Note
Use Quality Chocolate: Since chocolate is the main ingredient, using good-quality chocolate will enhance the flavour and texture of the cake. Dark, milk, or a mix of both works well.
Biscuit Choice Matters: Gluten-free digestive biscuits work best for an authentic taste, but you can also use gluten-free shortbread or rich tea biscuits for variation.
Customise the Add-Ins: Feel free to add chopped nuts, dried fruit, mini marshmallows, or even gluten-free pretzels for extra crunch and flavour.
Melt Chocolate Gently: To avoid burning, melt the chocolate slowly using a double boiler or microwave in short 30-second bursts, stirring in between.
Make It Dairy-Free: Use dairy-free chocolate and dairy-free butter to make this cake suitable for those avoiding dairy.
