👩‍🍳 Instructions

1. Prepare the Oven and Pan

Preheat your oven to 350°F (175°C).

Grease a 9-inch (23 cm) round cake pan and line the bottom with parchment paper.

For especially easy removal, lightly grease the parchment as well.

2. Melt the Dark Chocolate

Place the 150g chopped dark chocolate in a heatproof bowl.

Pour about ½ cup of the hot water over the chocolate and let it sit for 1–2 minutes.

Whisk gently until the chocolate has completely melted and the mixture is smooth.

Set aside to cool slightly.

Tip: The chocolate mixture should be warm and fluid, but not piping hot when added to the batter.

3. Combine the Dry Ingredients

In a large bowl, whisk together:

Flour
Brown sugar
Cocoa powder
Baking powder
Baking soda
Salt

Break up any lumps of brown sugar or cocoa powder.

4. Mix the Wet Ingredients

In a separate bowl, whisk together the:

Eggs
Vegetable oil
Milk
Vanilla extract

Whisk until smooth and evenly combined.

5. Make the Batter

Pour the wet mixture into the bowl of dry ingredients.

Add the melted chocolate mixture.

Using a whisk or spatula, gently mix until the batter is smooth.

Do not overmix.

The batter will be fairly thick at first.

6. Add the Hot Water

Gradually pour in the remaining ½ cup hot water, mixing gently as you go.

The batter will become noticeably thinner and glossy.

This is completely normal.

The hot liquid helps bloom the cocoa and creates the exceptionally moist, fudgy texture characteristic of a mud cake.

7. Pour Into the Pan

Pour the batter into the prepared cake pan.

Gently tap the pan against the counter once or twice to release any large air bubbles.

Smooth the surface with a spatula.

8. Bake

Place the cake in the center of the preheated oven.

Bake for approximately 45–55 minutes.

The cake is ready when:

The center is set but still slightly soft
The top looks glossy and slightly cracked
A toothpick inserted into the center comes out with a few moist crumbs, rather than completely clean

Do not overbake—the cake should remain moist and fudgy in the center.

9. Cool the Cake

Remove the cake from the oven and allow it to cool in the pan for 15–20 minutes.

Run a thin knife around the edge, then carefully turn the cake onto a wire rack.

Allow it to cool completely before adding the ganache.

For the cleanest slices and richest texture, chill the cooled cake for about 30 minutes before glazing.

10. Heat the Cream

Place the heavy cream in a small saucepan.

Heat over medium-low heat until it is hot and steaming, with small bubbles beginning to appear around the edges.

Do not bring it to a vigorous boil.

11. Add the Chocolate

Place the chopped dark chocolate in a heatproof bowl.

Pour the hot cream over the chocolate.

Let it sit undisturbed for 2–3 minutes.

Then slowly whisk from the center outward until the chocolate melts completely and the ganache becomes smooth, glossy, and silky.

12. Add Butter

If using, stir in 1 tablespoon butter until completely melted.

The butter gives the ganache an especially smooth texture and beautiful shine.

Allow the ganache to cool for 10–15 minutes, stirring occasionally, until it thickens slightly but remains pourable.

🎂 Assemble the Cake

13. Glaze the Cake

Place the cooled cake on a serving plate or cake stand.

Pour the ganache over the center of the cake.

Use an offset spatula to gently spread it toward the edges, allowing some ganache to naturally drip down the sides.

For a perfectly smooth finish, leave the top slightly glossy.

14. Decorate

Finish with your choice of:

Chocolate curls or shavings
Fresh berries
Chopped nuts
Cocoa powder
Flaky sea salt

Allow the ganache to set for 20–30 minutes before slicing.

For an even firmer chocolate topping, refrigerate the cake for about 1 hour.

⭐ Chef’s Tips

Don’t overbake: The secret to mud cake is its moist, dense center. Remove it when a toothpick still has a few moist crumbs attached.

Use good-quality chocolate: Since chocolate is the star ingredient, a good dark chocolate makes a noticeable difference.

Bloom the cocoa: Combining cocoa with hot liquid intensifies its chocolate flavor.

Don’t worry about thin batter: Once the hot water is added, the batter becomes quite loose. That’s exactly what you want.

Cool completely before ganache: Warm cake will cause the ganache to melt and slide off.

For the richest flavor: Let the finished cake rest overnight in the refrigerator. The texture becomes even more fudgy and the chocolate flavor deepens.

For clean slices: Dip a sharp knife into hot water, wipe it dry, and slice. Clean and reheat the knife between cuts.

🍓 Delicious Variations

Salted Chocolate Mud Cake

Sprinkle flaky sea salt over the ganache while it is still soft.

Raspberry Chocolate Mud Cake

Add fresh raspberries on top and serve each slice with raspberry sauce.

Mocha Mud Cake

Add 2 teaspoons instant espresso powder to the dry ingredients for a deeper chocolate-coffee flavor.

Orange Chocolate Mud Cake

Add 1 tablespoon finely grated orange zest to the wet ingredients.

Peanut Butter Chocolate Cake

Swirl ½ cup creamy peanut butter over the batter before baking, or drizzle warmed peanut butter over the finished ganache.

Triple Chocolate Mud Cake

Fold ½ cup chocolate chips into the batter before baking and finish with extra chocolate curls.

🍽️ Serving Suggestions

This cake is delicious served at room temperature, but it is especially indulgent slightly chilled.

Serve with:

Vanilla ice cream
Lightly sweetened whipped cream
Fresh berries
Raspberry or strawberry sauce
A drizzle of warm chocolate sauce
Freshly brewed coffee or espresso

For an extra-decadent dessert, warm an individual slice for 10–15 seconds in the microwave and serve with a scoop of vanilla ice cream.

🧊 Storage

Cover the cake tightly and store it in the refrigerator for up to 5 days.

Because the ganache firms when chilled, allow the cake to sit at room temperature for 20–30 minutes before serving for the softest texture.

❄️ Freezing

The finished cake can be frozen for up to 2 months.

For best results:

Chill the cake until the ganache is firm.
Wrap tightly in plastic wrap.
Add a second layer of foil or place in an airtight freezer container.

Thaw overnight in the refrigerator.
Bring to room temperature before serving.

Individual slices can also be wrapped and frozen separately.

🍫 Final Result

This Chocolate Mud Cake delivers everything a chocolate dessert should be: deeply chocolatey, moist, dense, fudgy, and incredibly indulgent.

The combination of cocoa, melted dark chocolate, and a silky ganache creates a luxurious cake that tastes like it came straight from a professional bakery.

One slice is never enough. 🍫✨
