Step 1 In a large mixing bowl, make jello according to the instructions on the package, but use 1/2 of the cold water. I.e. for a 6 oz package of jello, add 2 cups boiling water and 1 cup cold water. Let Jello sit at room temperature until it is soft set and jiggles a little (while you work on the rest of the cake), then beat in thawed 8oz cool whip.
Step 2 Line two 8" or 9" round cake pans (ideally one should be a springform pan) with parchment paper.
Step 3 In the bowl of an electric mixer with the whisk attachment, beat together 6 eggs and 1 cup sugar on high speed for 12 minutes or until 3 times in volume and thickened.
Step 4 Sprinkle flour over the top and use a spatula to gently fold in 1 cup all-purpose flour until all lumps are gone.
Step 5 Divide your batter in half between the 2 lined baking pans and bake at 350˚F for 16-20 min or until top is golden brown and toothpick comes out clean. Remove baked cake from the pan being careful not to squish the top and let it cool to room temperature on a wire rack. Wash the springform pan.
Step 6 Once your cake has cooled, place the skinnier layer back into the bottom of your springform pan.
Step 7 Slice your strawberries in half (or thirds if they are very large) and place them facing tightly against the walls of the springform pan.
Step 8 At this point, you'll want to beat 8oz cool whip into your jello which should be starting to thicken. Pour your jello cream over the bottom cake and strawberries being careful not to knock down the strawberries. Smooth over the top.
Step 9 Place the top biskvit layer over the top and refrigerate for 2 hours or until jello is set then remove from fridge to decorate.
Step 10 To decorate, beat together the cold heavy cream and powdered sugar until whipped and spreadable. I transferred it to a pastry bag and piped roses using a Wilton 2D tip. Start in the center and work your way out in circles; staying close to the surface of the cake.
Step 11 Pile fruit in the center in whatever design you like; they look good just piled up too. Put back in the fridge a couple more hours or overnight to allow the jello to fully set before serving or the cake will be too dainty and will fall apart easier when sliced. Also, you take it out of the spring form mold, fold some plastic wrap and wrap it around the jello part of this cake to keep it in place while it firms up fully.
