FAQ ❓

Is custard tart a good source of protein?

In its classic version, it contains a moderate amount of protein from the eggs and milk. Adding whey, however, can significantly increase its protein content, to as much as 18 g per serving, making it an ideal snack after exercise or as part of a balanced diet.

Is high-protein custard tart healthy?

Yes, if it is made with quality ingredients such as skimmed milk, vanilla whey, a small amount of sugar, and cornstarch. It is low in fat, filling, and helps maintain muscle mass while remaining low in calories.

Is high-protein custard tart good for a diet?

Absolutely. This tart is a delicious alternative to traditional desserts and can easily fit into a low-calorie or high-protein diet. It lets you enjoy a treat without exceeding your nutritional goals.

Is high-protein custard tart high in calories?

No, this recipe is relatively light. Each serving contains around 90 kcal, much less than a classic custard tart. It is therefore a dessert that can fit into a weight-loss plan.

Which whey should I use for custard tart?

Vanilla or unflavoured whey is ideal for this recipe. It mixes well when heated, does not taste artificial, and gives the tart the desired creamy texture. You can use whey isolate to limit the carbohydrate and fat content.

Can I make a protein flan without whey?

Yes, you can replace the whey with plant protein (pea, rice, etc.) or almond powder, but the texture and nutritional content will be different. The result will often be a little denser and less smooth.

Does protein flan contain sugar?

This version contains just one tablespoon of brown sugar, which is a very modest amount. For a sugar-free version, you can use a natural sweetener such as erythritol or stevia.

How should I store homemade protein flan?

Once cooled, it will keep in the refrigerator in an airtight container for up to 4 days. You can also cut it into portions and freeze them, so you always have a protein-rich snack on hand.

Can I freeze whey flan?

Yes, it can be frozen. Cut it into portions, wrap them individually, and store them in the freezer. To serve, let a portion thaw in the refrigerator or heat it in the microwave for a few seconds.

Why use cornstarch in flan?

Cornstarch replaces flour here to give the flan a light texture without making it heavy. It also thickens the flan without the need for cream or butter, making the mixture considerably lighter.

Can I make protein flan without eggs?

Yes, you can replace the eggs with alternatives such as applesauce, plant-based yogurt, or a mixture of flaxseeds and water. The result will be a little less firm, but still delicious.

Corn Starch adds nothing to the flavor, and gives a really offputting texture. It just doesn't taste good.
