Preparing Strawberry Shortcake in a Jar is a delightful experience that involves simple steps. Follow these instructions:

1. Prepare Strawberries: In a bowl, combine sliced strawberries with granulated sugar. Let them sit for about 10 minutes to allow the juices to develop.

2. Make Whipped Cream: In a separate bowl, whisk together heavy whipping cream, powdered sugar, and vanilla extract. Beat until soft peaks form.

3. Prepare Jars: Gather mason jars or serving cups to assemble your dessert.

4. Layer Ingredients: Start by placing a layer of cake cubes at the bottom of each jar.

5. Add Strawberry Layer: Spoon a generous layer of the sugared strawberries over the cake cubes.

6. Add Whipped Cream: Top the strawberries with a layer of whipped cream.

7. Repeat Layers: Repeat the layering process, alternating between cake, strawberries, and whipped cream until jars are full, finishing with whipped cream on top.

8. Chill (Optional): For best results, chill the jars in the refrigerator for at least 30 minutes to let the flavors blend.

9. Garnish: Just before serving, add a few mint leaves on each jar for a pop of color.
