Healthy Frozen Berry Oat Slice

SERVES 24 | PREP 15 Mins | COOK 35 Mins

This healthy frozen berry oat slice is a winner. It was the first thing that went at the babes birthday and I had messages all week from friends asking for the recipe. It’s egg free and the best bit is you can tweak the ingredients to make it dairy and/or gluten free if you need. You could sub the flour for a mix of rice and buckwheat flours, change the oats to quinoa flakes and you could even sub the butter for coconut oil. I love making it with my babes and adapting whatever frozen berries I have on hand to mix up the flavour. It’s equally as good with fresh stone fruit and thinly sliced apples.

  • 250g butter, melted
  • 1 ½ cups whole oats
  • 1 ½ cups flour
  • ½ cup desiccated coconut
  • 2 tbsp chia seeds
  • 2 tsp vanilla bean powder, paste or essence
  • ⅓ cup sultanas
  • pinch of salt
  • ⅓ cup sugar (coconut, rice malt or maple)
  • 2 cups frozen berries


  • Step 1
  • Line a 25cm x 18cm oven tray with baking paper and pre-heat your oven to 200°C. Melt the butter in a saucepan whilst combining all the dry ingredients in a large bowl.
  • Step 2
  • Add the melted butter to the dry ingredients and stir/use your hands to combine. Make sure the mixture is holding together. If it isn’t, add a little more butter.
  • Step 3
  • Push ¾ of the mixture into the lined tray ensuring there are no holes left by pressing down very firmly. Roughly arrange the frozen berries over the mixture and sprinkle with the vanilla bean powder. Finish by sprinkling the remaining ¼ of oat mixture on top and bake for 35 minutes or until golden. Allow to cool in the pan before slicing.
  • Serving Suggestion
  • Served from the fridge is great. Not only is this slice delicious cold, it tends to hold together better too.

Stacey Clare's Nutritional Tip

  • Frozen berries are a great economical option when eating berries. When you can, buy the organic variety because berries don’t have a ‘peel’ (protective layer) so they tend to soak up a lot of the pesticides when sprayed in conventional farming methods. I buy organic ones in a white packet from the freezer section of either Woolworths or Coles.
