💭Tips for Recipe Success
Melt Chocolate Carefully: When melting chocolate, use a gentle heat method such as a double boiler or microwave in short bursts, stirring in between. Avoid overheating, as it can cause the chocolate to become grainy.
Uniform Cookie Size: Try to use cookies that are roughly the same size to ensure an even distribution of the ingredients and a consistent texture in the final cake.
Layering and Pressing: When layering the biscuits in the pan, press them down slightly to create a compact structure. This helps the cake hold its shape when sliced.
