I’ve made loads of other flourless chocolate cakes, some glazed like this La Bete Noire, others served with berries and cream like this Flourless Chocolate Cake from Princeville Hotel. But flourless chocolate desserts aren’t limited to cakes. These decadent Flourless Chocolate Turtle Cookies throw caramel and pecans into the delicious mix or how about a Flourless Chocolate Brownie topped with ice cream, chocolate sauce, and toasted coconut???

Tips for Making the Best Flourless Chocolate Cake
- Since there’s no flour (duh!) in a flourless chocolate cake, your taste buds are getting a pure blast of chocolate flavor. Undiluted, unadulterated. So for this reason, buy a step up in quality. Chocolate Bars instead of chocolate chips. A European brand if you dare.
- As far as domestic chocolate, I primarily use Ghirardelli bars. Watch for sales around the holidays and stock your cupboards.
- The same goes for butter. European butter rocks, but it does cost more. Kerrygold Irish Butter has a higher butterfat percentage compared to traditional grocery store butter and is readily available. It’s more important to buy quality chocolate, but if you want to spring for a top-notch butter, try a European brand.
- Read your recipe as some so-called flourless chocolate cakes actually have a couple of tablespoons of flour. You will not want to serve one of those recipes to your gluten-free guests or on Passover.
- Coffee enhances the flavor of chocolate. 1/2 cup of coffee will not make this cake taste like a mocha dessert but instead will make the chocolate flavor deeper, more intense.
- If you want even more chocolate intensity, use bittersweet chocolate instead of semisweet.
- Many flourless chocolate cakes have whipped egg whites folded into the chocolate and egg yolks to lighten the batter. In this particular cake, the leftover egg whites are whipped into a fluffy meringue, AKA marshmallow, frosting.
- As with any meringue, the most important tip is to have all your bowls and utensils free from oils, grease and any bits of egg yolk. Any of the former will prevent the whites from whipping into a beautiful, billowy marshmallow frosting.
- I’d recommend separating your eggs one at a time, using two bowls (meaning don’t separate a whole egg over the bowl of egg whites). If you happen to get a bit of yolk into those whites, all of them are contaminated and you have to start over. Trust me, I’ve done that. It’s a nightmare when you don’t have an extra 6 eggs to spare in the refrigerator!

- 2½ sticks butter, cut into pieces, plus more for the pan
