Ingredients Notes
Most ingredients for these bars are kitchen staples, ensuring you need to buy minimal items. For the chocolate, opt for a high-quality dark chocolate for a richer flavor. If you prefer milk chocolate, that’s an acceptable substitution—just note it will yield a sweeter result. Creamy Peanut Butter works best for a smooth texture, but crunchy peanut butter can add an interesting twist. Ensure all ingredients are at room temperature before beginning for the best results.
Recipe Steps
Step 1
Preheat your oven to 350°F (175°C). Grease an 8×8-inch square baking pan or line it with parchment paper for easy removal later. Gather your ingredients, ensuring everything is measured out and ready to go.
Step 2
Melt chocolate and butter together in a microwave-safe bowl or over a double boiler, stirring occasionally, until smooth. Let it cool slightly before stirring in the sugar, vanilla extract, and eggs, one at a time, until well blended.
Step 3
Gently fold in the flour and salt into the chocolate mixture without over mixing. Pour the batter into the prepared pan, smoothing the top with a spatula to ensure it’s evenly distributed.
Step 4
Bake in the preheated oven for 20-25 minutes or until a toothpick inserted into the center comes out with only a few moist crumbs. Allow it to cool in the pan on a wire rack.
Step 5
While the brownies are cooling, warm the Peanut Butter slightly in the microwave for about 20 seconds to make it more spreadable. Pour the peanut butter over the cooled brownies and spread evenly. Allow it to set before cutting into bars.
Storage Options
These bars can be stored in an airtight container at room temperature for up to three days. For longer-term storage, wrap each bar tightly in plastic wrap, place them in a freezer-safe bag, and freeze for up to two months. To enjoy from frozen, thaw them overnight in the refrigerator and serve.
Variations & Substitutions
For a more indulgent version, you can add a layer of caramel between the brownie and peanut butter. If gluten-free is needed, use a 1:1 gluten-free flour blend. To cater to a vegan diet, swap out the eggs with flax eggs and ensure all other ingredients are vegan-friendly.
Serving Suggestions
These bars are perfect as a quick dessert at a family dinner or as a sweet snack at a casual gathering. Top optionally with a scoop of vanilla ice cream or a sprinkle of sea salt flakes for an elevated touch. They also make a delightful treat to pack along for picnics or as a welcome addition to a party platter.
Frequently Asked Questions
Can I use a different nut butter instead of peanut butter? Certainly! Almond or cashew butter both work well in this recipe and add their own unique flavors. Keep in mind that different nut butters have varying consistencies, so you might need to adjust slightly for texture.
How can I tell if the brownies are done baking? The best way to check is with a toothpick test. Insert it into the center of the brownies, and if it comes out with just a few moist crumbs, they’re ready. The brownies will continue to firm up as they cool due to carryover cooking.
What type of chocolate is best for this recipe? A semi-sweet or dark chocolate is recommended for its depth of flavor without being overly sweet. Feel free to experiment with chocolate chips, chunks, or even white chocolate for a fun twist.
