Preheat your oven to 350°F (175°C).

Line your baking pan with parchment paper.

In a mixing bowl, whisk the eggs and granulated sugar until pale and fluffy.

In another bowl, sift together the flour, matcha powder, salt, and baking powder.

Gently fold the dry ingredients into the egg mixture.

In a separate bowl, whip the heavy cream until soft peaks form.

Fold the whipped cream into the matcha batter gently.

Pour the batter into the prepared baking pan and smooth the top.

Bake for 25 minutes or until edges are set and center is slightly springy.

Let the cloud cool completely before slicing.
