Make the Crêpe Batter
In a bowl, whisk flour, granulated sugar, and salt.
Add eggs and whisk until smooth.
Gradually whisk in milk until fully combined.
Stir in melted butter and vanilla extract.
Let batter rest 20–30 minutes for best texture.
Cook the Crêpes
Heat a nonstick skillet over medium heat and lightly grease.
Pour about ¼ cup batter into the center and swirl to coat thinly.
Cook 45–60 seconds until edges lift easily.
Flip and cook 20–30 seconds more.
Transfer to a plate and repeat with remaining batter.
Cool crêpes completely before assembling.
Make the Lemon Mascarpone Cream
Beat mascarpone cheese until smooth.
Add powdered sugar, lemon zest, lemon juice, and vanilla; mix until combined.
In a separate bowl, whip heavy cream to soft peaks.
Gently fold whipped cream into mascarpone mixture until smooth and spreadable.
Assemble the Cake
Place one crêpe on a serving plate or cake stand.
Spread a thin, even layer of lemon mascarpone cream on top.
Repeat with remaining crêpes and cream, stacking evenly.
Finish with a light layer of cream or dust with powdered sugar.
Chill & Serve
Refrigerate at least 2 hours (or overnight) before slicing.
Slice with a sharp knife and serve chilled.
