Make the crepe batter. In a bowl, whisk 1 cup flour, 2 tablespoons sugar, 1–2 tablespoons matcha, and a pinch of salt. In another bowl, whisk 3 large eggs, 2 cups whole milk, 2 tablespoons melted butter, and 1 teaspoon vanilla.
Whisk wet into dry until smooth. If lumpy, blend 10–15 seconds.
Rest the batter. Cover and chill 30–60 minutes. This step is key for tender crepes and fewer bubbles.
Heat the pan. Warm a nonstick pan over medium. Lightly brush with butter or oil, then wipe off excess.
The pan should be hot enough that batter sets in seconds.
Cook the crepes. Pour about 1/4 cup batter into the center, swirling to coat in a thin circle. Cook 45–60 seconds until the edges lift and the top looks set. Flip and cook 10–15 seconds more.
Transfer to a rack or parchment. Repeat, stacking with parchment if needed. Aim for 16–20 crepes.
Cool completely. Warm crepes will melt the cream.
Let them cool to room temperature before assembly.
Make the matcha cream. In a bowl, whisk 2 teaspoons matcha with 2 tablespoons powdered sugar to break up clumps. In a separate bowl, beat 8 ounces softened cream cheese with 1/3 cup powdered sugar until smooth (optional but adds stability). Add 1 cup heavy cream, 1 tablespoon cornstarch, 1 teaspoon vanilla, and the matcha mixture.
Beat to medium-stiff peaks. Taste and adjust sweetness.
Prep for assembly. Place a crepe on a flat plate or turntable. Have an offset spatula ready.
If your edges are uneven, trim crepes with a round cutter or a sharp knife using a plate as a guide.
Layer the cake. Add 2–3 tablespoons cream to the first crepe and spread thinly, leaving a small border. Top with another crepe, align edges, and repeat. Keep layers thin to avoid sliding. Stop before the last crepe to ensure you have enough cream.
Top and finish. Place the final crepe on top.
Smooth stray cream around the edges. Chill the cake at least 2–3 hours (or overnight) to set for clean slices.
Dust and serve. Right before serving, dust the top with a fine layer of matcha or powdered sugar. Slice with a sharp knife, wiping the blade between cuts.
