How to Make Crunchy Peanut Butter Bars with Dark Chocolate Drizzle
Prepare the Baking Dish: Start by lining a 9x13-inch baking dish with parchment paper. Make sure the paper extends over the edges; this will help you lift out the bars effortlessly later.
Create the Peanut Butter Mixture: In a large saucepan, combine natural peanut butter, honey, and unsalted butter. Cook this over medium heat while stirring occasionally. Continue cooking until the ingredients meld into a smooth, creamy mixture.
Add Flavor and Texture: Once your peanut butter mixture is smooth, remove the saucepan from heat. Stir in a teaspoon of vanilla extract and half a teaspoon of sea salt for added flavor.
Mix in the Oats and Peanuts: Fold in old-fashioned oats and crushed roasted peanuts using a spatula. Make sure the oats and peanuts are well-coated with the peanut butter mixture.
Press into Baking Dish: Pour your peanut butter-oat mixture into the prepared baking dish. Use a spatula or your hands to press down firmly, ensuring the mixture is evenly spread and compact.
Prepare the Dark Chocolate Drizzle: Using a double boiler, melt dark chocolate (70% cacao works best). Stir constantly to make sure the chocolate doesn't burn.
Drizzle the Chocolate: With the melted dark chocolate ready, use a spoon or a drizzle wand to artfully drizzle it over the mixture in the baking dish.
Chill and Set: Place the baking dish in the refrigerator for at least 2 hours to allow the bars and the chocolate to fully set.
Cut and Serve: Once set, use the overhanging parchment paper to lift the large block of deliciousness out of the dish. Cut it into bars or squares, and enjoy!
Tips and Tricks for Perfect Crunchy Peanut Butter Bars with Dark Chocolate Drizzle
Quality Ingredients: The taste of your bars will largely depend on the quality of the ingredients you use. Opt for natural, unsweetened peanut butter and high-quality dark chocolate for the best flavor.
Even Spreading: To ensure the peanut butter-oat mixture is evenly distributed in the baking dish, you might want to use the back of a spatula or the bottom of a glass to press the mixture down firmly. This will help achieve uniform texture and thickness across all bars.
Melt Chocolate Safely: If you don't have a double boiler, you can also melt the chocolate in a microwave. Heat it in 20-second intervals, stirring between each round, until smooth. Just be cautious to not overheat, as chocolate can easily burn.
Adjust Sweetness: Feel free to adjust the sweetness to your taste. If the bars are too sweet, you can reduce the honey or use a darker chocolate with higher cacao content for the drizzle.
Storage Solutions: These bars can be stored in an airtight container in the fridge for up to a week. If you'd like to enjoy them over a more extended period, you can also freeze them. Just make sure to separate individual bars with parchment paper to prevent them from sticking together.

Crunchy Peanut Butter Bars - FAQ
Absolutely, you can swap out the peanut butter for almond butter, cashew butter, or any other nut butter of your choice. Just keep in mind that the flavor profile will change slightly depending on the nut butter you choose.
If you're looking to up the protein content, consider adding a scoop or two of your favorite protein powder to the peanut butter mixture. You can also sprinkle some chia seeds or hemp seeds for added protein and nutrients.
Refrigerating the bars helps them to set properly and makes them easier to cut. However, once they are set, they can be stored at room temperature for a short period, especially if you're planning on eating them within a day or two. For longer storage, it's best to keep them refrigerated or frozen.
You can use quick oats if you'd like, but the texture will differ. Old-fashioned oats give a more chewy and substantial texture to the bars, while quick oats may result in a softer, less chewy bar.
