Mochi matcha cake is a wonderfully chewy, dense cake made from glutinous rice flour (mochiko) and flavored with vibrant green matcha powder. Unlike traditional Western cakes, this one has a delightfully sticky, bouncy texture that is both unique and addictive. It’s a perfect dessert for matcha lovers and anyone looking to try something new, and it’s surprisingly simple to make with just a whisk and a baking pan.
Ingredients
- 1 ½ cups (360 ml) whole milk, at room temperature
- 3 large eggs, at room temperature
- 1 cup (200 g) granulated sugar
- ½ cup (115 g) unsalted butter, melted and slightly cooled
- 1 teaspoon vanilla extract
- 1 ½ cups (210 g) mochiko (glutinous rice flour)
- 1 tablespoon (8 g) matcha powder (culinary grade)
- 2 teaspoons baking powder
- ¼ teaspoon salt
Instructions
- Preheat your oven to 350°F (175°C). Grease an 8-inch (20 cm) square baking pan with butter or line it with parchment paper.
- In a large mixing bowl, whisk together the milk, eggs, sugar, melted butter, and vanilla extract until the sugar is mostly dissolved and the mixture is smooth.
- In a separate bowl, sift together the mochiko, matcha powder, baking powder, and salt. This helps remove any lumps from the matcha and ensures even distribution.
- Gradually add the dry ingredients to the wet ingredients, whisking continuously until the batter is completely smooth. There should be no dry pockets of flour remaining. The batter will be quite thin, similar to a crepe batter.
- Pour the batter into the prepared pan. Tap the pan gently on the counter a few times to release any air bubbles.
- Bake for 45–55 minutes, or until the top is a deep golden brown and a toothpick inserted into the center comes out clean. The edges will pull away from the pan slightly. (If the top browns too quickly, loosely cover with foil after 30 minutes.)
- Let the cake cool in the pan on a wire rack for at least 20 minutes before slicing. It will firm up as it cools but remain chewy. Slice into 9 squares and serve warm or at room temperature.
Tips
- Use the right flour: Mochiko (glutinous rice flour) is essential. Do not substitute regular rice flour or all-purpose flour, as the texture will be completely different. It is available in most Asian grocery stores or online.
- Room temperature ingredients: Make sure your eggs and milk are at room temperature. This helps the batter come together smoothly and prevents the melted butter from solidifying into lumps.
- Don’t overmix: While you want a smooth batter, overmixing can develop too much gluten (if using a blend) or make the cake gummy. Mix just until no dry streaks remain.
- Check for doneness: The cake will look slightly shiny on top when done. A toothpick inserted in the center should come out with a few moist crumbs, but not wet batter. If it comes out clean, it’s ready.
Serving Suggestions
Serve this mochi matcha cake as a delightful afternoon tea treat. It pairs beautifully with a cup of hot green tea or a matcha latte. For a more indulgent dessert, serve it with a scoop of vanilla ice cream, a drizzle of sweetened condensed milk, or a dollop of lightly sweetened whipped cream. You can also dust the top with a little extra matcha powder just before serving for a more vibrant color.
Variations
- Chocolate Mochi Cake: Replace the matcha powder with 2 tablespoons (15 g) of unsweetened cocoa powder and add ½ cup (85 g) of chocolate chips to the batter.
- Citrus Mochi Cake: Add the zest of one lemon or orange to the wet ingredients and reduce the vanilla extract to ½ teaspoon. This adds a bright, fresh flavor that complements the chewy texture.
- Add-ins: Fold in ½ cup (60 g) of white chocolate chips, chopped macadamia nuts, or sweetened red bean paste (anko) for extra texture and flavor.
- Vegan Version: Substitute the milk with unsweetened almond or oat milk, the eggs with 3 tablespoons (45 ml) of aquafaba (chickpea brine), and the butter with coconut oil. The texture will be slightly less rich but still chewy.
Storage and Reheating
Store leftover mochi matcha cake in an airtight container at room temperature for up to 2 days, or in the refrigerator for up to 4 days. The cake will become firmer when chilled. To restore its soft, chewy texture, microwave individual slices for 10–15 seconds, or wrap the entire cake in foil and warm it in a 300°F (150°C) oven for 5–10 minutes. This cake also freezes well; wrap it tightly in plastic wrap and freeze for up to 2 months. Thaw overnight in the refrigerator and reheat as directed.
Frequently Asked Questions
Can I use sweet rice flour instead of mochiko? Yes, sweet rice flour is the same as mochiko. It is often labeled as “glutinous rice flour” or “sweet rice flour.” Just make sure it is the fine, powdery type, not the coarse rice flour used for regular rice cakes.
Why is my cake too dense or gummy? This cake is meant to be dense and chewy, but if it is overly gummy, you might have overmixed the batter or used too much liquid. Also, make sure you bake it long enough; underbaking can leave the center too sticky.
Can I reduce the sugar? Yes, you can reduce the sugar to ¾ cup (150 g) without affecting the texture much. However, keep in mind that sugar also helps with browning and moisture, so the cake may be slightly less tender and less sweet.
Can I use a different pan size? Yes, you can use a 9-inch (23 cm) round cake pan or a loaf pan. Adjust the baking time accordingly—a larger pan will bake faster, while a loaf pan may need a few extra minutes. Check for doneness with a toothpick.
Is matcha powder safe for everyone? Matcha contains caffeine, so it is not recommended for young children or individuals sensitive to caffeine. If you prefer a caffeine-free version, you can substitute the matcha with a caffeine-free green tea powder (like hojicha) or simply omit it and add extra vanilla.
Can I make this cake gluten-free? Yes, this cake is naturally gluten-free as long as you use mochiko (glutinous rice flour) and ensure your baking powder is gluten-free. Check the label on your baking powder to be sure.
