(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

Directions

Preheat your oven to 350°F (175°C) and line an 8×8-inch baking pan with parchment paper.
In a large mixing bowl, beat together the softened butter and peanut butter until creamy. Add the brown sugar, eggs, and vanilla extract, mixing until combined.
In a separate bowl, combine oats, flour, baking soda, and salt. Gradually add this to the wet ingredients, stirring until everything is well combined. Add the peanut butter and chocolate chips, if using.
Spread the dough into the prepared pan, pressing it into an even layer.
For the streusel topping, melt the peanut butter and brown sugar together in a small saucepan over low heat. Stir in the oats and mix until combined. Sprinkle the streusel evenly over the oatmeal bar mixture.
Bake for 18-20 minutes or until a toothpick inserted comes out clean. Let cool completely in the pan before cutting into bars.
Drizzle with melted peanut butter before serving.

Variations

Healthy version: Replace half the butter with applesauce and use a lower-sugar peanut butter to make a healthier version of the bars.
Add chocolate: Incorporate chocolate chips into the dough or drizzle the bars with melted chocolate instead of peanut butter.
Seasonal twist: Add pumpkin pie spice or cinnamon for a cozy, fall flavor.

Storage/Reheating

FAQs

Can I use quick oats instead of old-fashioned oats?

Yes, you can use quick oats, though old-fashioned oats give a chewier texture.

How do I make these bars more chocolatey?

Add chocolate chips to the dough or drizzle melted chocolate over the top for a richer flavor.

Can I make these ahead of time?

Yes, these bars can be made a day or two in advance and stored in an airtight container.

How do I know when the bars are done?

The bars are done when they are golden brown on the edges and a toothpick comes out clean.

Can I use natural peanut butter?

Regular creamy peanut butter (like Jif) gives the best texture and flavor, but you can use natural peanut butter as a substitute.
