Chef John's Strawberry Crepe Cake

1 . Stage

Pour eggs, flour, sugar, salt, oil, milk, and vanilla extract into a blender. Blend, starting on low speed and finishing on high, until combined. Refrigerate batter for at least 30 minutes.

2 . Stage

Scoop strawberry jam into a saucepan. Rinse out jar with water and pour into the saucepan. Bring to a simmer over medium heat and stir. Simmer for 1 minute, remove from heat, and stir. Let cool to room temperature.

3 . Stage

Brush some butter over a nonstick skillet over medium heat. Pour in 1/4 cup batter; tilt pan to coat evenly. Cook until crepes bubble and brown, about 1 1/2 minutes per side. Transfer to a baking sheet. Repeat with remaining batter, buttering the pan between crepes. Let cool completely before stacking, at least 15 minutes.

4 . Stage

Combine mascarpone cheese, cream, sugar, and vanilla extract in a bowl. Whisk together until stiff peaks form.

5 . Stage

Lay a crepe onto a large plate. Spoon on 2 or 3 tablespoons of the cream mixture, spreading it almost to the edge. Swirl in some strawberry jam. Transfer finished crepe onto a flat serving plate. Repeat with remaining crepes, cream, and jam. Center each crepe over the previous one in a stack. Gently press on a final plain crepe to finish.

6 . Stage

Refrigerate until completely chilled before cutting and serving.
