Recipe by YouTuber Wonna. (You'll need 5 drops of vanilla oil)
Mix all the ingredients together.
Pour the batter into a heatproof container or mold.
The batter should reach about the width of one finger—this is just right!
Bake in the air fryer at 170°C for 10 minutes.
It's perfect if the center jiggles when you shake it!
Let it rest in the fridge for at least 3 hours, then enjoy your moist brownie!
