Expert Tips

  • Forming The Base: When pressing the cornflake base mixture into the pan, use the back of a spoon or your hands to ensure the layer is even and compact. This helps the slice bake uniformly and makes slicing easier after it sets.
  • Cooling the Base: Allow the base to cool for 20 minutes before applying the icing. This prevents the icing from sinking into the warm base but allowing the base to still be slightly warm for the icing to spread over the top.
  • Sifting the Icing Sugar: Always sift your icing sugar before mixing to avoid lumps in your icing. This creates a smoother finish.

Is it normal for the slice to be soft and bubbly when removed from the oven?

Yes, it is normal for the slice to appear soft and bubbly right after baking. It will continue to firm up and set as it cools down, achieving the desired consistency once fully cooled. Be sure not to remove it from the pan until it’s completely cold and set after being in the refrigerator.

Instructions
 

Base

  • Preheat Oven: Preheat the oven to 180ºC (356ºF) and line a 9” x 9” square tin with parchment paper. Set aside.
  • Mix Base Ingredients: In a mixing bowl, combine cornflakes, almond meal, coconut sugar, and baking powder. Mix until combined. Set aside.
  • Melt Coconut Oil and Honey: In a small saucepan, gently heat the coconut oil and honey over low heat until the oil is completely melted.
  • Combine Wet and Dry Ingredients: Pour the melted coconut oil and honey into the bowl of dry ingredients. Mix with a wooden spoon until everything is well combined.
  • Press into Pan: Transfer the mixture to the lined pan, pressing down firmly to form an even layer, use your hands or silicone spatula.
  • Bake: Place in the oven and bake for 12-15 minutes until the edges are browned and the center is golden. It will still be soft and bubbly when removed from the oven, it will firm up as it cools.
  • Cool Base: Allow the baked base to cool in the pan for 20 minutes.

Icing

  • Prepare Icing: When the base has about few minutes remaining to cool, start making the icing. In a small mixing bowl, sift the icing sugar. Pour in the melted butter and water. Whisk until smooth and thick.
  • Apply Icing: After the base has cooled for 20 minutes in the pan, pour the icing over the still-warm base, while it’s still in the pan. Move the pan around to help spread the icing evenly across the surface or use a spatula.
  • Chill to Set: Place the pan in the refrigerator and chill for 1-2 hours or until the icing and base is firm and has set.
