How to Make No Bake Chocolate Oatmeal Bars

You don’t need any fancy equipment—just a saucepan, a bowl, and a pan to press them into. The reward? A pan of soft, chocolatey bars you can slice and share… or keep all to yourself.

STEP-BY-STEP INSTRUCTIONS:

Step 1: Line Your Pan
Start by lining an 8×8-inch or 9×9-inch square pan with parchment paper, leaving some overhang for easy lifting later.

Step 2: Melt the Wet Ingredients
In a medium saucepan over low heat, combine the coconut oil, peanut butter, maple syrup, cocoa powder, and salt. Stir gently as everything melts and blends together into a glossy, chocolatey mixture.

Step 3: Add Vanilla and Oats
Remove the pan from heat and stir in the vanilla extract. Then fold in the rolled oats until fully coated and combined.

Step 4: Add Chocolate Chips
Wait a couple of minutes before stirring in the chocolate chips so they don’t fully melt—this gives you nice chocolate chunks in the final bars. If you prefer them completely melted in, add them right away with the oats.

Step 5: Press and Chill
Transfer the mixture to your prepared pan. Use the back of a spoon or your hands (lightly greased or covered with parchment) to press the mixture firmly and evenly into the pan. Sprinkle extra chocolate chips on top if desired.

Step 6: Refrigerate
Place the pan in the fridge for at least 2 hours, or until firm. For quicker setting, place it in the freezer for 30–45 minutes.

Step 7: Slice and Serve
Once firm, lift the bars out using the parchment paper. Slice into squares or rectangles. Store in the fridge for a firm texture, or at room temperature for a softer, chewier bite.

HELPFUL TIPS:

• Use natural peanut butter (the kind with just peanuts and salt) for the best texture and flavor.
• To make these nut-free, swap peanut butter for sunflower seed butter.
• Want more texture? Add chopped nuts, shredded coconut, or dried fruit.
• For a deeper chocolate flavor, use dark cocoa powder or add a pinch of espresso powder.
• Don’t skip the chilling step—this helps the bars firm up and hold their shape.
