Reduce 1 sleeve graham crackers to crumbs. Layer 2/3 of the crumbs in a 1-quart jar. Place 8 marshmallow bunny peeps standing up, facing out around the inside of the jar. Press them up against the glass, but don't squash them. Carefully spoon remaining crumbs in the center of the jar to support the bunnies, pressing down to keep it snug. On top of this pour 1 1/4 cups Easter M&M's. Spoon 1/3 cup brown sugar into center of M&M's, gently pressing with a spoon.
Attach a gift tag as follows:
Easter Bunny S'Mores
Empty the jar contents into a bowl. Snip the bunnies into bits with kitchen sheers or cut up with a knife. Return the bunny bits to the mixture. Mix well.
Melt 1/2 cup butter; add 1 teaspoon vanilla extract. Pour this over the dry ingredients, mixing well. Pat into a greased 9-inch square pan. Bake at 350 degrees F for 15 minutes. Cool and cut into bars.
Makes 9 to 12 bars.
* Option - leave bunnies whole; combine remaining ingredients and place the bunnies on top; then bake as directed.
*This gift jar may be created to suit any holiday for which marshmallow candies are available.
