Preheat your oven to 180°C (350°F) while you prepare the cake batter.
Gently melt the unsalted butter in a small saucepan or microwave and set it aside to cool slightly.
In a blender, combine the eggs, vanilla extract, melted butter, condensed milk, lime juice, corn kernels, baking powder, pinch of salt, and flour. Add in the flour last, ensuring no clumps form. Blend until the mixture is well combined and smooth.
Grease and lightly flour a 9IN diameter cake pan to prevent sticking. Add in the corn mix.
Place in the preheated oven and bake for 40 minutes, or until the top is golden brown.
Once the cake is baked, allow it to cool in the pan for 10 minutes before taking it off the mold. This will help the cake to set and easier to remove from the pan.
Serve and sprinkle with some icing sugar and eat with some berries (optional).
