Again with the chocolate rye cake fromSarah Kieffer’s 100 Morning Treats. I’m posting this cake for the second time in a short while, as I have a question for more experienced bakers.
This is my third bake of this recipe (love the cake). The first came out fine, and today’s came out fine. The bake in between, however, sank.
The only difference I’m aware of is that for that failed, second bake, I swapped a little over half the Valrhona Dutch processed cocoa powder for KAF’s black cocoa powder, with no adjustments to the baking powder or the baking soda. Could that have resulted in the cake sinking?
Or is it more likely I mis-weighed or measured an ingredient somewhere?
My only other thought is my batter might have been too hot? This is one of those cakes where you melt the butter on the stove in a pot, and then start adding in all the rest of the ingredients to the warm pot. Most of the additions are made off heat, but still… Today I made sure to keep things at the lowest possible temp, yet still blend-able.
That sunken cake tasted fine, and the crumb was fine, but it had a large crevice - way beyond the ordinary crack down the middle of the top.
Any thoughts? Photos are of today’s, successful bake.
