Japanese Steamed Egg Buns (Mushi Pan)

Makes 8 buns

2 eggs, beaten
3 tablespoons granulated sugar
3 tablespoons sweetened condensed milk
2 tablespoons milk
2 tablespoon vegetable oil
1 teaspoon vanilla extract
2/3 cup all-purpose flour
2 teaspoons baking powder

1. Preheat a steamer filled with water on high heat.

2. Whisk together the beaten eggs, sugar, sweetened condensed milk, milk, vegetable oil, and vanilla extract in a medium-size bowl until smooth.

3. In a separate bowl, whisk together the flour and baking powder. Fold the flour mixture into the egg mixture, just until incorporated.

4. Fill 8 silicone muffin cups (or 8 small ramekins lined with paper muffin liners) with the batter.

5. Place the cups in the steamer and cover.  Steam over high heat for 15 minutes, or until a skewer inserted into one of the buns comes out clean.
