Twice-Baked Almond Croissants
A French bakery trick for rescuing day-old croissants: soak them in vanilla syrup, fill and top them with almond cream, then bake again until the edges caramelize and the almonds toast. The inside turns custardy and the top gets crisp, especially under a heavy snowfall of powdered sugar.

Method
Step 1: Simmer the water and 50 g sugar until dissolved, then take off the heat, add the vanilla and let the syrup cool while you make the filling. Heat the oven to 350F and line a baking sheet with parchment.
Step 2: Beat the butter and 100 g sugar until creamy, then beat in the almond flour, eggs one at a time, all-purpose flour, almond extract and salt until smooth and spreadable, about 2 minutes.
Step 3: Split each croissant horizontally with a serrated knife, leaving the back edge attached like a hinge. Brush the cut sides generously with syrup until moist but not falling apart.
Step 4: Spread about 1 1/2 tbsp almond cream inside each croissant and close it. Spread a thin layer of the remaining cream over the tops and press on the sliced almonds.
Step 5: Bake 18 to 22 minutes, until the almond cream on top is set and golden, the almonds are toasted and any cream that oozed onto the parchment has turned brown and crisp.
Step 6: Cool 10 minutes on the sheet, then dust heavily with powdered sugar right before serving.
Kitchen note
Stale croissants work better than fresh ones because their dried-out layers drink up the syrup like a sponge without collapsing, so the second bake crisps them instead of turning them soggy.
Easy swap
Add 1 tbsp dark rum or orange liqueur to the cooled syrup for a grown-up version.
