Please help me!
Lucky enough to get a Kitchenaid last week. The first thing I tried making was a coffee sponge cake, recipe from BBC Food website. Disaster
the mixture seemed to curdle when I put the beaten eggs in, even though I added flour with each time I added them, which I also did slowly. It appeared a bit better when I had added the rest of the flour, so I baked it. It turned out a bit dense and flat. I used the beater tool for this one.
Today, I have followed a Kitchenaid recipe, from the official site, which said to use the whisk attachment. It looked like the eggs curdled again, despite them being room temperature and were added with all of the flour, as instructed. Again, it seemed a bit better, so I baked it. This one has also come out flat and dense and is not like when I have made cakes in the past just using an electric hand mixer. It does not seem to have risen much or to be a big cake, despite using 4 eggs and 225g of flour, sugar and butter.
Where am I going wrong? Does anyone also have an idiot proof recipe they can point me in the right direction of please?
I just want to make a nice cake 
TIA
