Ingredients You’ll Need
- ½ cup (1 stick / 113 g) unsalted butter: This adds moisture and richness; ensure it’s at room temperature for easier melting.
- 1 cup (200 g) packed brown sugar: This gives a deeper sweetness and contributes to the chewy texture.
- ½ cup milk: Whole milk works best for creaminess, but you can switch to almond or oat milk for a dairy-free option.
- 1 cup (258 g) creamy peanut butter: Opt for a good-quality peanut butter for maximum flavor; crunchy peanut butter can also be used for added texture.
- 1 teaspoon vanilla extract: Enhances the overall flavor; pure vanilla is recommended instead of imitation.
- 1 pinch kosher salt: Balances sweetness and enhances the other flavors, don’t skip it!
- 3 cups (270 g) old-fashioned rolled oats: These create the bulk of the bars; quick oats can work, but will yield a different texture.
- 1 ½ cups (273 g) semi-sweet chocolate chips: Use good quality chocolate for melting; dark chocolate can be a wonderful alternative.
- 1 teaspoon coconut oil: Adding this helps the chocolate spread smoothly over the bars; you can replace this with vegetable oil if needed.
How to Make No-Bake Peanut Butter Oat Bars
- Prepare the Pan: Start by lining an 8×8-inch baking pan with parchment paper, allowing some overhang for easy removal later on.
- Melt the Mixture: In a medium saucepan over medium heat, combine the unsalted butter, packed brown sugar, and milk. Stir until smooth and bring to a gentle boil, cooking for 1 minute while stirring constantly.
- Combine Ingredients: Remove the saucepan from the heat and stir in the creamy peanut butter, vanilla extract, and a pinch of kosher salt until the mixture is creamy and fully combined.
- Incorporate Oats: Add the old-fashioned rolled oats to the peanut butter mixture, stirring until the oats are evenly coated and fully combined.
- Press into Pan: Firmly press the oatmeal mixture into the prepared baking pan. Spread it out into an even layer, making sure it’s compacted well.
- Melt the Chocolate: In a microwave-safe bowl, combine the semi-sweet chocolate chips and coconut oil. Heat in 30-second intervals, stirring in between until fully melted and smooth.
- Spread Chocolate: Pour the melted chocolate mixture over the oat layer, spreading it evenly across the top to cover it completely.
- Set in Fridge: Refrigerator time is key here! Chill the bars for about 30 to 45 minutes or until they’re fully set.
- Serve: Once chilled, lift the bars out of the pan using the parchment paper. Cut them into squares or rectangles, ready to be devoured!
Storing & Reheating
To keep your No-Bake Peanut Butter Oat Bars fresh, store them in an airtight container at room temperature for 3 to 5 days. If you prefer, they can last up to a week in the refrigerator. For long-term storage, wrap them tightly and freeze for up to 3 months. When you’re ready to enjoy again, simply thaw them at room temperature or pop them in the microwave for a few seconds, though keep in mind, texture may differ slightly after freezing.
Chef’s Helpful Tips
- Make sure your butter is just melted, not bubbling, to keep the texture smooth.
- For a fun twist, try adding nuts or dried fruit to the oat mixture for extra flavor and nutrition.
- If your mixture seems too crumbly, a splash more milk can help bind it together.
- Letting the bars set completely is crucial; cutting too soon can lead to messy squares.
- If you’re in a hurry, you can skip chilling the bars entirely and enjoy them immediately, though they’ll be softer.
