Butter-Based Egg Yolk Pastry (Danhuangsu) Recipe: A Creamy Twist on a Classic Chinese Snack

Okay, let’s be real—traditional egg yolk pastry (danhuangsu) is amazing, but who wants to deal with rendering lard at home? Raise your hand if you’ve ever stared at a pork fat block at the grocery store and thought, “Is this worth it?” 🙋♀️ Yeah, me too. That’s why I decided to experiment with a butter-based version, and holy cow—game changer. The buttery, milky aroma that fills your kitchen? Unbeatable. The flaky layers? Even better than the lard version (don’t @ me, lard lovers). Let’s dive into this easy, no-lard-required recipe that’ll make you a pastry hero.

Why Butter Instead of Lard? Let’s Spill the Tea

First off, convenience. Rendering lard takes time—melting, skimming, straining… who has that kind of patience on a Tuesday night? Butter is just… there. Soften it, toss it in, done. No mess, no weird smells, no waiting around.

Then there’s the flavor. Lard gives a rich, savory depth, but butter? It adds a subtle, sweet creaminess that pairs perfectly with the sweet red bean and salty egg yolk. Every bite tastes like a fancy bakery treat, not just a homemade snack. Plus, the butter helps the pastry stay flakier longer (though let’s be honest, these won’t last long enough to go stale).

What You’ll Need: Ingredients Breakdown

Let’s keep this simple. No fancy ingredients here—just stuff you can grab at your local grocery store (or Amazon, if you’re like me and procrastinate). We’re making 7 pastries, so adjust if you want more!

For the Red Bean & Egg Yolk Filling

• 1 cup store-bought or homemade red bean paste (I use store-bought—no shame!)
• 7 salted egg yolks (I buy pre-cooked ones—saves time!)

For the Oil Skin (Shu Pi)

• 110g all-purpose flour (plain flour)
• 40g unsalted butter, softened to room temperature
• 18g powdered sugar (icing sugar)
• 40ml cold water

For the Pastry Crust (You Su)

• 100g cake flour (low-gluten flour)
• 50g unsalted butter, softened to room temperature

For Topping

• 1 egg yolk (for brushing)
• 1 tbsp water (mixed with egg yolk)
• Black sesame seeds (optional, but adds crunch)

Step-by-Step: Let’s Make This Happen

Before we start, pro tip: Keep your dough cold! Warm butter = messy layers. If your kitchen is hot (looking at you, summer), pop dough in the fridge between steps. Trust me.

Step 1: Prep the Filling (The “Heart” of the Pastry)

First, let’s get the filling ready so it’s waiting for the dough. Divide the red bean paste into 7 equal balls—about 20-25g each. Flatten each ball into a small disc, then place a salted egg yolk in the center. Wrap the red bean paste around the yolk, pinching the edges to seal. Roll into a smooth ball. Cover with plastic wrap and set aside—we’ll come back to these later.

Step 2: Make the Oil Skin (The “Outside” Layer)

Grab a bowl (or your stand mixer, if you’re feeling fancy) and mix the all-purpose flour, powdered sugar, and softened butter. Use a fork or your hands to rub the butter into the flour until it looks like coarse crumbs. Then add the cold water, one tablespoon at a time, and mix until a smooth dough forms. If it’s too dry, add a tiny bit more water; if it’s too sticky, add a pinch of flour.

Knead the dough for 15-20 minutes until it’s smooth and elastic. How do you know it’s ready? Do the “windowpane test”: take a small piece of dough, stretch it thin. If you can see light through it without it tearing, you’re golden! Cover the dough with plastic wrap and let it rest for 1 hour. This lets the gluten relax so it’s easier to roll later.

Step 3: Make the Pastry Crust (The “Flaky” Layer)

Now for the fun part—the pastry crust that makes the layers! In a separate bowl, mix the cake flour and softened butter. You don’t need to knead this much—just mix until it forms a smooth, crumbly dough (it should hold together when squeezed). Cover with plastic wrap and let it rest for 1 hour. If it’s hot outside, pop it in the fridge for 30 minutes first—cold butter = flakier layers!

