This cake is rooted in New Orleans baking traditions. While its exact origin is unclear, variations of this crunchy-topped yellow cake have been a favorite in Louisiana for decades and are often associated with classic local bakers and family kitchens.

Recipe walkthrough: Instructions

This overview summarizes the baking steps. Full quantities and detailed steps are in the recipe card below.

• Step 1: Sift the cake flour, salt, baking powder, and baking soda together, then set aside.
• Step 2: In a stand mixer (or a large bowl with a hand mixer), beat the butter and granulated sugar until light and fluffy.
• Step 3: Add the eggs one at a time, beating well after each addition.
• Step 4: Stir in the coconut and vanilla extracts, then combine thoroughly.

• Step 5: With the mixer on low, add the flour mixture in ½-cup increments, alternating with portions of the buttermilk.
• Step 6: Finish incorporating the flour, scrape the bowl, and ensure an even batter.
• Step 7: Generously grease the bundt pan with butter, using a brush to reach all grooves.
• Step 8: Sprinkle the bottom of the pan with granulated sugar, add the sweetened coconut flakes, then dust lightly with flour.

• Step 9: Pour the batter over the sugar-coconut layer, smooth the top, and bake until a wooden skewer inserted near the center comes out with only a few crumbs (about 50 minutes, ovens vary).
• Step 10: Let the cake rest in the pan for just 10 minutes after removing it from the oven, then turn it out onto a wire rack to cool completely. Prepare the glaze by whisking powdered sugar with evaporated milk and the extracts, then pour over the cooled cake and sprinkle with additional coconut flakes.

Hint: Do not let the cake remain in the bundt pan for more than 10 minutes after baking. Leaving it longer increases the risk it will stick to the pan.

Recipe variations and substitute ideas

• Sour Cream: Replace buttermilk with a mixture of sour cream and whole milk for a richer crumb.
• All-Purpose Flour: If you don’t have cake flour, sifted all-purpose flour will work—expect a slightly denser texture.
• Vegetable Shortening: Can be used instead of butter for a different texture.
• Pecans: Stir chopped pecans into the coconut topping or sprinkle them on top for extra crunch.
• Lemon Glaze: Swap evaporated milk for lemon juice or add lemon extract to the glaze for a bright, tangy finish.

Necessary gear: Equipment

A 9″ bundt pan (or tube pan) gives this cake its classic shape. If you don’t have a bundt pan, two 9″ round cake pans will work—bake until a skewer comes out mostly clean. A stand mixer speeds the process, but a hand mixer or a sturdy whisk will also do the job.

How to store leftovers

Store slices in an airtight container at room temperature for up to five days. If your kitchen is humid, tuck a piece of paper towel under the lid to absorb excess moisture. Refrigeration will extend freshness if you prefer a chilled cake.

More recipes you might enjoy

If you love classic Southern desserts, consider trying pecan pie, pumpkin pie, apple pie, or pineapple upside-down cake—each brings its own comforting flavor and pairs beautifully with coffee or tea.

Kitchen notes

Grease and flour the bundt pan right before you add the batter to avoid sliding and pooling. Getting butter into every groove helps the cake release cleanly and preserves the crunchy topping.
