion for an easy birthday or holiday presentation.
How to Keep the Cupcakes Moist
Measure Flour Accurately
Too much flour can produce a dense or dry cupcake. For consistent results, spoon flour into a measuring cup and level it rather than packing it down.
Don’t Overbake
Cupcakes continue to firm as they cool, so baking them well beyond the point of doneness can leave the crumb dry.
Don’t Overmix
Once the flour has been incorporated, stop mixing. A few small lumps are preferable to developing too much gluten.
Cool Before Filling
Warm cupcakes can soften the marshmallow filling and make the center difficult to control. Complete cooling gives you a cleaner filling process.
Store Them Properly
Once filled and decorated, keep the cupcakes covered to protect the crumb from drying out.
Common Problems and Fixes
Why Did My Cupcakes Sink?
Cupcakes can sink when the batter is overmixed, the oven temperature is incorrect, or the cakes are removed before they’re fully baked.
Make sure the oven is properly preheated and avoid opening the door repeatedly during baking.
Why Is the Filling Leaking?
The cavity may have been cut too deeply, or the filling may be too soft.
Make a modest opening in the center and adjust the filling consistency before piping.
Why Are My Cupcakes Dry?
Overbaking and excess flour are common causes. Check the cupcakes near the beginning of the suggested baking range and remove them when a toothpick shows a few moist crumbs.
Why Is the Marshmallow Filling Too Runny?
If the filling is too soft to pipe, mix in a little additional powdered sugar and chill it briefly before filling the cupcakes.
Why Is the Frosting Difficult to Pipe?
The filling may be too cold or too thick. Let it sit for a few minutes at room temperature and mix briefly before transferring it to the piping bag.
Storage
Store filled cupcakes in an airtight container.
If the room is warm or the cupcakes contain a topping that needs refrigeration, refrigerate them and allow them to sit at room temperature briefly before serving so the cake can soften.
For the best texture, keep the cupcakes protected from air. An uncovered cupcake can lose moisture quickly, particularly around the cut center used for the filling.
If you’re preparing them ahead for an event, bake and cool the cupcakes first, then fill and decorate them closer to serving time.
Frequently Asked Questions
Can I use marshmallow fluff as cupcake filling?
Yes. Marshmallow fluff works well as a cupcake filling because its soft consistency makes it easy to pipe into a small cavity in the center of the cake.
Can I use marshmallow cream instead?
Yes. Marshmallow cream can be used in a similar way. Different brands may have slightly different consistencies, so you may need a small adjustment with powdered sugar.
Can I make these cupcakes ahead?
Yes. The cupcakes can be baked ahead and stored covered. Fill and decorate them closer to serving when possible for the best texture and appearance.
Can I freeze the cupcakes?
The unfilled cupcakes can generally be frozen more easily than fully decorated cupcakes. Wrap cooled cupcakes securely and thaw them before adding the marshmallow filling.
How do I get a toasted marshmallow topping?
Add mini marshmallows to the top of the cupcakes and carefully toast them with a kitchen torch. Keep the flame moving to prevent the surface from burning.
Can I make chocolate marshmallow cupcakes?
Yes. Replace a portion of the flour with unsweetened cocoa powder to create a chocolate cupcake base, then keep the marshmallow filling and chocolate topping.
Final Thoughts
This marshmallow cupcake recipe combines a tender homemade cupcake with a soft, sweet marshmallow center. The filling gives the cupcakes an unexpected texture without requiring complicated pastry techniques, while chocolate, sprinkles, or toasted marshmallows can give them a more finished appearance.
For the best result, avoid overmixing the batter, bake the cupcakes only until they are properly set, and let them cool completely before adding the marshmallow filling. Once the basic recipe is familiar, you can easily adapt it into chocolate, birthday, or holiday versions.
