In a stand mixer fitted with the whisk attachment, add the heavy cream and sugar. Beat on medium speed for about 1 minute or until stiff peaks form. Set aside.
Slice the pound cake and strawberries to your desired size and shape.
Begin with a layer of pound cake at the bottom of your mason jar. The amount of cake will depend on your jar size and how many layers you want.
Spoon a generous layer of whipped cream over the pound cake. Use a spoon or, for cleaner lines, a piping bag.
Add a layer of sliced strawberries, arranging them nicely for visual appeal.
Continue alternating layers of pound cake, whipped cream, and strawberries until you are about ½ inch from the top of the jar.
Top with a final layer of whipped cream.
Add a whole strawberry to the top of each jar for a beautiful finishing touch. Serve immediately, or store in the refrigerator for later.
Notes
Store your mason jar dessert in the refrigerator with the lid tightly sealed to maintain freshness. The whipped cream and strawberries make it perishable, so refrigerate it immediately and enjoy within 2-3 days for the best taste and texture.
