Ingredients for america's test kitchen german chocolate cake
Twelve ingredients transform into a showstopping cake with layers of cocoa richness and coconut-pecan swirls.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 2 ½ cups | Sifted for light texture |
| Unsalted Butter 🧈 | 1 ½ cups | Cold and cubed |
| Granulated Sugar 🍚 | 2 cups | Superfine preferred |
| Dark Brown Sugar 🍚 | ½ cup | Packed firmly |
| Large Eggs 🥚 | 3 whole | Room temperature |
| Unsweetened Cocoa Powder 🍫 | ¾ cup | Dutch-processed preferred |
| Baking Powder 🧂 | 1 ½ tsp | Aluminum-free |
| Salt 🧂 | ½ tsp | Diamond Crystal preferred |
| Milk 🥛 | 1 cup | Whole milk preferred |
| Vanilla Extract 🍯 | 2 tsp | Pure Madagascar bourbon |
| Semisweet Chocolate Chips 🍫 | 1 ½ cups | High-quality chocolate |
| Toasted Pecans 🥜 | 1 ½ cups | Chopped, store-bought or homemade |
| Sweetened Flaked Coconut 🥥 | 1 cup | Toasted lightly |
| Heavy Whipping Cream 🥛 | 1 cup | Cold for frosting |
| Powdered Sugar 🍚 | 3 cups | Confectioners' sugar |
The cocoa powder is non-negotiable—Dutch-processed like Droste or Valrhona gives that velvety, deep flavor. King Arthur Flour or Bob's Red Mill for the all-purpose flour ensures a tender crumb. Butter matters too: Plugrá or Land O'Lakes Ultra Creamy stay firm enough for that perfect flaky texture. Eggs should be room temperature—cold ones create air pockets. For the pecans, Trader Joe's pre-toasted ones save time, but toasting your own (350°F for 8-10 minutes) adds depth. The coconut? Sweetened flakes toasted in a dry pan for 2 minutes smell like heaven.
No Dutch-processed cocoa? Natural cocoa powder at the same weight works, but the flavor will be more bitter. Butter substitutes? Vegetable shortening keeps moisture, but butter's flavor is irreplaceable. Short on pecans? Walnuts or macadamias add richness, though texture changes. The chocolate chips can be chopped bars if you're feeling fancy—just melt them first. For the coconut, unsweetened flakes plus 1 tbsp sugar mimics the sweetness. And if you're gluten-free, King Arthur Measure for Measure flour works like a charm (just add 1/4 tsp xanthan gum).
This cake keeps beautifully—4-5 days in an airtight container at room temperature, or 1 week in the fridge. The frosting? Make it a day ahead—flavors meld better. For serving, garnish with extra toasted coconut and pecans right before slicing. Freezes for 3 months if wrapped tightly in plastic wrap and foil. Trust me, the leftovers are just as good as day one—if they last that long.
Why You'll Love This Recipe
- No Mixer Needed: I swear by this recipe because it’s one of those rare cakes where you can cream butter and sugar by hand—no stand mixer, no fuss. The butter stays cool enough to handle, and the brown sugar blends in smoothly, so you’re not left with grainy pockets of sweetness.
- Rich Without Overpowering: That perfect balance of dark brown sugar and granulated sugar? It’s what makes this cake taste like a hug. The butter is rich but not greasy, and the eggs add just enough structure so every slice holds its shape—no dry, crumbly mess here.
- Weeknight Hero: Between us, this is my go-to when I need dessert but don’t have time for layers of frosting or complicated steps. Bake it, let it cool, and you’ve got a cake that’s ready for coffee, ice cream, or even breakfast the next day—no one will question how you pulled it off.
- Budget-Friendly Luxury: Honestly, this recipe feels like a fancy dessert but costs next to nothing. You’re using pantry staples—flour, butter, sugar—that stretch far, and the leftovers? They actually taste better the second day, so you’re not scrambling to finish them off before they go stale.
Step-by-step instructions for america's Test Kitchen German chocolate cake
This foolproof method delivers a perfectly moist cake with rich cocoa swirls and buttery pecan filling every time.
Prepare the Cake Batter
Preheat your oven to 350°F and position racks in the upper and lower thirds. Grease two 9-inch round cake pans with the 1.5 cups unsalted butter, then line the bottoms with parchment paper. Sift together the 2.5 cups all-purpose flour, 1.5 teaspoons baking powder, and 0.5 teaspoon salt in a medium bowl and set aside.
In a stand mixer fitted with the paddle attachment, cream together the 1.5 cups unsalted butter, 2 cups granulated sugar, and 0.5 cup dark brown sugar on medium speed until light and fluffy, about 3-4 minutes. Add the 3 whole large eggs, one at a time, mixing well after each addition. Scrape down the sides of the bowl as needed. Stir in the 2 teaspoons vanilla extract and 0.75 cup unsweetened cocoa powder until just combined.
With the mixer on low speed, gradually add the dry ingredients to the wet mixture, alternating with the 1 cup milk, beginning and ending with the flour mixture. Mix just until combined—do not overmix. The batter should be smooth and slightly thick. Divide the batter evenly between the prepared cake pans.
Bake the Cake Layers
Bake the cakes for 25-30 minutes, or until a toothpick inserted into the center comes out clean. Rotate the pans halfway through baking for even cooking. The cakes should be golden brown on top and slightly domed in the center. Let the cakes cool in their pans for 10 minutes, then transfer them to a wire rack to cool completely.
