Mix all the crepe ingredients together except the eggs and beat until very smooth (no lumps). Beat the eggs in a separate bowl, then whisk into the crepe batter until completely incorporated.
Over a medium high heat burner, add 1 teaspoon vegetable oil to a hot 10-inch non-stick pan. Use a paper towel to quickly spread it around, and remove any visible pooling oil.
Fill a ½ cup measuring cup almost full of crepe batter. Hold the hot pan by the handle, and tilt it slightly then pour the batter into one side of the pan. Quickly but gently swirl the mixture in one direction around the pan so that it evenly coats the bottom of the pan, until it won’t swirl anymore. If the pan is the proper heat, this will take just 2-3 seconds.
Put the pan on the heated burner and allow to cook until the crepe looks dry – about 20 seconds. The edges of the crepe should pull away from the pan.
Use a spatula to gently flip the crepe, then cook for about 20 more seconds. Check the underneath side to make sure it’s cooked and slightly golden. Remove crepe from the pan and place on wax paper. Continue until all the batter is gone, layering wax paper between each crepe. Allow crepes to completely cool.
For The Cake:
Make a strawberry lemon creme by mixing lemon juice, powdered sugar and mascarpone together in a medium size bowl and set aside. Whip the heavy cream until soft peaks form. Add the mascarpone mixture to the whipping cream, and gently fold together until completely mixed. Add the pureed strawberries and mix on low until thoroughly mixed together.
Once crepes are cool you can assemble the cake. Start with one crepe face-down on a cake plate or serving dish. Spread two heaping tablespoons of strawberry lemon creme evenly over each crepe.
Add the next crepe and continue until cake is assembled.
Spread the remaining strawberry lemon creme on the top of the cake. The top layer should be much thicker than the other cream layers.
Top with whole or sliced strawberries, chill for 30 minutes, and enjoy.
NOTE: This cake is not overly sweet, by design. It’s more of a light creamy dessert. If you prefer desserts on the sweeter side, I recommend alternating between the Strawberry Lemon Mascarpone mixture, and seedless strawberry jam when assembling the cake. You will only need to make half of the creme mixture in the recipe if you choose to do this. Use only two level tablespoons of jam for every other crepe layer, and two heaping tablespoons of strawberry lemon creme mixture for the others. Top with the remaining creme, and strawberries.
