Dot Cake Matcha: Easy Japanese Marble Cake Recipe

Dot cake matcha is a Japanese-style marble cake where a plain vanilla batter is dotted with spoonfuls of matcha batter, then swirled just a few times to create a beautiful green-and-white pattern. The combination of rich, earthy matcha and sweet, buttery cake makes it a lovely treat for tea time. This recipe uses a simple chiffon-style method for a light, tender crumb that stays moist for days.

Ingredients

4 large eggs (about 200 g), separated, at room temperature
1/2 cup (100 g) granulated sugar, divided
1/2 cup (120 ml) whole milk, at room temperature
1/4 cup (60 ml) vegetable oil (or neutral oil like canola)
1 tsp vanilla extract
1 cup (120 g) cake flour (or all-purpose flour, see Tips)
1 tsp baking powder
1/4 tsp salt
1 tbsp (8 g) matcha powder (culinary grade)
1 tbsp (15 ml) hot water (for dissolving matcha)

Instructions

Preheat your oven to 350°F (175°C). Line the bottom of a 9-inch (23 cm) round cake pan with parchment paper, but do not grease the sides.
In a small bowl, dissolve the matcha powder in the hot water. Stir until smooth and set aside to cool.
In a medium bowl, whisk together the cake flour, baking powder, and salt. Set aside.
In a large mixing bowl, beat the egg yolks with half of the sugar (1/4 cup / 50 g) until pale and thick, about 2 minutes. Add the milk, oil, and vanilla extract, and whisk until combined.
Sift the flour mixture into the yolk mixture and whisk until just smooth. Do not overmix.
In a separate clean bowl, beat the egg whites with an electric mixer on medium speed until foamy. Gradually add the remaining 1/4 cup (50 g) sugar while beating. Increase speed to high and beat until stiff peaks form (the whites should stand straight up when the beater is lifted).
Gently fold one-third of the egg whites into the yolk mixture with a rubber spatula to lighten it. Then fold in the remaining whites until no streaks remain. Be careful not to deflate the batter.
Transfer about 1 cup (240 ml) of the batter to the bowl with the dissolved matcha. Fold gently until the matcha is fully incorporated, creating the green batter.
Pour the plain batter into the prepared pan. Drop spoonfuls of the matcha batter randomly over the top. Use a knife or skewer to swirl the batters together with 4-5 figure-eight motions. Do not over-swirl or the pattern will disappear.
Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean. The top should be golden brown and spring back when lightly pressed.
Remove from the oven and immediately invert the pan onto a wire rack. Let it cool completely upside down (this helps prevent sinking). After about 1 hour, run a knife around the edges and release the cake.

Tips

Flour substitution: If you don’t have cake flour, use 1 cup (120 g) all-purpose flour minus 2 tablespoons (about 16 g), and add 2 tablespoons (16 g) cornstarch. Sift together before using.
Matcha quality: Use culinary-grade matcha, not ceremonial grade (which is more delicate and expensive). Ceremonial grade will work but may taste more bitter.
Do not overmix: When folding the egg whites, use a gentle hand. Overmixing deflates the batter and makes the cake dense.
Cooling upside down: This is essential for a chiffon-style cake to prevent sinking. If your pan has a removable bottom, invert it onto a bottle neck or wire rack.

Serving Suggestions

Serve this cake at room temperature with a cup of hot green tea or a light oolong. It also pairs well with a dollop of lightly sweetened whipped cream and fresh berries. For a dessert, dust the top with a little extra matcha powder just before serving.

Variations

Chocolate matcha: Replace the matcha with 1 tablespoon (8 g) unsweetened cocoa powder dissolved in 1 tablespoon (15 ml) hot water.
Citrus matcha: Add 1 teaspoon of grated lemon or orange zest to the yolk mixture for a bright, fresh flavor.
Gluten-free: Substitute the cake flour with a gluten-free all-purpose blend that contains xanthan gum. The texture will be slightly denser.

Storage and Reheating

Store the cake in an airtight container at room temperature for up to 3 days. For longer storage, wrap it tightly in plastic wrap and refrigerate for up to 5 days (bring to room temperature before serving). You can also freeze the unfrosted cake for up to 2 months; wrap in plastic wrap and then foil. Thaw overnight in the refrigerator. To reheat, microwave individual slices for 10-15 seconds or warm in a 300°F (150°C) oven for 5 minutes.

Frequently Asked Questions

Can I use all-purpose flour instead of cake flour? Yes, but the cake will be slightly denser. To mimic cake flour, remove 2 tablespoons of flour per cup and replace with cornstarch, as described in Tips.

Why did my cake sink in the middle? This usually happens if the egg whites were overbeaten (they become dry and break) or if the batter was overmixed after adding them. Also, opening the oven door during baking can cause a sudden temperature drop. Make sure to cool the cake upside down.

Can I make this cake without separating eggs? Yes, you can use the whole-egg method: beat 4 whole eggs with all the sugar until thick and pale, then add liquids and dry ingredients. The texture will be more like a pound cake, less airy.

How do I get a stronger matcha flavor? Increase the matcha to 1.5 tablespoons (12 g) but keep the same amount of hot water. Be aware that more matcha can make the cake slightly bitter.

Can I use a loaf pan instead of a round pan? Yes, use a 9×5-inch (23×13 cm) loaf pan. Baking time will be longer, about 40-45 minutes. Check with a toothpick.

Is this cake safe for pregnant women? Yes, as long as the eggs are fully cooked (the cake reaches an internal temperature of 160°F / 71°C, which it does during baking). Matcha contains caffeine, so consume in moderation.
