Preheat oven: 180°C / 160°C (fan) / Gas Mark 4 / 350°F
Melt the butter for 30-50secs in the microwave and beat in the sugar until smooth and thick.
Thoroughly beat in the egg, orange and vanilla extracts until well combined.
Sieve in the flour, cornflour and salt, stirring until just combined.
In a lined 8inch square pan, pour half of the blondie mix smoothing evenly, before breaking up the mince pies into 5-7 pieces each and spacing these evenly across the mix.
Pour the remaining blondie mix over the top, smoothing gently to cover the mince pie pieces.
Bake in the oven for 20-25mins, until the top is lightly golden and no longer wobbles. Allow your blondies to cool before removing from the tin and cutting into squares.
