I remember seeing this cake a lot when I was growing up. I don't remember eating it much because, believe it or not, I didn't like cake all that much when I was younger.
Peach Butter Cake
1 yellow cake, baked and cooled in a 9 x 13" pan
1 block butter, softened
3/4 c sugar
1 egg
1 can (15.25 oz) sliced peaches
Pour peach slices into a mesh colander and drain 20 minutes. Using a spoon, mash peach slices against surface of colander until slices are broken up and smashed. Drain for 45 minutes, stirring and pressing peaches against colander periodically. Cream butter and sugar with an electric mixer for 5 minutes or until light and fluffy. Add in egg and beat until thoroughly incorporated. Stir in drained, mashed peaches. Frost top surface of prepared yellow cake. Cover and chill until ready to serve.
