Molten Peanut Butter Brownie Cups – Fudgy Brownies with a Melting Peanut Butter Center

Molten Peanut Butter Brownie Cups are rich chocolate desserts baked with a soft fudgy texture and a warm peanut butter center.

As the brownies bake, the tops develop a thin crackled crust while the inside remains soft and dense. Hidden in the center, peanut butter melts into a creamy filling that slowly flows when the brownie is broken open.

The contrast between deep chocolate flavor and nutty peanut butter creates a warm dessert with a molten texture and glossy finish.
