As we prepare to welcome Mary Berry, Queen of Cakes, to unveil our new state-of-the-art store at Teesside Retail Park on Saturday March 28, we’re asking our customers to reveal the one question they’ve always wanted to ask Britain’s baking legend.

The TV star will be participating in a series of Q&As with customers so we wanted to give our fans and followers the chance to grab a slice of the action.

We’re asking you to share the question you’d most like to #AskMary for the chance to win a signed copy of her much adored book; Mary Berry’s Baking Bible.

We’ll be selecting four winners, from all entries submitted, whose questions will be put to Mary on the day – we’ll reveal her answer for all of our fans and followers to hear and then send your hand-signed book on its way.

To enter, simply submit your question in the comments box below, or share it with us on Facebook, Twitter or Instagram using #Ask Mary
