These semi-homemade brownies are the best of both worlds: quick to make, but with a rich, homemade flavor thanks to a classic penuche frosting. The brownies bake up fudgy and tender, then get topped with a warm brown sugar frosting that sets into a creamy, caramel-like layer. Toasted pecans add the perfect crunch and depth of flavor.
This dessert is ideal for potlucks, parties, or whenever you want a reliable treat that tastes bakery-level without the extra effort. You can use your favorite boxed brownie mix or make your own from scratch — the penuche frosting makes either version taste irresistible.

How to Store
Refrigerate: Store brownies in an airtight container for up to 4 days. The penuche frosting stays smooth and creamy when chilled.
