Preheat the airfryer to 180 degrees Celsius. Wash the strawberries, remove the hulls, and slice them. Mix them with agave syrup and spread them in a baking accessory or an oven-safe dish that fits in your airfryer. Roast for 15 minutes at 180 degrees Celsius. Then let cool completely.
Then set the airfryer to 160 degrees Celsius. Grease a cake tin well with butter and lightly dust with flour.
Beat the soft butter with the fine sugar, vanilla extract, and salt until creamy and fluffy.
Add the eggs one by one, mixing well each time to create a light batter.
Sift the flour and matcha powder over the batter and fold or briefly mix until smooth and lump-free.
Spoon the batter into the prepared baking tin and smooth the top.
Bake the cake in the airfryer at 160 degrees Celsius for approximately 55 minutes. Check if the cake is done with a skewer. If it comes out dry, the cake is ready. Let the cake rest in the tin for 10 minutes, then let it cool completely on a wire rack.
Meanwhile, finely blend the freeze-dried strawberries into a powder.
Whip the cold cream together with the icing sugar and strawberry powder until a light, loosely firm cream is formed.
Cut the completely cooled cake horizontally in half.
Spread the bottom half with half of the strawberry cream and top with some of the roasted strawberry compote.
Place the top cake half on top and finish with the rest of the strawberry cream. Spoon some more roasted strawberries over it and create nice swirls.
Finish with fresh raspberries and a little powdered sugar.
