Bean Jam Buns Recipe: Fluffy Rolls Stuffed With Sweet Bean Filling

This bean jam bun recipe turns a simple morning into a celebration of texture and flavor—soft, pillowy dough cradling sweet, jammy bean filling in every bite.

This recipe bridges tradition and ease, delivering restaurant-quality baozi-style buns with a foolproof method for shaping and cooking that yields perfectly steamed (or baked) results every time. The secret lies in balancing yeast activation and dough handling to maintain that signature fluffy interior while the filling stays gooey and intact.

What sets these buns apart is the harmony between the dough and filling—light, airy rolls that don’t collapse under the weight of sweet red bean paste or homemade jam.

The dough requires just 30 minutes of active prep (plus rising time) and uses simple ingredients like all-purpose flour, yeast, and sugar, while the filling can be store-bought or homemade for customization.

For an extra touch, pan-frying after steaming adds a golden, crispy exterior that contrasts beautifully with the soft interior.

The outcome is a plate of buns that look as impressive as they taste—golden-brown tops, slightly puffed sides, and a filling that stays cohesive yet melts slightly with each bite. These buns are perfect for breakfast, brunch, or even dessert, and they reheat beautifully, making them ideal for meal prep.

Whether you’re serving a crowd or treating yourself, this recipe delivers professional results with minimal fuss.

For added versatility, experiment with fillings like black sesame paste or lotus seed paste, or adjust the dough’s sweetness to complement your preferred jam. The key is patience during shaping and steaming—don’t rush the process, and you’ll achieve buns that are light, tender, and full of flavor. Let’s get started!

Ingredients for bean jam bun

Simple pantry staples transform into restaurant-style buns with fluffy dough and sweet bean filling.

The flour is the foundation—King Arthur or Gold Medal brands yield the best texture for baozi-style buns. Active dry yeast should be fresh; test by dropping a pinch in warm water—it should foam within 5 minutes. For the bean paste, Trader Joe’s or Asian markets offer high-quality red bean paste, but homemade is ideal if you prefer less sugar. The butter should be cold and cubed to prevent overworking the dough. If your kitchen is warm, chill the dough between kneading sessions to maintain elasticity.

No red bean paste? Sweetened black sesame paste or lotus seed paste works beautifully for variation. Substitute vegetable oil with neutral-flavored coconut oil if preferred. For a gluten-free option, swap flour for a 1:1 baking blend, though texture may differ. The sesame seeds can be omitted or replaced with crushed peanuts or white sesame seeds for a different crunch. If your dough feels too sticky, add 1 tbsp more flour incrementally. For extra richness, replace 2 tbsp of water with whole milk in the dough recipe.

Store unused bean paste in an airtight container in the fridge for up to 3 months. Dough can be refrigerated for 24 hours or frozen for 1 month—thaw overnight in the fridge before shaping. Steamed buns reheat best in a 350°F oven for 10 minutes to restore crispness. For meal prep, freeze shaped buns on a tray before transferring to a bag—steam directly from frozen, adding 5 extra minutes. Leftover dough can be used for dumplings or flatbreads within 3 days.

Step-by-step instructions for bean jam buns

Here's how to create tender, fluffy rolls with a sweet red bean paste center—every bite delivers perfect texture and flavor.

In a small bowl, combine the 0.25 cup granulated sugar and 0.75 cup warm water (about 110°F). Sprinkle the 0.25 oz active dry yeast on top and let sit for 5-10 minutes until frothy. This activation step ensures your dough rises properly—you'll see bubbles forming on the surface and a yeasty aroma.

In a large bowl, whisk together the 4 cups all-purpose flour and 0.5 tsp salt. Make a well in the center and pour in the yeast mixture along with the 0.5 cup cold, cubed unsalted butter. Mix with a wooden spoon until the dough begins to come together, then turn it out onto a lightly cornstarch-dusted surface. Knead for 8-10 minutes until smooth and elastic, adding a splash of water if too dry. The dough should be soft but not sticky.

Divide the dough into 12 equal pieces (about 2 ounces each) and roll each into a 12-inch log. Gently flatten one end of each log with your palm to create a pocket. Spoon 1 tablespoon of red bean paste into the center of each flattened end, then seal the dough around the filling, pinching the edges to prevent leaks. The filling should be completely encased but not squeezed—this preserves the fluffy texture.

Place the filled buns on a parchment-lined baking sheet, spacing them about 2 inches apart. Cover with a clean kitchen towel and let rise in a warm place for 1 hour or until doubled in size. You'll notice the dough puffs up and the seams soften slightly—this indicates proper fermentation. If using sesame seeds, sprinkle them lightly over the tops now for extra flavor and texture.

Preheat your oven to 375°F. Brush the tops of the buns with 1 tablespoon vegetable oil for a glossy finish. Bake for 18-22 minutes until the buns are deep golden brown and sound hollow when tapped on the bottom. The aroma should be sweet and buttery—this is your signal they're done baking. If the tops brown too quickly, tent with foil after 10 minutes to prevent over-browning while the centers finish cooking.

Remove from the oven and let cool on a wire rack for 5 minutes before serving. The buns should be soft inside with a slightly crisp exterior, and the red bean paste should be warm and gooey. For best results, serve warm with a dusting of powdered sugar or a drizzle of honey. Store leftovers in an airtight container at room temperature for up to 2 days or freeze for longer storage.

Essential equipment for this recipe

Steamer Essentials

For authentic baozi-style buns, a bamboo steamer is my go-to tool—it distributes heat evenly and creates that signature tender crust. Look for a 14-inch round steamer with a tight-fitting lid and sturdy handles.

The T-fal bamboo steamer is my favorite because it holds 12 buns perfectly and heats up quickly on the stovetop. If you don’t have one, a large metal colander with legs works in a pinch, but avoid nonstick pans—they can trap too much moisture and make the buns soggy. 🌿

Dough Tools

A digital kitchen scale (like the OXO Good Grips) is a game-changer for dividing dough evenly—each bun should weigh 2 ounces for consistency. For shaping, use a dough scraper (I recommend Kitchy) to flatten and pinch seams without sticking.

A rolling pin with a smooth surface (like Nordic Ware) helps create even logs, but avoid overworking the dough—it should stay soft and pliable. A pastry brush (such as OXO Good Grips) is perfect for brushing oil on the tops before baking.

Filling Prep

Store-bought red bean paste is convenient, but for homemade, a high-speed blender (like the Ninja) makes quick work of pureeing soaked beans. A small offset spatula helps spread the paste evenly into the dough pockets without tearing.

For extra precision, use a piping bag with a small round tip to fill buns neatly. If your paste is too thick, add 1 tsp water to loosen it—this ensures a smooth, cohesive filling that doesn’t leak during cooking. 🍜

Optional Crispy Upgrade

For pan-fried buns, a nonstick skillet (like GreenPan) is essential—it prevents sticking while creating a golden crust. Heat ½ inch of oil (peanut or vegetable) to 350°F and fry buns for 2-3 minutes per side until crispy.
