Cookie Butter Bars Cooking Guide

Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). This ensures that your Cookie Butter Bars bake evenly and come out perfectly golden.
Step 2: Prepare the Baking Pan
Line a 9×13-inch baking pan with parchment paper, leaving some overhang on the sides for easy removal later. This little trick makes cutting and serving a breeze!
Step 3: Cream Butter and Sugar
In a large mixing bowl, cream together the 12 tablespoons of unsalted butter and 3/4 cup of light brown sugar until the mixture is light and fluffy. This should take about 2-3 minutes with a hand mixer or stand mixer.
Step 4: Add Vanilla
Add in 1 teaspoon of vanilla extract and mix until combined. The aroma will be irresistible!
Step 5: Combine Dry Ingredients
In another bowl, whisk together the 1 cup of old-fashioned oats, 1 teaspoon of baking soda, 1/4 teaspoon of salt, and 1-1/4 cups of all-purpose flour. This mixture will create the foundation for your bars.
Step 6: Mix Wet and Dry Ingredients
Gradually add the dry mixture to the butter and sugar mixture, stirring until just combined. Be careful not to overmix; you want your bars to remain tender!
Step 7: Fold in Cookie Butter and Chocolate Chips
Now it’s time for the star ingredient! Fold in 1 cup of cookie butter and 1 cup of chocolate chips. The cookie butter will create a rich, creamy texture that will make these bars unforgettable.
Step 8: Spread into the Pan
Pour the mixture into your prepared baking pan, spreading it evenly with a spatula. Don’t worry about making it perfect; the bars will level out as they bake.
Step 9: Bake
Bake in the preheated oven for 25-30 minutes, or until the edges are golden brown and the center is set. You can check for doneness by inserting a toothpick in the center; it should come out with a few moist crumbs.
Step 10: Cool and Serve
Once baked, remove the pan from the oven and let it cool in the pan for about 10 minutes. Then, use the parchment paper to lift the bars out of the pan and let them cool completely on a wire rack. Once cool, cut into squares and enjoy!
Seasonal Spins

- Pumpkin Spice Cookie Butter Bars: Add 1/2 cup of pumpkin puree and 1 teaspoon of pumpkin spice to the batter for a fall-inspired treat.
- Mint Chocolate Cookie Butter Bars: Fold in 1/4 teaspoon of peppermint extract and use mint chocolate chips for a refreshing twist.
- Peanut Butter Cookie Butter Bars: Substitute half of the cookie butter with peanut butter for a nutty flavor.
- Caramel Drizzle Cookie Butter Bars: Drizzle caramel sauce on top after baking for an extra indulgent touch.
Slip-Ups to Skip
- Don’t rush the butter and sugar creaming process; it’s crucial for the bars’ texture.
- Avoid using quick oats or steel-cut oats; they won’t provide the right chewiness.
- Make sure your baking soda is fresh; expired baking soda can affect the rise.
- Don’t overbake! Keep an eye on the bars, as they can go from perfectly baked to overdone quickly.
Best Ways to Store
Store your Cookie Butter Bars in an airtight container at room temperature for up to 4 days. If you want them to last a bit longer, you can refrigerate them for up to a week. For longer storage, wrap them tightly and freeze for up to 3 months. When you’re ready to enjoy, simply thaw at room temperature or warm them up in the microwave for a few seconds.
Helpful Q&A
Can I use a different type of cookie butter?
Absolutely! Feel free to experiment with different flavors of cookie butter, like almond or speculoos, to create a unique twist on this recipe.
Can I make these bars gluten-free?
Yes! You can substitute the all-purpose flour with a gluten-free flour blend. Just make sure it’s a one-to-one ratio substitute for the best results.
How can I make these bars vegan?
You can replace the butter with a vegan butter alternative and use a flax egg (1 tablespoon of flaxseed meal mixed with 2.5 tablespoons of water) instead of the egg, if your recipe calls for one. Be sure to choose a vegan cookie butter as well.
What can I use instead of chocolate chips?
If you prefer, you can leave out the chocolate chips or substitute them with dried fruits, nuts, or even white chocolate chips for a different flavor profile.
