Looking for a delicious treat that the kids can help make and bake? These blueberry crumb bars are exactly what you’re looking for! The kids can get involved in the weighing and mixing process, and of course, they have to be the best taste testers too.

Don’t miss the chance to have your say! We’re looking for parents to get involved and give their feedback on all aspects of family life. Find out more here.

This delightful blueberry recipe has been adapted from Smitten Kitchen. The crumb bars are delicious for a quick and light breakfast but are also a lovely extra in lunchboxes. If your household isn’t blueberry fans, this recipe works with other fruits too.

If you are lucky to have a food processor to hand, the dough is even easier and quicker to pull together. This recipe will make about 36 small rectangles, so you’ll have plenty to go around.

These Blueberry Crumb Bars Are Super Scrummy


  • 300g / 10.5oz caster sugar
  • 425g / 15oz all-purpose flour
  • 1 tsp baking powder
  • 1/4 tsp salt
  • Zest and juice of 1 lemon
  • 225g / 8oz cold butter, diced
  • 1 egg, lightly beaten
  • 4 tsp cornflour
  • 600g / 21oz fresh blueberries


  1. Preheat the oven to 190°C / 375°F. Grease a 9×13-inch pan.
  2. In a medium bowl, stir together 2/3 of the sugar with the flour and baking powder.
  3. Mix in the salt and lemon zest. Use a fork or pastry cutter to blend in the butter and egg. The dough will be crumbly. (Alternatively, briefly whizz the sugar, flour, baking powder, salt and lemon zest in a food processor to just combine.)
  4. Add the butter and egg. Blend until a crumbly dough is formed. Pat half of the dough into the prepared pan.
  5. In another bowl, stir together the remaining sugar, cornflour and lemon juice. Gently mix in the blueberries. Sprinkle the blueberry mixture evenly over the crust. Crumble the remaining dough over the berry layer.
  6. Bake for 45 minutes, or until the top is slightly brown.
  7. Cool completely before cutting into squares (they will cut even easier if you chill them in the fridge), though cutting just a few crumbly ones still warm from the oven will do no harm to the rest of the pan.
