I just deep-fried and filled a batch of the thing above. They turned out delicious, so I’m sharing here.

Here’s a link for the recipe for the dough; I followed it closely, the only thing was that I subbed the butter with veg oil. The recipe yielded ~20 of them, but this depends a lot on the size that you cut them.

Recipe for the custard filling:

• 300g sweetened condensed milk
• 300g 20% fat milk cream
• 300g whole milk
• 2 eggs
• vanilla essence
• [optional] 1/2 tsp cornstarch

Just mix everything together until homogeneous, then heat it on low fire, while stirring constantly, until it thickens. I didn’t use the cornstarch because I wanted it slightly runnier, but do add it if you like a thicker custard.
