Step-by-Step Instructions
1. Prepare Your Pan and Oven
Preheat your oven to 350°F (175°C). Lightly grease and flour a 9×13 inch baking pan. This prevents sticking and ensures a clean release for your one bowl cake.
2. Combine Dry Ingredients
In a large mixing bowl, whisk together the flour, cocoa powder, granulated sugar, baking soda, baking powder, and salt. Make sure there are no lumps; this is crucial for a smooth cake batter.
3. Add Wet Ingredients
Pour in the milk, vegetable oil, eggs, and vanilla extract into the same bowl. Whisk everything together until just combined. Don’t overmix, as this can make your cake tough.
4. Incorporate Hot Water and Chocolate Chips
Carefully stir in the hot water until the batter is smooth. This helps activate the cocoa and creates a fudgy texture for your one bowl cake. Gently fold in the chocolate chips.
5. Bake the Cake
Pour the batter into your prepared baking pan. Bake for 28-32 minutes, or until a wooden skewer inserted into the center comes out with moist crumbs. Avoid overbaking to keep it fudgy.
6. Cool and Serve
Let the cake cool in the pan on a wire rack for at least 15 minutes before slicing. You can then serve it warm or at room temperature. Enjoy your delicious one bowl double chocolate fudgy cake!
Variation Ideas
- Mint Chocolate: Add ½ teaspoon peppermint extract with the vanilla for a festive twist.
- Coffee Infusion: Replace hot water with hot brewed coffee to deepen the chocolate flavor.
- Nutty Crunch: Fold in ½ cup chopped pecans or walnuts with the chocolate chips.
- Cream Cheese Swirl: Dollop softened cream cheese (mixed with a little sugar and vanilla) onto the batter before baking and swirl with a knife.
Storage Instructions
Store leftover one bowl double chocolate fudgy cake in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate for up to a week. To enjoy warm, you can gently microwave individual slices for 10-15 seconds.
