Step-by-Step Instructions
Follow these easy steps to make the perfect No-Bake Peanut Butter Oatmeal Bars:
Prepare the Mixture:
- Prepare the Pan: Line an 8×8-inch square baking pan with parchment paper or lightly grease it with cooking spray. This ensures the bars don’t stick and makes it easier to remove them once they’re set.
- Mix the Wet Ingredients: In a medium saucepan, combine the peanut butter, honey (or maple syrup), almond milk, and vanilla extract. Warm the mixture over low heat, stirring constantly until everything is fully combined and smooth. This should take about 2-3 minutes. If you’re adding chia seeds or flaxseeds, stir them in now.
- Combine with Oats: In a large mixing bowl, add the oats and salt (if using). Pour the warm peanut butter mixture over the oats and stir well until the oats are evenly coated and the mixture is thick and sticky.
Add Chocolate (Optional):
- Stir in Chocolate Chips: If you’re using chocolate chips, fold them into the mixture now. Be careful not to stir too much, as the chocolate chips can melt into the mixture if it’s too warm. If you prefer solid chocolate pieces, let the mixture cool for a few minutes before adding the chips.
Press and Chill:
- Press the Mixture into the Pan: Transfer the mixture into the prepared baking pan and use a spatula or your hands to press it down firmly into an even layer. This step is important to ensure the bars hold together once set.
- Chill in the Refrigerator: Place the pan in the refrigerator for about 20-30 minutes to allow the bars to firm up. The cooling process helps the peanut butter mixture set and makes it easier to cut into bars.
Cut and Serve:
- Slice into Bars: Once the mixture has chilled and set, remove it from the refrigerator. Using a sharp knife, cut it into 12 to 16 bars, depending on your preferred serving size.
- Serve and Enjoy: The No-Bake Peanut Butter Oatmeal Bars are now ready to be enjoyed! Keep any leftovers in an airtight container for up to 1 week in the fridge or up to 3 months in the freezer.
