Choco Chip Banana Bars

I'm fond of collecting recipes for me to use it in the future whenever needed...this is a Choco chip Banana Bar recipe, if you don't want choco chips in this banana bar, just ignore the 1C choco chips in the recipe, that would give you a plain banana bar. I've done banana cakes but haven't tried this banana bar. I guess it would just somewhat the same, but just different texture and without the choco chips of course. so here's the recipe:

2 cups all-purpose flour
2 tsps vanilla
2 tsps baking powder
1 egg
3/4 cup margarine
3 pcs ripe bananas, mashed
1 cup sugar
1 cup chocolate chips

Mix flour and baking powder. Set aside.
Cream margarine, sugar and vanilla.
Add egg and bananas and mix well until smooth.
Mix in chocolate chips. Fold in flour mixture until just blended.
Grease a 5x8-inch baking dish and spread the mixture.
Bake in a preheated oven at 350°F for 30 minutes.
Cut into squares when cool.
Serves 6 to 8.
