1 stick unsalted butter, melted, plus more for greasing
One 14-ounce can coconut cream
2 cups mascarpone
1 cup confectioners' sugar
1 tablespoon lemon juice
1 teaspoon lemon zest
1 teaspoon kosher salt
Confectioners' sugar
Toasted coconut flakes
Lemon zest
Directions
Make the crepe batter: In a blender, combine all of the crepe ingredients and blend until smooth. Transfer to a bowl and chill for 1 hour.
After chilling, grease two 10-inch nonstick skillets and heat over medium heat. Staggering about 1 minute apart, add ¼ cup of the crepe batter to each pan and quickly swirl to coat the entire pan surface with a thin layer of batter. Cook until the crepe just begins to change color, 1 to 2 minutes, then flip and cook for 1 to 2 minutes more. Transfer to a plate to cool.
Continue the process, working between the 2 pans and stacking the cooked crepes on a plate to cool until you have 18 crepes total. Place the crepes in the refrigerator and chill for 1 hour.
Meanwhile, make the filling: In a large bowl, beat the coconut cream with an electric hand mixer until soft peaks form. Add the remaining filling ingredients and mix until smooth.
Assemble the cake: Once the crepes have chilled, grease a 9-inch springform pan with butter. Lay one crepe down on the bottom, then top with ¼ cup of the filling. Using a mini offset spatula, spread the filling into an even layer. Continue this process until all the crepes have been used. Cover with plastic wrap and refrigerate for 4 hours until the filling has set.
Use a paring knife to release the crepe cake from the springform pan. Garnish with confectioners' sugar, toasted coconut and lemon zest, then serve.
