  • Butter: Adds moisture and richness. I use salted butter but feel free to use unsalted butter and add a pinch of salt to the cake batter.
  • Sugar: Sweetens the cake. Granulated sugar works best.
  • Egg White: An egg white adds lift and structure to the cake and helps bind the ingredients. Be sure to save the egg yolk and use it to make a French Breakfast Puff, Chocolate Chip Banana Bread, Thumbprint Cookies, or a Mini German Chocolate Cake.
  • Vanilla Extract: Enhances the flavor.
  • All-Purpose Flour: The base of the cake.
  • Unsweetened Cocoa Powder: Provides the chocolate flavor. Use Dutch-processed cocoa for a richer taste.
  • Baking Powder: Helps the cake rise and gives it a light, fluffy texture.
  • Baking Soda: Works with the baking powder to help the cake rise and improve texture.
  • Heavy Cream: Makes the cake incredibly moist. In a pinch, use half and half or whole milk instead.

Recipe Variations

This small chocolate cake recipe is wonderfully versatile. Here are a few variations to try:

  • Peanut Butter Chocolate Cake: Swirl in a teaspoon or two of peanut butter into the batter before baking.
  • Mint Chocolate Cake: Add a drop of mint extract to the batter for a refreshing twist.
  • Spicy Chocolate Cake: Add a pinch of cinnamon and cayenne pepper for a spicy kick.

Although we use a simple sprinkling of powdered sugar, you can also top this cake with buttercream frosting, chocolate frosting, cream cheese frosting, chocolate ganache, or homemade whipped cream for extra indulgence.

You can enjoy the cake right out of the ramekin or loosen the edges by running a knife around the edge of the cake. Place a plate on top of the ramekin and turn it over so that the cake slides right out.

Expert Tips

  • Measure Carefully: Accurate measurements ensure the best results.
  • Don’t Overmix: Mix until just combined to keep the cake tender.
  • Grease the Ramekin Well: Prevents sticking and makes it easier to remove the cake.
  • Check for Doneness: Insert a toothpick in the center; if it comes out clean, the cake is done.
  • Cool Before Dusting: Let the cake cool slightly before dusting with powdered sugar to prevent it from melting.
  • Serve Fresh: This cake is best enjoyed the day it’s made.

Frequently Asked Questions

How can I make chocolate cake for two?

If you’d like to make a small chocolate cake that serves two people, double the ingredient amounts and bake the cake in a 5×5 inch baking dish.

If I double this recipe, can I use the whole egg?

No, we don’t recommend using a whole egg if you double the recipe. For the best taste and texture, use two egg whites instead. You can save the egg yolks and use them in any of our recipes that call for egg yolks. Check out our Recipe Finder at the top of each page to find these recipes.

How will I know when the chocolate cake is done?

A toothpick inserted in the center should come out clean.

How should I store leftover chocolate cake?

This cake is best eaten fresh, but you can cover and keep the unfrosted cake on your counter for up to 2 days. No need to refrigerate.

    hi
    can I substitute bakers chocolate for cocoa powder? also any suggestions for adding coffee ie the amount?

    your recipes are awesome, I’m a senior living by yourself and I love to cook

    thanks

    1. Joanie Zisk says:

      Thank you so much! I’m glad you’re enjoying the recipes. For the chocolate cake, it’s best to use cocoa powder as it replaces some of the flour. You can add a bit of Baker’s chopped chocolate if you like, but make sure to keep the cocoa powder in the recipe. For adding coffee, replace 1 tablespoon of the heavy cream with coffee, so you’ll use 2 tablespoons of heavy cream and 1 tablespoon of coffee.
