1 Tbs. cornstarch dissolved in 2 Tbs. soy milk or rice milk.
Crust: Preheat oven to 350 degrees. In medium bowl, mix cracker crumbs, syrup and extract until crumbs are moistened. Pour into oiled 9-inch pie plate; press mixture firmly to form crust. Bake 5 minutes; let cool while preparing the filling.
In food processor or blender, combine remaining ingredients and process until smooth, about 30 seconds. Pour mixture into crust. Bake until top is slightly browned, about 30 minutes. Cool and refrigerate until thoroughly chilled and firm, about 2 hours.
Preheat oven to 375 degrees F (190 degrees C). Lightly grease 10 muffin cups, or line with muffin papers.
In a large bowl, mix together 1 1/2 cups flour, baking soda, baking powder and salt. In another bowl, beat together bananas, sugar, egg and melted butter. Stir the banana mixture into the flour mixture just until moistened. Spoon batter into prepared muffin cups.
In a small bowl, mix together brown sugar, 2 tablespoons flour and cinnamon. Cut in 1 tablespoon butter until mixture resembles coarse cornmeal. Sprinkle topping over muffins.
Bake in preheated oven for 18 to 20 minutes, until a toothpick inserted into center of a muffin comes out clean.
