Try to cook the wieners and bacon by themselves at 400 degrees until the bacon is crisp. Then pour off most of the bacon grease. You’ll end up with about 3/4 cup fat! Then melt the butter and brown sugar in a microwave, mix well and spoon a tablespoon or so over each. You likely won’t use all of the butter/brown sugar mix unless you want to end up with candy. Bake at 400 until bubbling throughout, about 10 minutes. If you cook too long you will end up with toffee.
