Preheat your oven to 350°F (175°C). Line a baking tray with parchment paper.
In a mixing bowl, whisk together the flour, matcha powder, sugar, baking powder, baking soda, and salt.
In another bowl, mix the almond milk, vegetable oil, and vanilla extract. Pour the wet ingredients into the dry ingredients and mix until just combined.
Pour the batter into the prepared baking tray and spread it evenly. Bake for 12-15 minutes or until a toothpick inserted into the center comes out clean.
While the cake is baking, prepare the filling. Whip the chilled coconut cream with powdered sugar and vanilla extract until fluffy.
Once the cake is done, let it cool slightly. Then, carefully roll the cake with the parchment paper and let it cool completely.
Unroll the cooled cake and spread the coconut cream filling evenly. Roll the cake back up without the parchment paper.
Chill the rolled cake in the fridge for at least 1 hour before slicing and serving.
