Here's a recipe I've used - I have another one but that cookbook is still packed somewhere! You can substitute any flavor cake mix and I have used chocolate chips. The main thing is filling the cones 2/3 to 3/4 full with batter.

Peanut butter party cones

18.25 or 18.5 oz package yellow cake mix
1 1/2 c peanut butter chips
1/2 c milk
24 FLAT BOTTOM ice cream cones
2 containers ready made frosting (I make my own)
decorations for cupcakes, your choice

prepare cake batter according to package directions. set aside.
melt peanut butter chips with milk in top of a double boiler over hot but not boiling water, stirring constantly until blended.
ad peanut butter mixture while warm to the cake batter
beat on medium speed until blended, about 2 min.
fill cones 2/3 to 3/4 full with batter
place upright in regular muffin cups or 2 inches apart on cookie sheet
bake 350 fro 30 to 35 min or until cake tester comes out clean
cool completely. frost, decorate

If you have to transport, the best way I have found is to use a 'shirt' type gift box, cut circles or X's in the top and insert the cones. Or you can put a large piece of posterboard over a cake pan and cut the circles. It just helps to have something to hold them up if you have to take them someplace.

If I find my other recipe, I'll post it, but who knows what box it could be in!! Hope that helps. Becky
