Crispy on the outside, soft on the inside, and stuffed with creamy peanut butter, Hong Kong French toast is one of the most popular treats served in Hong Kong cafés.
Spread peanut butter evenly on two slices of bread and sandwich them together. Trim off the crusts with a sharp knife.
In a shallow bowl, whisk together the egg, milk, palm sugar, and salt until well combined). Dip the bread sandwich into the egg mixture, coating all sides evenly.
Heat a lightly greased non-stick pan over medium heat. Transfer the coated bread to the pan and cook until golden brown on all sides.
Transfer the toast to a serving plate. Drizzle with condensed milk, golden syrup, or both, and top with a thick slice of butter before serving.
Notes
Use slightly stale bread - Bread that is 1 to 2 days old absorbs the egg mixture better and holds its shape during cooking. Fresh bread tends to become too soft and may fall apart.
Don't skip trimming the crusts - Removing the crusts helps the bread absorb the egg mixture more evenly and gives the toast its classic Hong Kong café appearance.
Lightly grease the pan - A quick spray of cooking oil or a thin layer of butter helps prevent sticking and promotes even browning without making the toast greasy.
Cook over medium heat - Avoid high heat, which can brown the outside too quickly before the center is heated through. Medium heat allows the toast to develop a golden crust while staying soft and fluffy inside.
Serve immediately - Hong Kong French toast is best enjoyed fresh off the pan while the butter is still melting and the condensed milk or golden syrup is warm and glossy.
Try the air fryer - While I haven't personally tested this recipe in an air fryer, many readers have success making French toast in one. If you try it, lightly spray the bread with oil and cook until golden brown, flipping halfway through cooking.
