Nerdy Kitchen Science

• Maillard Reaction: Browning unsalted butter and toasting pecans develops complex flavor notes—think nutty, savory, and deep.
• Caramelization: Reducing cream soda allows its natural sugars to caramelize, enhancing the flavor of butterbeer.
• Brown Sugar + Room Temperature Eggs: This combo guarantees a moist crumb and chewy finish.

FAQs

Can I use coconut oil instead of butter? You can use melted coconut oil in place of the butter, but you’ll miss out on the browned butter flavor. The texture will still be chewy, but slightly softer.

Do I need a stand mixer? Nope! A medium bowl and wooden spoon work just fine. But if you’re feeling fancy, use the bowl of a large stand mixer with the whisk attachment.

How should I store them? In an airtight container at room temperature for up to 4 days, or freeze for up to 2 months.

Can I make these ahead for a party or movie theater night? Yes! These bars hold up great overnight and are perfect for sharing with a good friend while rewatching the Harry Potter movies or reading the Harry Potter books.
