Add a spoonful of custard to the base of the cup. Place a layer of pound cake. Then, add a spoonful of custard on top. Make sure it spreads on the cake.
Add a layer of strawberries. Then, top with a layer of custard. This layer is about two spoonfuls of custard.
Now, arrange the blueberries on top along the rim of the cup, so the layer is visible.
The final layer is whipped cream. You can just spread it on the top of the blueberries. If you have a piping bag, use that to make the top layer look prettier.
Garnish with chopped pistachios and dried rose petals.
