Step‑by‑Step Instructions for Dulce de Leche Cupcakes
Step 1: Preheat the Oven
Start by preheating your oven to 350°F (175°C). While the oven heats up, take a muffin tin and line it with cupcake wrappers. The freshly prepared liners are ready to hold your delicious dulce de leche cupcakes as they rise and bake to perfection.
Step 2: Mix the Dry Ingredients
In a medium bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt until well combined. This step is essential for ensuring your cupcakes have a uniform texture and rise beautifully. Once mixed, set the bowl aside, allowing the dry ingredients to meld together while you prepare the next step.
Step 3: Prepare the Batter
In a large mixing bowl, cream the unsalted butter and light brown sugar together using a hand mixer or stand mixer until the mixture is light and fluffy, which should take about 3-4 minutes. Add the large eggs one at a time, mixing well after each addition. Finally, stir in the pure vanilla extract, full-fat sour cream, and vegetable oil, creating a rich and creamy batter.
Step 4: Combine Mixtures
Gradually add the previously mixed dry ingredients to the wet mixture, alternating with the whole milk to keep the batter smooth. Mix until just combined—be careful not to overmix, as you want your dulce de leche cupcakes to be light and fluffy rather than dense. Scrape down the sides of the bowl to incorporate all ingredients.
Step 5: Bake Cupcakes
Fill each cupcake liner about three-quarters full with the batter, ensuring they have room to rise. Place the muffin tin in the preheated oven and bake for 15-18 minutes, or until a toothpick inserted in the center comes out clean. Once baked, allow the cupcakes to cool completely on a wire rack to avoid sogginess.
Step 6: Make Frosting
In a clean mixing bowl, beat the unsalted butter until creamy and smooth. Gradually add sifted confectioners’ sugar, mixing on low speed until combined. Once the sugar is incorporated, blend in the dulce de leche and a pinch of salt. Adjust the consistency as needed with additional milk or sugar until you achieve a light and fluffy frosting perfect for topping your cupcakes.
Step 7: Core and Fill
Using a cupcake corer or a small knife, carefully create a hole in the center of each cooled cupcake to form a pocket for the dulce de leche filling. Fill each cavity with a generous spoonful of your dulce de leche, allowing the sweet and creamy goodness to absorb into the cupcake for an irresistible treat.
Step 8: Frost Cupcakes
Finally, generously frost the tops of each filled cupcake with the luscious buttercream frosting using a spatula or piping bag. For an extra touch of sweetness, consider drizzling additional dulce de leche over the frosted cupcakes, creating a stunning presentation. Your delightful dulce de leche cupcakes are now ready to impress!

You can bake the cupcakes up to 3 days in advance and store them unfrosted in an airtight container at room temperature for optimal freshness. To maintain their fluffy texture, allow them to cool completely before storing. Additionally, the dulce de leche filling can be prepared 24 hours ahead; simply refrigerate it until you’re ready to fill the cupcakes. When you’re ready to serve, core and fill the cupcakes with the dulce de leche, frost them with your prepared buttercream, and they’ll be just as delicious and delightful, saving you time on busy days!
How to Store and Freeze Dulce de Leche Cupcakes
Room Temperature: Store unfrosted dulce de leche cupcakes in an airtight container for up to 3 days. This keeps them moist while maintaining their delightful texture.
Fridge: If you need to keep them longer, place the unfrosted cupcakes in the refrigerator for up to 5 days. Ensure they are in an airtight container to prevent drying out.
Freezer: For longer storage, freeze unfrosted cupcakes for up to 3 months. Wrap each cupcake tightly in plastic wrap, then place them in a freezer-safe bag. Avoid freezing assembled cupcakes due to the filling’s consistency.
Reheating: To enjoy, simply thaw frosted or unfrosted cupcakes at room temperature. If reheating, microwave for about 10-15 seconds to restore their fluffy texture before serving.

Dulce de Leche Cupcakes Recipe FAQs
What’s the best way to choose ripe ingredients for the cupcakes?
Absolutely! For the best flavor and texture, use ripe ingredients. When selecting eggs, ensure they are fresh and stored properly. Look for firm eggs without cracks. For butter, choose unsalted versions to control the salt level in your recipe. Using room-temperature butter and eggs will help them blend evenly, resulting in a fluffier cupcake.
How should I store leftover cupcakes?
Very good question! Store unfrosted dulce de leche cupcakes in an airtight container at room temperature for up to 3 days to keep them moist. If you need to keep them longer, move them to the fridge for up to 5 days—just make sure they’re sealed tightly to prevent drying out.
Can I freeze these dulce de leche cupcakes?
Definitely! To freeze, wrap each unfrosted cupcake tightly in plastic wrap, then place them in a freezer-safe bag or container. They can be frozen for up to 3 months. Just remember—not to freeze assembled cupcakes, as the filling can alter the texture when thawed.
What should I do if my cupcakes don’t rise well?
If your cupcakes aren’t rising, it might be due to old baking powder or baking soda. Check the expiration dates on these leavening agents to ensure they’re fresh. Also, make sure you’re not overmixing the batter; gentle folding is key to keeping your cupcakes light and fluffy.
Are there any dietary considerations for these cupcakes?
Absolutely! These delicious dulce de leche cupcakes contain gluten and dairy, which may not be suitable for everyone. For a gluten-free option, try substituting the all-purpose flour with a gluten-free baking blend. If you have a dairy allergy, you can use dairy-free butter and a plant-based yogurt instead of sour cream to still achieve that creamy texture.
What can I do to adjust the sweetness of the cupcakes?
If you’re looking to reduce sweetness, consider cutting back on the light brown sugar in the cupcake batter or the amount of dulce de leche you use in the frosting. You could also try using a less sweet frosting variation, such as cream cheese frosting, which works beautifully with the dulce de leche flavor and balances out the sweetness nicely.
