Nutella Amaretto Brown Butter Blondies

Rich, chewy blondies featuring nutty brown butter, sweet amaretto liqueur, and swirls of chocolate hazelnut spread throughout. The brown butter adds a sophisticated toasted flavor that pairs beautifully with the almond notes from amaretto. Perfect for dinner parties or special occasions when you want an impressive dessert that's easier than brownies but more elegant than basic bar cookies. The marbled Nutella creates pockets of fudgy richness in every bite.

FAQ

Can I make these without amaretto?

Yes, substitute with 1/2 teaspoon almond extract or rum extract for similar flavor depth, or simply omit for plain brown butter blondies.

What if I don't have a 9x9 pan?

Use an 8x8 pan for thicker blondies (add 5-10 minutes baking time) or 9x13 for thinner bars (reduce time by 5-10 minutes).

How long do these keep?

Store covered at room temperature for up to 5 days, or wrap individually and freeze for up to 3 months for longer storage.
