I don't know if this will help much since my recipe doesn't include butter. I'm sure you could incorporate butter into the recipe so here goes.
5 pounds of chicken wings - separate and discard tips.
Lemon pepper of your choice
Garlic powder - optional
Pre-heat oven to 500 degrees - broiler prefered. Rinse cut wings thoroughly and place in large strainer or collander to drain. Prepare a large shallow baking pan by lining with aluminum foil or spraying with a product such as Pam. Place a grill type rack such as a cake cooling rack in the pan. Place as many racks as needed to cover the pan. Pour a liberal amount of lemon pepper along with one teaspoon of garlic powder (optional) into a large zip lock bag. Place wings in bag, seal and shake until wings are well coated. Place coated wings on rack(s) inside baking pan. You can place the wings as close together as desired but for crispier wings you will want to leave space between wings. Place in oven for 20 minutes, turn wings over and place back in oven for another 10 to 15 minutes. I usually use this method when making oven baked BBQ wings. My final step for this is to remove the cooked wings from the oven, place them in a large casserole dish, pour my favorite BBQ sauce over them, stir until all wings are coated and place the dish back in the oven at 400 degrees for another 20 minutes changing the oven from broil to bake.
I'm sure you could coat the wings in melted butter or margarine before you place them in the bag with the lemon pepper and garlic powder to acheive a different taste. You may have to really watch them to see that they don't scortch in the oven. Experiment with chicken wings. As long as you don't get too crazy how can you go wrong?
