For the Whipped Cream, add heavy whipping cream to your mixer bowl and mix on high speed.
When peaks begin to appear, slowly add in cornstarch, confectioner's sugar and vanilla extract and whip until stiff peaks are formed.
To assemble stacks, pipe whipped cream on one cookie then add two strawberry slices. Top strawberries with another tea cake then repeat process two more times ending with whipped cream and berries on top layer. There should be three cookies and two whipped cream/berry layers per stack. Enjoy!
