"Makes easy and delicious raspberry chocolate bars"

chocolate raspberry slice

My Chocolate raspberry slice is a variation of my delicious rich and moist easy chocolate cake receipe. It's just another way of using this versatile recipe.

Some of you may be used to calling this recipe chocolate raspberry bars, but to me they are the same the only difference is where we live in the world.

I suggest that you chill the cooled slice first this will make it easier to slice.

Sometimes I just dust the top of the raspberry chocolate slice with icing sugar (confectioners sugar) other times I spread a layer of my chocolate glaze recipe over the top.

Please read through my chocolate raspberry slice recipe first before starting.

Chocolate Raspberry Slice Recipe

Makes a 20cm x 30cm slice pan

Spray a 20cm x 30cm slice baking pan with non-stick baking spray. Line the base with non-stick baking paper. This is important as this slice will stick to the pan if you do not take this step.

The raspberry chocolate slice can be sliced into as many portions as you need.


raspberry chocolate slice

250g butter, chopped
1 1/2 cup (375ml) water
1 cup (220g) caster sugar
1/3 cup (35g) cocoa powder
2/3 cup (100g) dark chocolate, chopped
1 2/3 cups (250g) plain flour, sifted
1 teaspoon bi-carbonate of soda (bi-carb soda)
2 cups frozen raspberries

I use frozen raspberries as they are easier to handle and I always have them on stand-by in the freezer. Fresh raspberries can of course be used.

Baking Temperature

The oven should be preheated to 160C (325F)


  1. Combine the butter, water, sugar, cocoa powder and chocolate together in a medium sized saucepan.
  2. Place over gentle heat. Bring to the boil whilst stirring. You need to stir until everything has dissolved to stop the mix from burning. Be careful that the mix does not boil over.
  3. Simmer gently for 5 minutes.
  4. Remove from the heat. Cover with a lid and leave to cool to room temperature. To cool this quickly place the saucepan in a sink of cold water and stir.
  5. Whisk in gently the flour and bi-carb soda into the cooled liquid. Whisk until all lumps are removed. Do not over whisk; you are not trying to add air into the batter just remove any flour lumps.
  6. Carefully fold through the raspberries.
  7. Pour batter into the prepared slice pan. Remember the baking pan must be lined with non-stick baking paper. The batter will be quite liquid and will level naturally.

    The thing to remember is that the frozen rasberries may stiffen the batter so you may need to spread the batter. Tap the tin on the kitchen bench three times to remove any large air bubbles.

  8. Bake in a preheated oven set at 160oC (325oF) for 45 mins. It may take alittle longer because the frozen berries chills the batter.
  9. Remove from the oven. Leave to cool in the tin.
  10. If you are going to top with my chocolate glaze recipe then the slice should be cooled first. Half the glaze recipe quantity should be enough. The rest can be stored for two weeks in the fridge. You could use it served warm as a sauce and make this slice a dessert - just add some fresh raspberries for presentation.
  11. This slice will keep one week if kept in an airtight container in the fridge.
