International Breakfast recipe from the Wikibooks Cookbook.
1 ¾ cup (250 g / 8.8 oz) all-purpose flour ½ cup (110 g / 3.9 oz) granulated sugar 1 tablespoon baking powder ½ cup (40 g / 1.4 oz) semisweet chocolate chips 1 egg ¼ cup (60 ml / 2 fl oz) cooking oil ¼ cup (60 ml / 2 oz) milk 1 cup (250 g / 8.8 oz / 3 ea.) mashed ripe bananas
Measure flour, sugar, baking powder, salt, and chocolate chips into a mixing bowl. Make a well in the center. Beat egg in a small mixing bowl until frothy. Mix in cooking oil, milk, and banana. Pour into well in flour mixture. Stir just to moisten—the batter will be lumpy. Fill greased muffin cups ¾ full. Bake at 400 °F (205 °C) for 15 to 20 minutes.
