This easy, from scratch blueberry peach cobbler is a delicious summer dessert!
If using fresh fruit: Gently stir the peaches, blueberries, and 1/4 cup of sugar together in a bowl and let the mixture sit for 30 minutes, stirring a couple of times.
If using frozen fruit: Combine the peaches and berries in a bowl and let sit for 20 to 30 minutes, until the fruit is partially thawed. Drain if the fruit has given off a lot of liquid, then return the fruit to the bowl. Stir in 1/4 cup of sugar and let sit another 10 or 20 minutes to allow the sugar to dissolve. (The fruit will give off more liquid but you don’t want to drain it at this point.)
