Berry Oat Crumble Bars

While in lockdown I’ve tried out a few different baking recipes, although still not a banana bread surprisingly. Out of all the recipes I’ve tried this has been the easiest and one of the tastiest bakes. Quite a few people have got in touch asking for this recipe so I thought I’d share.

Let me know if you try it and share you photos with me, I love seeing people try the recipes I post.

For the filling

  • 350 g Frozen raspberries (or berries of your choice)
  • 50 g Caster sugar
  • 1 tbsp Plain flour
  • 1 tbsp Cornflour

For the crumble

  • 135 g Porridge oats
  • 180 g Plain flour
  • 150 g light brown soft sugar
  • 1 tsp baking powder
  • 140 g salted butter (melted)


  • Preheat the oven to 200°C/180°C fan and line a 20" square baking tin.
  • Place your berries into a colander and run under a warm tap for a minute and leave to drain for around 30minutes until softened. Squeeze out as much excess water as you can.
  • Mix the berries in a bowl with the caster sugar, cornflour and plain flour.
  • In a separate bowl take the oats, flour, brown sugar, baking powder, melted butter and mix until it comes together in a crumble-like mixture.
  • Firmly press around two thirds of the crumble in to the prepared tin, making sure to cover the entire base. Bake fo 10 minutes.
  • Remove from the oven and carefully arrange the berry layer on top of the bottom layer.
  • Sprinkle the remaining crumble mix over the top and bake for a further 10 minutes until turning golden.
  • Remove from the oven and leave to cool. Once cooled, chill in the fridge for around two hours and then cut into bars.
  • Put the kettle on and enjoy 🙂
