Ingredient Notes & Details
Unsalted butter
Use high-quality butter for a rich, creamy base. Can substitute with margarine if dairy-free, though flavor may be slightly different.
Brown sugar
Provides deep caramel notes and chewiness. Light or dark brown sugar works, but dark sugar will give a more intense flavor.
Cocoa powder
Choose unsweetened cocoa powder. Dutch-processed works well for a smoother taste and darker color.
Rolled oats
Adds texture and chew. For a gluten-free version, use certified gluten-free oats.
Desiccated coconut
Provides a subtle tropical flavor. You can toast lightly for added depth or replace half with chopped nuts for crunch.
Plain flour
Keeps the base tender yet firm. Can substitute with gluten-free flour blend for dietary needs.
Sweetened condensed milk
Essential for richness and sweetness. Makes the slice chewy and decadent.
Chocolate icing
A simple mixture of cocoa, icing sugar, and butter creates the glossy topping. You can enhance it with a splash of vanilla extract.
Step-by-Step Instructions
Prepare your baking tray
Line a 20cm x 30cm tray with baking paper. This prevents sticking and makes slicing easier.
Mix the dry ingredients
In a large bowl, combine rolled oats, desiccated coconut, cocoa powder, and flour. Stir well to evenly distribute the ingredients.
Melt butter and sugar
In a saucepan over low heat, melt unsalted butter with brown sugar. Stir constantly until the sugar dissolves and the mixture is smooth and glossy.
Combine wet and dry ingredients
Pour the melted butter and sugar over the dry ingredients. Add sweetened condensed milk and mix until a thick, sticky dough forms. The texture should be firm but pliable.
Press into tray
Transfer mixture to the prepared tray. Use a spatula or your hands to press evenly into the base. The thickness should be about 2cm for the perfect chew.
Make chocolate icing
In a small saucepan, melt butter with cocoa powder and icing sugar. Stir until smooth, glossy, and slightly pourable. Allow to cool slightly before spreading.
Spread icing over base
Pour the chocolate icing evenly over the slice. Use a spatula to smooth the surface. Sprinkle extra desiccated coconut on top if desired.
Chill and set
Refrigerate for at least 2 hours or until firm. Cut into squares or rectangles before serving.
