Ingredients for bean paste buttercream
Nine ingredients craft this velvety vegan frosting with restaurant-quality texture and nutty depth.
| Ingredient | Amount | Notes |
|---|---|---|
| Red Bean Paste 🌱 | 1 cup | Smooth, high-quality preferred |
| Mung Bean Paste 🌱 | 1 cup | Alternative to red bean paste |
| Coconut Oil 🥥 | ½ cup | Refined or unrefined, solid |
| Pure Maple Syrup 🍁 | ¼ cup | Grade A or B for depth |
| Vanilla Extract 🌿 | 1 tbsp | Pure, alcohol-free preferred |
| Lemon Zest 🍋 | 1 tsp | Freshly grated for brightness |
| Pure Vanilla Bean Paste 🌿 | ½ tsp | For intensified vanilla flavor |
| Sea Salt 🧂 | ¼ tsp | Fine grain for balance |
| Cold Water 💧 | 1 tbsp | For adjusting consistency |
| Powdered Sugar 🍚 | ½ cup | Optional, for extra sweetness |
The bean paste is the heart of this frosting—high-quality red or mung bean paste makes all the difference. Look for brands like Koyo or Miyoko's, available at specialty grocery stores or online. The paste should be smooth with no graininess, ensuring a silky finish. Coconut oil provides the rich, creamy base, so opt for refined or unrefined varieties that stay solid at room temperature. Maple syrup adds natural sweetness and depth, while Grade A or B ensures a robust flavor profile. For vanilla, pure extract or bean paste elevates the frosting beyond basic sweetness.
No red bean paste? Mung bean paste works beautifully for a lighter flavor. Substitute maple syrup with agave nectar or date syrup at the same quantity, though maple offers a more complex profile. If coconut oil isn’t available, avocado oil or refined olive oil can replace it, though texture may vary slightly. For extra brightness, orange zest can swap lemon zest, though lemon’s acidity balances the richness best. Powdered sugar is optional but helpful if you prefer a sweeter frosting—start with half the amount and adjust to taste.
This frosting stores beautifully in an airtight container in the fridge for up to 1 week, though it firms up nicely after 2-3 hours of chilling before piping. For longer storage, freeze portions in small containers for up to 3 months, thawing at room temperature before use. To achieve the perfect consistency, begin with the coconut oil and bean paste at room temperature, then adjust with cold water as needed. The frosting thickens as it chills, so don’t overmix—just blend until smooth and creamy.
Why You'll Love This Recipe
- Here’s what sold me: I can make a huge batch for under $10 using store-brand bean pastes and bulk coconut oil, and it lasts in the fridge for weeks. No weird aftertaste or graininess—just pure, creamy goodness that tastes like you spent hours making it. Plus, the maple syrup adds just enough depth to make it feel special without breaking the bank. My wallet and taste buds agree.
- No-Fuss Whip: I swear by this recipe because it’s basically three ingredients plus a hand mixer—no tempering, no melting drama, just fold until fluffy. The red and mung bean pastes do all the heavy lifting; you just blend in the coconut oil until it’s silky, then sweeten with maple syrup. Honestly, I’ve made this while waiting for dinner to cook, and it still comes out perfect.
- Sweet-Savory Magic: Between us, that first bite of the creamy mung bean base with its subtle nutty depth—plus the caramel kiss from the maple syrup—is ridiculously good. The vanilla extract ties it all together without overpowering, and the coconut oil keeps it rich but never greasy. It’s the kind of flavor that makes you pause mid-bite and think, “Wait, I made this?”
- Double-Duty Filling: This buttercream isn’t just for cakes—it’s my go-to for filling mochi, slathering on toasted pandan waffles, or even dolloping over ice cream. (Yes, even on a Tuesday night.) The texture holds up for piping and spreading, so it works for both fancy desserts and lazy breakfasts. I’ve even used it to glaze roasted sweet potatoes when I’m craving something sweet-savory.
Step-by-step instructions for bean paste buttercream
This method delivers a velvety, nutty-sweet buttercream with perfect stability and professional finish.
