If you want to make the whipped cream at home, then you need to take chilled, yes very chilled heavy cream
Beat continuously making bigger loops, so that more air gets in and you can get stiff peaks, it takes around 2-3 minutes, else you may use a mixer to beat the cream
Cut the cake in 2 slices and place the strawberry slices with cream on top. If you want to evenly spread the cream, you may use an icing cone.
Place the other cake piece on top of the cream and again top with whipped cream and strawberry pieces.
