Filter Kaapi Cake


If there is one thing you shouldn’t miss when you visit a ‘tambram’ household, it is our piping hot filter kaapi. There is something special about sipping filter coffee while listening to the suprabhatam in M.S. Subbulakshmi’s voice every morning.

I always loved it when my mum woke me up with a steaming hot tumbler of frothy filter coffee. The aroma of freshly brewed decoction is something I always look forward to when I visit my parents home.

This morning while sipping my cuppa, I realized I haven’t made a coffee cake for way too long! So, my fresh strong filter coffee decoction found its way into this super delicious cake.

Did I mention that this cake is egg free and 100% whole wheat? Aah now I got you even more interested. Go ahead turn those percolators on, get brewing and baking.


Prep Time           10 minutes

Cook Time           40 minutes


1 and 1/3 cups whole wheat flour

1 and 1/2 tsps baking powder

1 cup milk

3 tbsps butter [salted]

2 tsps cornflour

1/4 tsp baking soda

1/4 cup Filter Coffee Decoction

1 cup Powdered sugar/ Cane sugar

1/4 cup Chopped Walnuts [optional]

1 tsp vanilla extract

1 tsp water


  1. Pre heat oven at 180 C for 10 minutes.
  2. Sift the whole wheat flour and baking powder. Set aside.
  3. Heat the milk until it just comes to a boil.
  4. Add the coffee decoction, vanilla extract, butter and powdered sugar to the hot milk. Pulse once or twice in an electric mixer to blend the ingredients really well.
  5. Mix the cornflour and baking soda together.
  6. Add water to the above and mix well until no lumps remain.
  7. Add the cornflour paste to the wet ingredient mixture and whisk.
  8. Set aside for a couple of minutes.
  9. Pour the warm mixture into the sifted flour and fold in the batter until no lumps remain.
  10. You may add chopped walnuts at this stage. Simply fold the chopped nuts into the batter [avoid over-mixing].
  11. Pour into a greased 7 inch pan.
  12. Bake in the pre heated oven at 180 C for 35-40 minutes or until a skewer inserted comes out clean.
  13. After 5 minutes, invert over a wire rack and allow to cool.
  14. Slice once completely cooled.


  • For preparing coffee decoction- Take 2 heaped tablespoons of filter coffee powder in the percolator/ coffee filter. Add 1/2 a cup of boiling hot water. Allow the decoction to drip down and take its time. This is the best way to get the maximum flavour.
  • In case you use unsalted butter, add 1/4 tsp of salt to the flour while sifting.
  • Using cane sugar in place of regular white refined sugar is a great idea. It enhances both the colour and flavour of the cake.
  • If the walnuts you use aren't crunchy, toast them for a couple of minutes in your oven before adding it into the cake batter.
  • Use good quality filter coffee powder for getting that heavenly aroma and coffee 'kick'.


Happy Baking.
