自从新年过后，体重一直“高高在上”，没有下降的意思。有时想吃蛋糕，还要＂三思＂。做女人真辛苦…… 可是当我看到这无油的香蕉蛋糕，就一定要吃吃吃……食谱取自Happy home baking，是茨木くみ子＂好吃不发胖低卡甜点＂
100g cake flour
30g cocoa powder （我用奶粉）
1/2 teaspoon baking powder
2 large eggs, room temperature
70g caster sugar
150g banana, mashed
1 teaspoon vanilla extract（没放）
1 tablespoon rum（没放）
1.Sieve together cake flour, cocoa powder and baking powder. Sieve the flour mixture twice and set it aside.
2.Place eggs and caster sugar in a large mixing bowl. With an electric mixer, whisk the mixture at medium-high speed till it becomes thick, pale and triple in volume. This should take about 5 to 6 mins. The batter should leave a ribbon like trail when the whisk/paddle is lifted. Turn to low speed, and beat for another 1~2 mins. This is to stablise the air bubbles in the batter.
3.Add in the mashed banana and Fold in with a spatula.
4.Add in the milk, vanilla extract and rum (do not pour in one spot, instead, gently drizzle over to prevent from deflating the batter). Fold in with a spatula, do not stir.
5.Sieve over the flour mixture in 3 separate additions. Each time Fold in the flour carefully with a spatula, making sure there is no pockets of flour being trapped at the bottom of the bowl. Do not stir the batter with the spatula, it will cause the batter to deflate.
6.Bake in preheated oven at 180 degC for 15mins or until a toothpick inserted into the centre comes out almost clean.
