Ingredients (just two!)
If you have any ingredients leftover from this mini 2-ingredient chocolate cake recipe, check out our Leftover Ingredients Recipe Finder.
- Egg: Acts as both the structure and leavening for the cake, giving it a light, rich texture.
- Semi-Sweet Chocolate: The key to flavor and texture. Use good-quality chocolate bars or baking chocolate, such as Ghirardelli, Guittard, or Lindt.
Measurement Tip: You’ll need about 2 ounces, which equals roughly ⅓ cup of chopped chocolate.
Two Easy Ways To Make A 2-Ingredient Chocolate Cake
You can make this simple chocolate cake using one of two methods. Both are easy and yield slightly different textures – one rich and fudgy, the other light and airy.
See the recipe box below for ingredient amounts and full recipe instructions.
Method 1: Separate the Egg (Recommended for a Fudgier Cake)
- Prepare the Eggs: Separate the yolk and white. Using an electric mixer or whisk, beat the egg white for about 2 minutes until soft peaks form.
- Mix Chocolate and Yolk: Melt the chocolate. In a separate bowl, whisk the melted chocolate with the egg yolk until smooth.
- Combine: Gently fold the whipped egg white into the chocolate mixture, keeping as much air in the batter as possible.
- Bake: Pour into a greased 10-ounce ramekin and bake at 350°F (177°C) for 20 minutes.
Texture: Rich, dense, and fudgy.
Method 2: Whisk the Whole Egg (For a Lighter Cake)
- Whisk the Egg: In a small bowl, whisk the entire egg (yolk and white together) for about 30 seconds until frothy.
- Add Chocolate: Stir in the melted chocolate until fully blended.
- Bake: Pour into a greased 10-ounce ramekin and bake at 350°F (177°C) for 20 minutes.
Texture: Soft and fluffy, similar to a classic sponge cake.
Expert Tips
- Separate Carefully: Make sure no yolk gets into the egg white. Even a small amount of yolk can prevent the whites from whipping properly.
- Fold Gently: Use a spatula to slowly fold the whipped egg whites into the chocolate mixture. Stirring too hard can deflate the batter and make the cake dense.
- Use Room Temperature Eggs: Cold eggs don’t whip as easily. Let your egg sit at room temperature for about 10 minutes before using.
- Check for Doneness: The cake is ready when the top looks set and slightly springs back when touched.
Serving Suggestions
This rich 2-Ingredient Chocolate Cake pairs beautifully with a variety of toppings and sauces to make it even more special. Try one of these favorites:
- Vanilla Ice Cream For One: Add a scoop for a classic warm-and-cold combination.
- Homemade Caramel: Drizzle over the top for a sweet, buttery finish.
- Small Batch Strawberry Pie Filling: Spoon on for a bright, fruity contrast to the deep chocolate flavor.
- Small Batch Chocolate Frosting: Spread a layer for extra richness.
- Small Batch Whipped Cream: Top with a dollop for a light, creamy touch.

Equipment
Ingredients
- 2 ounces semi sweet chocolate -coarsely chopped
- 1 large egg (yolk and white separated)
Instructions
- Heat the oven to 350°F (177°C).
- Place the chopped chocolate in a microwave-safe bowl and heat in 15-second intervals, stirring between each, until melted and smooth. Alternatively, melt the chocolate in a heatproof bowl set over a pot of simmering water, stirring constantly until glossy. Set aside to cool slightly.
- Separate the egg, placing the yolk in one bowl and the white in another.
- Whisk the egg yolk into the melted chocolate until smooth and fully combined.
- Using an electric mixer or whisk, beat the egg white for about 2 minutes, until soft peaks form.
- Gently fold the whipped egg white into the chocolate mixture until combined. Avoid overmixing so the batter stays light and fluffy.
- Pour the batter into a greased 10-ounce ramekin and bake for 20 minutes, or until set.
Notes
- Separate Carefully: Make sure no yolk gets into the egg white. Even a small amount of yolk can prevent the whites from whipping properly.
- Fold Gently: Use a spatula to slowly fold the whipped egg whites into the chocolate mixture. Stirring too hard can deflate the batter and make the cake dense.
- Use Room Temperature Eggs: Cold eggs don’t whip as easily. Let your egg sit at room temperature for about 10 minutes before using.
- Check for Doneness: The cake is ready when the top looks set and slightly springs back when touched.
Nutrition
The information shown is an estimate provided by an online nutrition calculator. It should not be considered a substitute for a professional nutritionist’s advice.
This recipe just says to fold in the whipped egg white, but I’m missing where it says to whip it. Should it be whipped to stiff peaks?
The egg white should be whipped to soft peaks before folding it in. That step is shown in the recipe post along with photos to guide you, and it’s listed as Steps 5 and 6 in the recipe instructions.
Crazy simple, wonderfully yummy, this is a keeper. So much for so little, love it!
