Drop in the chocolate toffee bites and be sure to fold with rubber/silicone spatula. IMPORTANT: Be sure to fold the bites and not stir because stirring will over mix. Add egg and vanilla extract, where at this point the mixture will have more of a smoother texture due to the egg’s yoke. Tip: Make sure your mixer is on low speed so that the mixture remains the right smooth texture (you don’t want dry).
