Peanut Butter Brownie Truffle Bars Recipe: Step-by-Step Guide

Creating these Peanut Butter Brownie Truffle Bars is a straightforward process. Follow these steps for success:
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This ensures your brownies will bake evenly.
Step 2: Prepare the Baking Pan
Line a 9×9 inch baking pan with parchment paper, allowing some overhang for easy removal later.
Step 3: Mix the Brownie Batter
In a large mixing bowl, combine the unsweetened cocoa powder, granulated sugar, light brown sugar, and a dash of salt. Whisk these dry ingredients together until well blended.
Step 4: Add Wet Ingredients
Stir in the melted unsalted butter and vanilla extract into the dry mixture. Mix until combined. Then, gently fold in the all-purpose flour until just incorporated, being careful not to overmix.
Step 5: Bake the Brownies
Pour the brownie batter into the prepared pan, spreading it evenly. Bake for 20-25 minutes or until a toothpick inserted in the center comes out with a few moist crumbs. Remove from the oven and let it cool completely.
Step 6: Prepare the Peanut Butter Filling
In a separate bowl, combine the creamy peanut butter, powdered sugar, melted unsalted butter, and vanilla extract. Mix until smooth and creamy.
Step 7: Add Crunch
Gently fold in the Rice Krispies cereal into the peanut butter mixture, ensuring they’re evenly coated.
Step 8: Assemble the Bars
Once the brownie layer has cooled, spread the peanut butter mixture evenly over the top.
Step 9: Make the Chocolate Coating
In a microwave-safe bowl, melt the semi-sweet chocolate chips or chocolate candy coating in 30-second intervals, stirring in between until fully melted and smooth.
Step 10: Coat the Bars
Pour the melted chocolate over the peanut butter layer, spreading it evenly to cover the entire surface.
Step 11: Chill and Set
Refrigerate the bars for at least 2 hours or until the chocolate coating is completely set.
Step 12: Slice and Serve
Once set, lift the bars out of the pan using the parchment paper overhang and cut them into squares. Serve and enjoy!
Allergy-Friendly Swaps

If you have dietary restrictions or allergies, consider these swaps:
- Gluten-free option: Substitute all-purpose flour with a gluten-free flour blend.
- Vegan option: Use coconut oil instead of butter and a dairy-free chocolate for the coating.
- Peanut-free option: Replace peanut butter with almond butter or sunflower seed butter.
Little Things that Matter
Here are some tips to ensure your Peanut Butter Brownie Truffle Bars are perfect:
- Let the brownies cool completely before adding the peanut butter layer to prevent melting.
- Use quality chocolate for the coating, as it significantly impacts the flavor.
- For best results, refrigerate the bars overnight for flavors to meld.
Keep It Fresh: Storage Guide
To keep your Peanut Butter Brownie Truffle Bars fresh, store them in an airtight container. They can be kept at room temperature for up to 3 days or in the refrigerator for up to a week. For longer storage, you can freeze them for up to 3 months. Just ensure they are well-wrapped to prevent freezer burn.
Popular Questions
Can I use natural peanut butter for the filling?
Yes, you can use natural peanut butter, but it may result in a slightly different texture. Natural peanut butter tends to be thinner, so you might need to adjust the powdered sugar to achieve the right consistency.
Can I make these bars ahead of time?
Absolutely! These bars can be made in advance and stored in the fridge or freezer. Just make sure to let them come to room temperature before serving for the best flavor and texture.
What can I substitute for the Rice Krispies?
If you don’t have Rice Krispies, you can use any crispy cereal or even crushed graham crackers for a different texture and flavor.
How do I know when the brownies are done baking?
The brownies are done when a toothpick inserted into the center comes out with a few moist crumbs. If it comes out clean, they may be overbaked.
