Shortbread Jam Squares Recipe

Preheat the oven to 350 degrees F.

In a bowl, whisk together the butter and caster sugar until combined.

Whisk in the egg, oil, and vanilla extract.

Mix in the baking powder and 2 cups of the flour with a spoon, until combined.

Bring the mixture together using your hands to make a dough.

Spray a 9-inch square baking tray with cooking oil. Spread out half of the dough on the tray.

Prick the dough with a fork to prevent bubbles from forming while baking.

Spread the blackcurrant jam on top.

With the remaining dough, mix in the remaining flour and rub with your fingers to make a crumb-like texture.

Sprinkle the crumbs on top of the jam.

Bake for 20 minutes, until golden brown on top.

Leave to cool for around 20 minutes as the jam will be hot.

Sieve icing sugar on top.

Cut into squares.

Enjoy!
