Make the cups: Preheat the oven to 350 degrees F. Spray twelve 2 1/2-inch muffin cups with cooking spray; set aside.
Combine the meringue cookies and flour in a food processor; process until the mixture is in fine crumbs.
Add the melted butter and pulse until combined. Spoon about 2 tablespoons of the mixture into each of the prepared muffin cups. Using the back of a measuring tablespoon, press the mixture firmly into the bottoms and sides of the cups.
Bake for 8 to 10 minutes, or until just starting to brown.
Combine the pudding mix and sugar in a medium saucepan.
Whisk in the lemonade and egg yolks. Continue to whisk over medium-high heat until the mixture comes to a boil.
Remove from the heat and cool for 5 minutes. Spoon 2 tablespoons lemon filling into each cooled meringue cup. Top each with 1 tablespoon cherry pie filling. Chill for about 2 hours, or until the filling is set. If desired, top with whipped cream.
Serve the mini pies chilled or at room temperature.
