Rustic Single Layer Chocolate Cake Recipe

Single Layer Rustic Chocolate Cake

This single layer rustic chocolate cake is rich, deeply chocolaty, and wonderfully simple to make. It is an easy chocolate cake recipe with a homemade look, a tender crumb, and the kind of flavor that makes every slice feel special.

This cake has been a favorite with family and friends, and it is the kind of dessert that feels comforting without being complicated. The first time I made this single layer rustic chocolate cake, I was not completely sure how it would turn out. Recipe testing can take a few tries, and a cake needs to taste just right before it becomes one worth sharing.

This one passed the test right away. Everyone loved the rich chocolate flavor, the soft texture, and the fact that it was not overly sweet. It has become a cake I enjoy making again and again, especially because it uses simple everyday ingredients and does not require layers, frosting, or any fancy decorating.

One of the charming things about this chocolate cake is its rustic appearance. As you can see in the photos, the top may crack as it bakes. That is part of what gives the cake its homemade character. The first time I baked it, the cracked top caught my eye, but the flavor was so delicious that I did not want to change a thing.

That is why this recipe is called a rustic chocolate cake. It is not meant to look perfectly polished. It is meant to taste rich, moist, and satisfying. You can serve it plain, dust it lightly with powdered sugar, or add a glaze if you like. Even with a topping, it still keeps that beautiful simple, rustic look.

This cake is extra rich in flavor thanks to good quality semisweet or bittersweet chocolate. You do not need a large amount, but using chocolate you enjoy eating makes a difference in the final taste. Semisweet chocolate gives the cake a slightly sweeter flavor, while bittersweet chocolate creates a darker, deeper chocolate taste.

The batter contains no eggs or dairy. That was not the original goal, but the recipe simply did not need them for texture or flavor. Vegetable oil gives the cake moisture and keeps the crumb tender. The finished cake is perfect as a single layer dessert and does not need another layer, frosting, or glaze to feel complete.

If you want to dress it up, a dusting of powdered sugar looks elegant and simple. There is also an easy chocolate ganache glaze included below. However, try the cake at least once with nothing more than powdered sugar, or even completely plain. The rich chocolate flavor is delicious on its own.

How to Make This Rich Single Layer Rustic Chocolate Cake

Directions

1. Preheat the oven to 320 degrees F or 160 degrees C. Make sure the bottom and sides of a 9-inch springform pan fit together securely, and close the latch tightly.
2. Wrap foil under and around the outside of the springform pan, pressing it snugly against the bottom and sides. Spray the inside of the pan with cooking spray or baking spray. Line only the bottom with parchment paper, then spray the parchment as well. Line a rimmed baking sheet with foil and set it aside.
3. Place the chopped chocolate in a heatproof bowl. Pour the boiled water over the chocolate and stir until the chocolate is completely melted and smooth.
4. Add the 1/2 cup sugar and the additional 2 tablespoons sugar. Stir well until combined.
5. Add the vanilla extract and vegetable oil, then stir again until the mixture is smooth.
6. In a separate bowl, sift the flour with the baking powder and salt.
7. Add the flour mixture to the chocolate mixture. Stir gently until the dry ingredients are fully incorporated. Scrape down into the bowl as needed, but try not to overmix. The batter will be thin and pourable.
8. Pour the batter into the prepared springform pan. Place the pan directly on the lined baking sheet.
9. Bake for 45 to 60 minutes, checking after 45 minutes. The cake is done when the top springs back slightly when touched and a toothpick or wooden skewer inserted into the center comes out clean or with dry crumbs. The top may crack as it bakes, which is normal for this rustic chocolate cake.
10. Remove the cake from the oven and let it cool in the pan on a wire rack for about 30 minutes. Gently release the latch without fully opening the pan, then let the cake cool for another 15 minutes.
11. Run a butter knife carefully around the edges of the pan. Open the latch fully and remove the ring. Let the cake sit on the base for another 10 minutes.
12. Slide the butter knife gently between the bottom of the cake and the springform base to loosen it. Using a large spatula or your hands, carefully transfer the cake to a serving plate. Dust with powdered sugar if desired, slice, and enjoy.
