Deliciously thick and chewy peanut butter cookies that are full of flavour, and have hidden jam centres. These are the PERFECT cookies for PB&J lovers!
Preheat the oven to 180C/350F/Gas 4. Line a baking tray with parchment paper or a silicone mat, and set aside.
Whisk together the flour, baking powder, baking soda, cornflour, and salt. Set aside.
In a separate large bowl, whisk together the melted butter and sugars until combined.
Add the egg, vanilla, and peanut butter, and mix until combined.
Add the dry ingredients, and mix until just combined - do not overmix.
Roll the dough into 2oz balls. Form the balls into flat circles, and place 1 teaspoon of jam into the centres. Form the dough back into balls, sealing the jam inside.
Place onto the prepared baking tray and bake for 12 - 14 minutes.
Allow to cool on the baking tray for 10 minutes before transferring them to a wire rack to cool completely.
