Preheat oven to 350°F. Grease 8 ramekins or muffin cups.
Whisk flour, baking powder, and salt. Set aside.
Beat eggs and sugar on high until pale and tripled, about 5 minutes.
Fold in flour mix gently, then stir in 1/3 cup whole milk and vanilla.
Divide batter among ramekins and bake 15–18 minutes until a toothpick comes out clean.
Cool 10 minutes, then poke tops with a skewer.
Mix evaporated milk, condensed milk, and 1/2 cup heavy cream. Pour over cakes slowly.
Chill at least 2 hours or overnight.
Whip 1 cup heavy cream with powdered sugar to soft peaks. Top each cup and dust with cinnamon.
