DIRECTIONS
1. Heat oven to 350°F. Grease a 2-1/2-qt ovenproof glass bowl and two 8-in. round cake pans; line bottom of pans with wax paper.
2. Prepare both cake mixes in one bowl as pkg directs. Divide batter evenly between prepared bowl and pans. Bake bowl 35 to 40 minutes, pans 25 to 30 minutes until cakes are golden brown and a wooden pick inserted in centers comes out clean. Cool in bowl and pans on wire racks 15 minutes. Invert on racks; cool completely.
3. Tomato slices: Put-2/3 cup vanilla frosting in a 1-cup glass measure; tint red with food color. Place round cookies on wire rack over wax paper. Microwave red frosting 5 seconds or until texture of slightly whipped cream. Pour over cookies, coating evenly. Let dry at least 30 minutes.
4. Cheese: Microwave orange Air Heads 2 to 5 seconds to soften slightly. Place side by side on plastic wrap, overlapping slightly. Roll out to a 9-in. rectangle. Cover with wrap until assembly.
5. Lettuce: Microwave green chews 2 to 5 seconds to soften slightly. Place each piece on plastic wrap; roll out to a 3-in. strip. Trim one edge with pinking shears to look ruffled. Cover with wrap until assembly.
6. Onion rings: Press 2 white spice drops together. Sprinkle work surface with some of the sugar. Roll out drops to a scant 1/4 in. thick. Using cookie cutters, cut out onion rings.
7.Olive: Fold Fruit by the Foot in half lengthwise. Cut slits 1/8 in. apart for tassel. Wrap around end of a 2-in. piece of pretzel. Trim slice from bottom of green gumdrops; press cut ends together. Cut LifeSaver in half; press into end of olive for pimiento. Insert whole pretzel into olive; press pretzel with tassel into other end.
8. Eyes: Use a dot of vanilla frosting to glue M&M’s on each marshmallow half.
9. To assemble: Tint remaining vanilla frosting with brown food color until shade of lightly toasted bun. Trim cakes to level tops. Place 1 layer on serving platter; coat top and sides with bun frosting. Arrange lettuce on top, overlapping and pinching candies together for a ruffled look.
10. Place other cake layer on wax paper. Coat top and sides with milk chocolate frosting; press on crushed cookies. With broad spatula, place on lettuce on bun. Top burger with the cheese, hanging over slightly, then the tomato and onion rings.
11. Place the bowl cake, cut side down, on wax paper; frost with rest of bun frosting. Place on top of burger. "Glue" eyes on with icing. Press pine nut "sesame seeds" on top of bun; insert olive.

Layer the cake, fruit, and a little less than half of the pudding mixture in a loaf pan. Then top the cake with the remaining pudding. 
Bake the crust:Heat the oven to 450°. Unroll or unfold a piecrust on your work surface. Using the upside-down potpie tin as a guide, cut a circle of dough about 1/2 inch larger than the tin. (If you're making more than one potpie, simply cut another circle from the dough. Reroll the scraps to cut out a third.) Crumple a piece of aluminum foil into a 1 1/2-inch ball and set it in the potpie tin. Cover it with a layer of foil to create a smooth mound, then lay the circle of dough on top. (A) 
Now press the tines of a fork around the edge of the dough to crimp it, then use the fork to gently poke a few holes in the crust. (B) 
Corn kernels: Roll the yellow candy between your hands or on a clean work surface to create a 4-inch-long rope, then use kitchen shears or a sharp knife to cut the rope into 1/4-inch pieces. With your fingers, form each piece into a kernel by flattening one end and pinching the other. 
Chicken: Use kitchen shears or a knife to cut the apple rings into 1/2-inch-wide pieces. If you're using white chocolate, chop or break it into roughly 1/2-inch-wide pieces. 
Peas: Roll the green candy into a 5-inch-long rope. Cut the rope into 1/4-inch pieces, then roll each piece into a ball.
