Preheat oven to 350 degrees F.
Cut peaches in half and remove the pit. Slice each half into 4-5 slices. Toss peach slices with olive oil, honey, and cinnamon. Spread in an evenly layer in a baking dish and roast for 10 minutes. Cover the pan with aluminum foil and continue to bake for 25 minutes or until the peaches are tender. Remove from heat.
Remove half of the peaches and puree until smooth. Reserve the remaining roasted peach slices and let cool completely.
Line a 10x10" baking dish with parchment paper long enough to hang off the sides.
In a food processor, pulse 30 Golden Oreo cookies into a fine crumb. Add 4 ½ tablespoons (63 grams) melted butter and mix until combined. Transfer crumb mixture into the prepared baking pan and press down into one even layer to create the crust. Chill in the freezer for 1 hour or until set.
Whip heavy cream in the bowl of a stand mixer until stiff peaks form. Add sweetened condensed milk, vanilla extract, salt, and peach puree, gently stirring until combined. Fold in the reserved roasted peach slices and pour ice cream into prepared pan. Use a spatula to smooth the top and chill in the freezer for 1 hour.
Combine remaining 15 Golden Oreos and freeze-dried peaches in a food processor. Pulse until they become fine crumbs. Add remaining 4 ½ tablespoons melted butter ( 63 grams) and mix until combined.
Sprinkle crumb topping on top of ice cream in an even layer. Return ice cream to the freezer for at least 4 hours or overnight. Slice and serve.
