Lemon cake (Starbucks secret recipe)

I am not a big fan of Starbucks I must confess. I find their coffee pretty weak and horrid and I can’t remember much from eating their pastries. However, when I saw this recipe going around in Facebook, the picture looked very delicious and lemon cakes are my soft spots. So I tried it and it is every bit as delicious as it looked. Here is the recipe, adapted to Thermomix and the European measurements (I include the cup measures also for those who use it).

240g (1 1/2 cup) plain flour, sieved
1/2 tsp baking soda

  1. This looks lovely, Nora, thanks for converting it to Thermomix!

  2. I think you’ll find “someone on facebook” is pulling your leg. Starbucks cakes are made on an industrial scale with industrial ingredients to match. Perhaps if you threw in an assortment of enhancers, e-numbers, stabilizers, gums, fats, improvers and other gunk, then you might have something more akin to the original. This one is just another retro-engineered taste-alike from some random internet geek.

    • Hi Pete, you’re dead right in saying the cakes in those coffee chains are probably industrially made. I wasn’t really interested in making a Starbucks cake, it was the photo of the cake on Facebook that appealed to me, and I was happy it turned out very nice 🙂

  3. I agree with you on the coffee!
    What sort of oil did you use for the cake?-looks delicious.

  4. bonsoir nora,très heureuse de te retrouvĂ© avec ce superbe cake,qui a l’air
    bien délicieux.bonne soirée bises

  5. Saw this on Facebook as well but the cup measurements where print me off so Thanks for converting!
    One question. Can you get lemon essence in Ireland? Never seen it. Or could you just leave it out?

    • Hi Britta, you can find lemon essence/extract in most supermarkets in Ireland. Mine is from the brand Dr Oetker…

  6. I’m not a fan of Starbucks’ pasteries either… However, your cake seems so yummy!! Should I try the Lemon cake the next time I walk by a Starbucks?
