What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most are pantry staples, and the umami miso frosting is surprisingly easy to whip up.

• For the Cake Batter:
• All-purpose flour – 1 ¾ cups (220g)
• Unsweetened cocoa powder – ¾ cup (75g), preferably Dutch-processed for rich flavor
• Baking powder – 1 ½ teaspoons
• Baking soda – 1 ½ teaspoons
• Salt – ½ teaspoon
• Sugar – 2 cups (400g), granulated
• Large eggs – 2, room temperature (adds richness and structure)
• Whole milk – 1 cup (240ml), or dairy-free alternative if needed
• Vegetable oil – ½ cup (120ml), for moist crumb
• Vanilla extract – 2 teaspoons, real vanilla for best aroma
• Boiling water – 1 cup (240ml), intensifies chocolate flavor
• For the Umami Miso Frosting:
• Unsalted butter – 1 cup (227g), softened
• Powdered sugar – 3 cups (360g), sifted for smoothness
• White miso paste – 2 tablespoons (I recommend using a mellow, sweet white miso)
• Heavy cream – 2-3 tablespoons (30-45ml), adjusts frosting consistency
• Vanilla extract – 1 teaspoon

If you prefer, almond flour can be used to make the cake gluten-free, though texture will be slightly denser. For dairy-free frosting, swap butter with vegan margarine and heavy cream with coconut cream. I find that using white miso over red or brown keeps the frosting balanced and approachable for most palates.

Equipment Needed

• Two 9-inch (23cm) round cake pans – non-stick or lined with parchment paper for easy release
• Mixing bowls – at least two, one for dry ingredients and one for wet
• Electric mixer or stand mixer – helps achieve smooth batter and silky frosting
• Measuring cups and spoons – for precise ingredient amounts
• Rubber spatula – for folding and scraping bowls clean
• Whisk – handy for combining dry ingredients evenly
• Cooling racks – to cool cakes completely before frosting

If you don’t have a stand mixer, a hand mixer works just fine (I’ve made this cake countless times with both). For budget-friendly options, silicone spatulas and basic metal pans do the trick without compromising results. Just make sure pans are well-greased or lined to prevent sticking.

Preparation Method

1. Preheat your oven to 350°F (175°C). Grease and flour two 9-inch cake pans or line them with parchment paper. This helps the cake release easily once baked.
2. Combine dry ingredients. In a large mixing bowl, sift together 1 ¾ cups all-purpose flour, ¾ cup cocoa powder, 1 ½ teaspoons baking powder, 1 ½ teaspoons baking soda, and ½ teaspoon salt. Whisk well to distribute evenly. This step ensures your cake layers rise nicely and have a uniform crumb.
3. Mix wet ingredients. In a separate bowl, beat 2 large eggs with 2 cups sugar until slightly fluffy. Add 1 cup whole milk, ½ cup vegetable oil, and 2 teaspoons vanilla extract. Whisk until combined but don’t overbeat—just enough to blend.
4. Combine wet and dry mixtures. Gradually add the dry ingredients to the wet mixture, stirring gently with a spatula or mixer on low speed. The batter will be thick but smooth.
5. Add boiling water carefully. Slowly pour in 1 cup boiling water while mixing on low. The batter will thin out—this is normal and helps intensify the chocolate flavor. Don’t skip this step!
6. Pour batter into pans. Divide batter evenly between the two prepared pans. Tap the pans gently on the counter to release any air bubbles.
7. Bake for 30-35 minutes. Insert a toothpick into the center; it should come out with a few moist crumbs but no wet batter. Avoid overbaking, or the cake will dry out.
8. Cool completely. Remove cakes from oven and let them cool in pans for 10 minutes. Then transfer to cooling racks and let cool fully before frosting. Patience here is key to prevent frosting melt.
9. Prepare the umami miso frosting. In a large bowl, beat 1 cup softened unsalted butter until creamy. Gradually add 3 cups powdered sugar, mixing on low to avoid clouding your kitchen. Add 2 tablespoons white miso paste and 1 teaspoon vanilla extract, then 2-3 tablespoons heavy cream to achieve desired spreadability. Beat until fluffy and smooth.
10. Assemble the cake. Place one cake layer on your serving plate. Spread a generous amount of frosting evenly on top. Add the second layer, then frost the top and sides of the cake. Use a spatula to create swirls or smooth the surface as you like.
11. Chill and serve. Chill the cake for at least 30 minutes to set the frosting. This step enhances the flavors and makes slicing easier.

Pro tip: If your frosting feels too thick, add a splash more cream; if too thin, a dusting of powdered sugar helps. If you accidentally overmix, the frosting might become too soft—pop it in the fridge for 15 minutes to firm up.

Cooking Tips & Techniques

Here’s what I’ve learned from many batches of this decadent chocolate cake with umami miso frosting:

• Don’t skip sifting dry ingredients. It keeps the cocoa powder from clumping and ensures even leavening.
• Use room-temperature eggs and milk. It helps the batter mix smoothly without curdling or lumps.
• Adding boiling water might feel weird, but trust it. It blooms the cocoa powder and yields that moist, tender crumb.
• When mixing frosting, start slow. Powdered sugar can fly everywhere otherwise. I’ve learned this the hard way!
• White miso paste is key. Red or brown miso can overpower the frosting with saltiness.
• Always cool your cake layers completely. Warm cake plus frosting equals melty mess.
• For best slicing, chill the cake before serving. It firms up the frosting and helps keep clean edges.

Timing-wise, prep the frosting while the cake cools to multitask smarter. And if the frosting gets too soft during assembly, a quick chill saves the day. Honestly, I’ve had a few frosting fails, but patience and these little tricks keep things on track every time.

Variations & Adaptations

This decadent chocolate cake with umami miso frosting is surprisingly versatile, and you can tweak it to suit your mood or dietary needs:

• Vegan Version: Use flax eggs (1 tablespoon ground flax + 3 tablespoons water per egg) and swap milk for almond or oat milk. Replace butter with vegan margarine and use coconut cream in the frosting.
• Seasonal Twist: Add ½ cup fresh raspberries or chopped strawberries to the batter for a burst of fruity freshness. You can also sprinkle chopped nuts on top of the frosting for crunch.
• Gluten-Free: Swap all-purpose flour for a gluten-free blend (like Bob’s Red Mill 1-to-1). The texture will be slightly denser but still delicious.
• Different Frosting: If you want a lighter touch, try mixing miso paste into whipped cream or cream cheese frosting. It’s a subtle umami surprise without the richness of buttercream.

Personally, I once tried adding a teaspoon of espresso powder to the batter for an enhanced chocolate depth—totally worth it if you love mocha vibes. The miso frosting still stole the show, though!

Serving & Storage Suggestions

This cake is best served slightly chilled or at room temperature. The frosting is creamy yet firm enough to hold beautiful swirls or rustic spreads. Pair it with a cup of freshly brewed coffee or a glass of cold milk for pure bliss.

For storage, cover the cake loosely with plastic wrap or keep it in an airtight container. It stays fresh in the refrigerator for up to 4 days. To freeze, wrap the frosted cake tightly in plastic and foil; it lasts up to 2 months. Thaw overnight in the fridge before serving.

Reheating? This cake is best enjoyed cold or at room temp, but if you prefer a warm slice, microwave a piece for 10-15 seconds. The frosting softens nicely, but don’t go too long or it might get melty.

Fun fact: The flavors actually deepen after a day or two, as the miso and chocolate mingle. So if you can wait, your patience pays off!
