Birthday boy slice

For me, one of the greatest things about starting Mabel & Joy is having an abundance of organic ingredients at my disposal, ready for me to have my way with them. When inspiration strikes, I can literally go straight to the kitchen and whip something delicious up (or at least I hope it is delicious), in my gigantic size bowl, with my gigantic sized muesli muscles. Ok they are not gigantic, it only feels like I’ve been lifting 50kgs after stirring 20kgs of muesli on the daily. Ouch.

James, my husband and partner in this mad muesli caper is my chief tasting officer, especially now that gluten and I have become arch-enemies. Luckily, he’s just so damn good at it, and so I have given him a promotion where now he is testing all sorts of creations to be added to our product range.  

Not so long ago, I cooked a few desserts for James’ birthday (that they got removed from the venue we were at because I bought outside food in, is another story). I wanted to cater for sweet-toothed hunger monsters, but also to those who watched what they ate, and were not so keen on the crack we call sugar.

I combined James’ favourite flavours – chocolate and peanut butter – to make a pretty yummy slice. Whilst definitely not sugar-free, this slice is not full of rubbish and can be seen as a sporadic treat. I hope you enjoy, and if you make it, let us know what you think in the comments or tag your pictures with @MabelandJoy.

Birthday Slice

Birthday boy slice


3 cups of PB&C Toasted Muesli or

3 cups rolled oats, 2 cups pure peanut butter, ¼ cup cacao nibs, 2 tbls cacao

3 tbls brown rice syrup

1 tbs chia seeds

1 tbs linseed (flaxseed)

1 tsp ground cinnamon

20g butter

200g dark chocolate



  1. In a saucepan, warm the peanut butter and brown rice syrup together. Do not allow to boil, as you do not want the mix to burn.
  2. In a large bowl, mix the remaining ingredients together (except the butter and dark chocolate) and pour the liquid mix over it. Using a large spoon (or your clean hands), stir until the mixture is well blended.
  3. Pour the mix into a greased and lined pan and press with your fingers.
  4. Place a clean bowl over a small saucepan with about an inch of simmering water. In the bowl, melt the chocolate with the butter, and pour over the slice.
  5. Place the slice in the fridge and allow to set, before cutting into desired shapes. If you can’t wait, pop it in the freezer.
