Tips For the Best Peanut Butter Bars Follow these tips to make the best peanut cookie bars. Line your baking sheet with parchment paper. It is tempting to use cooking spray but they’ll come out of the pan much better with parchment paper.Use softened butter. The easiest way to soften butter is to take it out of the refrigerator 30-60 minutes before you make cookies. If your butter is not soft, cut into 1 tablespoon portions and place on a microwave safe plate. Microwave for 5 seconds. Be careful, however, because it will melt quickly.Do not overmix the cookie batter. Mix just until it’s all combined. HOW TO STORE Counter: You can store leftovers in an airtight container or ziploc bag at room temperature for up to 3 days. Freeze: Completely cooled oven baked cookie bars can be frozen in a freezer safe container or bag for up to 3 months. Defrosting: Thaw your peanut butter bars on the counter for a couple of hours. To enjoy a delicious warm cookie bar, simply pop the defrosted treats in the microwave for a few of seconds or in the oven for a minute or two.

Better Than Toll House Chocolate Chip Cookie Bars Chocolate Chip Coconut Cookie Bars Peanut Butter Chocolate Chip Cookie Bars Salted Caramel Chocolate Chip Cookie Bars FREQUENTLY ASKED QUESTIONS For perfect results every time, here are answers to the most common questions about cooking peanut butter cookie bars. Do I have to use parchment paper for the baking pan? YES. In addition to parchment paper, you can also line the baking dish with aluminum foil. Both work equally well. Make sure you have a slight overhang on the edges. This will eventually make it a lot easier to lift the baked cookie bar out of the pan. We do not recommend using non-stick spray or buttering and flouring the baking dish for this recipe. How do you know the perfect time to get the cookie bars out of the oven? For the cookie bars to be done they should be slightly puffed up, golden brown with crispy edges. The middle might still look underdone, but don’t forget the cookie bars will keep on cooking for a couple of minutes after they have been removed from the oven. When you insert a toothpick at the center it should come out clean or with a few moist crumbs on it. If there is still raw batter on the toothpick, keep the cookie bars in the oven for another couple of minutes. Can I double this recipe? Yes. You can double the recipe and bake it in a 9×13″ baking pan. You might have to add a couple of minutes to the baking time. However, start checking the cookie bars at the 20 minute mark to be sure you don’t overcook them.