Step 4: Divide & Conquer (Literally)

After resting, divide the oil skin into 7 equal balls (about 25g each) and the pastry crust into 7 equal balls (about 20g each). Cover both with plastic wrap—we don’t want them drying out!

Step 5: Wrap the Pastry Crust in the Oil Skin (The “Layer” Step)

Take one oil skin ball and flatten it into a small disc (about 3 inches wide). Place a pastry crust ball in the center. Fold the edges of the oil skin up around the pastry crust, pinching the top to seal. Roll it into a smooth ball. Do this for all 7 pairs. Cover with plastic wrap and pop them in the fridge for 20 minutes. Cold dough = easier to roll!

Step 6: Roll & Roll (The “Flaky Layer” Magic)

Take one chilled dough ball and roll it into an oval (about 6 inches long and 2 inches wide). Be gentle—you don’t want to tear the layers! Roll it from the top to the bottom, like a burrito. Press the seam down to seal. Do this for all 7, then cover with plastic wrap and pop them back in the fridge for 20 minutes. Repeat this step once more: roll into an oval, roll up, chill for 20 minutes. Yes, this is tedious, but trust me—those layers are worth it.

Step 7: Shape & Fill (The “Pastry” Step)

Take one chilled dough burrito and press the center with your thumb. Fold the two ends towards the center, then press flat. Roll it into a circle (about 4 inches wide), making sure the center is thicker than the edges (this prevents the filling from bursting out). Place a red bean-egg yolk ball in the center. Use the “tiger mouth” method (pinch the edges with your thumb and index finger) to wrap the dough around the filling, pinching the top to seal. Roll into a smooth ball. Do this for all 7.

Step 8: Bake (The “Smell Good” Step)

Preheat your oven to 170°C (340°F) (convection oven: 150°C/300°F). Brush the top of each pastry with the egg yolk-water mixture, then sprinkle with black sesame seeds (optional, but so pretty!). Bake for 20 minutes at 150°C (300°F), then turn up the heat to 160°C (320°F) and bake for another 10 minutes. Keep an eye on them—you want a golden brown top, not burnt!

Pro Tips to Avoid Disaster

Let’s be real—pastry can be tricky. Here are my top tips to make sure your butter-based egg yolk pastries turn out perfect:

• Keep it cold: Warm butter = melted butter = no layers. Pop dough in the fridge between every step. If your kitchen is 80°F+, work in batches and chill longer.
• Don’t overwork the dough: Over-kneading = tough pastry. Knead just until smooth, then stop.
• Use pre-cooked egg yolks: Raw yolks can be runny, and pre-cooked ones are already salty (perfect for the sweet-savory balance).
• Adjust baking time: Ovens vary! If your pastries are still pale after 30 minutes, bake for 5 more minutes. If they’re browning too fast, cover with foil.

My Honest Review: Did This Work?

Okay, let’s cut to the chase—how did these turn out? AMAZING. The first bite? Crunchy, flaky, buttery, with a burst of sweet red bean and salty egg yolk. I ate three in a row (no shame). My roommate walked in, smelled them, and demanded one. Now she’s begging me to make more. The butter really does make a difference—no weird lard aftertaste, just pure creamy goodness.

The only “mistake” I made? I forgot to chill the dough between the first roll-up step, and it tore a little. But it still tasted great! So don’t stress if yours aren’t perfect—pastry is forgiving (mostly).

Final Thoughts: Would I Make This Again?

100% yes. In fact, I’m making a double batch this weekend for my family. The butter-based version is easier, tastier, and less messy than the lard version. Plus, the smell when they’re baking? It fills the whole house—my neighbors probably think I’m a professional baker (shhh, don’t tell them it’s just this recipe).

If you’re a beginner pastry maker, don’t be scared! This recipe is forgiving, and the steps are easy to follow. Just remember: cold dough, patience, and lots of butter. You’ve got this!
