Aunt Dora's Rubber Bars

Dora Komaromi


OK, so the story is that I got this recipe from a co-worker about 20 years ago. I made a batch to take to a family function and the niece and nephews (and my brother) fell in love with them. They asked me what they were called and I said “Chocolate Rebel Bars,” but they (being little kids at the time) didn’t understand what I said and called them “Rubber Bars.” The name stuck and we still call them Rubber Bars!

How to Make Aunt Dora's Rubber Bars


  • 1Cream together 2 sticks of butter and the brown sugar; add eggs and vanilla. Beat with a mixer until incorporated.
  • 2Add the flour and baking soda; mix to combine.
  • 3Add the oatmeal, mix to incorporate. I like to use my hands like I would to mix meatloaf. If you have a heavy-duty hand mixer or a stand mixer you can use them instead.
  • 4Spread 2/3 of the oatmeal mixture into a buttered 13x9 baking pan. Press it in and smooth the top.
  • 5In a glass or ceramic bowl (microwave-safe) combine the bag of milk chocolate chips, sweetened condensed milk, vanilla and butter. Microwave for 30 seconds, stir, microwave for another 30 seconds; stir to combine and finish melting.
  • 6Pour the chocolate over the oatmeal mixture in the pan and spread evenly. Try to keep it just back from the sides of the pan -- it will burn while baking.
  • 7Crumble the remaining 1/3 of the oatmeal mixture unevenly over the chocolate.
  • 8Bake at 350 degrees for 25-30 minutes. If using a glass baking dish, lower your temp to 325 degrees and check after 25 minutes. The top should be light golden brown; the edges should not be darker than the middle. It's OK to take it out a little on the under-done side.
  • 9Let cool to room temperature before trying to cut. I like to refrigerate mine overnight. The next morning the whole thing pops out of the pan and I can cut it into any size bars I want. I usually cut into about 1 1/2 x 1 1/2 inches.
  • 10This is also good right out of the oven with vanilla ice cream on top melting all over...MMMMmmm!
