Step 1

Preheat oven to 175 Celcius (350 Fahrenheit). Grease and flour an 8.5"x4.5" loaf pan, set aside.

Step 2

Sift together cake flour, baking powder, and salt in a mixing bowl. Set aside.

Step 3

In another mixing bowl, cream together butter and sugar with medium speed until white and fluffy. Add in sweetened condensed milk and vanilla, beat until well mixed. Add eggs, one at a time, and beat until well mixed. Sift in the flour mixture and beat with the lowest speed (or use a spatula) just until you no longer see flour streaks.

Step 4

Pour the batter into prepared pan, bake for 35-40 minutes, or until a cake tester comes out clean.

Step 5

Cool the cake in the pan for 10 minutes, then carefully remove from pan and cool on a wire rack to room temperature. Cut into slices and serve.
