As we've mentioned before, there's a "national day" for everything. Even for chocolate eclairs!
My mom loved these things though I haven't had one in years. Here are several recipes for various chocolate eclair-oriented desserts from cooks.com, including Chocolate Eclairs, Chocolate Eclair Cake, and Cream Puffs.
Of course, if you're trying to eat well, this isn't your week. With this and National Ice Cream Soda Day in the same week, it's all much too tempting. Though we don't need a holiday to eat food like this. You can always start that diet next week, right?
