Let me start by saying, I know Pecans are for fall! But, hear me out, I was craving somehing fall like in the early summer heat this past week. I usually always stick to seasonal recipes, because I know that’s what most of us are looking for. I ended up breaking all the rules by putting this autumal recipe out on the very last day of May. Why not…lol!

So, whether you chose to make these now or save them for back to school, they are a great cookie bar. Keep reading to see what they are like and all the good stuff you need to make them yourself.

What Are These Cookie Bars Like

  • Difficulty – These cookie bars are super easy to make. The only part that requires a little time is pressing the dough into a rimmed cookie sheet. This could take a few minutes to make sure the dough stretches to the sides of the pan. Check the Recipe Tips section to read all about this.
  • Taste – The perfect nutty flavour from the pecans with a oat texture and a little of a chewy texture and caramelised flavour from the brown sugar. A great combo!
  • Serving – This recipe makes a cookie sheet sized recipe. I got 45 cookie bars from this batch. You can easily cut yours larger if you like. I found these the perfect size to go with a cup of tea or coffee.

Ingredients

  • Butter – This recipe uses unsalted butter at room temperature.
  • Sugars – I used a combination of packed brown sugar and granulated white sugar.
  • Eggs – Use room temperature large eggs.
  • Vanilla -Vanilla extract adds flavour to the cookie bars.
  • Flour – All purpose flour is the most common variety and it’s what I used for these cookies.
  • Baking soda – This is the rising agent used for the cookies.
  • Salt – A little salt enhances flavours.
  • Oats – I used rolled oats for this recipe. They are often referred to as old fashioned oats.
  • Pecans – Buy pecan halves and chop them yourself. This will give more flavour. You can toast them if you feel that you would like to. You can toast the pecans if you like. See How to Toast Pecans.

Substitutions

The only change I would recommend would be to switch the pecans for walnuts if you like. Other than that, stick to the recipe for best results.
