# Ingredients:

→ Baba dough

01 - 100g whole milk, lukewarm
02 - 20g granulated sugar
03 - 10g fresh yeast (can substitute with equivalent dry yeast)
04 - 1 egg yolk, room temperature
05 - 1 whole egg, room temperature
06 - 210g bread flour (high protein content)
07 - ¼ teaspoon salt
08 - 60g unsalted butter, room temperature and soft

→ Syrup

09 - 250g water
10 - 150g granulated sugar
11 - 10g fresh lime juice (optional)
12 - Zest of 1 lime (optional)
13 - 70g rum

→ Whipped mascarpone frosting

14 - 200g mascarpone (41% fat), cold
15 - 200g heavy cream (36% fat), cold
16 - 40g powdered sugar, sifted
17 - 2 teaspoons vanilla bean paste

# Instructions:

01 - 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.
04 - 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.
05 - 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.
07 - 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.
09 - 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.
10 - 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.
11 - Whip heavy cream, mascarpone, vanilla bean paste, and powdered sugar for a few minutes until fluffy. Transfer to a piping bag.
12 - Once babas are completely chilled and have absorbed the syrup, pipe the mascarpone frosting on top. Store in an airtight container in the refrigerator.

# Notes:

01 - For best results, ensure all ingredients are at the specified temperatures before beginning.
02 - The rum can be adjusted according to taste preference.
