Peel the peaches and slice into thick wedges. Place the peaches in a large bowl. Add the blueberries, lemon zest, lemon juice, granulated sugar and flour.
Gently toss everything together. Allow the fruit mixture to sit for 5 minutes.
For the crumble, combine flour, granulated sugar, brown sugar, salt, cinnamon, and diced cold butter. You can use an electric mixer with a paddle attachment, a food processor or a pastry cutter to mix it. Mix until the butter is the size of peas.
Spoon the fruit mixture in to ramekins. Sprinkle the crumble evenly over the top.
Place the ramekins on a sheet pan lined with parchment paper and bake for 40-45 minutes, until the tops are golden brown and the juices are bubbly.
Serve warm or at room temperature with some good vanilla ice cream. Enjoy!
