Twenty odd years ago I used to "tut, tut" some recipes that used to use pre mixes, probably because we don't/didn't have them here in Scotland. Things are improving, but we'll never have the advantages that the American people have. I did discover Wrights here in the UK who have a lot of pre-mixed cakes, breads etc and have tried them with my own tweaks. i.e. their Ginger Loaf is good, but especially good when adding Mango Pulp, an egg and sometimes some pecan nuts. You do need to experiment. I found this recipe recently, sorry can't give credit as for some reason I missed that out. Still to try once my order arrives from Wrights. Let me know if you get around to trying it?.
Pre-heat oven to 350 degrees. In a large mixing bowl, combine the cake mix, 1 egg, butter, and pecans. Mix well. Press into a greased 9x13 pan. In the bowl of a stand mixer, beat together the cream cheese, 2 remaining eggs, and the powdered sugar until well combined. Pour over the crust. Bake for 45-50 minutes or until the top is golden brown and the center is set. It should be gooey, but not runny. Cool completely before cutting, 1-2 hours. Store in the refrigerator.
I want to encourage youngsters (male or female) to get into the kitchen and enjoy cooking. TASTE it!
