Golden Orange Cake

This bundt cake starts with a box cake mix but goes well beyond basic with buttermilk, fresh orange zest, golden raisins, and chopped walnuts folded into the batter. The buttermilk and baking soda react to give the crumb extra lift and tang, while the orange peel perfumes every slice with bright citrus.

Four minutes of beating on medium speed is what develops the structure here. That extended mix time incorporates air and activates the gluten just enough for a tight, even crumb that holds up in the bundt shape without being dense. The golden raisins plump slightly during baking, creating little pockets of sweetness throughout.

The orange glaze drizzled on top ties it all together: melted butter, powdered sugar, more grated orange peel, and fresh orange juice. It sets to a thin, shiny shell that cracks when you slice into it.

Pro Tips

• Grease and flour the bundt pan thoroughly, especially every ridge and curve. Bundt cakes are notorious for sticking, and this batter is dense enough that stuck pieces won’t come free cleanly.
• Use real buttermilk, not a milk-and-vinegar substitute. The fat content and culture in real buttermilk give the cake a richer flavor and more tender crumb.
• Cut the golden raisins into smaller pieces before folding them in. Whole raisins are heavy and sink to the bottom during the long bake.

Variations

• Swap walnuts for pecans and add a teaspoon of cinnamon for a warmer, autumn-spiced version.
• Replace orange zest and juice with lemon for a bright lemon drizzle bundt cake.
• Fold in dried cranberries instead of raisins for a tart, festive twist.
