This is a Thermomix recipe however you could just make it in your normal food processor and there's basically two steps. First blitz the sugar and peeled lemon rind until it resembles fine breadcrumb consistency and then throw everything else in and mix it up and then it's ready to put in your pan and then top with your raspberries or blueberries.
I made individual muffins rather than the one large cake but you could do either and if you have a fancy Friand pan even better. Also in the recipe link on Corrie's web site she forgets to include the desiccated coconut in the recipe instructions when putting all the other ingredients in so just remember if you are on her recipe link. I baked my muffins for 20-25 minutes as it's quite a thick but runny recipe however just do the skewer test and you'll get a perfect Raspberry Lemon Muffin. The recipe made 18 muffins and I just sprinkled them with icing sugar once completely cooled down. Here's the recipe I made.
1 cup of sugar (Corrie's recipe states raw however I just used white which was on hand)
Rind of 1 lemon (I used a potato peeler to get all the rind off before squeezing the lemon)
Juice of 1 lemon
125 gms of butter
1 cup of milk
1/2 cup of shredded or desiccated coconut (I used desiccated)
One and a half cups of SR flour (or GF flour)
1 cup of frozen raspberries (or blueberries) (I think I only used 1/2 cup in the end)
Heat oven to 170 degrees C fan forced oven (180 normal).
Place sugar and lemon rind in Thermomix and process for 10 seconds on speed 9.
Add in butter, eggs, lemon juice, milk, coconut and flour and mix for 20 seconds on speed 4. Scrape down the bowl once in between.
Pour into individual muffin cases (patty cake wrapper) and sprinkle a few raspberries on top of the mixture. There is no need to push them into the mix just sit them on top.
Bake for 20-25 minutes and use the skewer test to make sure the middle is cooked through. I set two timers on my phone one for 20 minutes and one for 25 minutes so I can check at both times.
When a skewer comes out clean, take them out of the oven and leave them in the tins for 10 minutes to cool down and then lift them out onto a cooling rack. Once completely cool sprinkle with icing sugar and enjoy.....these are awesome and would also freeze well I would think. Give these a go you won't regret it.
