Mix sugar with lukewarm milk then sprinkle yeast on top. Allow to rest in a warm kitchen for 10 minutes until the yeast begins to foam.
02 -
Place the activated yeast mixture into a stand mixer fitted with the kneading hook. Mix together with the egg and egg yolk until well combined.
03 -
Mix in flour and salt, then knead until the dough begins to come together.

Gradually add soft butter in small chunks. Continue kneading for 10 minutes on medium-high speed until the dough becomes elastic, shiny, and no longer sticky.

Transfer the dough to a bowl, cover with plastic wrap or a tea towel, and let it rise at room temperature for 1-2 hours.
06 -
After the dough has risen, gently deflate it and knead for a minute. Divide into 8 equal portions and shape into balls. Place them into molds, using a small amount of flour if needed.

Allow the shaped babas to proof at room temperature for another 1-2 hours until visibly risen.
08 -
Preheat oven to 190°C. Once babas are properly risen, place them in the oven, reduce temperature to 180°C and bake for about 20 minutes until golden brown.

While the babas are finishing baking, combine water, sugar, lime zest, and lime juice in a saucepan. Boil for about 5 minutes until slightly thickened, then stir in rum.

Pour half of the hot syrup over the babas immediately after removing them from the oven. Then unmold them onto a plate or baking pan and pour the remaining syrup over. Turn the babas in the syrup several times and allow to cool completely.

Whip heavy cream, mascarpone, vanilla bean paste, and powdered sugar for a few minutes until fluffy. Transfer to a piping bag.

Once babas are completely chilled and have absorbed the syrup, pipe the mascarpone frosting on top. Store in an airtight container in the refrigerator.
