How to Make the Recipe
Here is a brief overview of how to make these warm and gooey, classic fudge nut bars. For the detailed recipe, please scroll down to the recipe card.
Make the oatmeal cookie base. Whisk all the dry ingredients together first in a medium-sized bowl. For mixing the wet ingredients, you can use either a hand mixer or a stand mixer that is fitted with a paddle attachment.
Once the wet ingredients are all mixed together and well blended, add in the whisked dry ingredients. Then, you will fold in your quick 1-minute oats with a spatula or spoon. Do not use your mixer for that part.
Add the oatmeal cookie base to the pan. Only use 2/3 of the oatmeal cookie mixture for the base. The rest you will use as a topping.
Make the chocolate pecan fudge layer. Add all of the ingredients—except the chopped pecans—to a medium-sized heavy-bottom saucepan. If you prefer, you can use a double boiler instead.
Continuously stir it all together over medium heat until the mixture has melted and is smooth in texture. Add in the chopped pecans, then remove from heat.
Spread out the chocolate pecan fudge layer. Immediately pour the chocolate pecan fudge onto the top of the oatmeal cookie base. Spread it out evenly using either a spatula or a spoon.
Add the reserved oatmeal cookie mixture. This is easiest to do with your hands. Just pull off small- to medium-sized clumps of the mixture and place them over the top of the chocolate pecan fudge.
Bake. Place it in the oven and bake for 25-30 minutes at 350ºF. Allow the fudge nut bars to cool before cutting into squares.
Helpful Tips
Baking pans. I used a 13-inch by 9-inch baking pan for this oatmeal fudge bars recipe, but you can also use a 15-inch x 10-inch sheet pan (or jelly roll pan). The baking temperature and baking time range are the same.
Use baking spray. For easy removal of your fudge nut bars, make sure to generously spray your baking pan with a flour-based baking spray.
Use an oven thermometer. This is a new tip I’ve been adding to my recipes because it is an important one. Baking any dessert in an oven that’s not set to the correct temperature could lead to wonky baked goods. Just get yourself an oven thermometer. They hook right to your oven rack and will give you an accurate temperature reading. Oh, and they’re inexpensive, too.
Oatmeal cookie base. This is very sticky and will be a little stubborn when trying to spread it out. Fear not, though; you can either spray a spatula to prevent the oatmeal cookie base from sticking to your spatula as you spread it out, or you can simply use your clean hands.
Set some cookie base aside. After you have made the oatmeal cookie base, make sure to have at least 2/3 of it for spreading into the pan. The remaining amount needs to be reserved for the topping.
If you forget, though, it’s not the end of the world. They will still taste phenomenally good!
Making the chocolate fudge. Originally, when I shared this recipe, I used a double boiler. I’ve since switched this to a heavy-bottom saucepan. Make sure to mix this together over medium heat.
Let it cool. Make sure to let the fudge nut bars cool before cutting into them. They’ll still be fudgy, but the cutting will be a little cleaner.
Storing fudge nut bars. Any fudge nut bars should be kept in a well-sealed food container at either room temperature or in the refrigerator.
Fudge Nut Bars FAQs
For this recipe, I used my 13-inch x 9-inch Nordic Ware baking pan. I love it because it cleans up nicely and has a cover that can double as a cookie sheet.
Yes, absolutely! If you don’t have pecans, you can use walnuts or almonds. You really can’t go wrong with any of them.
Fudge nut bars should be kept in a well-sealed food container at either room temperature or in the refrigerator.
Yes! After baking, allow them to cool. Then, cut into squares and freeze on a baking sheet until firm. Then, wrap individual squares in plastic wrap and store them in either a freezer bag or a well-sealed food container. Allow the bars to defrost in the refrigerator before serving.
