Introduction

These Chocolate Chip Peanut Butter Oatmeal Bars are a perfect combination of chewy oats, creamy peanut butter, and sweet chocolate chips. They make a delicious and satisfying snack or dessert that’s easy to whip up for any occasion.

A stack of four thick, square blondie bars is shown on a white napkin on a white marbled surface. Each blondie has a light golden brown base filled with dark brown chocolate chips scattered throughout. On top of each blondie are scattered whole light tan peanuts and larger chunks of dark chocolate, adding texture and contrast. The edges of the bars are clean-cut and slightly crumbly, showing the moist and dense texture inside. Around the stack, some extra peanuts and small pieces of chocolate are scattered, with a blurry glass of milk visible in the background. photo taken with an iphone --ar 4:5 --v 7

Ingredients

1 1/2 cups rolled oats
1/2 cup flour (all-purpose or whole wheat)
1/2 tsp baking soda
1/4 tsp salt
1/2 cup peanut butter (smooth or chunky)
1/2 cup brown sugar (packed)
1/4 cup honey or maple syrup
1/4 cup butter (softened)
1 large egg
1 tsp vanilla extract
1/2 cup mini chocolate chips (or regular chips)

Instructions

Step 1: Preheat your oven to 350°F (175°C) and grease or line a 9×9-inch baking pan with parchment paper.
Step 2: In a medium bowl, whisk together the oats, flour, baking soda, and salt until evenly combined.
Step 3: In a separate large bowl, beat together the peanut butter, brown sugar, honey (or maple syrup), softened butter, egg, and vanilla extract until the mixture is smooth.
Step 4: Gradually add the dry oat mixture into the wet ingredients and mix just until combined.
Step 5: Fold in the chocolate chips gently to distribute evenly throughout the batter.
Step 6: Spread the batter evenly into the prepared baking pan, smoothing the top with a spatula.
Step 7: Bake for 18–22 minutes, or until the bars are golden and a toothpick inserted in the center comes out clean.
Step 8: Allow the bars to cool completely in the pan before slicing into squares for serving.

Tips & Variations

For added crunch, try folding in chopped nuts like walnuts or pecans along with the chocolate chips.
Use natural peanut butter for a less sweet, more pronounced peanut flavor.
Swap the chocolate chips for dried fruit like cranberries or raisins for a different twist.
To keep bars softer, slightly underbake them and let them set as they cool.

Storage

Store leftover bars in an airtight container at room temperature for up to 4 days. For longer storage, refrigerate for up to one week or freeze for up to 3 months. To enjoy, reheat slightly in the microwave or let thaw at room temperature.

FAQs

Can I substitute the flour with a gluten-free option?

Yes, you can use a gluten-free all-purpose flour blend to make these bars gluten-free. Just ensure your oats are certified gluten-free as well.

Can I make these bars vegan?

To make a vegan version, replace the egg with a flax egg (1 tbsp ground flaxseed mixed with 3 tbsp water) and use maple syrup instead of honey. Use a plant-based butter substitute as well.
