Dulce De Leche Cupcakes
These dulce de leche cupcakes feature a tender brown sugar sponge, a hidden pocket of gooey caramel, and a silky whipped caramel buttercream.
- Brown sugar provides molasses notes that mimic the caramelized flavor of the filling without overloading the cake with simple sugars.
- Sour cream adds acidity to tenderize the gluten and balance the sweetness of the rich filling.
- Whipping the buttercream with a paddle attachment for a full five minutes forces out large air pockets, creating a silky, professional finish.
I still remember the afternoon I tried to make my own milk caramel by boiling a closed can of sweetened condensed milk for three hours, only for it to explode and paint my kitchen ceiling a sticky, metallic brown.
My husband still points out a tiny, caramelized spot on the light fixture whenever I bring out the cupcake pans.
The real tragedy of most caramel cupcakes isn't the ceiling paint; it's that they are relentlessly, tooth-achingly sweet without any actual depth of flavor, a problem that became painfully obvious during my third testing round when the cakes turned out like lead weights.
When you just dump caramel into a standard vanilla batter, the excess sugar completely disrupts the delicate protein matrix of the cake, leaving you with a dense, sunken crumb that clings to the roof of your mouth.
Trust me on this one.
To fix this, we are using a deeply toasted brown sugar base and coring out the center to squeeze in pure, unadulterated canned milk caramel.
You do not need to stand over a copper pot with a candy thermometer worrying about third-degree burns, because a good store-bought can of canned caramel does the heavy lifting beautifully.
Dulce De Leche Cupcakes
Ingredients
- 1.5 cups (180g) all-purpose flour
- 1.5 tsp baking powder
- 0.5 tsp Diamond Crystal kosher salt (or 0.25 tsp fine table salt)
- 0.5 cup (113g) unsalted butter, softened to room temperature
- 0.75 cup (150g) packed light brown sugar
- 2 large eggs, room temperature
- 1 tsp pure vanilla extract
- 0.5 cup (120g) sour cream, room temperature
- 0.25 cup (60ml) whole milk
- 1 can (13.4 oz / 380g) Nestlé La Lechera Dulce de Leche (divided)
- 1 cup (226g) unsalted butter, softened (for frosting)
- 2 cups (240g) powdered sugar
Directions
- Preheat your oven to 350°F (175°C) and line a 12-cup muffin tin with paper liners.
- In a medium bowl, whisk together the flour, baking powder, and Diamond Crystal kosher salt.
- In a stand mixer fitted with the paddle attachment, beat the softened butter and light brown sugar on medium-high speed for 3 minutes until light and fluffy.
- Add the eggs one at a time, beating well after each addition, then stir in the vanilla extract.
- Reduce the mixer speed to low; add the flour mixture in three additions, alternating with the sour cream and milk, mixing just until combined.
- Divide the batter evenly among the cupcake liners and bake for 18 to 20 minutes, or until a toothpick inserted into the center comes out clean.
- Let the cupcakes cool in the pan for 5 minutes, then transfer them to a wire rack to cool completely.
- Use a cupcake corer or a small knife to cut a pocket out of the center of each cooled cupcake, then spoon or pipe about 1 tablespoon of dulce de leche into each hole.
- For the frosting, beat the remaining 1 cup of butter and 0.5 cup of dulce de leche in a clean mixer bowl for 2 minutes, then gradually add the powdered sugar until smooth and fluffy.
- Pipe the frosting onto the cupcakes and drizzle with any remaining dulce de leche before serving.
Notes
- I highly recommend Nestlé La Lechera Dulce de Leche (1 can is 13.4 oz or 380g). If using homemade, ensure it has cooled to room temperature to prevent melting the cake structure.
- Sour cream is vital here because its lactic acid breaks down the flour's gluten bonds, ensuring a tender crumb that doesn't turn rubbery under the weight of the caramel filling.
- Do not attempt to warm the dulce de leche in the microwave while it is still in the metal can; transfer it to a glass bowl first to avoid a kitchen fire.
- After a day in the fridge, the starch gelatinization in the cake tightens up, making the sponge slightly denser, so always bring them to room temperature for 30 minutes before eating.
Serving Suggestions
These cupcakes are incredibly rich on their own, but you can easily turn them into a show-stopping dessert spread with a few simple additions.
- Serve alongside a hot cup of coffee splashed with our Homemade Coffee Creamer to cut through the sweet caramel notes.
- If you love stuffed treats, try pairing these on a dessert platter with our Banana Pudding Cupcakes with Whipped Cream Frosting.
- For a fruit-forward contrast, add a light drizzle of homemade Strawberry Sauce over the top of the buttercream.
- If you want to offer a variety of caramel textures, serve these alongside our No Bake Salted Caramel Cheesecake Cups.
Storage and Reheating
Store these cupcakes in an airtight container in the refrigerator for up to four days to keep the dairy-rich buttercream from spoiling.
The cold environment will make the butter in the frosting firm up like a block of chocolate.
Do not panic.
Simply set them on the counter for thirty minutes before serving, allowing the ambient heat to soften the sponge and restore the frosting to its silky glory.
You can also freeze the unfrosted, cored cupcakes for up to three months wrapped tightly in plastic wrap.
Ingredient Substitutes
If you find yourself missing a few key items in your pantry, these simple swaps will keep your baking session on track without sacrificing texture.
- Light Brown Sugar: Dark brown sugar can be used for a deeper molasses flavor, though it will make the sponge slightly wetter.
- Sour Cream: Full-fat Greek yogurt works as a direct 1:1 swap without losing the necessary acidity.
- All-Purpose Flour: A 1:1 gluten-free baking flour blend works beautifully, though you may need to let the batter rest for 10 minutes before baking to prevent grittiness.
Let me know if you manage to keep yourself from eating the dulce de leche straight from the can with a spoon before it actually makes it into the cupcakes—I certainly couldn't.
