Directions for Triple Peanut Butter Oatmeal Bars

Let’s make these Triple Peanut Butter Oatmeal Bars!

Prep the Oven and Pan

I preheat the oven to 350°F (175°C) and line an 8×8-inch baking dish with parchment paper or spray with nonstick cooking spray.

Mix Wet Ingredients

In a large bowl, I combine ½ cup melted butter, ½ cup creamy peanut butter, ¼ cup granulated sugar, and ½ cup brown sugar, stirring until smooth.

Add Egg and Vanilla

I beat in 1 large egg and 1 tsp vanilla extract until fully incorporated.

Prepare Dry Ingredients

In a medium bowl, I whisk together 1 cup all-purpose flour, ½ tsp baking soda, and ¼ tsp salt.

Combine and Mix

I gradually add the dry ingredients to the wet mixture, stirring until just combined. I fold in 1 ½ cups rolled oats, 1 cup peanut butter chips, ½ cup chopped peanuts, and ½ cup halved mini peanut butter cups until evenly distributed.

Bake and Cool

I spread the batter evenly into the prepared baking dish and bake for 20–25 minutes, until the edges are golden and a toothpick inserted in the center comes out clean. I let the Triple Peanut Butter Oatmeal Bars cool completely before cutting into 9 squares.

FAQs About Triple Peanut Butter Oatmeal Bars

Here are some frequently asked questions about Triple Peanut Butter Oatmeal Bars:

Can I use natural peanut butter instead of creamy peanut butter in this recipe?
Yes, you can substitute natural peanut butter for creamy peanut butter in this recipe. However, keep in mind that natural peanut butter tends to have a thinner consistency and may affect the texture of the bars slightly. You may need to adjust the other ingredients accordingly to achieve the desired consistency.

Can I omit the peanuts if I have a nut allergy?
Absolutely! If you or someone you’re serving has a nut allergy, you can omit the chopped peanuts from the recipe without sacrificing flavor. You can also substitute them with additional peanut butter chips or mini peanut butter cups for a nut-free alternative.

Can I use quick oats instead of old-fashioned rolled oats?
While old-fashioned rolled oats provide the best texture for these bars, you can use quick oats as a substitute if that’s what you have on hand. Just be aware that quick oats will result in a slightly softer texture compared to old-fashioned rolled oats. The bars may also bake a bit faster, so keep an eye on them to prevent over-browning.

Can I make these bars gluten-free?
Yes, substitute the all-purpose flour with a 1:1 gluten-free flour blend and ensure the oats are certified gluten-free for a gluten-free version.

Can I add other mix-ins to the recipe?
Absolutely! Try adding ¼ cup dried cranberries or white chocolate chips for a different flavor profile while keeping the Nutty Oat Treat vibe.
