Last Updated on May 31, 2023 by Lauren Beck

As an avid lover of all things sweet, I’ve perfected making flan in plastic cups. These individual portions of creamy caramel goodness are delicious and incredibly convenient. 

Join me as I share my tried-and-true steps to create delectable flan in plastic cups that will impress your taste buds.

How to Make Flan in Plastic Cups?

Here is a concise version of the steps to make flan in plastic cups:

  1. Prepare the caramel by melting sugar and coating the bottom of each plastic cup.
  2. Whisk together eggs, condensed milk, evaporated milk, and vanilla extract to make the custard mixture.
  3. Pour the custard mixture over the caramel in each cup.
  4. Place the cups in a larger baking dish with hot water, cover with foil, and bake at 325°F (160°C) for 45-60 minutes.
  5. Let the cups cool, cover, and refrigerate for 2-3 hours.
  6. To serve, unmold the flan by inverting each cup onto a serving plate.
  7. Enjoy chilled!

Tips For Making Perfect Flan

  • Use High-Quality Ingredients: Opt for fresh eggs, high-quality milk, and pure vanilla extract to enhance the flavor and texture of your flan.
  • Strain the Mixture: To achieve a smooth and silky flan, strain the custard mixture before pouring it into the plastic cups. This helps remove any lumps or air bubbles.
  • Allow the Caramel to Cool: When making the caramel sauce, let it cool and harden slightly before pouring the custard mixture. This helps create a beautiful caramel layer on top of the flan.

Can You Make Flan In A Plastic Container?

Yes, you can make flan in plastic cups or containers. Plastic cups are a convenient and portable option for individual servings of flan. 

Just make sure the cups are heat-resistant and suitable for baking or microwaving.

Do You Cook Flan Covered Or Uncovered?

Flan is typically cooked in a water bath [1], where the custard cups are placed in a larger baking dish filled with hot water. 

Covering the flan cups with aluminum foil during cooking is best to prevent excessive browning or drying out. 

However, in the final stages of cooking, the foil can be removed to allow the caramel to darken and develop a rich color.

Do You Cover Flan In The Fridge?

After cooling and setting, cover the flan with plastic wrap or place it in an airtight container before refrigerating to maintain its freshness.

This helps prevent the absorption of any odors from other foods in the refrigerator and maintains the freshness of the flan.

How To Make Flan Without Oven?

If you don’t have access to an oven, you can still make flan using alternative methods such as stovetop cooking or microwave. Here’s a brief guide for each method:

  • Stovetop Cooking: Position the filled plastic cups in a sizeable pot or steamer basket. Add water to the pot, making sure it reaches about halfway up the sides of the cups. Cover the pot and steam the flan over medium-low heat for about 25-30 minutes or until set.
  • Microwave Method: Fill the plastic cups with the custard mixture and place them on a microwave-safe plate. Cook in the microwave on medium power in short intervals, checking the flan’s doneness after each interval. This method requires monitoring to prevent overcooking or uneven heating.


With these simple steps, you can easily make flan in plastic cups and enjoy the creamy, caramel-infused delight at your convenience. The individual portions add a touch of elegance and make serving a breeze. 

So gather your plastic cups, follow the recipe, and indulge in the velvety texture and rich flavor of homemade flan. It’s a delightful dessert that will leave you and your guests wanting more. 

Get creative with variations and toppings to make it your signature treat. Embrace the joy of making flan in plastic cups, and let your culinary skills shine!
