Ingredients

2 cups all-purpose flour
2 cups granulated sugar
¾ cup unsweetened cocoa powder
1½ teaspoons baking powder
1½ teaspoons baking soda
1 teaspoon salt
1 cup whole milk
½ cup vegetable oil
2 large eggs
2 teaspoons vanilla extract
1 cup boiling water

Instructions

Preheat your oven to 350°F (175°C). Grease the 9×13-inch baking pan thoroughly with butter or non-stick spray, then lightly dust with cocoa powder or flour to prevent sticking.
In a large mixing bowl, whisk together the flour, sugar, cocoa powder, baking powder, baking soda, and salt until evenly combined.

Add the milk, vegetable oil, eggs, and vanilla extract to the dry ingredients. Mix on medium speed with an electric mixer or beat vigorously with a hand mixer for about 2 minutes until smooth and well combined.
Carefully stir in the boiling water. The batter will be thin—it’s normal and ensures a moist cake. Mix just until the water is incorporated; do not overmix.
Pour the batter into the prepared pan, spreading evenly with a spatula.

Bake in the preheated oven for 35-40 minutes. To check for doneness, insert a toothpick into the center; it should come out clean or with a few moist crumbs.
Remove the cake from the oven and allow it to cool in the pan for about 15 minutes. Then transfer it to a wire rack to cool completely before frosting or serving.

Tips

For a richer flavor, substitute buttermilk for the milk, or add a splash of coffee to enhance the chocolate depth.

To keep the cake moist longer, wrap it tightly in plastic wrap and store at room temperature for up to 2 days, or refrigerate for up to 5 days.
Be careful not to overmix the batter after adding the water; overmixing can lead to a dense cake.
If you want a more decadent cake, consider adding chocolate chips or chopped nuts into the batter before baking.

Serving Suggestions

This chocolate cake pairs beautifully with a dollop of whipped cream, a scoop of vanilla ice cream, or a drizzle of chocolate ganache. For a special occasion, top it with sprinkles, fresh berries, or a dusting of powdered sugar to elevate its presentation. It’s perfect served plain for a simple, satisfying dessert or dressed up for celebrations.

Variations

For a different twist, try adding a layer of fruit preserves or cream cheese frosting between two layers of this cake if you double the recipe. You can also incorporate flavors like peppermint extract, orange zest, or espresso powder into the batter for a unique flavor profile. For a gluten-free version, substitute the all-purpose flour with a gluten-free baking blend and ensure your other ingredients are gluten-free.

Storage and Reheating

Store leftovers in an airtight container at room temperature for up to 2 days. For longer storage, wrap the cake tightly in plastic wrap and refrigerate for up to 5 days. To reheat, microwave individual slices for 10-15 seconds until warm, or gently warm the entire cake in a low oven (around 300°F) for about 10 minutes. If the cake has been refrigerated, bring it to room temperature before serving for the best texture and flavor.

Frequently Asked Questions

Can I make this cake ahead of time?

Yes, you can prepare the cake a day in advance. Once cooled completely, wrap it tightly in plastic wrap and store at room temperature for up to 2 days. For longer storage, refrigerate it wrapped for up to 5 days. Frost or serve directly from storage.

Can I freeze this cake?

Absolutely. Wrap the cooled cake tightly in plastic wrap, then foil, and freeze for up to 3 months. To thaw, leave it at room temperature for a few hours. If you want to freeze individual slices, wrap each slice separately for easier serving later.

What type of frosting works best with this cake?

Chocolate buttercream, cream cheese frosting, or a simple dusting of powdered sugar all complement this cake well. For a lighter option, whipped cream with berries can also be delightful. Choose your frosting based on the occasion and your taste preferences.

Can I add nuts or other mix-ins?

Yes, folding in chocolate chips, chopped nuts, or dried fruit into the batter before baking adds texture and flavor. Just be sure not to overload the batter, which could affect baking time and cake structure.

How do I know when the cake is done?

The cake is ready when a toothpick inserted into the center comes out clean or with just a few moist crumbs attached. The edges should also start to pull away slightly from the sides of the pan. Avoid overbaking to keep it moist.
