Ingredients for Your Chocoflan Surprise Cake
- For the cake:
- 1 chocolate cake mix box
- 3 eggs
- ½ cup of oil
- 1 cup of water
- For the flan:
- 1 can of condensed milk
- 1 can of evaporated milk
- 4 eggs
- 1 teaspoon of vanilla essence

- 1 cup of sugar
Substitution Options for Flexibility
If you’re out of certain ingredients or want to experiment, here are some swaps:

Step-by-Step Guide to Making Your Chocoflan
Step 1: Prepare the Caramel
Start by melting the sugar in a pan over medium heat. Watch closely as it transforms into a golden amber liquid—this is your caramel. Pour it into the bottom of your mold quickly before it hardens. The smell alone will have your taste buds tingling. Let it cool while you prepare the rest.
Step 2: Mix the Cake Batter
Follow the instructions on the cake mix box, adding eggs, oil, and water. Whisk until smooth and pour it over the cooled caramel. The contrast between the dark caramel and light batter is already making your kitchen look like a bakery!
Step 3: Blend the Flan Mixture
In a blender, combine condensed milk, evaporated milk, eggs, and vanilla. Blend until silky smooth. Gently pour this mixture over the cake batter. Don’t worry if they seem to mix—it’s supposed to happen!
Step 4: Bake in a Water Bath
Cover the mold with foil and place it inside a larger tray filled halfway with hot water. This water bath ensures even cooking and prevents cracking. Bake at 350°F for 1 hour and 15 minutes. Insert a toothpick into the flan layer to check doneness—it should come out clean.
Step 5: Cool, Chill, and Unmold
Let the cake cool completely, then refrigerate for at least 4 hours. Run a knife around the edges before flipping it onto a plate. Voilà—a beautiful, layered masterpiece!
Pro Tip: Enhance Your Cake
To take your Chocoflan Surprise Cake to the next level, toast some chopped nuts and sprinkle them on top. A drizzle of extra caramel or whipped cream adds a luxurious finish.

Fun Fact About Chocoflan
This dessert is often called “pastel imposible” because of its magical separation during baking. Even seasoned bakers marvel at how the layers form so effortlessly.
Necessary Equipment
- Bundt pan or round cake mold
- Blender
- Large roasting pan (for water bath)
- Foil
Storage Tips
Store leftovers in an airtight container in the fridge. This keeps the cake moist and prevents it from absorbing odors. It stays fresh for up to 3 days.
If freezing, wrap individual slices tightly in plastic wrap and aluminum foil. They’ll last for up to a month. Thaw overnight in the fridge before serving.
Avoid leaving the cake at room temperature for more than two hours to prevent spoilage.
Tips and Advice
- Use a high-quality cake mix for better flavor.
- Blend the flan mixture thoroughly to avoid lumps.
- Make sure the water bath isn’t too hot to prevent curdling.
Presentation Ideas
- Garnish with fresh berries for a pop of color.
- Serve with a dollop of whipped cream on the side.
- Dust powdered sugar on top for an elegant touch.
Healthier Alternatives
Here are six ways to lighten up your chocoflan:
- Low-fat version: Use low-fat condensed and evaporated milk.
- Gluten-free: Opt for a gluten-free cake mix.
- Sugar-free: Substitute sugar with a sugar-free alternative.
- Vegan: Use plant-based milks and egg substitutes.
- Dark chocolate: Choose a dark chocolate cake mix for antioxidants.
- Less sweet: Reduce the amount of condensed milk slightly.
Common Mistakes to Avoid
Mistake 1: Skipping the Water Bath
The water bath is crucial for even baking. Without it, the flan may not set properly. Always use a deep enough pan to hold the mold securely.
Mistake 2: Overmixing the Flan
Overmixing can incorporate air bubbles, leading to cracks. Blend just until smooth for a velvety texture.
Mistake 3: Rushing the Cooling Process
Patience pays off! Let the cake cool completely before chilling. Otherwise, condensation can ruin the layers.
Mistake 4: Using Cold Eggs
Cold eggs can cause the batter to separate. Bring them to room temperature for best results.
