Prepare the pan: Preheat the oven to 170°C (340°F). Grease an 8-inch (20cm) round cake pan and line the bottom with parchment paper if desired.
Make the batter: In a large bowl, whisk the eggs and melted butter until smooth. Add the sweetened condensed milk and whisk until fully combined. Sift in the self-rising flour and gently whisk just until a smooth batter forms. Do not overmix.
Bake: Pour the batter into the prepared pan and smooth the top. Bake for 35–40 minutes, or until the cake is golden and a toothpick inserted into the center comes out clean.
Cool: Let the cake cool completely in the pan. Once cooled, carefully remove from the pan and transfer to a serving plate.
Serve: Dust with powdered sugar if desired. Slice and serve.

Notes
Do not overmix once the flour is added, as this can make the cake denser.
Baking time: Baking times may vary slightly depending on your oven. Start checking for doneness after 35 minutes.
No self-rising flour? Use 160g all-purpose flour and 2 teaspoons baking powder.
Customize the flavor: This cake is incredibly versatile and easy to adapt. Add vanilla extract, lemon zest, or orange zest for extra flavor. You can also mix in chocolate chips, chopped nuts, raisins, dried cranberries, shredded coconut, or even a pinch of cinnamon or cardamom. Just avoid adding too many mix-ins, as they can weigh down the batter and make the cake denser.
Storage: Store covered at room temperature for up to 2 days or refrigerate for up to 5 days.
