This morning I tried it with whole wheat flour because I have 2 bags of whole wheat flour I really need to finish up. I reduced the sugar to 2 TBSP. I also didn't put in lemon zest (saving my lemons for espresso cheesecake, an Ina recipe of course, for Sydney's first birthday this weekend). I haven't found a recipe with lemon zest I didn't like by the way.
So with all the changes, it was a flop. Edible. But not as delicious as last night's batch. Sydney ate it reluctantly.
