This chocolate snack cake recipe is soft, moist, and easy to make! It's soaked with chocolate syrup and topped with chocolate ganache. It's a chocolate lovers dream come true!
Start by making the chocolate ganache. Pour heavy into a medium mixing bowl. Microwave for 1 minute then add semi-sweet chocolate chips and butter. Let it sit for about 2 minutes, then whisk together until smooth. (If it's not fully melted, microwave in 15 second increments, whisking between each, until fully melted).
Preheat the oven to 350 degrees F. Line an 8x8 metal baking dish with parchment paper. Set aside.
In a large bowl, whisk together olive oil, sugar, and brown sugar for about 1 minute, until combined, then add eggs, egg yolk, sour cream, vanilla extract, and dutch process cocoa powder. 1/2 cup Olive Oil 1 cup Sugar2/3 cup Brown Sugar2 large Eggs1 Egg Yolk3/4 cup Sour Cream 1 tsp Vanilla Extract1 cup Dutch Process Cocoa Powder
Add in the flour, espresso powder, baking powder, baking soda, and kosher salt. Whisk together until just combined, then pour in hot coffee. Mix until smooth. 1 1/2 cups All Purpose Flour1 tsp Espresso Powder3/4 tsp Baking Soda3/4 tsp Baking Powder1 tsp Kosher Salt 2/3 cup Hot Coffee
Pour batter into the baking pan and bake for 55-60 minutes, until a toothpick inserted into the center of the cake comes out with just a few moist crumbs.
While the cake is baking, make the chocolate simple syrup. Combine water and sugar in a small saucepan over low heat. Cook until the sugar is dissolved, about 5-6 minutes, then remove from heat and whisk in cocoa powder and espresso powder. 1/2 cup Water1/2 cup Sugar2 tbsp Dutch Process Cocoa Powder1 tsp Espresso Powder
Let the cake cool in the pan for about 10 minutes, then poke holes into the cake with a toothpick and pour the chocolate simple syrup on top.
Allow the cake to cool completely in the pan then add the chocolate ganache on top.
Notes
Use high fat cocoa powder. You’ll need dutch process cocoa powder with high fat content, about 20-24% fat. (don’t worry, most dutch process cocoa powders have this, just check the label) This can make or break your cake! If you’ve ever made a chocolate cake and it was dry or chalky, it’s likely from the type of cocoa powder used. I swear by this dutch process cocoa powder, but use what you can find!
Weigh your ingredients with a kitchen scale. Weighing your ingredients will yield the most consistent results and prevents adding too much (or too little) ingredients which can throw off the texture of the cake. I provide the gram measurements in the recipe card.
Don’t overmix the batter. Mix just until combined to keep the cake tender. Overmixing can cause gluten to form and leads to a tough cake.
Overbaking the cake. Chocolate cakes dry out quickly if baked too long! Everyone’s oven is a little different so start checking the cake about 5 minutes before the recommended baking time.
