Step 1

Add a tablespoon of sugar to a microwave-safe glass cup and just enough water to dissolve.

Step 2

Microwave the dissolved sugar for 2 minutes.

Step 3

In a bowl, crack the eggs then add milk, sugar, and vanilla.

Step 4

Whisk until fully combined.

Step 5

Once the sugar has caramelized, carefully swirl it around the bottom of the glass and let it cool slightly.

Step 6

Spoon half of the egg custard mixture into the glass cup.

Step 7

Microwave for about 5 minutes, keeping an eye on the flan to avoid overflow.

Step 8

Once a knife comes out of the flan clean, transfer to an ice bath for a few minutes, then allow the flan to set in the freezer. (Depending on your glass, you may need to wait a few minutes before chilling the hot glass right out of the microwave.)

Step 9

Place a plate or another flat object over top of the glass and quickly turn it oven, then let the flan shake loose and enjoy.
