Instructions

Preheat oven to 350°F (176°C). Line a 9x13-inch pan with parchment paper, leaving some overhang for easy bar removal. Don’t line the pan with wax paper or foil. Melt the butter in the microwave and set aside to cool back to room temperature—using hot butter makes the crust greasy.
Coarsely break up graham crackers and add to a powerful blender (you may need to do this in batches). Pulse/blend until all crackers are fine crumbs. Measure a level 2 and 1/2 cups (288g) of the crumbs and add to a large bowl, along with the salt. Stir in the melted but cooled butter and mix to create a thick mixture. Press this mixture into the prepared pan and use the bottom of a flat measuring cup to firmly press the crust into an even layer.
Pour the can of sweetened condensed milk over the graham cracker crust. Spread it into an even layer with the back of a spoon. Evenly top the condensed milk with quick oats, chocolate chips, butterscotch chips, white chocolate chips, and M&M’s. Gently press everything into an even layer.
Bake in preheated oven until the edges are golden brown, about 23–28 minutes. My oven is done right at 25 minutes.
Remove from oven and allow bars to cool completely, about 1–2 hours. Speed up the cooling process by putting them in the fridge after they’ve cooled for about 20 minutes at room temperature. Use the parchment overhang to remove the bars, and use a sharp knife to make decisive cuts. Run the knife under warm water, dry on a kitchen towel, and repeat for each cut.

Notes

Note 1: It’s easy to pick evaporated milk or a similar product by mistake, but only sweetened condensed milk works in this recipe. Be sure to get the full-fat variety and avoid sugar-free. I use and love Eagle Brand® (not sponsored).

Note 2: I love the richness and sweetness of milk chocolate, but any type of chocolate works, such as dark or semi-sweet chocolate (for less sweetness).

Note 3: Any color M&M’s work, but for a spring-focused treat, use Easter or pastel colors. I don’t recommend peanut, peanut butter, or larger M&M’s because they don’t hold in the bars as nicely.

Storage: Store leftovers in an airtight container separated by layers of parchment or wax paper. Store in the fridge if the temperature is warm or on the counter for cooler temperatures. (There is nothing about these bars that requires refrigeration, but if you prefer them to be less gooey and more firm, store them in the fridge.) Best enjoyed within 3–5 days.
