Chocolate Earthquake Cake
This Chocolate Earthquake Cake is a rich, tasty cake that is supposed to sink in the middle! Topped with ganache, whipped cream, and berries, it’s as picture-perfect as delicious.
I created this recipe with a group of blogger friends under the theme of hometown favorites. For those of you who know I grew up in Iowa, this may puzzle you. I couldn’t come up with a dessert featuring corn, soybeans or beef, so I took a little liberty…
Chocolate Earthquake Cake
Wondering why this Chocolate Earthquake Cake is a hometown favorite? My dad was a physics professor at Iowa State University, often referred to as Moo U. An idyllic little university town, we lived just blocks away from the campus. But my father had wanderlust. He grew up on the near north side of Chicago and loved nothing better than our summer vacations hiking in Aspen or camping in the National Parks out west.
When I was a junior in high school, he thought we should pack up our worldly possessions and spend a sabbatical year at the University of British Columbia in Vancouver. Oh, the drama this caused with his 4 daughters—a lot of estrogen in play. But it was like a dream vacation–sailing on English Bay in the summer, skiing on Grouse Mountain in the winter. And learning how to say about properly and punctuate sentences with “eh.”
And here comes my logic. Being on the west coast of the continent, Vancouver does experience tremors—and so my Chocolate Earthquake Cake now fit the hometown theme. Granted, I never felt an earthquake in Vancouver, though I have in Iowa, but work with me here!!!
A Retro Chocolate Cake Recipe
My mom baked up the first chocolate earthquake cake I ever sampled. Eggs were separated and the whites were beaten till light and fluffy. When the whites were folded into the chocolate batter and baked, they provided the lift to the otherwise non-leavened cake. But as it cooled, it was destined to crack and fall, thus becoming evidence of the fallout from a natural disaster! I figured this recipe from Ina Garten would work well. She talks about the sunken area in the middle of the cake to be filled with chocolate ganache.
In actuality, mine barely sank, but the ganache, and then whipped cream and raspberry topping really played well off the dense, rich cake whether needed to disguise any malformations or not! I took this cake to a holiday luncheon and my hostess, who is gluten-free, loved that this chocolate earthquake cake recipe only had a tablespoon of flour. Using a gluten-free substitute, like Cup4Cup, would turn this into a wonderful gluten-free dessert. You might also like this Chocolate Souffle Cake.
