Ingredients Needed
Oatmeal cookie base:
- All-purpose flour
- Baking soda
- Salt
- Unsalted butter (room temperature)
- Light brown sugar (lightly packed)
- Large eggs (room temperature)
- Vanilla extract
- Quick oats (not old-fashioned)

How to Make the Recipe
Below is a concise overview. For the full recipe with measurements and details, see the recipe card.
Step 1 — Make the oatmeal cookie base. Whisk the dry ingredients together in a medium bowl. In a mixer (hand or stand with paddle), cream the butter and brown sugar, then add eggs and vanilla. Reduce speed, add the dry mixture until just combined, then fold in quick oats by hand.
Step 2 — Press base into the pan. Reserve about one-third of the dough for the topping. Press the remaining two-thirds into a generously greased 13″ x 9″ pan. If the dough is sticky, use a sprayed spatula or clean hands.
Step 3 — Make the chocolate pecan fudge. In a heavy-bottomed saucepan over medium heat (or a double boiler), combine chocolate chips, sweetened condensed milk, butter, and vanilla. Stir until smooth, then fold in chopped pecans and remove from heat.
Step 4 — Assemble and bake. Spread the warm fudge evenly over the oatmeal base. Break the reserved cookie dough into small to medium clumps and scatter them over the fudge. Bake at 350°F for 25–30 minutes, until the topping is lightly golden and the fudge has a shiny surface. Cool in the pan before cutting.
Storage
Store bars in a well-sealed container at room temperature or in the refrigerator. To freeze, cool completely, cut into squares, freeze on a sheet until firm, then wrap individually and place in an airtight container or freezer bag. Thaw in the refrigerator before serving.
Helpful Tips
- Baking pan: A 13″ x 9″ pan is ideal, but a 15″ x 10″ sheet pan also works; baking temperature and time remain the same.
- Pan release: Use a flour-based baking spray or line the pan for easier removal.
- Use an oven thermometer: Oven temperatures vary—an oven thermometer ensures accurate baking results.
- Sticky dough: The oatmeal cookie base is sticky. Spray your spatula or use your hands to press it into the pan.
- Reserve dough for topping: Set aside roughly one-third of the dough to crumble over the fudge layer.
- Melting chocolate: Use a heavy-bottomed saucepan or a double boiler and stir constantly until smooth.
- Cool before cutting: Let bars cool in the pan for cleaner slices while still remaining fudgy.
Recipe FAQs
A 13″ x 9″ baking pan works well. If you prefer, a 15″ x 10″ sheet pan will also produce great results.
Yes. Walnuts or almonds are good substitutes for pecans and will work nicely in the fudge layer.
Keep them in a well-sealed container at room temperature or refrigerated. For longer storage, freeze individual squares wrapped tightly.
