1. Preheat the oven to 180c and line a brownie or loaf tray with greaseproof paper (or grease with coconut oil)
  2. In a bowl, cream together the peanut butter and coconut sugar, then crack in the eggs one at a time, mixing thoroughly.
  3. Combine the dry ingredients, then fold these into the wet mixture. Pour your cake batter into your baking tray and pop this into the oven for around 16 minutes.
  4. Once your cake is cooked (it might still be slightly soft on top until cooled- that’s fine) allow cooling completely.
  5. Meanwhile, mix together the peanut butter, honey, and salt to create a smooth, creamy icing. Spread this generously on top of your sheet cake and slice into squares.
