Lemon and oat Linzer biscuits

This recipe is for lovers of rustic textures. Adding oats to the Linzer dough gives the biscuit a crunchier, nuttier character whilst increasing its fibre content. The oats absorb the butter's flavour and toast to a golden brown during baking, creating a perfect contrast with the soft lemon jam.

Instructions

1

Mix the flour with the oats, icing sugar, and baking powder.

Tip: If the oat flakes are too large, give them a spin in the food processor so they blend better into the dough.
2

Rub in the cold butter, then add the egg, lemon juice, and zest. Knead together.

Tip: Oats can absorb more moisture than flour. If the dough is crumbly, add another drop of lemon juice or water.
3

Chill in the fridge for 30 minutes.

Tip: Oats need time to absorb moisture.
4

Roll out, cut out, and bake at 180°C (160°C Fan) for 12-15 minutes.

Tip: The surface of the biscuits will be more rustic due to the oats, but this adds to their charm.
5

Sandwich the cooled discs together with the jam.

Recipe FAQ

Can I use whole oats?
It's better to blitz them a little, as whole flakes make rolling and cutting the dough difficult.
