Macadamia Mandelbrot

Mandelbrot is the Jewish cousin of Italian biscotti, and this version puts a tropical spin on the classic with chopped macadamia nuts, orange juice, and fresh orange zest. The dough gets shaped into logs, baked once, sliced on the diagonal, then baked again until golden and crunchy. The result is a crisp, dry cookie built for dunking.

Beating the eggs and oil together for a full five minutes creates the airy, fluffy base that gives mandelbrot its lighter texture compared to denser biscotti. This isn’t a step to rush. That extended beating incorporates air and emulsifies the oil so the dough stays workable.

The almond extract and orange zest give these a fragrant, bakery-shop aroma that fills the kitchen during both bakes. Chilling the dough for an hour before shaping firms up the oil-based dough so it holds its log shape on the baking sheet instead of spreading flat.

Pro Tips

• If the dough feels sticky after mixing, add flour a tablespoon at a time until it’s manageable. Don’t add more than ½ cup extra
• Use a serrated knife for slicing the warm logs. A straight blade crushes the soft interior
• Place slices cut-side up for the second bake so both faces get evenly crisped
• These keep for weeks in an airtight container, making them great for gift-giving

Variations

• Swap macadamia nuts for traditional almonds for a classic mandelbrot
• Fold in white chocolate chips before shaping the logs for a sweeter version
• Add a teaspoon of cinnamon to the dough for a warmly spiced cookie
