This bungeoppang recipe with rice flour delivers the perfect balance of crispy, golden shells and sweet, gooey fillings—just like the beloved Korean street food.

What makes this recipe special is its versatility: you can adapt it for dietary preferences, from vegan-friendly fillings to classic sweetened options.

The beauty of bungeoppang is in its simplicity—just rice flour, water, and a touch of oil create the crispy shells, while minimal ingredients (like honey or condensed milk) enhance the filling.

Ingredients for bungeoppang recipe rice flour

Rice flour, red bean paste, and a touch of oil create the perfect crispy shells for this Korean classic.

The rice flour is the star here—look for fine grind at Asian markets or the international aisle of larger grocery stores. Bob's Red Mill or King Arthur brands work well if you can't find specialty rice flour. The red bean paste should be smooth, not chunky—Korean markets often carry the best quality, but Trader Joe's has a decent jarred version. Toast your sesame seeds in a dry pan for 30 seconds until fragrant; this adds depth without overpowering. For the oil, vegetable or canola works best—avoid olive oil, which can make the shells greasy.

No red bean paste? Sweetened mashed chickpeas or brown sugar mixed with a splash of water make great substitutes. Running short on honey? Maple syrup or agave nectar work in a pinch. The cornstarch is optional but worth it—it gives those shells an extra crunch. If you're avoiding gluten, ensure your rice flour is certified gluten-free, as some brands process in shared facilities. For a vegan version, simply omit the honey and use maple syrup instead.

Store the dry rice flour mix in an airtight container for up to 2 weeks—it keeps well in a cool, dark place. The filled bungeoppang can be refrigerated for 3 days or frozen for 2 months (wrap individually in parchment). To reheat, bake at 350°F for 5-7 minutes until crispy again. The sesame seeds stay fresh longest if toasted fresh each time, but pre-toasted seeds keep for 1 month in a sealed container.

Step-by-step instructions for bungeoppang with rice flour

Master the art of creating crispy, golden shells filled with sweet red bean paste using this precise method.

In a mixing bowl, combine the 1.5 cups rice flour, 1.5 cups water, 2 tbsp vegetable oil, 1 tbsp cornstarch, 0.25 tsp salt, and 0.25 tsp baking powder. Use a whisk or fork to mix until smooth and free of lumps. The batter should be thin but cohesive, like pancake batter. If it's too thick, add a splash of water; if too thin, stir in a bit more rice flour.

Next, add the 1 tbsp vegetable shortening and 1 tsp sesame oil to the batter. Mix until fully incorporated—this step is crucial for achieving that signature golden color and crispy texture. Let the batter rest for 10 minutes at room temperature. This resting period allows the flour to fully hydrate and the gluten to relax, resulting in a smoother batter that will create perfectly crisp shells.

Line a baking sheet with parchment paper and lightly grease it with a small amount of vegetable oil. Using a spoon or small ice cream scoop, drop 1.5 cups red bean paste onto the prepared sheet, spacing the dollops about 2 inches apart. Flatten each dollop slightly with the back of the spoon to create a smooth, even base.

Carefully pour the rested batter over the red bean paste, allowing it to flow naturally and cover the paste completely. The batter should be about ¼ inch thick over each dollop. Use a small offset spatula to gently spread the batter evenly and create a smooth surface. Avoid pressing too hard, as this can cause the shells to crack during baking.

Preheat your oven to 375°F and place a wire rack on the middle shelf. Once the oven is fully preheated, carefully transfer the baking sheet to the oven. Bake for 12-15 minutes until the bungeoppang develop a deep golden brown color and the shells appear crisp and dry to the touch. You'll notice the edges start to pull away from the parchment paper—this is your signal that they're nearly done.

Remove the bungeoppang from the oven and let them cool on the baking sheet for 5 minutes. This brief cooling period helps set the shells and makes them easier to handle without breaking. While they're still warm, sprinkle the 1 tbsp sesame seeds evenly over the tops. For extra sweetness, drizzle the 2 tbsp honey mixed with 0.25 cup brown sugar over each bungeoppang. Let them cool completely before serving to allow the flavors to meld.

Serve the bungeoppang warm, straight from the oven if possible. The contrast between the crispy, golden shell and the creamy, sweet red bean paste is what makes this treat so special. If you've made them ahead, reheat in the oven at 350°F for 5-7 minutes to restore their crispiness. The sesame seeds will add a delightful nutty aroma and crunch with every bite.

For the best experience, enjoy these immediately after baking while the shells are at their crispest. The combination of the golden, crackly exterior and the smooth, sweet filling creates a perfect balance of textures and flavors that's hard to resist. Store any leftovers in an airtight container at room temperature for up to 3 days, but be warned—they won't stay crisp for long!

Storing and reheating this dish

Room Temperature Storage

Freshly made bungeoppang stay best at room temperature for 2-3 days if stored properly. Place them in a single layer on a wire rack inside an airtight container with a paper towel to absorb any excess moisture.

This prevents soggy shells while keeping the filling moist. I like using glass containers with silicone lids because they allow for better airflow than plastic. 🌟

Refrigerator Refresh

If you need to store them longer, refrigeration works for up to 5 days. The shells will lose some crispiness but regain it beautifully when reheated. Place them in a single layer on a baking sheet before storing to prevent sticking.

When ready to eat, simply reheat at 350°F for 5 minutes until golden again. The filling stays perfectly creamy through this process.

Freezer Magic

For maximum shelf life, freeze your bungeoppang for up to 2 months. Wrap each one individually in parchment paper, then place them in a freezer bag with all the air squeezed out.

When ready to enjoy, thaw at room temperature for 30 minutes before reheating at 350°F for 7-8 minutes. The shells will crisp up beautifully, though they might need an extra minute or two compared to fresh ones.

Reheating Secrets

Oven reheating is your best friend for restoring crispiness. Place bungeoppang on a baking sheet lined with parchment paper and heat at 350°F for 5-7 minutes until golden brown. For a quick fix, you can also use the air fryer at 350°F for 3-4 minutes.

I avoid microwaving because it makes the shells rubbery. Always check the internal temperature—it should reach 165°F for safety.

Filling Preservation

The red bean paste filling stays fresh for 2 weeks in the refrigerator if stored in an airtight container. For extra freshness, I sometimes make a double batch of filling and freeze half of it in ice cube trays.

Once frozen solid, transfer the cubes to a freezer bag. This way, you always have perfectly portioned filling ready for your next batch of bungeoppang. 💫
