4 Ingredient Keto Flan Ingredients
• A delightful low-carb dessert awaits!
For the Caramel
- Allulose – This primary sweetener provides sweetness without carbs and caramelizes beautifully.
- Water – Necessary for transforming allulose into a rich caramel.
For the Custard
- Whole Milk – Adds creaminess; substitute with a low-carb milk alternative for a dairy-free option.
- Eggs + Egg Yolk – Three large eggs plus one yolk give the custard its signature velvety texture and structure.
Step‑by‑Step Instructions for 4 Ingredient Keto Flan
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This step is essential as it prepares the perfect environment for baking your 4 Ingredient Keto Flan evenly. While the oven heats, ensure you have a 7-inch round cake pan ready for the caramel.
Step 2: Make the Caramel
In a non-stick skillet, combine ½ cup of allulose with a little water over medium heat. Stir gently and let the mixture cook for about 8 to 10 minutes until it transforms into a golden caramel color. Once ready, carefully pour the caramel into your prepared cake pan and set aside to harden.
Step 3: Prepare the Custard
In a saucepan, heat 2 cups of whole milk and ⅔ cup of allulose over low heat, stirring until the sweetener dissolves completely. This process should take about 5 minutes. After the mixture is warm but not boiling, remove it from heat and let it cool slightly before incorporating unbeaten eggs and the egg yolk.
Step 4: Incorporate the Eggs
Once the milk mixture has cooled a bit, gradually whisk in 3 large eggs and the additional egg yolk. This creates a velvety custard base that will give your 4 Ingredient Keto Flan its delicious texture. Whisk until everything is fully combined and smooth.
Step 5: Strain the Mixture
To ensure your custard is silky smooth, strain the egg mixture through a fine-mesh strainer into the caramel-lined cake pan. This will catch any bits of cooked egg, resulting in a flawless flan. Allow it to settle for a moment before proceeding to the next step.
Step 6: Bake in a Water Bath
Place the flan pan inside a larger baking dish. Fill the outer dish with hot water until it reaches halfway up the sides of the flan pan. This water bath technique keeps the custard creamy while baking. Bake for 40 to 50 minutes, watching for the edges to set while the center should jiggle fluidly.
Step 7: Cool and Refrigerate
After baking, remove the flan from the oven and allow it to cool at room temperature for about 30 minutes. Then, cover it and transfer to the refrigerator. Chill the flan for at least 4 hours or, preferably, overnight for it to set completely, ensuring the flavors meld beautifully.
Step 8: Serve
When ready to serve your 4 Ingredient Keto Flan, gently invert it onto a plate. This will allow the luscious caramel to drizzle over the creamy custard. Slice into portions and serve chilled, ready to delight your guests with a rich, low-carb dessert experience.

Expert Tips for 4 Ingredient Keto Flan
-
Use Allulose Only: Allulose is the secret to perfect caramel in this keto dessert. Other sweeteners won’t caramelize properly, so stick with allulose for the best results.
-
Watch the Cooking Time: Avoid overcooking by checking the flan often; it should jiggle slightly in the center when done. This ensures a creamy texture rather than a rubbery finish.
-
Proper Cooling: Allow the flan to cool completely before refrigerating. This step is crucial for proper setting, ensuring your low-carb flan has the desired consistency.
-
Strain for Smoothness: Don’t skip straining the custard mixture. This simple step helps eliminate any clumps, resulting in a luxuriously smooth 4 Ingredient Keto Flan.
-
Chill Time Matters: For optimal flavor and texture, let the flan chill overnight. It allows the caramel to soak in and enhances the overall dessert experience.
4 Ingredient Keto Flan Recipe FAQs
What type of allulose should I use for this flan?
Absolutely use granular allulose, as it caramelizes beautifully and is key to achieving the perfect caramel topping. Other types of sweeteners may not perform the same way, leading to disappointing results.
How do I store leftover flan, and how long does it last?
After your family has enjoyed their fill, keep any leftover 4 Ingredient Keto Flan tightly covered in the fridge for up to 3 days. This ensures it remains fresh and maintains its exquisite creamy texture.
Can I freeze the flan for later use?
Yes! You can freeze the 4 Ingredient Keto Flan for up to 1 month. Just wrap it tightly in plastic wrap followed by aluminum foil to avoid freezer burn. When you’re ready to indulge, thaw it in the refrigerator overnight to keep it smooth and creamy.
What should I do if my flan came out rubbery?
If you find your flan is rubbery, it may have been overcooked. Be sure to check it around the 40-minute mark—it’s done when the edges are set but the center still jiggles slightly. Next time, keep an eye on the baking time to ensure a perfect custard consistency!
Is this flan safe for people with allergies?
While this 4 Ingredient Keto Flan contains common allergens such as eggs and dairy, it’s gluten-free and low-carb. If you’re accommodating specific allergies, consider replacing whole milk with a low-carb dairy-free alternative like almond or coconut milk.

The more the merrier! Feel free to whisk in a couple of teaspoons of vanilla extract for enhanced flavor. You can also experiment with dairy-free milk options if desired. Just ensure any substitutes maintain a low-carb profile for the best results.
