Make the Lemon Curd
Fill a saucepan with about 2 inches of water and bring to a simmer. Place a heat-safe bowl over the pot to create a double boiler.
Whisk egg yolks, sugar, lemon juice, zest, and salt in the bowl.
Cook over medium-low heat, whisking constantly, until thick enough to coat the back of a spoon (6–8 minutes).
Remove from heat and press plastic wrap directly onto the surface. Cool completely before using.
Make the Whipped Date Butter
Blend dates with a splash of warm water until completely smooth.
Whip softened butter with milk until pale and fluffy (2–3 minutes).
Add date paste and salt. Whip again until light and fully incorporated.
Chill briefly if too soft, then transfer to a piping bag.
Make the Lavender Mascarpone Cream
Warm heavy cream gently (do not boil). Remove from heat and stir in lavender.
Cover and steep 5–7 minutes. Strain out lavender if desired and chill cream completely.
Whip infused cream to soft peaks.
Gently fold in mascarpone, powdered sugar, and vanilla until smooth and fluffy.
Refrigerate until ready to assemble.
Make the Crêpes
Whisk flour, eggs, milk, vanilla, lemon zest, melted butter, and salt until smooth and lump-free.
Heat an 8-inch skillet over medium heat and lightly butter.
Pour about ¼ cup batter into the pan, swirling to coat thinly.
Cook 45–60 seconds until edges lift and bottom is lightly golden. Flip and cook another 20–30 seconds.
Repeat with remaining batter.
Assemble
Spread 1–2 tablespoons lemon curd onto each crêpe and fold into quarters.
Top with a generous dollop of lavender mascarpone cream and flatten slightly with the back of a spoon.
Pipe whipped date butter into the center.
Finish with powdered sugar and edible flower petals, if desired.
