Hi, I’m Lin from Woks of Love. If you bake as much as I do, you often find yourself staring at half a loaf of leftover white bread that’s starting to lose its softness. Instead of letting it go to waste, one of my absolute favorite ways to revive it is by making Huang You Sha Tang Tu Si (黄油砂糖吐司)—Butter Sugar Toast.
This is a nostalgic, incredibly fast snack that transforms ordinary bread into a bakery-worthy treat. With just three ingredients and 10 minutes of your time, you get a beautiful caramelized crust on top and a fluffy, butter-soaked center. Let me show you my foolproof method for getting that perfect texture every single time.
What Is Butter Sugar Toast (Huang You Sha Tang Tu Si)?
Butter Sugar Toast is exactly what it sounds like: thick slices of white bread deeply scored, slathered with melted butter, sprinkled with granulated sugar, and baked until crispy. It is a beloved staple in many Asian bakeries and cafes, known for its contrasting textures—the crunch of the baked sugar and the rich, tender crumb beneath.
If you love the concept of transforming simple bread in an appliance like an air fryer or oven, you might also enjoy my Cheesy Air Fryer Shrimp Toast for a highly savory, seafood-forward alternative that shares a similarly satisfying crunch!
Ingredients
- 4 slices thick-cut white bread (Shokupan / Milk Bread is highly recommended)
- 1.4 tbsp (20g) Unsalted Butter, completely melted
- 1.5 tbsp (20g) Granulated Sugar
Ingredient Notes
The type of bread you use drastically impacts the final result. Asian-style milk bread (Shokupan) is ideal because of its tight crumb and slight sweetness. If you cannot find milk bread at your local Asian market, use a sturdy, thick-cut white bread. Avoid pre-sliced sandwich bread that is too thin, as it will dry out entirely in the oven rather than retaining a soft interior.
Equipment Needed
- Oven or Toaster Oven (capable of reaching 340°F / 170°C)
- Baking Sheet
- Pastry Brush (for even butter distribution)
Prep & Mise en Place
The most important prep step is scoring the bread. Place the slices on a board and use a serrated knife to cut a crosshatch (checkerboard) pattern into the top of the bread.
💡 Why score the bread? Scoring increases the surface area of the toast. This allows the melted butter to seep deeply into the crumb rather than just pooling on top, ensuring rich flavor throughout and allowing the heat to penetrate for an extra crispy texture.
Cooking Process
- Step 1: Preheat the Oven. Set your oven to 340°F (170°C). Meanwhile, melt your butter. Using a double boiler method (隔水融化) is gentle and traditional, but a 15-second blast in the microwave works perfectly for the home cook.
- Step 2: Score the Bread. Cut the crosshatch pattern into your 4 slices of bread. Crucial: Only cut about halfway down into the slice. Do not cut all the way through, or your toast will fall apart when you move it.
- Step 3: Butter and Sugar. Generously brush the melted butter over the tops of the toast, ensuring it gets into the crevices you just cut. Evenly sprinkle the granulated sugar over the buttered surface.
- Step 4: Bake. Place the toast on the middle-lower rack of your preheated oven for 8–9 minutes. If you prefer a darker, deeper color and an extra-shatteringly crisp top, move the baking sheet to the top rack for the final 1–2 minutes of baking.
- Step 5: Cool to Crisp. Remove the toast from the oven. It will still feel slightly soft. Let it sit on a wire cooling rack for 2–3 minutes. As the sugar cools, it solidifies into a delightful, crispy crust.
Why This Recipe Works
- Structural Contrast: The thick-cut bread provides a strong foundation, keeping the bottom soft while the top gets crunchy.
- Deep Penetration: The crosshatch scoring ensures every bite contains buttery richness.
- Temperature Control: Baking at 340°F (170°C) gently toasts the bread without burning the delicate sugar granules too quickly.
Common Mistakes When Making Butter Sugar Toast
Mistake: The toast falls apart.
Reason: You cut all the way through the bread when scoring.
Solution: Only cut halfway into the thickness of the slice. Use a gentle sawing motion with a serrated knife.
Mistake: The top isn’t crispy.
Reason: The toast was eaten immediately out of the oven.
Solution: The melted sugar needs a few minutes to cool and solidify into a hard, candy-like crust. Always rest the toast on a wire rack for 2-3 minutes before serving.
Frequently Asked Questions
Can I use brown sugar instead of white sugar?
Yes, brown sugar will add a lovely molasses flavor, though it may result in a slightly chewier crust rather than a snappy, crispy one.
Can I make this in an air fryer?
Absolutely! Set your air fryer to 320°F (160°C) and air fry for 4-6 minutes, keeping a close eye on it to prevent burning.
Can I make it ahead of time?
Butter Sugar Toast is best enjoyed freshly made. If left out too long, the sugar can attract moisture from the air and become sticky or soft.
Is this an authentic Chinese dish?
While not a traditional ancient Chinese recipe, it is an extremely authentic and popular item found in modern Chinese bakeries, cafes, and home kitchens for breakfast.
How to Serve
Serve this toast immediately while it’s still warm but the sugar crust has set. It pairs beautifully with a hot cup of black tea, coffee, or milk. If you want to create a full Asian-style breakfast spread, serve this alongside a comforting bowl of Red Bean and Black Rice Porridge or balance the sweetness with some Savory Chinese Breakfast Pancakes and Chinese Tea Eggs. For a heartier side, try an Easy Chinese Mushroom Soup or pair it with some Pork Floss Buns for contrasting flavors.

Storage & Reheat
- Storage: Store any leftovers in an airtight container at room temperature for up to 1 day. Do not refrigerate, as it will dry out the bread.
- Reheat: To restore crispness, place in a 300°F (150°C) oven or toaster oven for 2-3 minutes. Do not microwave.

About the Author & Recipe Development
I’m Lin, the recipe developer behind Woks of Love. I grew up with the comforting aromas of Chinese home cooking and bakery treats. For this specific recipe, I tested various temperatures and scoring depths to find the exact ratio that guarantees a perfectly golden, sugary crust without drying out the interior of the bread. My goal is to bring reliable, foolproof Asian recipes into your daily kitchen routine.

The distinct caramelization and golden color achieved in this recipe are driven by the Maillard reaction. This chemical reaction between amino acids and reducing sugars requires temperatures above 285°F (140°C), which is why baking at 340°F (170°C) is essential for that perfect bakery-style finish.
Crispy Butter Sugar Toast (Huang You Sha Tang Tu Si)
Equipment
- Oven or Toaster Oven
- Pastry Brush
Ingredients
Toast
- 4 slices thick-cut white bread (shokupan or milk bread) crusts left on
- 1.4 tbsp unsalted butter melted
- 1.5 tbsp granulated sugar adjust to taste
Instructions
- Preheat your oven to 340°F (170°C). Melt the butter in a double boiler or briefly in the microwave until completely liquid.
- Place the 4 slices of bread on a cutting board. Using a serrated knife, score the top of each slice in a crosshatch (checkerboard) pattern. Crucial: Only cut halfway through the bread; do not cut all the way to the bottom.
- Brush the melted butter evenly over the surface of the bread, making sure it seeps into the crosshatch cuts. Sprinkle the granulated sugar evenly over the buttered surface.
- Place the toast on a baking sheet on the middle-lower rack of the preheated oven. Bake for 8-9 minutes until the edges are golden. If you prefer a darker, more caramelized top, move the pan to the top rack for the final 1-2 minutes.
- Remove from the oven and let the toast rest on a wire rack for 2-3 minutes. This resting period allows the sugar to harden into a crispy crust.
