Ingredients for america's test kitchen coconut cake
Twelve ingredients, zero shortcutsāthis is how you get bakery-style coconut cake at home.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour š¾ | 2 Ā½ cups | Sifted for light texture |
| Granulated Sugar š | 1 Ā½ cups | White or light brown |
| Unsalted Butter š§ | 1 cup | Cold, cubed for creaming |
| Large Eggs š„ | 3 whole | Room temperature |
| Buttermilk š„ | 1 cup | Cold for best results |
| Vanilla Extract šø | 2 tsp | Pure, high-quality |
| Baking Powder š§ | 2 tsp | Aluminum-free preferred |
| Salt š§ | Ā½ tsp | Fine sea salt |
| Shredded Unsweetened Coconut š„„ | 1 Ā½ cups | Freshly toasted |
| Coconut Extract š„„ | 1 tsp | Pure, high-quality |
| Simple Syrup šÆ | Ā½ cup | 1:1 sugar to water ratio |
| Powdered Sugar š | 1 cup | For dusting |
The butter is non-negotiable hereāit needs to be cold and cubed for that perfect creaming with the sugar. Land OāLakes unsalted sticks are my go-to, but any high-fat butter (80%+ fat content) works. The coconut? Freshly toasted is key for that signature crunchāno pre-shredded stuff from the can. For the extract, Goya or McCormick are reliable brands, but if youāve got homemade, even better. The buttermilk should be coldāroom temperature makes for a denser crumb. And that simple syrup? Make it freshāstore-bought versions have preservatives that can alter the texture.
No buttermilk? Substitute with 1 cup milk + 1 tbsp vinegar or lemon juice, let it sit 5 minutes. Short on coconut extract? Vanilla extract at half the amount works in a pinch, though the flavor will be subtly different. The baking powder must be freshāif itās older than 6 months, toss it. For the powdered sugar glaze, Domino or C&H brands sift beautifully. Pro tip: Toast the coconut in a dry skillet over medium heat for 5-7 minutes until goldenādonāt walk away, or itāll burn. The smell alone is worth it.
Store the cake in an airtight container at room temperature for up to 3 daysāit actually improves overnight as the flavors meld. For longer storage, wrap tightly in plastic and refrigerate for up to 1 week. Freeze the glaze separately if youāre prepping aheadājust reheat the syrup gently before dusting. The toasted coconut topping stays crisp for 2 days if kept in a sealed container. And if youāre feeling fancy, serve with a scoop of coconut ice creamātrust me on this.
Why You'll Love This Recipe
- No Mixer Needed: This recipe relies on the creaming methodājust butter and sugar with a hand mixer (or even a sturdy whisk if you're feeling old-school). No stand mixer? No problem. The buttermilk keeps things tender without overworking the batter, so you can focus on other things while it comes together.
- Tropical Magic: That first bite of moist coconut cake with the buttery crumb? Itās like a hug in dessert form. The sugar and eggs create a rich, velvety texture, while the toasted coconut on top adds a caramelized crunch thatās impossible to resistāno artificial flavors here, just pure, simple indulgence.
- Weeknight Hero: Between us, this is the cake I turn to when I need something impressive but not labor-intensive. Itās perfect for birthdays, potlucks, or just becauseāno one will guess it took less than an hour from start to finish. And the leftovers? Theyāre just as good the next day, sliced and warmed with a sprinkle of toasted coconut.
- Budget-Friendly Luxury: Youāre using pantry staplesāflour, sugar, butterāthat you already own, plus a few eggs and buttermilk. The result? A cake that tastes like it cost twice as much. Honestly, Iāve made this for dinner parties and family gatherings, and no one ever asks for the recipe because they assume itās from a fancy bakery. (Spoiler: Itās not.)
Step-by-step instructions for america's test kitchen coconut cake
Here's how to create a perfectly moist coconut cake with that signature toasted crunch.
šØāš³ Step 1: Toast the Coconut for Maximum Flavor
Preheat your oven to 325Ā°F and spread the 1.5 cups shredded unsweetened coconut on a rimmed baking sheet. Toast for 8-10 minutes until the coconut turns a beautiful golden brown and releases an intoxicating aroma. Stir it halfway through for even toastingāyou want it fragrant and slightly crispy, not burned. Let it cool completely before using, as the residual heat will melt the butter in your cake batter.
