Claudia Fleming’s original recipe called for 1/2 Tablespoon baking soda to be added to molasses/beer mix. Your recipe calls for /2 teaspoon. Whic

Hi Jonathan! Interesting note about teaspoon vs tablespoon—after doing a bit of digging, it seems like online reprints show both versions (e.g., Epicurious and Smitten Kitchen have 1/2 teaspoon, David Lebovitz has 1/2 tablespoon). With the amount of flour in the Gingeriest Gingerbread, the current quantity of baking soda and baking powder shouldn't cause any falling issues. Sorry that happened! I've run into fallen cakes when I've overmixed the batter, but found with the right amount of whipped cream on top, even too-dense cakes still taste delicious.

Answering my own question, sort of..upon reading Claudia Fleming’s recipe she notes that the oven must not be opened for at least an hour or the cake may fall. I did open the oven at around 30 minutes and turned the cake around. That is probably why it fell .
