Line 9 x 13 baking dish with parchment allowing extra to be able to pull bars out of the pan easily to cut them on a cutting board.
Melt butter and pour into parchment lined pan.
Mix in “graham cracker” crumbs. Press into butter in pan.
Note: In remaining steps, when pouring ingredients over layers, be sure you do not skip the corners and outside rows. Bars will not hold together without all of that gooey goodness everywhere!
Pour half the condensed milk over the crumbs and then layer the remaining ingredients (except for other half of milk) evenly, pressing slightly after each addition. (Don’t press so much that remainder of milk will not drizzle down into the bars.)
Pour remaining sweetened condensed milk over all.
Bake for 25 minutes regular oven (20 minutes convection).
Cool. I like to cool mine in the fridge and cut when chilled so that bars hold together better. Do not cut until fully chilled as warm bars will not hold their shape.
