Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

Molasses Chocolate Cake

1/2 cup vegetable oil or melted butter
2 teaspoons vinegar
2 teaspoons vanilla extract
1/4 cup molasses
1 3/4 cups water
3 cups all-purpose flour, spooned and leveled
1 1/2 cups granulated sugar
6 tablespoons unsweetened cocoa powder
2 teaspoons baking soda
1 teaspoon salt

Secret Ingredient Chocolate Frosting

1/2 cup butter, softened or coconut oil
1/4 cup water or coconut milk
2 tablespoons molasses
1 teaspoon vanilla extract
3 cups icing sugar
3/4 cup unsweetened cocoa powder

Directions

Preheat the oven to 350°F (175°C). Line a 9 x 13 inch baking pan with parchment paper or lightly grease and flour two 8-inch round cake pans.

In a large mixing bowl, whisk together the flour, sugar, cocoa powder, baking soda, and salt until evenly combined.

In a separate medium bowl, whisk together the oil, vinegar, vanilla extract, molasses, and water until smooth.

Pour the wet ingredients into the bowl of dry ingredients. Whisk until the batter is smooth and fully combined with no dry pockets remaining.

Pour the batter into the prepared baking pan or divide evenly between the two round cake pans.

Bake for 35 to 40 minutes, or until the cake begins to pull away from the edges of the pan and a toothpick inserted into the center comes out clean.

Allow the cake to cool in the pan for about 10 minutes. Then remove it from the pan and transfer to a wire rack to cool completely before frosting.

For the frosting, place the softened butter or coconut oil in a mixing bowl and cream it with the molasses and vanilla extract until smooth.

Add the water or coconut milk and mix well until incorporated.

Stir in the cocoa powder, mixing until smooth.

Gradually add the icing sugar one cup at a time, beating well after each addition until the frosting becomes smooth, creamy, and spreadable.

Spread the frosting evenly over the completely cooled cake.

Variations

Layer cake version
Bake the batter in two 8-inch round pans. Once cooled, spread frosting between the layers and over the top for a classic layered chocolate cake.

Cupcake version
Divide the batter into lined muffin tins and bake for about 18 to 22 minutes. This version works great for parties and easy serving.

Extra chocolate flavor
Add 1/2 cup dairy-free chocolate chips to the batter for an even richer chocolate cake.

Mocha chocolate cake
Add 1 teaspoon instant coffee or espresso powder to the batter to deepen the chocolate flavor.

Nut topping
Sprinkle chopped walnuts or almonds on top of the frosting for extra texture and flavor.

Storage/Reheating

Store the frosted cake in an airtight container at room temperature for up to 3 days. The molasses helps the cake retain moisture, so it stays soft even after sitting for a while.

For longer storage, keep the cake in the refrigerator for up to 5 days. Allow it to come to room temperature before serving for the best texture.

You can also freeze the unfrosted cake layers. Wrap them tightly in plastic wrap and store in the freezer for up to 2 months. Thaw overnight in the refrigerator before frosting.

If reheating a slice, warm it in the microwave for about 10 to 15 seconds to restore its soft texture.

FAQs

Can I taste the molasses strongly in this cake?

No. The molasses enhances the chocolate flavor rather than overpowering it, adding a subtle richness and depth.

Why is vinegar used in this recipe?

Vinegar reacts with baking soda to help the cake rise and become light and fluffy, especially in egg-free baking.

Can I make this cake completely dairy-free?

Yes. Simply use vegetable oil in the cake and coconut oil instead of butter in the frosting.

What type of cocoa powder works best?

Unsweetened natural cocoa powder works perfectly and provides a balanced chocolate flavor.

Can I reduce the sugar?

You can slightly reduce the sugar, but reducing too much may affect the cake’s texture and moisture.

Can I use whole wheat flour instead of all-purpose flour?

You can substitute up to half of the flour with whole wheat flour, though the cake may become slightly denser.

How do I know when the cake is done baking?

Insert a toothpick into the center of the cake. If it comes out clean or with a few crumbs, the cake is ready.

Can I make the frosting ahead of time?

Yes. Store the frosting in the refrigerator for up to 3 days and allow it to soften slightly before spreading.

Can this cake be made into cupcakes?

Yes. Bake the batter in cupcake liners for about 18 to 22 minutes at the same temperature.

Why does this cake stay moist for days?

The molasses and oil in the recipe help retain moisture, keeping the cake soft and tender even after several days.
