These steps look super long, but this is SO EASY once you get going!
Place one crepe on the edge of your work surface.
Place 2 tbsp of pastry custard in the center of your crepe.
Next, fold crepe in half moon shape, by folding in half once, to the left.
Repeat these steps with half the stack of crepes, creating a crepe chain, layering the end of each crepe on top of the last, so each overlaps by 1".
Place a dab of custard on each end of your layered "chain" of crepes.
Beginning with the last crepe, carefully roll the crepes from one end of the chain to the beginning, creating a rosette.
Carefully turn the crepe roll 90 degrees, and set on on a flat plate, on the "flat side" or "bottom" of the rosette, for it to "stand up".
Chill now, in the freezer for 10 minutes, while you fill the rest of your crepes, creating half moons filled with Vanilla Pastry Custard.
Now you will spread 1 tsp of Vanilla Pastry Custard along the flat edge of each "half moon" stuffed crepe.
Going around the rosette in a circle, paste each crepe "half moon" to the rosette, until all the crepes are attached and the rosette is a full size rose.
Once the cake is complete, place it in the freezer to chill for 30 minutes.
To serve garnish and serve, transfer the cake to a pedestal or cake plate. Gently fold the tops of the crepe "petals" outward to give it a realistic look.
Garnish as desired, dust with cocoa powder, powdered sugar, cinnamon, serve with whipped cream, blackberries, etc.