This toasting step is non-negotiable for authentic coconut flavor. I've found that freshly toasted coconut makes all the difference in texture and aroma compared to store-bought versions. Keep an eye on it after the 8-minute markācoconut burns quickly once it starts to darken.
š³ Step 2: Cream Butter and Sugars to Light and Fluffy
In a stand mixer fitted with the paddle attachment, beat the 1 cup cold cubed unsalted butter with the 1.5 cups granulated sugar on medium speed for 3-4 minutes. You're looking for a pale, fluffy mixture that nearly doubles in volume. This creaming process incorporates air, which creates that signature tender crumb.
I like to keep the butter cold at first to prevent over-creaming. After about 2 minutes, the mixture will start to lighten noticeably. If it starts to look too warm or melty, chill the bowl in the freezer for 5 minutes to reset the texture. The butter should hold its shape when pressed but still be soft enough to beat.
šØāš³ Step 3: Build the Batter with Wet and Dry Ingredients
Add the 3 whole room temperature large eggs one at a time, mixing on low speed after each addition until fully incorporated. Then add the 2 tsp vanilla extract and 1 tsp coconut extract, mixing for 30 seconds to combine. In a separate bowl, whisk together the 2.5 cups sifted all-purpose flour, 2 tsp baking powder, and 0.5 tsp salt.
With the mixer on low speed, gradually add the dry ingredients to the wet mixture. Mix just until combinedāyou should still see a few flour streaks. Overmixing develops gluten and can make your cake dense. Then gently fold in the cooled toasted coconut using a silicone spatula. The batter will be thick and richāthis is exactly what you want for that ultra-moist texture.
š„ Step 4: Layer and Bake for Perfect Rise
Pour half of the batter into two 8-inch round cake pans lined with parchment paper. Divide the 0.5 cup simple syrup evenly between the layers and pour over the batter. Top with the remaining batter. Smooth the tops with a spatula and bake at 350Ā°F for 25-30 minutes, until a toothpick inserted in the center comes out clean.
I find the simple syrup step crucial for moistureāit keeps the cake tender and adds subtle sweetness. Don't overbake! The cake will continue cooking as it cools. If the tops brown too quickly, tent with foil after 20 minutes. The edges should pull away slightly from the pan, and the cake should spring back when gently pressed in the center.
š° Step 5: Cool and Dust with Powdered Sugar
Remove the cakes from the oven and let them cool in the pans for 10 minutes. Then transfer to a wire rack to cool completely. Once completely cool, dust the tops generously with the 1 cup powdered sugar using a fine-mesh sieve. This creates that signature dusted look while keeping the cake light.
For the best results, let the cakes cool completely before slicing. The contrast between the moist crumb and toasted coconut will be most pronounced when served at room temperature. I like to serve this cake with a dollop of whipped cream or a scoop of coconut ice cream for extra indulgence.
Pro Tips For Making America'S Test Kitchen Coconut Cake
- MEASURE FLOUR BY WEIGHING: I learned this the hard wayāspooning flour into cups packs it too tightly, making your cake denser than the recipe intended. Use a kitchen scale for the 2 1/4 cups all-purpose flour; 250 grams is your target. No scale? Spoon into the cup and level with a knifeādonāt press down.
- CREAM BUTTER AND SUGAR UNTIL PALE: This isnāt just mixingāyour butter should look like wet sand, not butter. Use a stand mixer with the paddle attachment and cream for 3ā5 minutes until the color lightens noticeably. Stopping too soon means underdeveloped gluten, which leads to a cake that collapses faster than your willpower on a diet.
- DONāT OVERMIX THE BATTER: Once you fold in the buttermilk and coconut, mix just until combinedāabout 10 strokes with a spatula. I used to think more mixing = better texture, but this recipe relies on tender layers. Overmixing develops gluten, and your cake will turn out tougher than a two-day-old loaf of bread.
