This might sound silly but what is #3 setting? I have a gas oven but it is digital and only has the temp in degrees.
BY cream do you mean sour cream asn this is a WASC cake or do you mean cream
I also am wondering if you mean sour cream as an ingredient which is WASC style, or by "cream" do you mean heavy cream?
it`s sour cream, mexican style could work well you need a Thick cream, no light cream or low fat
