Why does the middle of cakes rise more than the sides?

Just in case you were wondering, Kirsten asked the same thing! Do you think it’s the right answer?

    The quick & dirty answer is this ;D –>

    Because the sides are in direct contact with the metal (hooray for good conductors), they tend to cook quickly. This doesn’t allow time for chemical reactions to occur completely. As compared to the happy middle where more CO2 chemical happiness is made because the heat cooks it more slowly.

    Hope that’s what you were looking for. YAY you called me a scientist ❤ !!!

    oh snap! Seeing this again has inspired me to do an experiment next time i bake cupcakes. I’m going to bake some in paper cups + metal tins, and bake others just in the paper and compare them!!!

    • please post your findings! i would imagine that they would be both the same because i think the metal tins maybe lined with thin paper. i could be wrong though bwahha.
