Black Rice Dessert Recipe: Deep Purple Velvet With Coconut Cream Swirl

This black rice dessert recipe transforms humble grains into a luxurious, deep purple velvet cake with swirls of coconut cream.

The secret lies in soaking black rice overnight to soften its firm texture, then blending it into a silky batter that bakes into a moist, fudgy center with a delicate crumb.

What sets this apart is the coconut cream swirl—rich, tropical, and perfectly balanced against the earthy sweetness of the rice.

The result is a dessert that looks as stunning as it tastes, with a vibrant purple hue that makes every slice feel special. Whether you serve it chilled for a refreshing treat or warm with a drizzle of honey, this recipe delivers restaurant-quality elegance without requiring advanced techniques.

Ready in just 1 hour, it’s the perfect showstopper for dinner parties or a decadent weekend indulgence.

Ingredients for black rice dessert

Eight ingredients transform simple rice into a stunning purple velvet dessert with rich coconut swirls.

Black rice is the star here—look for it in the Asian foods aisle or order online. The uncooked version needs overnight soaking to soften its firm texture. I always buy 32-ounce bags from Trader Joe's or H-Mart for best quality. The vibrant purple hue comes from anthocyanins, so don't skip the soaking—it's what makes this dessert visually stunning. For the coconut milk, full-fat canned varieties work best—avoid the carton versions with added water.

No black rice? Substitute with purple sweet potatoes (steamed and puréed), though the texture will differ slightly. Running out of coconut cream? Whip the thick part from chilled coconut milk for a quick fix. For the honey, agave nectar works in a pinch if you're avoiding raw honey. The vanilla extract can be swapped for vanilla bean paste if you want extra depth. For the toasted coconut flakes, toast them in a dry pan for 2-3 minutes until golden—this makes all the difference in flavor.

Store the baked cake in an airtight container for up to 4 days at room temperature or 1 week in the fridge. The coconut cream swirl keeps best when the cake is chilled. For serving, I always dust with powdered sugar and add fresh mint leaves—it elevates the presentation instantly. The dessert reheats beautifully, so warm slices for 10-15 seconds if you prefer it warm. Freezes well for 3 months if wrapped tightly in plastic wrap.

Step-by-step instructions for black rice coconut cream dessert

Transform simple ingredients into a stunning purple velvet dessert with this precise method.

First, drain the soaked black rice thoroughly and transfer it to a food processor. Pulse until you achieve a fine, flour-like consistency—this is crucial for achieving that signature silky texture. The rice should resemble coarse sand rather than whole grains.

In a medium saucepan, combine the ground black rice with the 13.5 oz unsweetened coconut milk and 1 cup granulated sugar. Stir well to dissolve the sugar completely, then bring the mixture to a gentle boil over medium heat. Once boiling, immediately reduce the heat to low and let it simmer for 10-12 minutes, stirring frequently to prevent sticking. You'll notice the mixture thicken into a smooth, velvety paste with a deep purple hue—this is your flavor foundation.

While the rice mixture is still warm (but not hot), remove it from the heat and let it cool slightly for 2-3 minutes. In a separate bowl, whisk together the 4 whole large eggs until frothy. Slowly pour the warm rice mixture into the eggs while whisking constantly to create a smooth batter. This gradual incorporation prevents the eggs from scrambling.

Next, add the 0.5 cup melted unsalted butter and 1 tbsp vanilla extract, whisking until fully combined. The mixture should be thick and glossy, with a vibrant purple color. Stir in the 1 tsp baking powder and 0.5 tsp salt until just incorporated. Real talk: this is where the magic happens—the combination of the rice's natural starch and the coconut milk creates a texture unlike any other dessert.

In a small bowl, combine the 1 cup coconut cream with 2 tbsp honey. Whisk until smooth and set aside. Pour half of the egg mixture into a 9-inch round baking dish, spreading it evenly. Using a knife or spoon, create a well in the center of the batter. Pour the coconut cream mixture into this well, then gently swirl it into the batter using the tip of the knife in a circular motion. This creates those beautiful marbled patterns.

Finally, pour the remaining egg mixture over the swirled coconut cream, spreading it evenly. The contrast between the deep purple base and the lighter coconut cream will be stunning. Gently tap the baking dish on the counter to release any air bubbles that may have formed during pouring.

Preheat your oven to 350°F. Bake the dessert for 35-40 minutes, or until the center is just set but still slightly jiggly when gently shaken. The edges should be golden brown, and a toothpick inserted in the center should come out with a few moist crumbs—not wet batter. Your oven might run hot, so start checking at the 30-minute mark—this dessert is delicate and can go from perfect to overdone quickly.

Once baked, let the dessert cool completely in the oven with the door slightly ajar. This slow cooling prevents cracking and allows the flavors to meld beautifully. The contrast between the warm, spiced coconut cream and the cool, velvety rice base will be incredible.

Once completely cooled, sprinkle the top evenly with 0.5 cup toasted coconut flakes and garnish with 0.25 cup chopped fresh mint leaves. The toasted coconut adds a delightful crunch, while the mint provides a refreshing contrast to the rich coconut and rice flavors. For an extra touch, you can drizzle a little extra honey in a zigzag pattern over the top.

Slice into wedges and serve at room temperature. Each bite should deliver a perfect balance of textures—creamy, slightly chewy rice with pockets of rich coconut cream. The deep purple color makes this dessert as visually stunning as it is delicious, perfect for special occasions or when you want to impress with minimal effort.

Essential equipment for black rice dessert

Essential Kitchen Tools

Start with a high-quality food processor—I swear by the Ninja BN601—to grind the black rice into a fine powder. This step is non-negotiable for that signature silky texture.

A medium saucepan with a tight-fitting lid is perfect for simmering the rice mixture, while a whisk (preferably a balloon whisk) ensures your egg batter is light and airy. 🌾

Baking Essentials

Your 9-inch round baking dish should be made of ceramic or metal—glass can cause uneven baking. I use a Wilton Perfect Results dish for consistent results. A baking sheet is useful for toasting coconut flakes, and a spatula helps spread the batter evenly.

Don’t skip the oven thermometer—some ovens run hot, and this dessert needs precise temperature control.

Mixing and Garnishing

A small mixing bowl (about 2-cup capacity) is ideal for combining the coconut cream and honey. For swirling, a long, thin knife or spoon works best—just like frosting a cake. A fine-mesh sieve helps dust powdered sugar evenly, and sharp kitchen shears make quick work of chopping mint leaves.

Pro tip: Use two mixing bowls—one for the batter and one for the coconut cream—to avoid cross-contamination.

Optional Upgrades

If you love presentation, a piping bag with a star tip lets you create elegant coconut cream swirls. For extra precision, a digital kitchen scale ensures accurate measurements, especially for the black rice.

A stand mixer (like a KitchenAid Artisan) can save time when blending ingredients, though it’s not required. For serving, individual dessert plates with a dark rim make the purple color pop even more.
