Healthy Chocolate Cake

Craving a slice of rich, decadent chocolate cake but watching your waistline? This Healthy Chocolate Cake is your answer! It delivers all the chocolatey goodness you desire without the excess sugar and unhealthy fats found in traditional recipes. We use whole wheat flour for added fiber, unsweetened applesauce for moisture, and just the right amount of sugar for a perfectly balanced sweetness. This Healthy Chocolate Cake recipe is a delicious way to satisfy your sweet tooth without the guilt.
I’ve always been a firm believer that healthy eating doesn’t mean sacrificing flavor. This recipe is a testament to that belief. It’s been a favorite in my kitchen for years, and I’m so excited to finally share it with you. This moist and flavorful cake is perfect for any occasion.
How to Make It (Overview)
Making this healthy chocolate cake is a straightforward process that results in a moist and flavorful treat. We begin by combining all the dry ingredients in one bowl and the wet ingredients in another. This ensures even distribution of flavors and leavening agents.
The next step involves gradually combining the wet and dry ingredients, taking care not to overmix. This prevents the development of excess gluten, which can make the cake tough.
A key element of this recipe is the addition of boiling water. This “blooms” the cocoa powder, intensifying its chocolate flavor and creating a moist, tender crumb. The batter will be quite thin after this addition.
Finally, the batter is poured into a prepared pan and baked until a toothpick inserted into the center comes out clean. Cooling the cake completely before frosting is crucial for preventing the frosting from melting.
Make Ahead Method
This healthy chocolate cake can be made ahead in several ways:
- Cake Layers: You can bake the cake layers a day or two in advance. Let them cool completely, then wrap them tightly in plastic wrap and store them at room temperature or in the refrigerator. For longer storage (up to 2 months), wrap the layers in plastic wrap, then in foil, and freeze them. Thaw overnight in the refrigerator before frosting.
- Frosting: If you’re using a homemade frosting, you can prepare it a day or two ahead and store it in an airtight container in the refrigerator. Bring it to room temperature and re-whip it slightly before frosting the cake.
- Assembled Cake: You can assemble and frost the entire cake a few hours before serving. Store it in the refrigerator until ready to serve. However, keep in mind that the cake is at its peak freshness when served the same day it’s baked.
Pro Tips
- Use high-quality cocoa powder: This will significantly impact the flavor of your cake. Dutch-processed cocoa powder, in particular, offers a richer, darker, and less acidic chocolate flavor compared to natural cocoa powder.
- Measure flour correctly: Spoon the flour into the measuring cup and level it off with a straight edge (like the back of a knife). Avoid scooping the flour directly from the bag, as this can compress it and result in too much flour, leading to a dry cake.
- Don’t overmix: As mentioned earlier, overmixing develops gluten and results in a tough cake. Mix until the ingredients are just combined.
- Use a toothpick or cake tester to check for doneness: This is the most reliable way to determine if your cake is fully baked.
- Let the cake cool completely: This prevents the frosting from melting and makes the cake easier to handle and frost.
Storage
Storing Leftover Cake:
- Unfrosted Cake: Store unfrosted cake layers tightly wrapped in plastic wrap at room temperature for up to 2 days or in the refrigerator for up to a week.
- Frosted Cake: Store frosted cake in an airtight container at room temperature for up to 3 days or in the refrigerator for up to a week. If the frosting is particularly delicate (like whipped cream frosting), refrigeration is highly recommended.
- Freezing Cake: You can freeze frosted or unfrosted cake. Wrap it tightly in plastic wrap, then in a layer of aluminum foil, and freeze for up to 2 months. Thaw overnight in the refrigerator before serving.

FAQs!
- Can I use all-purpose flour instead of whole wheat flour? Yes, you can substitute all-purpose flour. The texture will be a bit lighter and less dense, and the cake will have less fiber. You may want to reduce the liquid slightly if using all-purpose flour.
- Can I use a different type of oil? Yes, you can use melted coconut oil, canola oil, or another neutral-flavored vegetable oil.
- Can I make this into cupcakes? Yes, you can easily adapt this recipe for cupcakes. Fill cupcake liners about 2/3 full and bake for 18-20 minutes, or until a toothpick inserted into the center comes out clean.
Healthy Chocolate Cake
Ingredients
- 1 3/4 cups whole wheat flour
- 3/4 cup unsweetened cocoa powder
- 1 1/2 teaspoons baking powder
- 1 teaspoon baking soda
- 1/4 teaspoon salt
- 1 cup unsweetened applesauce
- 1 cup granulated sugar
- 2 large eggs
- 1/2 cup milk
- 1/4 cup vegetable oil
- 1 teaspoon vanilla extract
- 1 cup boiling water
Instructions
Preheat and Prepare the Pan(s):
- Preheat your oven to 350°F (175°C). Grease and flour a 9×13 inch baking pan thoroughly. This means coating the entire inside surface of the pan with a thin, even layer of shortening, butter, or cooking spray, followed by a light dusting of flour. This crucial step prevents the cake from sticking to the pan and ensures a clean release after baking. If you are making a two-layer cake, grease and flour two 9-inch round cake pans. For extra insurance against sticking, especially with round pans, you can also line the bottoms with parchment paper circles cut to fit.
Combine the Dry Ingredients:
- In a large mixing bowl, whisk together 1 3/4 cups whole wheat flour, 3/4 cup unsweetened cocoa powder, 1 1/2 teaspoons baking powder, 1 teaspoon baking soda, and 1/4 teaspoon salt. Use a whisk to thoroughly combine these dry ingredients. This step is essential for even distribution of the leavening agents (baking powder and baking soda), which ensures a consistent rise and texture throughout the baked cake. Whisking also helps to break up any clumps in the cocoa powder, preventing pockets of concentrated cocoa flavor in the finished cake.
Combine the Wet Ingredients:
- In a separate, medium-sized mixing bowl, combine 1 cup unsweetened applesauce, 1 cup granulated sugar, 2 large eggs, 1/2 cup milk (any type of milk—dairy, almond, soy, oat, etc.—will work well), 1/4 cup vegetable oil, and 1 teaspoon pure vanilla extract. Whisk these wet ingredients together thoroughly until they are well combined and the granulated sugar is mostly dissolved. The unsweetened applesauce serves as a natural sweetener and adds significant moisture to the cake, allowing you to use less added sugar and oil compared to traditional chocolate cake recipes.
Combine Wet and Dry Ingredients (with Care):
- Gradually add the dry ingredients to the wet ingredients. Add about one-third of the dry mixture at a time to the wet mixture. Mix on low speed with an electric mixer or by hand using a whisk or spatula until the ingredients are just combined. It’s extremely important not to overmix the batter. Overmixing develops the gluten in the whole wheat flour, resulting in a tough, dense, and dry cake. A few streaks of flour are perfectly acceptable at this stage; they will be incorporated during the next step.
Add the Boiling Water (and Mix Gently):
- Carefully pour 1 cup of boiling water into the batter. Stir gently but thoroughly with a spatula or whisk until the batter is smooth and all the ingredients are fully incorporated. The batter will be quite thin and almost watery after adding the boiling water; this is perfectly normal. The hot water helps to “bloom” the cocoa powder, which intensifies its chocolate flavor and contributes to a more moist and tender cake crumb.
