👩‍🍳 How to Make Peanut Butter Bars with Oatmeal (Step-by-Step Instructions with Detailed Photos)

Step 1. Add Peanut Butter and Honey to a Saucepan

Add 1 cup of creamy peanut butter together with 1/2 cup of honey in a medium saucepan.

Step 2. Melt the Peanut Butter and Honey

Turn the burner on medium heat. Melt the peanut butter and honey until it is smooth and well blended. This will take a few minutes depending on how hot your burner gets. Keep stirring the mixture as it melts using a heat-resistant spatula so the peanut butter and honey won’t stick to the bottom of the saucepan.

Step 3. Thoroughly Mix Peanut Butter and Honey

Continue to stir the peanut butter and honey mixture until thoroughly mixed. Then, turn the burner off. Keep the pot on the burner, as it will still keep the peanut butter mixture warm and smooth, making it easier to add the rolled oats in the next step.

Step 4. Add Half of the Oats

Gradually add half of the 3 cups of old-fashioned oats to the honey and peanut butter mixture. It is easier to stir the mixture when the oats are added a little at a time. Keep stirring the peanut butter oat mixture so it won’t stick to the bottom of the pot.

Step 6. Line a Pan with Aluminum Foil

Overlap a piece of aluminum foil in an 8×8 inch square pan or baking dish, that way the peanut butter bars can be easily removed from the pan. Then, spray the aluminum foil lightly with cooking spray so the bars won’t stick to the aluminum foil. After that, use your hands to press the peanut butter mixture in an even layer into the pan.

Tip: You can also use a piece of parchment paper instead of aluminum foil.

Step 7. Make a Chocolate Topping for the Peanut Butter Bars (Optional)

This part is optional, but highly recommended! To make chocolate peanut butter oatmeal bars, all it takes is to make a chocolate drizzle using melted chocolate chips. Start by putting 1/2 cup of chocolate chips in a small microwave-safe bowl.

Step 8. Melt the Chocolate Chips

Put the bowl of chocolate chips in the microwave for one minute at power level 6, then stir. Then another minute at power level 6 and stir. If the chocolate chips are not melted enough, do it again for 30 seconds at power level 6. After that, take the chocolate chips out of the microwave and stir them again.

Step 9. Spread the Melted Chocolate on Half of the Peanut Butter Bars

Spread the melted chocolate chips on top of one side of the bars. After that, it is best to put the peanut butter bars in the refrigerator before cutting them into squares so they can become firm and the chocolate topping can set.

Note: If you want a thick layer of chocolate on top of the bars, or want the melted chocolate chips on both sides, double the amount of chocolate chips in step 7.

Step 10. Cut the Peanut Butter Bars into Squares

After chilling the peanut butter bars for about 20 minutes in the refrigerator, cut them into 16 squares. You can cut smaller squares if you prefer, since the peanut butter bars are quite filling to the tummy. After cutting the squares, they are best stored in the refrigerator so they won’t become too soft.
