1/4 cup butter, divided
1/4 cup packed brown sugar
1 teaspoon vanilla extract
1 1/2 cups all-purpose flour
1 1/2 teaspoons baking soda
1/3 teaspoon salt
1 cup cornflakes cereal
1 (10 ounce) can evaporated milk
Preheat oven to 350 degrees F (175 degrees C). Grease muffin cups or line with paper liners.
In a large bowl, cream together 1/2 cup butter, brown sugar and 1 teaspoon vanilla until smooth. Beat in flour, baking soda and salt. Mix in cornflakes cereal and milk until well blended.
Spoon the batter into the prepared muffin liners. Sprinkle the cornflakes over the batter so that they are completely covered.
Bake in preheated oven for 25 to 30 minutes, until a toothpick inserted in center of muffin comes out clean. Serve warm.
