Madeleines top the list. (I think we have 6 pans).
Toll House (some with walnuts, some with pecans), Bourbon Balls, Butter Nut Balls, Lace Cookies and various Brownies and Fudge are in the running. Somewhere I have an old Danish cookbook with incredible recipes.
Another favorite is Almond cake (recipe on pkg of almond paste), baked in a flan pan, the indented part then filled with fresh berries and freshly whipped cream.
Champagne, of course negates *all* the butter, so Cheers!!
And we adore the people who send us Leonidas chocolates, Yoku Moku cookies and this year-- The Fourteener from Telluride Truffle.
