Essential Ingredients for the Cupcakes
To create the perfect vanilla cupcakes, you’ll need all-purpose flour, sugar, eggs, and baking powder. These staples provide the structure and sweetness necessary for a classic cupcake base. Additionally, a touch of vanilla extract enhances the flavor, while whole milk and butter add moisture and richness.

Pro Tips
Baking perfect marshmallow cupcakes requires a few insider tips. These suggestions will ensure your cupcakes turn out fluffy and delicious every time.
- Use room temperature ingredients: Ensure butter and eggs are at room temperature before mixing. This helps achieve a smoother batter.
- Do not overmix: When combining the dry and wet ingredients, mix until just combined to maintain the cupcakes’ light texture.
- Fill cupcake liners properly: To ensure even baking, fill each liner about two-thirds full.
- Monitor baking time: Check the cupcakes a few minutes before the recommended baking time to prevent overbaking.
The most crucial tip is to let the cupcakes cool completely before applying the frosting. This prevents the frosting from melting and ensures a beautiful presentation.
Step-by-Step Instructions
Preparing the Cupcake Batter
Start by preheating your oven to 350°F (175°C) and lining a cupcake pan with paper liners. In a large mixing bowl, cream together the butter and sugar until light and fluffy. Add in the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.
In a separate bowl, whisk together the flour and baking powder. Gradually add the dry ingredients to the wet mixture, alternating with the milk. Mix just until combined to avoid overmixing.
Baking to Perfection
Divide the batter evenly among the cupcake liners, filling each about two-thirds full. Bake in the preheated oven for 18-20 minutes, or until a toothpick inserted into the center comes out clean. Once baked, remove from the oven and let cool in the pan for 5 minutes before transferring to a wire rack to cool completely.

Frosting and Decorating Tips
While the cupcakes cool, prepare the marshmallow frosting. In a mixing bowl, beat the butter until creamy. Gradually add confectioners’ sugar and mix until fully incorporated. Add marshmallow fluff and vanilla extract, then beat until smooth and fluffy.
Once the cupcakes are completely cooled, use a piping bag to frost each cupcake with the marshmallow frosting. Decorate with sprinkles or mini marshmallows for an extra touch.
