Easy Custard Toast Viral Baked Egg Breakfast is the kind of recipe you make when you want something warm, sweet, and filling, but you do not want to dirty a bunch of bowls. If you have ever stood in the kitchen staring into the fridge thinking, I just need breakfast to be easy today, this one is for you. It is basically toast with a creamy yogurt and egg custard baked right into the middle. The outside gets crisp, the center turns soft and pudding like, and it feels way fancier than it actually is. I started making it after seeing it everywhere, and now it is in my regular rotation. 
What is Custard Toast?
Custard toast is bread with a little well pressed into the center, filled with a quick custard, then baked until it sets. The viral version usually uses yogurt plus egg, so it tastes lightly tangy, like cheesecake vibes without the work. If you have tried French toast, think of this as its easier cousin, because you are not soaking anything or flipping slices on a pan.
The reason it works is simple: the egg bakes up firm, and the yogurt makes it creamy. You end up with crispy edges and a soft custard center all in one bite. It is sweet enough for a treat, but still has protein so you are not hungry again in 20 minutes.
Also, if you are on a little egg kick lately, you might like other quick viral breakfasts too. I have been making these easy pesto eggs TikTok viral breakfast on busy mornings when I want something savory.
How do you make Yogurt Custard Toast?
This is the part I love, because it is mostly stir, fill, bake, eat. The only thing that can feel tricky the first time is pressing a well into the bread. Just go slow and do not smash all the way through.
Ingredients and what you will need
- 2 slices of thick bread like brioche, challah, Texas toast, or thick sandwich bread
- 1 large egg
- 3 to 4 tablespoons plain Greek yogurt or regular plain yogurt
- 1 to 2 tablespoons maple syrup, honey, or sugar (adjust to taste)
- 1 teaspoon vanilla (optional but so good)
- Pinch of salt
- Optional: lemon zest or cinnamon
Tip on bread: Thick bread is your best friend here. Thin slices can tear or get soggy. If your bread is a little stale, even better. It holds the custard like a champ.
Simple directions
- Preheat your oven to 350 F. Line a sheet pan with parchment if you want easy cleanup.
- Use the back of a spoon to gently press down the center of each slice, leaving a border around the edges like a crust.
- In a small bowl, whisk the egg, yogurt, sweetener, vanilla, salt, and any extras like cinnamon.
- Spoon the custard into the wells. Do not overfill, it puffs a bit.
- Bake for about 12 to 16 minutes until the center looks set and the edges are golden.
- Let it sit for a minute, then add toppings and eat warm.

Ways to customize the custard
Once you have the basic method down, customizing is the fun part. I keep it pretty classic most days, but when I want a change, I tweak the custard itself.
Here are easy swaps that actually taste good:
Make it richer: Use full fat Greek yogurt and add an extra teaspoon of honey.
Make it lighter: Use regular plain yogurt and go easy on the sweetener.
Add warm spice: Cinnamon, nutmeg, or pumpkin spice are all great.
Add brightness: Lemon zest or a tiny splash of orange juice wakes it up.
Add cocoa: Whisk in a teaspoon of cocoa powder for a chocolate custard vibe.
If you are dairy free, you can try a thick plant based yogurt, but just know the texture may set a little softer. I would bake it a couple minutes longer and watch closely.
And if you are in a savory mood, you can still keep the same concept and pivot to other egg breakfasts. I have a salty crunchy obsession with these easy crispy feta eggs Mediterranean breakfast when I want something bold and not sweet.
Toppings to add on Custard Toast
Toppings are where custard toast turns into your breakfast personality on a plate. I usually top mine right after baking so everything melts a little and sticks.
My favorite topping ideas:
Fresh fruit: berries, sliced banana, peaches, or mango
Crunch: granola, chopped pistachios, almonds, or toasted coconut
Extra sweetness: a drizzle of honey, maple syrup, or a dusting of powdered sugar
Nut butter: peanut butter or almond butter swirled on top
Jam: a spoonful of strawberry or raspberry jam tastes like a fancy danish
If you want a fun brunch moment, do a little berry and powdered sugar situation and serve it with coffee. If you are packing breakfast to go, I would bake it, cool it, then bring toppings in a small container to add later so it stays crisp.
Speaking of packing breakfast, if you need something more filling for work or school, this easy breakfast burrito lunch box make ahead is one I keep in my back pocket.
How to tell when the yogurt toast is ready
This is the difference between dreamy custard and a runny center that spills everywhere. You want the custard to look set, not wet, but still soft.
Here is what I look for every time:
The center: It should not jiggle like liquid when you gently shake the pan. A tiny wobble is fine, but it should look mostly firm.
The edges: The bread should be golden and feel crisp to the touch.
The top: It will look slightly glossy but not raw.
If your bread is browning too fast but the center is still loose, lower the oven temp a bit next time or use a thicker bread that can handle the bake time. Every oven is a little different, so the first time is your test run.
Also, do not skip the one minute rest after baking. That little pause helps the custard finish setting, and it is much easier to eat.
Common Questions
Can I make Easy Custard Toast Viral Baked Egg Breakfast in an air fryer?
Yes. Air fry at about 330 to 350 F and start checking around 6 to 8 minutes. The edges brown faster, so keep an eye on it.
Do I have to use Greek yogurt?
Nope. Greek yogurt gives a thicker, cheesecake like center. Regular yogurt works too, it may just be a bit softer and may need an extra minute or two.
Why did my custard sink or crack?
A little sinking is normal as it cools. Cracking usually means it baked a bit too long or your oven runs hot. Pull it when it is set but still tender.
Can I prep it ahead of time?
You can mix the custard the night before and store it covered in the fridge. I would fill the bread right before baking so it does not get soggy.
Is this safe with egg in the middle?
As long as you bake until the custard is set and not runny, it is cooked. If you are unsure, bake it a couple minutes longer and use thicker bread so it does not overbrown.
