Bananas have an incredible silky, smooth texture and amazingly comforting natural aroma. They are rich in potassium and have many other health benefits. And once they marry with chocolate chips in this cake, you just can’t get enough of it! What’s more is that it’s a healthy, wholesome cake considering the wholewheat flour and the oatmeal it contains. And that’s not all there is to it! It’s a quick, fuss-free recipe you can whip up real quick! So what else can you ask for in a cake?
This is another one of those recipes with a little anecdote. As far as I’m concerned, it’s from my Mom’s repertoire. But originally it’s from one of my Mom’s friends, Ayşe Heinbecker, from Ottawa way back in the 90s. My Mom tells me Mrs.Heinbecker’s daughter Yasemin used to make this cake. The paper on which Mrs. Heinbecker wrote this recipe for my Mom nearly 25 years ago now rests neatly among other similar papers in one of my culinary scrapbooks. And every time I bake this cake, its fragrance spreads out memories from the past in every corner of our home…

  • 1 cup (240 gr) sugar (I use soft brown sugar)

  • ½ cup (125 ml) sour milk (1 tbsp vinegar added – I use kephir instead)

  • 1 cup (150 gr) whole wheat flour
  • 1 cup (80gr) quick cooking oats
  • 1 tsp baking soda

  1. Heat oven to 175 C (350 F). Grease and line a  25×35 cm (10×14 inch) rectangular cake pan with baking sheet.
  2. In a large bowl mix oil and sugar with an electric mixer on low speed. Beat in eggs, one at a time. (Actually you don’t have to use an electric mixer for this cake batter. You can just as well mix everything by hand with a whisk.)
  3. Add mashed banana, sour milk and vanilla and mix well. You can also use the same amount of kephir or buttermilk instead of sour milk.
  4. Now add flour, oatmeal, baking soda, baking powder and chocolate chips. Mix with a spoon until all ingredients are well incorporated. (If you don’t have chocolate chips at hand you may also use chopped eating chocolate instead)
  5. Pour into prepared cake pan and bake for 30-35 minutes.
  6. Leave to cool in pan. Then cut into squares and serve.
