Cook butter in small saucepan over medium-low until foamy and nutty light brown, 3 to 5 minutes. Scrape into a large bowl; stir in brown sugar, cinnamon, and salt. Stir in sweetened condensed milk and Peach Flavour.
In bowl, beat cream using an electric mixer starting on medium-low to medium-high until stiff peaks form. Fold in one-third into condensed milk mixture; fold in the remaining whipped cream until no streaks remain.
Spoon half of ice cream mixture into the loaf pan; sprinkle half of the cereal over the top. Repeat with the remaining ice cream and cereal; freeze for at least 6 hours.
Notes
Pro Tip:
Don’t have the cereal in your pantry? Swap it out for graham crackers to keep all that cinnamon-y goodness going!
