In a Medium Pot, combine Egg Yolks and 3/4 cup Sugar. Whisk together until thoroughly combined.
Place Pot over Medium heat and slowly add the Milk, stirring until thoroughly combined.
Stirring continuously with a Whisk, bring to a boil.
Cook for about a minute more until it thickens.
Transfer to a large Mixing Bowl, cover with plastic wrap and let cool completely in the refrigerator.
Once completely cooled, slowly add Mascarpone cheese and mix with Hand Mixer until thick, creamy and thoroughly combined.
Cover and let sit in refrigerator until you’re ready to use it.
Make the Espresso Whipped Cream
In a large Mixing Bowl, add Heavy Whipping Cream, 2-3 Tablespoons Sugar, Vanilla, Kahlua (optional) and Instant Espresso.
Mix with Hand Mixer until thoroughly whipped into stiff peaks.
Cover and let sit in refrigerator until you’re ready to use it
Build the Tiramisu Crepe Cake
Place one Crepe on the bottom of a 10” Springform Pan. (NOTE: if you feel comfortable keeping the cake straight, remove the sides of the pan and build the cake free form. You can, of course, keep the sides of the Springform pan attached to help guide the cake at first.)
Place about 1/3 of cup of Mascarpone Custard and spread into a thin layer using the Offset Spatula.
Place a Crepe on top of the Mascarpone Custard.
Place about 1/3 of a cup of Espresso Whipped on the Crepe and spread into a thin layer using an Offset Spatula or Silicone Spatula
Place another Crepe on top of the Espresso Whipped Cream.
Repeat steps 2 through 5 until you build the size cake you want. (Note: Place in the Freezer for about 10 minutes for each 25 layers you are building.
After, the final Crepe, finish with a thick Layer (about 2/3 cup) of the Mascarpone Custard on top.
Freeze for about 30 minutes.
Using the mesh Strainer, dust with Cocoa Powder.
(Note: If building a larger cake, stick a Chopstick or skewer into the slice of cake to make it easier to remove from the pan without it falling apart.)
