How to Make Dulce De Leche:
To make your own dulce de leche, remove the wrapper from a can of sweetened condensed milk.
Place the can upside down in a large pot and submerge with water until about 2 inches above the lid.
Watch the water level to make sure it doesn’t drop past the lid. The can must be fully submerged throughout the entire process.
Bring it to a boil, then turn down to a very low heat.
Simmer for 1 hour.
Flip the can in the water and simmer for another hour.
In a stand mixer fitted with a paddle attachment, beat butter on low speed until fluffy.
Sift the confectioners sugar.
Add a few cups of sugar and beat. Add the remaining.
Reserve about 1-2 cup of the white buttercream for the piped rope.
Add the dulce de leche and mix until you get the right consistency. If it’s softer than you want it to be, add more confectioners sugar. Add salt.
