Chocolate Custard Cake Ingredients
For the Cake Layers

• Vegetable Oil – Keeps the cake moist; feel free to use olive oil for a healthier approach.

Step‑by‑Step Instructions for Chocolate Custard Cake
Step 1: Prepare Oven and Pans
Start by preheating your oven to 350°F (175°C). While it’s heating up, generously grease two 8-inch round cake pans with dairy-free butter or oil to ensure an easy release. Make sure to have parchment paper at the bottom of the pans for added security against sticking.
Step 2: Curdle Milk
In a small bowl, combine one cup of milk with a tablespoon of white vinegar, stirring gently. Let the mixture sit for about 5 minutes until it thickens slightly, giving you a homemade buttermilk substitute that will add moisture to your Chocolate Custard Cake. This step is crucial for developing the right texture.
Step 3: Mix Wet Ingredients
In a large mixing bowl, whisk together the curdled milk, ½ cup vegetable oil, and 1 cup cane sugar until the sugar dissolves completely. You can add a teaspoon of vanilla extract at this stage for an added depth of flavor. Make sure the mixture looks smooth and homogenous before moving on to the next step.
Step 4: Combine Dry Ingredients
Sift together 1 ½ cups of all-purpose flour, ¾ cup Dutch processed cocoa powder, 1 teaspoon baking soda, 1 teaspoon baking powder, and a pinch of salt in a separate bowl. Gradually mix this dry ingredient blend into the wet mixture, using a spatula to fold gently until fully incorporated. You want a smooth batter, free of lumps.
Step 5: Add Liquid
Carefully pour in 1 cup of boiling water or freshly brewed coffee into the batter. Stir the mixture continuously until it becomes beautifully smooth and glossy. The heat from the liquid will enhance the chocolate flavor, making your Chocolate Custard Cake decadent and rich.
Step 6: Bake Layers
Divide the batter evenly between the prepared cake pans and use a spatula to smooth the tops. Bake in your preheated oven for 25-30 minutes, or until a toothpick inserted into the center comes out clean. Once done, remove the pans from the oven and allow them to cool completely on a wire rack before lifting the layers out.
Step 7: Make Custard
In a medium saucepan, combine 1 cup chocolate milk, ⅔ cup sugar, ¾ cup cocoa powder, and 2 tablespoons cornstarch. Heat the mixture over medium heat, stirring constantly until it thickens, which should take about 8-10 minutes. Keep cooking for an additional 2-3 minutes until it reaches a glossy, pudding-like consistency.
Step 8: Finish Custard
Remove the custard from heat and stir in 2 tablespoons of unsalted butter, 1 teaspoon vanilla extract, and a pinch of salt until melted and smooth. Add in 4 ounces of dark chocolate, mixing until fully combined. Transfer to a bowl and refrigerate for 2-3 hours, allowing it to firm up before assembly.
Step 9: Assemble Cake
Once the cake layers have cooled completely, level the tops if needed. Place one layer on a serving plate and spread a generous amount of cooled chocolate custard on top. Gently place the second layer on top and crumb coat the entire cake with any remaining custard, then chill it in the refrigerator for about 30 minutes to set the layers.
Step 10: Chill Again
After your Chocolate Custard Cake has firmed up, apply a final layer of custard over the entire cake for a smooth finish. Refrigerate for an additional 30 minutes, ensuring the custard is perfectly set before slicing. This chilling step guarantees a perfect presentation and texture when serving your decadent cake.

Chocolate Custard Cake Recipe FAQs
How do I select the best ingredients for my Chocolate Custard Cake?
Absolutely! When selecting ingredients, opt for high-quality cocoa powder and dark chocolate (55-60%) for a rich flavor. Choose a milk alternative that you enjoy, like almond or oat milk, especially if you’re going for a dairy-free version. Ensure your cake flour is fresh for the best texture and don’t use flour that is past its expiry date.
Can I store my Chocolate Custard Cake and for how long?
Very! Store your Chocolate Custard Cake in an airtight container in the refrigerator for up to 3 days. It’s essential to let it sit at room temperature for 10-15 minutes before serving to allow the flavors to develop and the textures to soften adequately.
What are the freezing instructions for the Chocolate Custard Cake?
For freezing, I recommend wrapping individual slices tightly in plastic wrap and placing them in a freezer-safe bag. This will keep them fresh for up to 2 months. When you want to enjoy a slice, simply remove it from the freezer and let it thaw in the refrigerator overnight, or reheat for about 15-20 seconds in the microwave for a cozy treat!
What if my chocolate custard turns out runny?
Don’t worry! If your custard ends up too runny, it’s often due to undercooking or not allowing it to thicken enough. To troubleshoot, you can return the custard to medium heat, continue stirring, and cook for another 2 to 3 minutes until it thickens. Also, make sure to measure your cornstarch precisely and allow it to mix thoroughly. If it thickens too much, whisk in a teaspoon of water or milk to adjust the consistency.
Is this Chocolate Custard Cake safe for people with allergies?
Of course! To make it suitable for various dietary needs, you can easily adapt this recipe. Use dairy-free butter and milk alternatives for those avoiding dairy. For a vegan twist, ensure that your chocolate is dairy-free as well. Just keep in mind to check for any potential allergens in the ingredients you choose. It’s always best to confirm with your guests about any allergies beforehand.
How should I prepare the cake if I want to make it gluten-free?
No problem! To make your Chocolate Custard Cake gluten-free, simply substitute all-purpose flour with a gluten-free flour blend. Follow the same measurements as noted in the recipe. It’s important to ensure that all other ingredients, especially the baking powder and chocolate, are also gluten-free. Enjoy your baking adventure!
