Whisk together 1/2 cup all-purpose flour, 1/2 teaspoon baking powder, and 1/4 teaspoon table salt in a separate bowl. This dry mixture helps create a tender brownie texture, so take your time!
-
Combine the slightly cooled chocolate mixture with 1/3 cup light-brown sugar, 1/2 cup granulated sugar, 2 large eggs, 2 egg yolks, and 1 teaspoon pure vanilla extract until smooth. Then, stir in the flour mixture until thoroughly incorporated, followed by the remaining cup of chocolate chips.

Expert Tips for Chocolate and Peanut Butter Brownie Bites
-
Ingredient Quality: Use high-quality semisweet chocolate chips for a richer flavor. Cheaper brands may not melt as smoothly, impacting texture.
-
Mixing Technique: Avoid overmixing the batter after adding the flour. This helps keep your brownies tender instead of tough.
-
Chill the Batter: If the chocolate batter is too warm, chilling it briefly can help stabilize the mixture before adding the peanut butter swirls.
-
Swirling Method: For the best swirl effect, less is more. Lightly swirl the peanut butter into the chocolate without fully blending; this creates lovely marbled patterns.
-
Cooling Time: Be patient and let the brownies cool completely before cutting them. This ensures clean edges and prevents them from crumbling.
These tips will help you create the perfect chocolate and peanut butter brownie bites every time!

What’s the best way to store leftover brownies?
To maintain their wonderful texture, keep the chocolate and peanut butter brownie bites covered in an airtight container at room temperature for up to 3 days.

When you’re ready to enjoy, simply thaw them at room temperature or microwave for about 10-15 seconds for a fresh-baked experience!
What should I do if my brownies turn out too cakey?
If your brownie bites are overly cakey, it may be due to overmixing the batter after adding the flour, or perhaps they were baked for too long. To prevent this in the future, mix just until the dry ingredients are incorporated and always keep an eye on the baking time. Remember, a toothpick should come out with a few moist crumbs, not completely clean!
Are there any dietary considerations I should be aware of?
Absolutely! These chocolate and peanut butter brownie bites do contain common allergens like eggs and nuts. If you’re baking for someone with allergies, consider using egg substitutes like applesauce or flaxseed meal, and opt for nut-free butters if needed.
