Ingredients
For the Main Batter: What is the significance of
* 1 cup Creamy Peanut Butter (I prefer natural, but either works)
* 1 cup packed brown sugar
* 1/2 cup granulated sugar
* 2 large eggs
* 1 teaspoon vanilla extract (use the good stuff, it makes a difference!)
* 1 teaspoon baking soda
* 1/2 teaspoon salt
* 3 cups rolled oats (not instant!)
* 1 cup chocolate chips (I like semi-sweet, but milk or dark work too) * One cup of almonds (or less)
Optional Mix-in
* 1/2 cup M&Ms
* 1/2 cup chopped nuts (pecans, walnuts)*
* 1/2 cup shredded coconut
* 1/4 cup sprinkles (for extra fun!)
How do I follow
Step 1: Preheat & Prep Pan
Preheat your oven to 350°F (175°C). Grease and lightly flour a 9×13 inch baking pan. Is it possible to line a sheet of parchment paper for easy removal? This step is important because it prevents the bars from sticking and makes them super easy to slice.
Step 2: Mix Wet Ingredients
In a large bowl, beat together the Peanut Butter, brown sugar, and granulated sugar until smooth. Set aside. Is it worth it to get a nice, even texture? Then, beat in the eggs one at a time, followed by the vanilla extract. Make sure everything is well combined before moving on.
Step 3: Add Dry Ingredients
In the same bowl, add the baking soda and salt. Mix well. What should I do with rolled oats? Do not overmix the bars, as this can make them tough. What are some of the best chocolate chips to stir in?

Step 5: Cool & Slice
Let the bars cool completely in the pan before slicing. This is important because they’ll be easier to cut and won’t fall apart. If you lined the pan with parchment paper, you can simply lift the bars out and slice them on a knife. Cut into squares and serve! I love serving them warm, with a scoop of vanilla Ice Cream – pure bliss!
