What are dulce de leche banana cupcakes?

Dulce de leche banana cupcakes combine classic banana cake with a caramel-like center and a chocolate cream topping. Ripe bananas give the cake a moist, tender crumb while a spoonful of dulce de leche in the middle adds a sweet, toffee-like surprise. A light milk chocolate whipped cream or frosting provides a smooth contrast and rounds out the flavors.

What is dulce de leche?

Dulce de leche is a sweet, caramel-like spread made by slowly cooking sweetened condensed milk until it becomes thick and golden. It is widely used in Latin American desserts as both a filling and a topping. Store-bought dulce de leche is convenient and typically thicker than homemade versions, but you can make your own if you prefer.

Ingredients

Refer to the recipe card below for detailed quantities and a printable ingredient list.

• All-purpose flour — the base for the cupcake crumb.
• Baking soda and baking powder — both provide lift for a light texture.
• Salt — balances and enhances the flavors.
• Unsalted butter, softened to room temperature.
• Granulated sugar (or caster sugar) for sweetness.
• Eggs — an extra-large egg plus an extra-large yolk help bind and enrich the batter.
• Whole milk — adds moisture and structure.
• Lemon juice — brightens the banana flavor and balances sweetness.
• Ripe bananas — mashed; the riper the better for sweetness and aroma.
• Whipping cream (≥30% fat) — for the milk chocolate whipped cream.
• Milk chocolate — melts into the cream for a smooth chocolate topping; substitute dark chocolate if you prefer a less sweet finish.
• Dulce de leche — store-bought or homemade, used to fill the centers.

How to make dulce de leche banana cupcakes

1. Prepare the chocolate cream the day before: Bring the whipping cream to a simmer and pour it over finely chopped milk chocolate. Stir until smooth, cover with plastic wrap directly on the surface, and refrigerate overnight so it sets and can be whipped the next day.
2. Make the cupcake batter: Preheat the oven to 335°F (170°C). Beat softened butter until creamy, then add sugar, the whole egg and extra yolk and mix until combined. Whisk together dry ingredients (flour, baking soda, baking powder, and salt) and add them to the butter mixture.
3. Add mashed ripe banana, lemon juice, and milk. Fold gently just until combined to keep the crumb tender.
4. Line a muffin pan with liners and fill each cup about two-thirds full. Bake for about 25 minutes, or until a toothpick inserted near the center comes out clean. Let cupcakes cool completely.
5. Assemble the next day for best results: Trim the tops if desired and use a corer or small knife to remove the centers. Spoon or pipe a small amount of dulce de leche into each cavity and optionally top with a thin slice of banana.
6. Whip the chilled chocolate cream to firm peaks, transfer to a pastry bag fitted with your favorite tip, and pipe generous swirls on top of each cupcake just before serving.

Expert tips

• Use very ripe bananas: the browner and spotty they are, the more banana flavor and natural sweetness you’ll get.
• Room-temperature ingredients: allow butter, eggs, and milk to come to room temperature for a smoother batter.
• Don’t overmix: fold the banana and liquid in only until incorporated to keep the cupcakes tender.
• Chocolate options: swap milk chocolate for dark chocolate if you prefer a less sweet topping.
• Neat filling: use a corer and a pastry bag for tidy centers and clean piping.
• Decorate on serving day: pipe the whipped cream just before serving for the best texture and appearance.
• Store dulce de leche carefully: refrigerated leftovers keep up to four weeks or can be frozen for up to two months.

Recipe variations

• Banoffee cupcakes: increase the dulce de leche filling and finish with a banana slice for a banoffee-inspired treat.
• Cream cheese chocolate frosting: blend cream cheese with melted chocolate for a richer, tangy topping.
• Peanut butter twist: add a small spoon of peanut butter with the dulce de leche for a nutty contrast.
• Salted caramel: sprinkle flaky sea salt over the dulce de leche to cut the sweetness.
• Darker chocolate: use dark chocolate in the whipped cream for deeper cocoa notes.

Storing & freezing

Store frosted cupcakes in an airtight container in the refrigerator for up to 3 days; allow them to come to room temperature before serving so the cake softens. Unfrosted cupcakes can sit at room temperature, covered, for a couple of days.

To freeze, wrap unfrosted and unfilled cupcakes individually in plastic wrap, place them in an airtight container, and freeze for up to 3 months. Thaw at room temperature, then fill and frost just before serving.

Recipe FAQ

What bananas are best for banana cupcakes?
Very ripe or overripe bananas with brown, spotty skins are best: they are sweeter, softer, and provide the strongest banana flavor.

How can I ripen bananas quickly?
Place whole, unpeeled bananas on a baking sheet and bake at 300°F (150°C) for 15–20 minutes until the skins darken; allow to cool before mashing. This intensifies sweetness and softens the fruit when you need ripe bananas fast.

Can I prepare these cupcakes ahead of time?
Yes. Bake the cupcakes and start the chocolate cream the day before. Whip the cream, fill the centers with dulce de leche, and pipe the frosting the day you plan to serve them.