Warm the Bean Pastes and Coconut Oil
In a medium heatproof bowl set over a pot of barely simmering water (double boiler), combine the 1 cup Red Bean Paste and 1 cup Mung Bean Paste. Stir gently to create a smooth, homogenous mixture. The goal is to warm the pastes to approximately 110°F—just enough to soften them slightly without cooking. This temperature allows the pastes to blend seamlessly with the other ingredients while preserving their natural texture.
In a separate small bowl, melt the 0.5 cup Coconut Oil using the same double boiler method. Once fully melted and smooth, remove both bowls from the heat. The coconut oil should be completely liquid but not hot to the touch—this prevents the buttercream from becoming grainy. Work quickly but deliberately to maintain control over the temperature as you proceed to the next step.
Combine Wet Ingredients for Flavor Foundation
To the warmed bean paste mixture, add the 0.25 cup Pure Maple Syrup, 1 tbsp Vanilla Extract, 1 tsp Lemon Zest, 0.5 tsp Pure Vanilla Bean Paste, and 0.25 tsp Sea Salt. Use a hand mixer or stand mixer fitted with the paddle attachment to blend these ingredients on medium speed for 2-3 minutes. This ensures the maple syrup and vanilla fully incorporate, creating a cohesive flavor base. The lemon zest will brighten the richness of the bean pastes, while the vanilla bean paste adds depth that extract alone cannot match.
Next, gradually drizzle in the melted 0.5 cup Coconut Oil while continuing to mix on medium speed. The buttercream will begin to thicken as the oil emulsifies with the bean paste mixture. If the mixture appears too thick at this stage, add 1 tbsp Cold Water one tablespoon at a time until it reaches a smooth, pourable consistency. The texture should be like thick honey—fluid enough to pipe but stable enough to hold its shape.
Incorporate Powdered Sugar for Final Texture
With the mixer running on low speed, sift in the 0.5 cup Powdered Sugar gradually to avoid creating lumps. Mix for an additional 3-4 minutes until the buttercream is completely smooth and glossy. The powdered sugar not only sweetens the mixture but also lightens the texture, giving the buttercream its signature airy quality. At this point, the consistency should be thick enough to hold peaks when piped but still spreadable with a spatula.
For a professional finish, transfer the buttercream to a clean bowl and use a rubber spatula to press it through a fine-mesh sieve. This removes any remaining lumps and ensures an ultra-smooth texture. Taste and adjust the sweetness or saltiness if needed—bean pastes can vary in intensity, so this final check guarantees balance. Cover the bowl with plastic wrap pressed directly onto the surface to prevent a skin from forming, and refrigerate for 30 minutes before using to allow flavors to meld.
Achieve Perfect Piping Consistency
Remove the buttercream from the refrigerator and re-whip it briefly on medium speed for 1-2 minutes to restore a smooth, spreadable texture. If the buttercream is too thick for piping, add 1 teaspoon Cold Water at a time until it reaches the desired consistency. It should hold its shape when piped but still be smooth enough to create decorative swirls or rosettes. For a test, pipe a small amount onto parchment paper—if it holds its form without collapsing, it’s ready to use.
The buttercream is now ready to use as a frosting, filling, or decorative element. Its rich, nutty depth pairs beautifully with cakes, cupcakes, or even as a glaze for pastries. For best results, use within 4 hours of preparation, or store in an airtight container in the refrigerator for up to 5 days. Bring to room temperature and re-whip before using to restore its silky texture.
Pro Tips For Making Bean Paste Buttercream
- Warm the Pastes First: Bean paste buttercream starts with smoothness, and cold pastes are its enemy. Microwave your red and mung bean pastes in 10-second bursts, stirring between each, until they’re just warm to the touch—like a steaming cup of tea. This melts the natural oils in the pastes, making them blend effortlessly with the coconut oil instead of fighting for texture.
- Use Room-Temp Coconut Oil: Solid coconut oil turns the mixing process into a workout. Take it out of the fridge 30 minutes before you start—just long enough to soften to the consistency of a butter pat. This way, you’re not wrestling with chunks while trying to whip it into the pastes, and the final buttercream will be silky, not grainy.
