Ingredients for Quick and Simple Oatmeal Peanut Butter Chocolate Chip Bars
- 1 cup creamy peanut butter
- 1/2 cup brown sugar (lightly packed)
- 1/4 cup honey or maple syrup
- 2 large eggs
- 1 tsp vanilla extract
- 1/2 tsp baking soda
- 1/4 tsp salt
- 1 1/2 cups old-fashioned rolled oats
- 1/2 cup flour (all-purpose or whole wheat)
- 1 cup chocolate chips (semi-sweet or dark)

Step-by-Step Instructions for Quick and Simple Oatmeal Peanut Butter Chocolate Chip Bars
Step 1: Preheat and Prepare
Preheat your oven to 350°F (175°C). Line an 8×8-inch or 9×9-inch baking pan with parchment paper or lightly grease it to prevent sticking. This helps the bars lift out cleanly once baked.
Step 2: Mix the Wet Ingredients
In a large mixing bowl, combine the peanut butter, brown sugar, and honey (or maple syrup). Whisk until smooth and creamy. Add in the eggs and vanilla extract, stirring until fully incorporated.
Step 3: Add the Dry Ingredients
Sprinkle the baking soda and salt into the wet mixture. Stir well, then fold in the rolled oats and flour. Mix until everything is just combined—don’t overmix or the bars might turn out dense.
Step 4: Fold in Chocolate Chips
Gently stir in the chocolate chips, saving a few to sprinkle on top if you’d like a prettier finish. The chips will melt into the batter slightly, creating gooey chocolate pockets in every bite.
Step 5: Bake
Spread the batter evenly into your prepared pan. Use a spatula to smooth out the top. Bake in the preheated oven for 22–26 minutes, or until the edges are golden brown and a toothpick inserted in the center comes out with just a few moist crumbs.
Step 6: Cool and Slice
Let the bars cool in the pan for at least 15–20 minutes. For cleaner cuts, let them cool completely before slicing into squares or rectangles. Enjoy them warm for gooey texture or at room temp for firmer bites.
Storage Instructions
To keep your Oatmeal Peanut Butter Chocolate Chip Bars fresh and chewy:
- Room Temperature: Store in an airtight container for up to 4 days. Keep them away from heat or sunlight to prevent the chocolate from melting.
- Refrigerator: For longer shelf life, refrigerate in a sealed container for up to 1 week. The bars will firm up slightly but remain chewy.
- Freezer: Wrap bars individually or layer between parchment paper in a freezer-safe container. They can be frozen for up to 3 months. Thaw at room temperature or microwave for 10–15 seconds for a warm treat.

Frequently Asked Questions
1. Can I use quick oats instead of rolled oats?
Yes, quick oats will work, but the texture will be softer and less chewy compared to rolled oats.
2. What can I substitute for peanut butter?
You can use almond butter, sunflower seed butter, or any nut/seed butter you prefer. Keep in mind it will slightly change the flavor.
3. Can I make these bars gluten-free?
Absolutely—just use certified gluten-free oats and replace the flour with a gluten-free blend or almond flour.
4. Are these bars suitable for vegans?
To make them vegan, use a plant-based egg substitute (like flax eggs) and opt for maple syrup instead of honey. Also, ensure your chocolate chips are dairy-free.
5. Can I reduce the sugar?
Yes, but reducing sugar may affect the texture. You can try using a sugar substitute or reduce the amount slightly to suit your preference.
6. How do I make these bars extra chewy?
Don’t overbake them—pull them from the oven when the center is still slightly soft. Also, using brown sugar and honey helps lock in moisture.
7. Can I add nuts or dried fruit?
Absolutely! Chopped walnuts, pecans, or dried cranberries make great additions. Just fold them in with the chocolate chips.
8. How long should I cool the bars before cutting?
Let them cool at least 15–20 minutes to firm up. For the cleanest cuts, wait until they are completely cool.
