Raspberry Crumble Bars

These dessert squares with raspberries and oat crumble are sweet, tangy and totally delicious. Raspberries, oats, brown sugar, butter, flour and more

I need to make a confession. I look for any opportunity to make oat crumble. The combination of oats, brown sugar and butter – they all work together to make something sweet, crunchy, and totally delicious.

So, after I picked a bunch of raspberries at Millar Berry Farms, I knew that I was going to make some sort of raspberry crumble. These are quite similar to the way that I make apple crisp, but, the middle is with raspberries instead of apples.

Mixing the fresh berries with a little flour and sugar turn the middle into something similar to a fruit pie filling.

These crumble bars have a wonderful combination of sweet and tang. Once made, they can be cut and then frozen for a couple months. That is a great way to store them if they do not all get eaten right away. They are that good!

  • Lovely results, went straight in my favourites. I did tinker, adding 1tsp cinnamon and of vanilla essence to the topping and cutting the sugar down by a third, replacing plain with self raising as I can’t eat baking powder. Filling half blackberries as that’s what I had, omitted lemon juice and used used potato flour to thicken with again a third less sugar. Needed 45 mins to get a good colour in my oven.
