Whip cream in chilled bowl (see Notes) until stiff peaks form

To layer, place half of a lady finger at the bottom of the shooter glass. Top with a small spoonful of berry whipped cream, 2-3 raspberries, and a sprinkle of graham cracker crumbs. Place a lady finger half on top and continue layering with cream and berries.
Notes
Chill a metal bowl plus metal beaters from mixer in a freezer 15 minutes up to overnight before beating cream to help with whipping process.
