Step 1: Preheat your Oven
Preheat your oven to 350°F (175°C). This ensures your brownie cooks evenly.

Add 1 cup of sugar and 1 cup of dark brown sugar to the melted butter. Mix until well combined.
Step 4: Incorporate the Eggs and Vanilla

If You’re Curious
The addition of espresso powder in this Chocolate Peanut Butter Skillet Brownie may seem unusual, but it enhances the chocolate flavor immensely. It doesn’t make the brownies taste like coffee, but instead, it deepens the chocolate notes, making each bite even more indulgent. If you’re not a fan of espresso, you can omit it without any loss in flavor.
Shelf Life & Storage
These brownies can be stored in an airtight container at room temperature for up to 3 days. For longer storage, you can refrigerate them for up to a week. If you want to keep them even longer, consider freezing individual pieces wrapped in plastic wrap and then placed in a freezer-safe bag. They can be frozen for up to 3 months. Just reheat them in the oven or microwave when you’re ready to enjoy!
