Pro Tips
- Use culinary-grade or ceremonial-grade matcha for the best color and flavor — the cheap stuff turns bitter and dull olive green when heated
- Sift the matcha powder before mixing to prevent clumps that create bitter pockets in your cake
- Microwave in 30-second intervals instead of one long blast to avoid rubbery edges and ensure even cooking throughout
- Let it rest for 30 seconds after microwaving — the residual heat finishes cooking the center while the top sets to a tender, not-sticky texture
Quick Matcha Green Tea Mug Cake
Ingredients
Method
- In a microwave-safe mug (at least 12 ounces), sift together the flour, matcha powder, sugar, baking powder, and salt. Use a fork to ensure no lumps remain, especially with the matcha.
- Add the milk, oil, and vanilla extract to the mug. Whisk vigorously with a fork or small whisk for 30 seconds until the batter is completely smooth and no flour pockets remain at the bottom.
- Tap the mug gently on the counter 2-3 times to release any air bubbles. Smooth the top of the batter with the back of a spoon.
- Microwave on high power for 60-90 seconds, depending on your microwave wattage. The cake is done when the top looks set and springs back lightly when touched, but the center may still look slightly glossy.
- Let the mug rest for 30 seconds to finish cooking through with residual heat. The cake will pull away slightly from the sides of the mug.
- Top with whipped cream, fresh berries, a sprinkle of matcha powder, or enjoy it straight from the mug with a spoon.
Frequently Asked Questions
Can I bake this in the oven instead of the microwave?
Yes, pour the batter into a small oven-safe ramekin and bake at 350°F for 12-15 minutes until a toothpick comes out with just a few moist crumbs. The texture will be slightly denser but equally delicious.
What if my cake turns out rubbery?
You’ve microwaved it too long. Microwaves vary in power, so start with 60 seconds, then add 10-second bursts until the center is just set but still slightly jiggly. It firms up as it cools.
Can I use a different type of milk?
Absolutely — almond milk, oat milk, or coconut milk all work beautifully. Just avoid ultra-thick plant milks, which can make the texture too dense.
How do I know if my matcha is fresh enough?
Fresh matcha is vibrant green and smells grassy and sweet, not musty or brown-tinged. Store it in an airtight container in the fridge to preserve its color and flavor for up to 6 months.
Storage & Serving
This cake is best enjoyed immediately while it’s still warm and tender. If you do have leftovers, cover the mug with plastic wrap and refrigerate for up to 24 hours — reheat for 15-20 seconds in the microwave before serving. Top with a dollop of vanilla Greek yogurt and honey for breakfast, or go full dessert mode with sweetened whipped cream and fresh raspberries. A light dusting of powdered sugar or extra matcha makes it Instagram-worthy in seconds.
