The Best Easy Chocolate Cake

By DreiFromBK

We wanted an easy chocolate mayonnaise cake recipe that would deliver good chocolate flavor. To get there, we “bloomed” unsweetened cocoa powder in coffee to intensify its flavor and supplemented it with bittersweet chocolate. Although traditional easy chocolate cake recipes are made with mayonnaise only, we found that adding an egg to the batter gave it moisture and a springy texture that we loved.

3. Scrape batter into prepared pan and smooth top. Bake until wooden skewer inserted into center of cake comes out with few crumbs attached, 30 to 35 minutes.

4. Let cake cool in pan on wire rack, 1 to 2 hours. Dust with confectioners’ sugar, cut into squares, and serve straight from the pan; or turn cake out onto serving platter and dust with confectioners’ sugar.