- LET THE BATTER REST 10 MINUTES: This is the thing that matters most after mixing. After adding the coconut, let the batter sit while you preheat the oven. The flour absorbs moisture, and the eggs relax, giving you a lighter crumb. I know, I knowāyouāre eager to bake. But skip this, and youāll regret it when your cakeās texture is more brick than sponge.
Regional styles of this recipe
Hawaiian Luau Twist
Transform this cake into a true Hawaiian experience by adding Ā½ cup macadamia nuts (finely chopped) to the batter alongside the toasted coconut. Top with a Ā½ cup pineapple jam (warmed slightly) drizzled between layers, then finish with extra toasted coconut and macadamia nuts.
Serve with a scoop of coconut-macadamia ice cream for that island vibe. šŗ
Caribbean Rum Version
For a boozy Caribbean flair, replace Ā½ cup of the simple syrup with Ā½ cup dark rum (like Appleton Estate or Bacardi 8-year). Brush the warm cake layers with this rum syrup before assembling, then dust with powdered sugar.
Garnish with lime zest and extra toasted coconut. Pair with a rum-spiked coconut cream sauce for dipping. š¹
Southern Cream Cheese Swirl
Give it a Southern twist by adding 8 oz cream cheese (softened) to the batter after mixing in the wet ingredients. Fold in Ā½ cup powdered sugar and swirl it through the batter before baking.
Top with a Ā½ cup cream cheese frosting (mix 4 oz cream cheese, 2 tbsp butter, and 1 cup powdered sugar) and toasted coconut. This adds a rich, tangy contrast that Southern bakers will love. š°
Vegan Adaptation
For a plant-based version, swap the butter for 1 cup vegan butter (like Miyoko's), buttermilk for 1 cup almond milk + 1 tbsp apple cider vinegar, and eggs for 3 flax eggs (3 tbsp ground flaxseed + 9 tbsp water).
Use coconut oil instead of butter for the simple syrup. The coconut flavor shines even brighter without dairy, and the texture remains ultra-moist. š±
Gluten-Free Option
Replace the all-purpose flour with a 1:1 gluten-free baking flour (like Bob's Red Mill GF 1-to-1). Add Ā½ tsp xanthan gum to help bind the batter. Use a 9-inch round pan instead of 8-inch to account for potential volume loss.
The cake will still be tender, though slightly denserāperfect for those with gluten sensitivities. š„„

Frequently asked questions
Why does this coconut cake recipe use both shredded coconut and coconut extract?
The shredded coconut provides that essential toasted crunch topping, while the coconut extract enhances the flavor throughout the moist layers. The extract ensures every bite has coconut essence without overpowering, while the toasted coconut adds texture contrast. This two-part approach creates a more complex, bakery-style experience than using just one.
Can I make this cake in a single 9-inch pan instead of two 8-inch pans?
Yes, but with adjustments! Reduce baking time to 20-25 minutes and use a 9x2-inch round pan. The cake will be slightly taller and denser, but still delicious. For best results, bake at 325Ā°F instead of 350Ā°F to prevent over-browning. The simple syrup layer is still crucial for moisture.
What's the secret to keeping this coconut cake moist for days?
The simple syrup between layers and the buttermilk in the batter are the game-changers. The syrup adds moisture while baking, and the buttermilk creates a tender crumb. Store in an airtight container at room temperature for up to 3 daysāit actually improves overnight! For longer storage, refrigerate and bring to room temperature before serving.
How do I fix a coconut cake that's too dense?
Density usually means overmixing or using warm butter. For next time, mix dry ingredients just until combined (a few flour streaks should remain) and keep butter cold until the mixture lightens. If you've already baked it, try slicing thinly and serving with whipped creamāthis adds airiness to compensate. The toasted coconut topping helps balance any denseness.
Can I substitute regular milk for the buttermilk?
Yes, but you'll need to make a quick substitute: mix 1 cup milk + 1 tablespoon vinegar or lemon juice, then let it sit for 5 minutes to curdle. This mimics buttermilk's acidity, which helps tenderize the cake. Don't skip the waiting timeārushing will leave your cake denser. The flavor difference is minimal but noticeable.
