Chocolate RumChata Cake


What sets this cake apart is the irresistible fluffy frosting. In all essence, it’s a whipped ganache, however, I add an extra dose of heavy cream to the ganache before it’s whipped to create extra volume. It’s creamy, extra fluffy and let’s not forget it’s punched up with RumChata cream liqueur for a blissful addition to the chocolate cake.

The cake itself is a one-bowl wonder made using hot boiling water. What the hot water does is give the leaveners a little extra push at the beginning by creating a warm environment. Most baking powders these days are double-acting, meaning they activate when in contact with moisture and again when exposed to heat. The cake rises up when baking but once removed from the oven the center will fall slightly to create a “fudgier” texture. The hot water also helps to dissolve the sugar and it brings out the chocolate flavour of the cocoa powder by hydrating it. Other reasons to use hot water include helping keep the cake moist and it creates a nice smooth crumb. This is one of my go-to cakes because of its simplicity, and I have no doubt it will be a favourite of yours as well. Enjoy!
