Preheat your oven to 325°F (160°C).

Grease and line a 9-inch loaf pan or round cake tin with parchment paper.

In a large mixing bowl, whisk the eggs until light and frothy.

Add the sweetened condensed milk and melted butter, whisking until completely smooth.

Gently fold in the sifted self-rising flour until just combined. Do not overmix.

Pour the batter into the prepared pan and smooth the top.

Bake for 35-45 minutes, or until a skewer inserted into the center comes out clean.

Let the cake cool in the pan for 10 minutes before transferring to a wire rack to cool completely.

Dust with powdered sugar before serving.