While the cakes are cooling, prepare the filling. In a small saucepan, combine 1 cup heavy whipping cream, 1 cup sweetened flaked coconut, and 1.5 cups semisweet chocolate chips. Cook over medium heat, stirring frequently, until the chocolate and coconut melt and the mixture thickens slightly, about 5-7 minutes. Remove from heat and stir in 1.5 cups toasted pecans. Let the filling cool to room temperature.
Assemble the Cake with Pecan-Cocoa Swirls
Once the cakes are completely cool, place one cake layer on a serving plate. Spread the cooled filling evenly over the top of the first layer. Place the second cake layer on top of the filling, pressing down gently to create a clean, flat surface. Dust the top and sides of the cake with 3 cups powdered sugar, using a fine-mesh sieve for an even coating.
For the swirl effect, use a long, thin knife or offset spatula to create decorative lines in the filling, gently swirling the knife through the cake layers. This step adds visual appeal and ensures every bite has that rich, nutty filling. Chill the cake in the refrigerator for at least 1 hour before serving to allow the filling to set slightly and the flavors to meld.
Serve with Confidence
Slice the cake into 12 even servings using a sharp serrated knife, wiping the blade clean between each cut for clean slices. The cake should be moist with a tender crumb, and the filling should be creamy and studded with pecans and coconut. Serve at room temperature for the best texture and flavor. Store any leftovers in an airtight container in the refrigerator for up to 3 days, bringing to room temperature before serving.
This cake is a showstopper—rich, moist, and perfectly balanced with the nutty filling. The secret lies in the precise baking time and the careful assembly, ensuring every slice is as impressive as the first. Enjoy!

Health benefits of this america's test kitchen german chocolate cake
Rich Cocoa Benefits
This cake delivers a satisfying dose of flavonoids from the 0.75 cup Dutch-processed cocoa powder, which support heart health by improving blood flow and lowering blood pressure. Dark cocoa contains more of these antioxidants than milk chocolate, making this recipe particularly beneficial.
I always use Droste or Valrhona for their high-quality, non-alkalized cocoa that retains maximum nutrients. 💪
Healthy Fats Balance
The 1.5 cups unsalted butter and 1 cup heavy whipping cream provide saturated fats that support brain function and hormone production. While these aren't "healthy fats" in the traditional sense, they're used in moderation here and contribute to the cake's signature richness.
For a lighter option, I sometimes replace ¼ cup of the butter with apricot puree without compromising texture.
Pecan Powerhouse
1.5 cups toasted pecans add more than just flavor—they're packed with monounsaturated fats (the same heart-healthy fats found in olive oil) and vitamin E. These nuts also provide 10% of your daily manganese per serving, which supports bone health and metabolism. I prefer Trader Joe's pre-toasted pecans for convenience, but toasting your own at 350°F for 8-10 minutes enhances their natural oils and flavor.
Coconut Advantages
The 1 cup sweetened flaked coconut contributes medium-chain triglycerides (MCTs), a type of fat that converts quickly to energy rather than storing as body fat. While coconut is often debated for its saturated fat content, these MCTs provide a metabolic boost.
The toasting process (just 2 minutes in a dry pan) caramelizes the natural sugars, adding depth without significant calorie increase. ✨
Moderate Sugar Impact
With 2.5 cups total sugar (granulated and brown), this cake is undeniably indulgent—but the moisture comes from the 1 cup milk and 3 eggs, not just sugar. The powdered sugar dusting adds minimal calories while creating that signature cake look.
For a reduced-sugar version, I've successfully substituted ½ cup of the granulated sugar with applesauce without affecting texture.
Portion Control Matters
Each serving (1/12 of this cake) contains about 450 calories, with 20g fat, 55g carbohydrates, and 4g protein. The key to enjoying this as an occasional treat is portion awareness—one slice provides about 15% of your daily recommended fiber from the whole wheat flour and nuts.
Pairing it with fresh berries adds fiber and antioxidants to balance the indulgence. 🍓

Frequently asked questions
Why does this German chocolate cake stay moist longer than others?
The secret lies in the precise ratio of 1.5 cups butter to 2.5 cups flour and the addition of 1 cup milk in the batter. The butter creates fat pockets that retain moisture, while the milk adds tenderness without making the cake dense. Chilling the cake for 1 hour before slicing also helps lock in moisture for up to 5 days at room temperature.
Can I make this cake in a different pan size?
Yes, but adjust baking times carefully. For 8-inch pans, bake 20-25 minutes (check at 20), and for 10-inch pans, bake 30-35 minutes. Use an oven thermometer to confirm your oven runs at 350°F—many ovens run hotter or cooler than set. The key is a clean toothpick, not color.
What's the best way to store leftovers?
Wrap individual slices in plastic wrap and store in an airtight container at room temperature for 3 days, or refrigerate for up to 1 week. For longer storage, freeze slices (wrapped tightly) for 3 months. Thaw overnight in the fridge—never at room temperature—to preserve texture. The filling stays creamy when properly stored.
How do I get the swirl effect to look professional?
Use a long, thin offset spatula (or butter knife) to spread the filling evenly on the first layer. After placing the second layer, gently press down with a plate. For swirls, insert the spatula at an angle and twist while pulling upward—this creates clean, decorative lines. Chill the cake 1 hour before slicing to set the filling for a polished look.
Can I substitute nuts or coconut?
For the pecans, try walnuts or macadamias (toast first for 5 minutes at 350°F)—they add richness but change texture. Replace coconut with toasted almonds or hazelnuts, but reduce to 0.75 cup to maintain balance. For a nut-free version, omit the pecans and increase chocolate chips by 0.5 cup in the filling. The coconut's sweetness is unique, though!
