store bought dessert

We've all seen the cases filled with sad fruit tarts, stale cupcakes and cakes that are a bit past their prime. I decided to give a classic custard fruit tart a face lift and turn it into the boujee french dessert called mille-feuille (pronounced meal foyyy, for all of the non-French speakers like myself). It's got beautiful layers of crisp, buttery cookie, soft and creamy vanilla mousse and a bright, tart berry coulis!
