SUMMARISE AND SAVE THIS RECIPE
What is Dulce de Leche?
Dulce de leche is a rich, caramel-like sauce made by slowly heating sweetened milk until it thickens and takes on a golden brown color. The name translates from Spanish as "sweet milk." Many people in Latin American countries love to use dulce de leche in various desserts, including cakes, pastries, and cookies. The slow cooking process caramelizes the sugars in the milk, giving it a distinctive caramel flavor and creamy texture. Dulce de leche can be made at home or purchased pre-made from stores.
Homemade vs. Store-Bought Dulce de Leche
When it comes to dulce de leche, you can either make it at home or buy it pre-made. Homemade dulce de leche develops a deeper, richer flavor when you cook it longer and adjust it with additions like vanilla or a pinch of salt. The process involves simmering sweetened condensed milk until it becomes thick and caramel-like, giving it a creamy texture and a delicious, complex taste .
Store-bought dulce de leche is convenient and consistent. It's perfect for when you need a quick, ready-to-use option. While it may not have the same depth of flavor as homemade, it's still sweet and smooth, making it great for spreading on desserts or using as a filling) .
Ultimately, the choice between homemade and store-bought depends on whether you prioritize convenience or want a potentially richer flavor. You can use both in a variety of delicious treats because they are versatile.

Ingredients in Dulce de Leche Buttercream
The ingredients for the Dulce de Leche Buttercream are simple and consist of only two components:
- Unsalted Butter (250g / 9 oz): This is the base of the buttercream, providing a rich, creamy texture. Unsalted butter is used to control the salt content, allowing the dulce de leche's sweetness to shine through.
- Dulce de Leche (250g / 9 oz): This sweet, caramel-like sauce adds a deep, rich flavor to the buttercream. It acts as the sweetener and provides a luscious caramel taste, eliminating the need for powdered sugar.
Use equal weights for both ingredients, making it easy to scale the recipe up or down based on your needs.
How To Make Dulce de Leche Buttercream
Beat the Butter: Start by adding 250g (9 oz) of unsalted butter to a mixing bowl. Use an electric mixer to beat the butter for about 5 minutes until it becomes light and fluffy. This step helps to create a smooth and airy base for the buttercream.

Add Dulce de Leche: Next, incorporate 250g (9 oz) of dulce de leche into the butter. Mix on medium speed until the mixture is fully combined and smooth. The dulce de leche provides a rich caramel flavor and acts as the sweetener in the buttercream.

Remove Air Bubbles: After mixing, use a silicone spatula to gently massage and mix the buttercream for a minute or two. This helps to knock out any large air bubbles that may have formed during the mixing process, ensuring a smooth and consistent texture.

Use and Storage: The buttercream is now ready to use for decorating cupcakes, cakes, or as a filling for various desserts such as donuts, macarons and whoopie pies. If not using immediately, you can store it in the refrigerator for up to one week or freeze it for up to two months.

Fay's Top Tip
