Whip the egg whites with a hand mixer until stiff peaks form.
Gradually add sugar in 2-3 portions while whipping to make meringue.
In a bowl, mix matcha powder, almond flour, baking powder, and salt together evenly.
Sieve the tofu and mash it finely, then mix it with milk.
Add the dry mixture and tofu mixture to the meringue and gently fold with a spatula.
Pour the batter into a cake mold and bake in a preheated oven at 170°C for 25 minutes.
Let the cake cool, then make the cream by mixing matcha powder and stevia into Greek yogurt.
Spread the matcha cream evenly over the cooled cake.
