Did you know that the milk carton you usually throw away can be transformed into the perfect tool for preparing a delicious, 100% homemade recipe? 😱
Yes, you read that right.
Today I’m revealing a trick that’s taking social media by storm and will save you money, help you recycle, and eat healthier without leaving home.
After trying this, you’ll never buy certain products at the market again .
💡 The secret is in the milk carton
The milk carton (also known as a Tetra Pak) is one of the most useful items in the kitchen that almost no one takes advantage of.
Made of cardboard, aluminum, and a protective plastic layer , it’s a sturdy, clean container, perfect for baking, freezing, or storing food .
But what few people know is that it can also be used to prepare complete recipes — such as desserts, breads or flans — without the need for expensive molds or metal trays.
🍮 The homemade recipe that will make you forget about the supermarket
Today you will learn how to prepare a flan or milk cake with eggs , using nothing more than the ingredients you have at home and the empty milk carton as a reusable mold .
The result: a smooth, creamy, economical dessert that doesn’t require dirtying any molds. 🤩
🧂 Ingredients:
- 3 whole eggs 🥚
- 500 ml of milk (can be whole or semi-skimmed) 🥛
- 4 tablespoons of sugar (adjust to your taste) 🍬
- 1 teaspoon of vanilla essence (optional) 🌼
- 1 empty and clean milk carton (1 liter)
👩🍳 Step-by-step preparation
🧼 1. Prepare the box
Carefully cut off the top of the milk carton.
Wash the inside thoroughly with warm water and let it dry.
Make sure there are no traces of milk or odors, as it will serve as a mold.
🥛 2. Mix the ingredients
In a bowl, beat the eggs with the sugar until the mixture is frothy.
Add the milk and vanilla, mixing slowly until you obtain a smooth texture.
🍮 3. Pour the mixture into the box
Place the box on a heatproof tray or dish and pour everything into the container (as shown in the image).
The box can withstand the heat of the oven or a water bath thanks to its internal structure.
♨️ 4. Cook the flan
You have two options:
- In the oven: Place the box inside a tray with hot water (bain-marie) and bake at 170°C for 45 minutes.
- In a pot or steamer: Place the box upright, close the pot and cook over medium heat for about 40 minutes.
❄️ 5. Let it cool
Once ready, let it rest at room temperature and then refrigerate it for at least 2 hours.
🔪 6. Unmold
Cut open the box with scissors or a knife and carefully remove the flan or cake.
You’ll see that it has a firm, shiny, and delicious texture.
😋 Final result
A smooth, creamy flan bursting with natural flavor.
You don’t need an electric oven or expensive metal molds.
Just the box you’d normally throw away.
And the best part: you can prepare different versions using the same technique:
🍫 Chocolate flan: add 2 tablespoons of cocoa.
🍮 Coconut flan: use coconut milk instead of regular milk.
🍊 Citrus flan: add orange or lemon zest.
