Whoopie pies
Soft chocolate cakes sandwiched with marshmallow-style buttercream
Whoopie pies are Maine's official state treat and a lunchbox favourite in Pennsylvania Dutch country too; you find them wrapped in cling film by the till at petrol stations and bake sales all over New England. Two domed, soft chocolate cakes hold a thick, fluffy white filling. This filling is a meringue buttercream, so there's no gelatine-based marshmallow. Chef's tip: pipe or scoop the batter in even mounds and leave room, as they spread to 8 cm.

Method
0/6 doneStep 1: Heat the oven to 375°F (350°F fan) and line two baking trays. Sift the 9 oz plain flour, 1 ¾ oz cocoa powder, 1 tsp bicarbonate of soda and ½ tsp salt together.
3 minStep 2: Beat the 4 oz butter and 7 oz soft brown sugar until fluffy, then beat in the 1 egg and 1 tsp vanilla extract. Mix in the dry ingredients and 1 cup buttermilk in turns to a thick batter.
5 minStep 3: Drop 24 heaped tablespoons onto the trays, 5 cm apart. Bake for 10–12 minutes, until the tops spring back when pressed. Cool completely on the trays.
15 minStep 4: For the filling, whisk the 2 egg whites and 4 oz sugar in a heatproof bowl over simmering water until the sugar dissolves and it feels hot, about 4 minutes.
4 minStep 5: Whisk off the heat for 6 minutes until thick, glossy and cool. Beat in the 6 oz butter a spoonful at a time, then the 1 tsp vanilla extract and 2 ⅛ oz icing sugar. A common mistake is adding butter while the meringue is warm, which makes it soupy.
8 minStep 6: Pair the cakes by size, spread or pipe a thick layer of filling on the flat side of half, and press the others on top.

Basque burnt cheesecake
This crustless cheesecake was created in the early 1990s at La Viña, a pintxos bar in the old town of San Sebastián (Donostia) in the Basque Country, and is now famous around the world. It's baked very hot so the top caramelises almost black and the sides rise and crack, while the middle stays soft and creamy, almost runny. There's no base and no water bath, and the rough, rustic look is the point: it's lined with crumpled baking paper. La Viña uses a spoonful of wheat flour; cornflour does the same job and keeps it gluten free. Chef's tip: take it out of the oven while the centre still wobbles like a soft set custard; it firms up as it cools, and if it looks set in the oven, the middle will be dry instead of creamy.
