Chocolate detox drink: The Shrink Mummy Shake

Who’s ready for chocolate detox? On days when you are determined to be a good girl, indulge in my favourite Shrink Mummy Shake. I can guarantee that it will fill you up until lunchtime and it’s even got cocoa in it. Ka-pow!



It may be New Year’s Day but this is not, repeat NOT a diet post.

A couple of years ago, I joined a group who were going to blog about weight loss. I didn’t *cough* last long (neither did anyone) and the spin off diet blog, known as ‘Shrink Mummy’ lasted only about 10 posts.

I don’t mind reading about weight loss. I love to read stuff to get motivated. But frankly there is nothing more tedious and navel gazing than reading someone else’s journal about THEIR diet.

(If anyone has started blogging about diets this week may I reassure you that this post was written on December 5th 2012 and in no way meant to be a dig at anyone.)

I just find blogging about dieting and reading anyone else’s blow by blow account of what they consumed that day and minute changes on the scales or tape measure crashingly dull.

Come back and tell me about it when you’ve lost two stone and kept it off for six months or more. Then I’m all ears.

In the meantime, let me share with you the one good thing that came out of Shrink Mummy which was the Shrink Mummy Shake.

It’s inspired by the hideous green goop that Rene Russo drank, bespectacled in dark glasses and hungover in one of my favourite ever films, the 90s remake of The Thomas Crown Affair.

Rene seems to suffer over her revolting dark green drink but may I reassure you that THIS version is the healthiest chocolate milkshake I ever had. If I have one of these for breakfast it sets me up for the day and keeps me on track with whatever fleeting good intentions I’ve developed since most recent over indulgence.

You can tweak the supplements between barleygrass and spirulina (sold in foil pouches at Holland and Barrett etc), change the thickening ingredient between oatmeal, wheatgerm, ground flax etc and whichever type of milk – rice, oat, almond, soy or plain old dairy is completely up to you.

Below I present my favourite version. Cocoa powder is not essential but just one level tablespoon turns this chocolate detox drink into a treat rather than a guilt trip.  Enjoy.

    Somehow a shake, smoothie or any other kind of drink never seems to fill me up, I know it works for some people but not for me. I’m a firm believer in portion control, so will be back on my 50:50 diet i.e. eat half what you usually eat, no special recipes and it seems to work for me. Need to get back to it now the festive season is over!

      I’ve never done any slimfast shakes or anything but this genuinely fills you up. The oat meal has same effect as porridge!

  2. Shauna says

    What could you substitute barley grass powder with (all bran maybe?) and also could you use honey instead of the algarve nectar?

  3. says

    Love the look of this, it looks like chocolate porridge, rich and delicious and I’m really pleased you’ve entered it into We Should Cocoa – thank you.

    • Sarah, Maison Cupcake says

      Yes you can do that. Try the Linwoods ranges in Holland and Barratt for alternative supplements if you like.

    will definitely try this I have all the ingredients I love green barley grass, spirulina, wheatgrass etc. I would probably add chia and flax seeds and swap the oat milk for coconut milk which I discovered last year, very tasty!

    I’ll have to give this a go – we go through a LOT of oatmilk in our house, with a dairy intolerant toddler, but I’ve not used it for grown-up smoothies – I shall have to remedy that… this looks lovely!

    • Sarah, Maison Cupcake says

      I don’t but I did work out it was 10 Weight Watchers’ pro points. It’s very filling and you won’t be tempted to snack between meals.

    So I used spirulina instead of the barley grass…is it suppose to taste good or gross? Mine was horrible! Any suggestions?

    • Sarah, Maison Cupcake says

      Spirulina is an acquired taste. It’s more bitter than barley grass. Maybe use less of it?
