Decadent Matcha Foam Opera Cake Recipe in 3 Easy Steps

Oh my gosh, you guys—I still remember the first time I tasted matcha foam opera cake at this tiny Parisian patisserie. The delicate layers of matcha sponge practically melted on my tongue, while that cloud-like foam topping made me feel like I was eating a sweet green tea dream. I’ve been obsessed ever since! This isn’t your grandma’s opera cake—it’s a modern twist on the French classic where earthy matcha plays perfectly with sweet cream. What I love most is how the vibrant green layers look stunning yet taste so light. Trust me, one bite and you’ll understand why I had to recreate this magic at home!

Why You’ll Love This Matcha Foam Opera Cake

Let me count the ways this cake will steal your heart—starting with that first heavenly bite! The magic happens when:

• The matcha sponge practically dissolves on your tongue—so airy it’s like eating green tea clouds
• Real ceremonial-grade matcha gives that perfect earthy-sweet balance (no bitter aftertaste here!)
• Each slice shows off those gorgeous green-and-white layers—almost too pretty to eat (almost!)
• It feels fancy but secretly comes together faster than you’d think (shh, our little secret)

Seriously, this cake turns any Tuesday into a special occasion. Just wait till you see your friends’ faces when you bring this beauty to the table!

Matcha Foam Opera Cake Ingredients

Here’s the secret lineup that makes this cake sing – and yes, every single ingredient matters! I learned the hard way that skimping on quality or skipping prep steps can turn this delicate dessert into a sad, dense mess. (Ask me about my “matcha pancake” disaster of 2019…)

• 1 cup all-purpose flour (spoon & leveled – no packing it down!)
• 1 tbsp matcha powder (ceremonial grade, sifted TWICE – trust me, it prevents lumps)
• 3 large eggs (room temp – cold eggs don’t whip up properly. I leave mine out for 30 mins)
• ½ cup granulated sugar (superfine if you can find it – dissolves like a dream)
• ¼ cup unsalted butter (melted but cooled – hot butter cooks the eggs. Oops.)
• 1 cup heavy cream (minimum 36% fat, and chill the bowl in the freezer first!)
• 1 tsp vanilla extract (the real stuff – no imitation here please)
• 1 tbsp powdered sugar (for that perfect lightly sweet foam)

See that matcha note? Splurge on the good stuff – the bright green color and smooth flavor make all the difference. I buy mine from a specialty tea shop and keep it in the freezer to stay fresh.

How to Make Matcha Foam Opera Cake

Okay, let’s make some cake magic happen! I’ll walk you through each step like I’m right there in your kitchen – apron on, whisk in hand, probably sneaking bites of matcha powder (just me?). This process breaks down into three beautiful stages: the sponge, the cream, and the grand assembly. Follow along and you’ll have a showstopper!

Preparing the Matcha Sponge

First, preheat your oven to 350°F (175°C) – no guessing here, use an oven thermometer if you’ve got one! Now grab that flour and matcha powder you sifted earlier (you did sift them together, right? Good!). The double-sifting makes all the difference for that ultra-light texture.

Here’s where the fun begins: beat those room-temp eggs and sugar for a full 5 minutes until they’re pale, thick, and form ribbons when you lift the whisk. This is your cake’s backbone! Now gently fold in the dry ingredients in three batches – I use a big silicone spatula and make figure-8 motions to keep all that precious air in the batter. Last, drizzle in the cooled melted butter while folding continuously. Pour into your prepared pan and bake exactly 20 minutes – set a timer! The sponge should spring back when lightly touched.

Whipping the Cream Layer

While the sponge cools, let’s make that dreamy cream layer. Here’s my pro tip: chill your mixing bowl and beaters in the freezer for 15 minutes first. Cold tools = happy whipped cream! Pour in your heavy cream and start whipping on medium speed – don’t rush this or you’ll get butter (been there!).

When soft peaks form, add the vanilla and powdered sugar. Keep whipping just until medium peaks form – the cream should hold its shape but still look silky. Overdo it and you’ll lose that gorgeous foam texture we’re after. Taste it? I won’t tell!

