Oat-my-goodness slice

Sometimes there’s just nothing like a good old fashioned slice with a cup of tea. This crumbly oaty slice is a winner with just sultanas, just chocolate, or a combo, depending on your mood! 

This recipe just reminds us of something our nannas would’ve baked, and there’s absolutely no better recipe worth sharing.

And the best bit is that it’s VERY easy. The hardest part is melting the butter, and then you simply just mix it all together. 

A quick bake and it’s ready to go. Serve while it’s crumbly and warm or cool and eat when the mood arises.

Oat-my-goodness slice recipe

Prep Time 10 minutes
Cook Time 20 minutes


In your kitchen

  • 150 g butter
  • 2 free range eggs

In your Hey Baker box

  • 1 cup plain flour
  • 2 tsp baking powder
  • 1 cup oats
  • ½ cup brown sugar
  • cup sultanas optional
  • ½ cup chocolate chips optional


  • Preheat oven to 180°C. Line a 20cm square cake or slice tin with baking paper.
  • Melt the butter in the microwave until runny, but not too hot (allow to cool if needed). Lightly whisk eggs in another bowl.
  • Mix butter, eggs, flour, baking powder, oats, brown sugar, and vanilla together in a large bowl.
  • Add sultanas and/or choc chips and stir through. The mix will be quite thick.
  • Transfer to lined tin, flatten and push mix to sides with a spoon or spatula.
  • Bake for 20 minutes or until golden on top. Allow to cool slightly in tin before transferring to a board to cut into squares.


Psst... make it your own

Add other dried fruit (like apricot or apple) to the slice to mix it up a bit. Or instead of adding the choc chips, melt them and drizzle over the top once cooked (add 2 tbsp butter to thin the mix down if needed).

Did you know the early Greeks and Romans used to adorn places of worship with sultanas, and used to give them out as prizes at sporting events? Not bad for a shrivelled up grape!
