Use them in bread or cakes
You can still use your oven if you prefer other baked items than those that are poured with a thick, delicious filling. Try including leftover peaches in sweet bread or even cake instead of making pie. To make a welcome break from coffee cake with your morning cup of tea, the peaches can lend a delicious flavor to your favorite sweet bread (via MyRecipes). Peaches could be substituted for strawberries for those who prefer fruity desserts like strawberry cake.
It's easy to add peaches to bread. Simply cut it into bite-sized pieces and distribute them throughout the dough. If you'd like, you can easily slice them up and add them to the cake mix or even frosting to enhance the cake. To keep the fruit pieces properly distributed throughout the bread or cake, you must toss them in flour for a thin coating before adding them to the dough or batter.
