This decadent fudge combines the creamy sweetness of condensed milk with the tangy zest of lemon curd and the airy lightness of marshmallows, all finished with a crunchy biscuit topping. A perfect treat for any occasion!
For a more intense lemon flavor, add the zest of one lemon to the fudge mixture. You can also substitute milk chocolate chips for the white chocolate chips, or use a combination of both. If you don’t have digestive biscuits, graham crackers or even crushed shortbread cookies work well as a substitute. Allow the fudge to sit at room temperature for a few minutes before slicing for easier cutting.
