Notes
Drizzle: Try drizzling the cake with creamy caramel sauce or hot fudge sauce in an even layer. Or dust with cocoa powder.
Add Nuts: While not traditional, nuts add a great crunch, try pecans or walnuts.
Short cut tip: Make the cake in advance and decorate it fresh before the event so it can sit out at room temperature for a birthday cake for a party.
Variation tip: Instead of using crushed Twix chocolate bars, top each slice with a mini Twix candy bar.
Dietary consideration tip: Gluten free or low calorie versions of these products can be utilized.
Shortbread CrumbsTop: On top of the cake, use shortbread cookie crumbs to decorate.
