Key Ingredients & Substitutions
- All-Purpose Flour: You can use a gluten-free all-purpose flour blend for a gluten-free option.

- Unsweetened Cocoa Powder: Dutch-processed cocoa powder will give a darker color and milder chocolate flavor.
- Baking Soda & Baking Powder: Essential for a fluffy texture.
- Salt: Balances the sweetness.
- Eggs: Large eggs work best; you can use flax eggs (1 tbsp ground flaxseed + 3 tbsp water per egg) as a vegan substitute.
- Milk: Any dairy or non-dairy milk (almond, soy, oat) works well.

Step-by-Step Instructions
1. Prepare Your Pan and Oven
Preheat your oven to 350°F (175°C). Grease and flour a 9×13 inch baking pan thoroughly. This prevents the cake from sticking.
2. Combine Dry Ingredients
In a large mixing bowl, whisk together the flour, sugar, cocoa powder, baking soda, baking powder, and salt. Make sure there are no lumps in the dry mixture.
3. Mix Wet Ingredients
Add the eggs, milk, vegetable oil, and vanilla extract to the dry ingredients. Beat with a whisk or electric mixer on medium speed for about 2 minutes until just combined. Do not overmix.
4. Incorporate Boiling Water
Carefully pour the boiling water into the batter. Mix until the batter is smooth and a little thin. This step is crucial for the cake’s moist texture and rich chocolate flavor.
5. Bake the Cake
Pour the batter into your prepared baking pan. Bake for 30-35 minutes, or until a wooden skewer inserted into the center comes out clean. Avoid opening the oven door too early.
6. Cool and Frost
Let the cake cool completely in the pan on a wire rack before frosting. This prevents your frosting from melting. Once cool, you can apply your favorite chocolate frosting or ganache.
Variation Ideas
- Coffee Infusion: Add 1-2 teaspoons of instant espresso powder to the dry ingredients for a mocha flavor.
- Mint Chocolate: Stir in ½ teaspoon of peppermint extract with the vanilla for a festive twist.
- Nutty Crunch: Fold in ½ cup of chopped walnuts or pecans before baking.
- Sheet Cake: This recipe works perfectly as a delicious sheet cake, ideal for gatherings.
Storage Instructions
Store your One-Bowl Chocolate Fudge Cake at room temperature in an airtight container for up to 3 days. If frosted with a dairy-based frosting, refrigerate it for up to 5 days. For longer storage, you can freeze individual slices, wrapped tightly, for up to 2 months.
