Preheat oven to 375°F (190°C). Butter two 5-inch pie plates.
Place apples and pears in a medium bowl. Add sugar and toss to coat. Set aside.
Combine crushed cookies and butter until well-mixed.
Stir fruit and sugar again. Transfer to prepared pie plates, dividing evenly. Pour juices in the bowl over the fruit.
Sprinkle the cookie mixture over the fruit.
Place the pie plates on a baking sheet. Loosely cover the entire pan with aluminum foil.
Bake 35-40 minutes, or until the topping is deep brown and the fruit is bubbling.
Remove pan to a wire rack to cool before serving. Serve warm or at room temperature.
Notes
*The cookies don't have to be finely ground, but I liked them that way. I ground them quickly and easily in my mini food processor. You can also break up the cookies and place them in a sealable plastic bag, and crush them by rolling a rolling pin over them.
To make this crisp in an 8-inch round pan, simply double the recipe.
