Let me introduce the easiest Chocolate Oatmeal Bars. Layers of oats, chocolate, dulce de leche and walnuts make up these irresistible bars!



  • 2 cups (270g) all-purpose flour
  • 2 cups (180g) traditional oats
  • 1 cup (200g) packed brown sugar
  • 1 teaspoon baking soda
  • 1/4 teaspoon salt
  • 1 cup (225g) unsalted butter, melted
  • 10 oz. (280g) semi-sweet chocolate, chips or chunks
  • 1 1/4 cups (150g) walnuts, chopped
  • 1 1/4 cups (300g) dulce de leche or thick caramel sauce


  1. Preheat oven at 350ºF / 180ºC.
  2. Spray or butter a 12x8-inch (20x30cm) pan and line bottom and two wider sides with a strip of wax or parchment paper.
  3. In a large bowl mix flour, oats, sugar, baking soda and salt.
  4. Add melted butter and mix with a spatula or wooden spoon until it’s all wet, no dry parts remaining.
  5. Reserve 1 1/2 cups of this mixture, and press the remaining onto the bottom of the prepared pan.
  6. Bake for about 15 minutes, until it starts to dry and color a bit.
  7. Take it out of the oven and immediately scatter the chocolate chunks over the hot base.
  8. Spread with a spoon or spatula and sprinkle chopped walnuts evenly on top.
  9. Add the dulce de leche or caramel by spoonfuls on top of the walnuts. It will not cover the whole surface. That’s OK.
  10. Scatter the reserved 1 1/2 cups of oatmeal mixture and bake for an additional 15-20 minutes, until it bubbles and starts to color.
  11. When you take it out of the oven, run a smooth knife along the sides to separate any dulce de leche that might have stuck and make it hard to unmold later.
  12. Let cool completely on a wire rack.
  13. Lift the paper to take out the whole block from the pan and cut into squares or rectangles.


Use pecans if you prefer.
