A great choice to serve with coffee or tea. Adapted from Bon Appetit magazine. This has a very mild lemon flavor and is not overly sweet- if you prefer more of a lemony punch, add a teapsoon of lemon flavor extract along with the vanilla.

i don't know why this didn't work, i've been cooking bon appetit recipes for 25 years or more-- the topping melted into the rest of the cake which basically tastes like a lemon cinammon cake- nice flavor, i did cover the top with confectioners sugar but this is pretty plain- if i knew the topping would just blend in with the rest i wouldn't have bothered to separate it. i think if you separately blend some flour, lemon zest butter and cinammon it would have come out better

Absolutely delicious! Wonderful cinnamon flavour with a hint of lemon. I made this exactly according to the directions. I had no problem with the topping melting into the cake. It made a nice crunchy topping. It rises beautifully and is so moist! I did not dust with icing sugar, as my dh doesn't like it, but it still looked great! Thanks Heather!
