Best Keto Egg Yolk Custard

Finding dessert options that work with a keto diet can feel like searching for a needle in a haystack. Between dodging hidden sugars and trying to satisfy those after-dinner cravings, it’s easy to get frustrated and give up on sweet treats altogether, especially when you’re new to low-carb eating.

That’s where this keto egg yolk custard comes in: it’s rich and satisfying, follows all the keto rules, and comes together with just a handful of basic ingredients you probably already have in your kitchen.

What Kind of Cream Should I Use?

For a silky-smooth custard, you’ll want to use heavy cream or heavy whipping cream, which typically contains 36-40% milk fat. Light cream or half-and-half won’t give you the same rich results and might make your custard too thin or cause it to separate during cooking. If you’re buying cream at the store, look for options labeled as “heavy cream” or “heavy whipping cream” – they’re actually the same thing, just with different names. Just make sure to check the expiration date and give it a quick sniff test before using, as fresh cream will give you the best flavor in your custard. A good tip is to avoid ultra-pasteurized cream if possible, as regular pasteurized cream tends to produce a better texture in custards.

Options for Substitutions

Let’s talk about what you can swap in this keto-friendly custard recipe while keeping it low-carb:

• Rich cream: You can use heavy whipping cream or a mix of heavy cream and unsweetened coconut cream. Just avoid half-and-half or milk as they’ll make the custard too thin and add unwanted carbs.
• Allulose/monk fruit sweetener: Other keto-friendly options include erythritol or stevia. If using stevia, start with just a few drops and adjust to taste since it’s much sweeter. Note that erythritol might create a slight cooling effect in the final product.
• Vanilla essence: You can use vanilla bean paste (use half the amount), vanilla powder, or even try other flavors like almond extract or lemon essence for a different twist.
• Eggs: The eggs are crucial for this recipe and can’t be substituted – they’re what gives the custard its structure. Just make sure they’re room temperature before using.

Watch Out for These Mistakes While Cooking

The biggest challenge when making keto egg custard is preventing the eggs from curdling – you’ll want to slowly temper the hot cream into the egg mixture while whisking constantly, rather than combining them all at once.

Another common mistake is cooking the custard at too high a temperature – keep your heat low and steady, and never let the mixture come to a boil, as this will result in a lumpy, scrambled texture instead of that silky-smooth finish we’re after.

For the smoothest results, strain your custard through a fine-mesh sieve before cooling, which catches any tiny bits of cooked egg that might have formed during cooking, and always remember to cover the surface with plastic wrap while cooling to prevent a skin from forming on top.

When checking for doneness, the custard should coat the back of a spoon and hold a clean line when you run your finger through it – if it’s too loose, keep cooking, but if it’s starting to look grainy, remove it from heat immediately as it’s beginning to overcook.

What to Serve With Keto Egg Custard?

This silky keto custard pairs wonderfully with fresh berries like raspberries, blackberries, or strawberries – they add a nice tartness that balances out the sweet, creamy dessert. If you want to keep things strictly keto, you can add a dollop of whipped cream (just whip up some heavy cream with a touch of vanilla) on top. For some crunch, try sprinkling some toasted nuts like pecans or almonds over your serving, or add a sprinkle of cinnamon for extra warmth. This dessert is also great served chilled alongside a hot cup of coffee or tea for a cozy afternoon treat.

Storage Instructions

Keep Cool: Once your custard has cooled completely, cover it with plastic wrap pressed directly onto the surface (this prevents that pesky skin from forming). Pop it in the fridge and it’ll stay good for up to 3 days. The direct contact with the wrap is key to keeping your custard smooth and creamy!

Make Ahead: This custard is perfect for making a day before your special occasion. In fact, letting it chill overnight helps the flavors develop even more. Just remember to keep it covered well in the fridge until you’re ready to serve.

Important Note: Since this custard is made with eggs and cream, it’s best not to freeze it – the texture just won’t be the same after thawing. For the best experience, enjoy it within the first couple of days while it’s fresh and creamy.

• Calories: 1600-1800
• Protein: 25-30 g
• Fat: 150-160 g
• Carbohydrates: 20-25 g

Ingredients

• 2 cups heavy cream
• 1/4 cup allulose or monk fruit sweetener
• 3 large eggs
• 1 tbsp vanilla extract (I use Simply Organic extra-pure vanilla extract)

Step 1: Prepare the Baking Equipment

Start by preheating your oven to 180°C (350°F).

Grease four 2 or 3-inch ovenproof ramekins to prevent sticking and place them in a large baking dish.

This setup will help in creating a water bath for even baking.

Step 2: Mix the Custard Ingredients

In a large mixing bowl, whisk together all your ingredients until you achieve a smooth and combined mixture.

Ensure there are no lumps for a uniform texture.

Once mixed, evenly distribute the custard mixture amongst the four prepared ramekins.

Step 3: Prepare the Water Bath

Boil a kettle or bring 2-4 cups of water to a boil using a stovetop.

Carefully pour enough boiling water into the baking dish to submerge the ramekins in about an inch of water.

This water bath is essential for gently baking the custard to a creamy consistency.

Step 4: Bake the Custard

Carefully place the baking dish with the ramekins into the preheated oven.

Bake the custards for around 30 minutes or until they appear firm on top.

Be cautious when handling the hot water bath to avoid spills or burns.

Step 5: Serve and Store

After baking, remove the dish from the oven.

You can enjoy the custard warm straight away, or allow it to cool completely.

If you prefer a chilled dessert, once cooled, place the ramekins in the refrigerator and chill until ready to serve.
