Using a hand-mixer or stand-up mixer with the whisk attachment, on medium speed, blend together the mascarpone cheese, ½ of the sugar until light and fluffy.
Add the amaretto at this point if you choose to use it.
Scoop this mixture into another bowl and set it aside.
In a mixing bowl, add the heavy whipping cream and the remaining sugar. Blend on high speed just until stiff peaks form, for about a minute or two.
Turn off the mixer and carefully fold the whipped cream into the mascarpone mixture that you had set aside.
Using clear glasses or goblets, begin to layer the parfaits with cubes of bread/cake for the first bottom layer.
Spoon on a layer of the mascarpone cream mixture.
Place a layer of sliced peaches on top of the cream.
Continue layering until 2 or 3 layers are completed.
Garnish with an Italian amaretti cookie, a sprig of mint, and a raspberry.
ENJOY! Buon Appetito!
