Fudge Nut Bar Recipe:

These oatmeal fudge bars are amazing. You might remember these chocolate oat squares from your school lunch back in the day.  The reason lunch ladies made these is because the recipe makes a huge pan.

The base is an oatmeal cookie with the yummy flavors of butter and brown sugar.  The base is topped with a rich chocolate fudge with chopped nuts.  Then, to top it off, some of the base that been set aside gets sprinkled over it.

Let’s talk about the fudge layer.  It’s luscious, and thick and sweet and chocolaty.  And we aren’t just talking about a thin little layer.  The chocolate fudge goes from crust to crust in an even, hefty layer.

These oatmeal fudge bars are perfect to feed a crowd, to share with friends and family at the holidays, or to prepare for a bake sale.  The recipe makes huge portion which fills a jelly roll pan (find a link to one in our Amazon store) in a layer. The fudge nut bars measure around an inch in thickness once baked.

The original recipe intends for the fudge nut bars to be cut into small bars.  For a bake sale, cut them in large squares, put two cookies in a zip lock bag, and you are ready to roll.  You can easily get 24 super large bars from a pan of old fashioned oatmeal fudge bars.

I found this recipe in my handy, dandy Farm Journal, Homemade Cookie Cook Book. It’s my go-to when I’m wanting to find a new cookie to try.  I made these for the church bake sale.

Notes About Fudge Nut Bars with Oatmeal:

  • Use a jelly roll pan.  For easy transport and storage, buy one that has a lid like this one.
  • Parchment paper is an easy alternative to greasing a pan.  Line the jelly roll pan with a piece of parchment that is longer than the sheet pan.  You do not need to grease the parchment paper.  Once the bars are cooled, pull out the cookies and the parchment will peel right off.
  • Margarine can be substituted for butter in these fudge nut bars with oatmeal if desired.
  • Be sure to use quick oats NOT old fashioned oats.
  • To easily press the oatmeal cookie base, put your hand in a small plastic sandwich bag and press with the bag so it does not stick to your fingers.
  • Use a double boiler for the fudge layer. If you do not have one, then follow this method. Put water in a saucepan and bring to a boil. Find a glass bowl that will nestle over top the pan.  Be sure the water is not touching the bottom of the bowl.  This will gently melt the chocolate, sweetened condensed milk, and butter to form the perfect fudge.
  • Use sweetened condensed milk. Do not use evaporated milk.  1 cup sweetened condensed milk is not quite an entire 14 ounce can.  The rest is a treat for the chef.  Try sweetened condensed milk in your coffee. Yum!
  • An offset spatula is the perfect tool to spread the chocolate fudge layer from crust to crust.
  • Chopped pecans or walnuts are my nuts of choice for oatmeal fudge bars.