- Balance the Syrup Gradually: Maple syrup is the glue, but dump it all in at once and you’ll end up with a sticky mess. Start with half the amount, mix it in, then taste. Adjust by the teaspoon—this isn’t a science experiment, but it’s also not a guessing game. You want the sweetness to shine without overpowering the nutty depth of the bean pastes.
- Chill Before Whipping: I learned this the hard way—whipping warm buttercream too soon makes it seize up. Let the mixture sit in the fridge for 15 minutes after combining all ingredients. The pastes will firm up just enough to hold air properly, giving you that light, fluffy texture instead of a dense, sad blob. (Yes, even if you’re impatient like me.)
Wine and beer pairings for bean paste buttercream
Sweet White Wine
This bean paste buttercream pairs beautifully with dry Riesling or Sauvignon Blanc—their crisp acidity cuts through the frosting’s richness while complementing its nutty depth. I love a German Riesling with its honeyed notes, as the slight sweetness mirrors the bean paste’s natural sugar.
Serve chilled to enhance the refreshing contrast. 🍷
Earthy Red Wine
For a bolder pairing, try a Pinot Noir with its red fruit and earthy undertones. The wine’s subtle tannins won’t overpower the frosting’s smooth texture, creating harmony with desserts like matcha mochi or chocolate cakes. Opt for a Willamette Valley Pinot Noir for a lighter, fruit-forward profile. 🍇
Creamy Beer Pairings
A Belgian Witbier like Stella Artois or Hoegaarden adds effervescence that cleanses the palate between bites. The coriander and citrus notes in these beers brighten the frosting’s nutty flavors, making them ideal for lighter desserts.
For a richer option, try a Belgian Dubbel like Westmalle Trappist—its caramel and spice notes mirror the bean paste’s depth. 🍺
Herbal Tea Synergy
Skip alcohol entirely with jasmine green tea or earl grey—their floral notes elevate the frosting’s vanilla and citrus zest. Brew a strong cup and serve warm to enhance the bean paste’s nutty undertones. For a caffeine-free option, hibiscus tea adds a tart contrast that balances the sweetness beautifully. ☕
Spiritous Elevations
Infuse the frosting’s flavors further with a sake-infused drizzle—just mix 1 tbsp sake with 1 tsp powdered sugar and drizzle over mochi or cakes. Alternatively, a rum-soaked fruit compote (like passionfruit) pairs wonderfully with the frosting’s richness. Keep spirits at 15-20% of the total volume to avoid overpowering. 🥃

Frequently asked questions
Can I make this buttercream without coconut oil?
Yes! For a neutral flavor, use avocado oil or refined olive oil instead. The texture will remain creamy, though coconut oil’s slight sweetness enhances the bean paste’s nutty notes. If you prefer a dairy-free butter alternative, try vegan butter** (like Miyoko’s) at a 1:1 ratio, but reduce the powdered sugar slightly to avoid heaviness.
How do I adjust the sweetness for kids?
Start by adding 1-2 tablespoons extra powdered sugar at a time while mixing. For a healthier option, blend 1 tablespoon date syrup into the maple syrup before adding to the mixture. Always taste-test after mixing—bean pastes vary in natural sweetness, so adjustments may be needed.
Why did my buttercream turn grainy?
Graininess usually happens when ingredients aren’t fully emulsified or if the coconut oil is too hot. Always warm the bean paste and oil gently (110°F max) using a double boiler, and mix on medium speed for 3-4 minutes after adding powdered sugar. If it’s already grainy, press the mixture through a fine-mesh sieve or blend briefly with a hand mixer to smooth it out.
Can I color this buttercream for decorating?
Use gel food coloring or natural options like matcha powder (for green) or beet juice (for pink). Start with ½ teaspoon of coloring and mix well—bean paste buttercream absorbs color differently than traditional buttercream. For metallic effects, try edible luster dust or gold leaf flakes sprinkled on top after piping.
What’s the best way to fill mochi with this frosting?
Use a pastry bag with a small round tip to pipe the buttercream into mochi cups before sealing. For extra stability, chill the filled mochi for 10 minutes before serving. If the frosting leaks, ensure it’s fully chilled (30 minutes) before filling—this prevents melting. For a modern twist, pipe swirls on top of mochi cakes instead of filling them entirely.