Assembling the Cake

Time for the grand finale! Slice your cooled sponge horizontally into two even layers – I use dental floss for the cleanest cut. Place the bottom layer on your serving plate and spread half the cream evenly with an offset spatula. Gently place the top layer and repeat with remaining cream.

Now the hardest part: refrigerate for at least 2 hours before serving. I know, the wait kills me too! But this chill time lets the flavors meld and makes slicing cleaner. Worth every agonizing minute, promise!

Expert Tips for the Perfect Matcha Foam Opera Cake

After more trial-and-error batches than I’d like to admit (RIP, my dense matcha brick of 2020), here’s what I’ve learned makes this cake truly sing:

• Matcha matters most – That grocery store matcha? Toss it. Only ceremonial-grade gives that vibrant color and smooth, earthy flavor without bitterness. I keep mine in the freezer to stay fresh.
• Fold like you mean it – Overmix that sponge batter and poof! There goes all the air. Gentle figure-8 folds with a silicone spatula are your best friend.
• Cream checkpoint – Whip just until medium peaks form. Undermixed cream slides right off the cake, overmixed turns grainy. Stop when it holds its shape but still looks glossy.
• Patience pays – I know it’s tempting, but don’t skip the chill time! Those 2 hours let the flavors marry and make slicing clean.

Follow these and you’ll avoid all my kitchen disasters – your cake will be pure matcha magic!

Matcha Foam Opera Cake Variations

Once you’ve mastered the classic version, let’s play with flavors! My favorite part of baking is tweaking recipes to create something new. Here are my go-to twists when I’m feeling adventurous:

• Espresso Matcha Fusion – Replace half the matcha with instant espresso powder for a coffee lover’s dream. The bitter notes make the sweetness pop!
• Tropical Coconut Cream – Swap the vanilla cream with coconut milk whipped cream (chilled overnight first). Top with toasted coconut flakes for crunch.
• Berry Surprise – Add a thin layer of raspberry jam between the sponge and cream. The tartness cuts through the matcha beautifully.

See? One recipe, endless possibilities. What variation will you try first?

Serving and Storing Matcha Foam Opera Cake

Oh, the joy of presenting this beauty! I always serve my matcha foam opera cake with piping hot jasmine tea—the floral notes dance perfectly with the earthy matcha. For extra flair, dust the top with matcha powder right before slicing (use that hot knife trick for clean cuts!).

Store leftovers (if you have any!) in an airtight container in the fridge for up to 3 days. The cream stays dreamy, but trust me—freezing ruins that perfect foam texture. Learned that the hard way after my “matcha ice cube cake” experiment!

Matcha Foam Opera Cake Nutritional Information

Okay, let’s be real—this isn’t health food (it’s cake, after all!), but here’s the scoop on what’s in each glorious slice. The numbers below are estimates per serving, but your exact counts might vary slightly based on ingredient brands. Watching sugar? Try reducing the powdered sugar in the foam by half—it still tastes amazing! Vegetarian friends can rejoice, but for gluten-free needs, swap the flour with your favorite 1:1 blend (I’ve had success with rice flour mixes). Mostly? Just enjoy every bite—life’s too short not to!

Frequently Asked Questions

Got questions? I’ve got answers! Here are the ones I hear most often (and asked myself about a dozen times when I first started making this cake):

Can I use almond flour instead of all-purpose?
You can, but the texture changes completely—it becomes denser and more fragile. If you go this route, add 1 extra egg white to help bind it. Personally? I’d stick with regular flour for that classic opera cake lightness.

Help! My whipped cream won’t thicken—what now?
Been there! First, make sure everything is ice-cold—bowl, beaters, even the cream. If it’s still runny after 5 minutes of whipping, add 1 tsp cornstarch while mixing. Still no luck? Chill everything for 15 minutes and try again. Hot kitchens are whipped cream’s worst enemy!

Why does my matcha sponge look dull green instead of vibrant?
That usually means your matcha powder oxidized (or wasn’t top quality to begin with). Always buy fresh, bright green ceremonial-grade matcha and store it in the freezer. Pro tip: sift it with the flour right before mixing to preserve that gorgeous color!
