Please can you help me with your professional advice.
My cup cakes always crack on the top and don't seem to bake evenly 
I use the betty crocker mix and bake it at 160Deg Cel. I fill the cup cake liners 3/4 of the way but they always end up with peaks and cracks.
What am i doing wrong. This happens with all my recipes. My oven is aerotherm.
Your advice would be appreciated
Thanks in advance
Try a few different things...
I preheat my oven to 350F and then drop it to 325 when I put the cupcakes in.
Also - if using a box mix, replace the water (regardless of the amount) with 1 cup of buttermilk, then add an extra egg. It changes the density of the cupcakes and I find they form better.
For amount - I use a regular ice cream scoop and find it's the perfect amount
Good luck!
I get that problem when the oven is too hot and the cupcakes are too close to the top of the oven,
Like the above post says, try decreasing the temp and maybe putting them lower down in the oven.
Hope this helps
