I’m sharing the best magic bar recipe you’ll ever use: magic bars but with oatmeal cookie crust! It’s a multilayer dessert dream.

Why you’ll love this recipe

  • Don’t you love a recipe where you can easily customize it to your taste buds? You have options in this recipe!
  • These freeze well and are absolutely delicious

Ingredients in 7 layer bars

  • Butter- softened and unsalted work best for this recipe
  • Sugar- you’ll want to use both brown and granulated sugar for this
  • Egg- I always use large eggs
  • Baking soda- for leavening
  • Cinnamon- a must with oatmeal cookies
  • Vanilla extract- always use pure vanilla extract
  • All-purpose flour- be sure to spoon and level it in the measuring cup – don’t pack it.
  • Quick Oats- Make your own quick oats if you only have rolled or old fashioned oats.
  • Chocolate chips- feel free to use any kind of chocolate you like
  • Toppings- of your choice (see below)
  • Sweetened condensed milk- make sure you’re not using evaporated milk. This is what gives the magic bar a thick, creamy and chewy sweet experience that you’ll love. 

Magic Bar Toppings

Add up to 4 cups of your favorite oatmeal cookie mix-ins:

  • Butterscotch Chips
  • Chocolate chips (white, semi-sweet, or milk)
  • Peanut Butter Chips
  • Raisins
  • Coconut
  • Nuts
  • Toffee Chips
  • M&Ms or Reese’s Pieces or chopped peanut butter cups… or any candy
  • Or anything else your heart desires!

How to make oatmeal magic bars

  1. Prepare oven: Preheat oven to 350°F. Line a 9×13” pan with foil or parchment and spray well with cooking spray. These are very sticky and the foil helps remove them easily from the pan, but it’s not mandatory.
  2. Make the dough: Cream butter and sugars in the bowl of an electric mixer fitted with a paddle attachment. Beat in egg and vanilla. Mix in baking soda and cinnamon. Slowly beat in flour. Mix in oats.
  3. Bake: Press dough into pan. Dough will be sticky so it helps to spray your hands with cooking spray. It will be a thin layer on the bottom of the pan. Bake for 10 minutes.
  4. Remove hot pan from oven and sprinkle evenly with toppings. Pour sweetened condensed milk evenly over the top (try to avoid having it touch the sides of the pan). Return to oven and bake for 25-30 more minutes until the edges are browning and the top seems semi-set. 
  5. Store: Cool completely before cutting. They’ll be very gooey – easier to cut once fully cool. Store in an airtight container for up to 4 days or freeze in a single layer for up to 3 months.

Prep Time 20 minutes

Ingredients
 

  • ½ cup (113g) unsalted butter , softened
  • ½ cup (100g) packed brown sugar
  • ¼ cup (50g) granulated sugar
  • 1 large egg
  • ½ teaspoon baking soda
  • 1 teaspoon cinnamon
  • 1 teaspoon vanilla extract
  • 1 cup (124g) all-purpose flour
  • 1 ½ cups Quick Oats
  • 2 cups some sort of chocolate chips (see note)
  • 2 cups additional toppings (see note)
  • 1 14 ounce can sweetened condensed milk

Instructions

  • Preheat oven to 350°F. Line a 9×13” pan with foil or parchment and spray well with cooking spray. These are very sticky and the foil helps remove them easily from the pan, but it’s not mandatory.
  • Cream butter and sugars in the bowl of an electric mixer fitted with a paddle attachment. Beat in egg and vanilla. Mix in baking soda and cinnamon. Slowly beat in flour. Mix in oats.
  • Press dough into pan. Dough will be sticky so it helps to spray your hands with cooking spray. It will be a thin layer on the bottom of the pan. Bake for 10 minutes.
  • Remove hot pan from oven and sprinkle evenly with toppings. Pour sweetened condensed milk evenly over the top (try to avoid having it touch the sides of the pan). Return to oven and bake for 25-30 more minutes until the edges are browning and the top seems semi-set. These stay sticky, and sometimes the chips (especially butterscotch) melt around the edges.

    1. Hi Jen! Thanks for clicking through on Pinterest. Unfortunately I don’t have a way to calculate WW points!

  2. These are incredibly rich, incredibly sweet and incredibly ADDICTING!!! I’ve never seen a 14 oz can of the sweetened condensed milk in my part of the world so to compromise I just used two of the smaller cans, This is pinned and its a keeper!
