Pro tip
Add the butter, brown sugar, and salt to a saucepan over medium heat. Stir in the oats and vanilla and toast the oats, about 2 to 3 minutes. Press half of the oat mixture into the bottom of a loaf pan.
Melt the white chocolate chips and peanut butter together, and spread it out evenly on top of the oat mixture in the loaf pan.
Sprinkle the remaining oat mixture on top and refrigerate until set. Cut into bars, and then drizzle the melted semi-sweet chocolate on top. Sprinkle on the flaky sea salt.
