There’s something about the first bite of a cookies ‘n’ cream millionaire shortbread that feels like pure magic. You sink your teeth through that silky chocolate top, into the rich, fudgy base, and then hit that dreamy layer of cookies and cream nestled in the middle. It’s like a candy bar and your favorite childhood snack had a delicious love child. Whether you’re making these to impress or just treating yourself, this layered beauty is going to win hearts.

Behind the Recipe

This recipe came from a weekend experiment that spiraled into obsession. I had classic millionaire shortbread on the brain but also a serious craving for cookies and cream. So I thought, why not mash them up into one over-the-top treat? The result was everything I hoped for — indulgent, nostalgic, and dangerously good. After the first batch disappeared in a flash, it became a staple in my dessert rotation.

Recipe Origin or Trivia

Millionaire shortbread originated in Scotland, traditionally made with a buttery shortbread base, a thick caramel layer, and a chocolate topping. The name “millionaire” hints at its richness — not just in taste but in decadence. Over the years, bakers have added creative twists, from peanut butter swirls to sea salt sprinkles. This cookies ‘n’ cream version adds a playful American twist, using cream-filled cookies and a chocolate cookie base instead of the traditional shortbread.
