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, early in the morning while listening to the suprabhatam in M.S. Subbulakshmi’s voice.

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.

Recipe Notes

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.

    Hey! Thanks for such a great recipe.. Tried it as soon as i saw ur post but didn’t get the perfect net after cutting the cake as seen in ur pic.. Looks like cake would rise more.. Baked for 40 min at 180. Can u please help me find out wer did i go wrong.

  2. Surabhi says:

    Looks awesome . Is cane sugar same as jaggery ?

  3. Akila Subramanian says:

    Hi Shruti. Thanks for trying the recipe. Is your cake dense? There can be several reasons for that – like over mixing, old baking powder/soda, if the flour isn’t sifted well, if you checked on your cake too early/ opened the oven door. And since oven temperature and time often vary perhaps your cake needed a bit more time ?

  4. Akila Subramanian says:

    Surabhi Thank you. Cane sugar is a variety of brown sugar. Not the same as jaggery

  5. Shruti Agrawal says:

    Hi Akila, thanks for ur prompt response.. I think the cake was done in 40 min.. But over mixing could b the reason.. Also the consistency of my batter was very thin.. Was that how it was supposed to b? Coz i didn’t have coffee filter, i used a normal coffee decoction by mixing coffee n boiling water & letting it set for sometime

  6. Hello, can I use Bru coffee for this recipe?the instant variety?

  7. Akila Subramanian says:

    Hi Shruti. I wouldn’t call the batter runny. Pouring consistency yes. Perhaps you added a little more liquid than required.

  8. Akila Subramanian says:

    Hi Aarchrjn. Yes you can but ideally use a ‘filter coffee powder’ for this recipe .[ Bru also has roast and ground filter coffee powder that works quite well]

  9. Rekha says:

    Hi Akila, can we use jaggery in this recipe? If so, pls mention the amount also. Thanks in advance

  10. Shilpa Jain says:

    If using the instant coffee what shd be the quantity?

  11. Jeevan says:

    1. Akila Subramanian says:
