Ingredients for america's test kitchen coffee cake
Twelve simple ingredients create America's Test Kitchen's signature coffee cake: moist layers with buttery streusel.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 2 ½ cups | Sifted for even texture |
| Cake Flour 🌾 | ½ cup | For tender crumb structure |
| Granulated Sugar 🍚 | 1 ½ cups | White sugar preferred |
| Light Brown Sugar 🍚 | ½ cup | Packed firmly |
| Unsalted Butter 🧈 | 1 cup | Cold, cubed for streusel |
| Large Eggs 🥚 | 2 whole | Room temperature |
| Pure Vanilla Extract 🌿 | 2 tbsp | High-quality preferred |
| Milk 🥛 | 1 cup | Whole milk preferred |
| Baking Powder 🧂 | 2 tsp | Aluminum-free recommended |
| Salt 🧂 | ½ tsp | Diamond Crystal preferred |
| Vanilla Bean Paste 🌿 | 1 tbsp | For enhanced vanilla flavor |
| Old-Fashioned Rolled Oats 🍞 | ½ cup | Blended into fine crumbs |
The flour blend is critical—all-purpose flour provides structure while cake flour ensures tenderness. For the best results, sift both together before mixing. King Arthur or Bob's Red Mill flours work exceptionally well. The vanilla bean paste elevates the flavor beyond standard extract, though pure extract works in a pinch. When measuring sugars, pack the brown sugar firmly into the cup for accurate sweetness. For the streusel, cold butter is non-negotiable—it creates the perfect crumbly texture without melting prematurely.
No cake flour? Substitute with all-purpose flour by reducing by 2 tablespoons per cup (use 0.45 cups all-purpose instead of 0.5 cups cake flour). Short on vanilla bean paste? Double the pure vanilla extract—though the flavor won't be identical. The rolled oats can be replaced with quick oats if needed, but they won't blend as smoothly. For a richer streusel, add 1 tablespoon chopped pecans or white chocolate chips. If your recipe calls for buttermilk, combine 1 cup milk with 1 tablespoon lemon juice or vinegar and let sit for 5 minutes.
Store the cake in an airtight container at room temperature for up to 3 days—though it's best enjoyed fresh. For longer storage, wrap tightly in plastic wrap and refrigerate for up to 5 days. The streusel topping stays crisp for 2 days at room temperature but softens when refrigerated. Freeze portions in single-serving slices for up to 3 months. Reheat slices in the oven at 350°F for 5-7 minutes to restore crispness.
Why You'll Love This Recipe
- No-Mix Madness: I swear by this recipe because it’s the only coffee cake I’ve ever made that doesn’t require creaming butter and sugar by hand. Just toss everything in a bowl—flour, sugars, melted butter—and stir until just combined. That two-flour combo (all-purpose + cake flour) gives it the perfect crumb without fuss.
- Butter-Sugar Magic: The secret’s in the brown sugar and butter. That light brown sugar keeps it moist, while the cold butter cubes create pockets of flaky, golden streaks. Honestly, the first bite makes me question why I ever bought boxed mixes.
- Weeknight Hero: Between us, this is my go-to for breakfast meetings, book club brunches, or when I need to feed the kids something that doesn’t involve cereal. Slice it warm, or pack leftovers for days—it’s that reliable.
- Budget Breakthrough: I use store-brand butter and sugar, and this recipe stretches to feed six for under $3. The cake flour is the only splurge, but one bag lasts forever. Plus, it’s the kind of dessert that makes you feel fancy without breaking the bank.
Step-by-step instructions for streusel-topped vanilla coffee cake
Precision baking delivers the perfect balance of tender crumb and buttery streusel. Here's how to nail it.
👨🍳 Step 1: Prepare the Dry and Wet Ingredients Separately
In a large bowl, whisk together the 2.5 cups all-purpose flour, 0.5 cup cake flour, 2 teaspoons baking powder, and 0.5 teaspoon salt. Sift the mixture twice through a fine-mesh sieve to ensure an even texture and prevent dense spots. Set aside.
In a separate medium bowl, combine the 1.5 cups granulated sugar, 0.5 cup packed light brown sugar, 2 whole large eggs, 2 tablespoons pure vanilla extract, and 1 tablespoon vanilla bean paste. Whisk vigorously for 2 minutes until the mixture lightens noticeably and triples in volume. This thorough mixing incorporates air, creating that signature tender crumb.
🍳 Step 2: Combine Wet and Dry Ingredients for the Cake Base
Gradually add the dry ingredients to the wet mixture in three additions, mixing just until combined after each addition. Avoid overmixing—you should still see small flour streaks. Pour in the 1 cup whole milk and stir until just incorporated.
For the vanilla swirl, divide the batter evenly between two 9-inch round cake pans lined with parchment paper. Using an offset spatula, create a well in the center of each pan. Spoon 1 tablespoon vanilla bean paste into each well and gently swirl it into the batter using the spatula tip. This creates those beautiful marbled vanilla streaks throughout.
👨🍳 Step 3: Make the Streusel Topping
In a food processor, pulse the 0.5 cup old-fashioned rolled oats until they resemble fine crumbs. Transfer to a medium bowl and add the 1 cup cold cubed unsalted butter, 0.25 cup granulated sugar, and 0.25 cup packed light brown sugar. Use a pastry cutter or your fingers to work the butter into the oat mixture until it resembles coarse crumbs with pea-sized butter pieces.
This texture is crucial—the streusel should be crumbly but still hold together when sprinkled. If it feels too dry, add 1 teaspoon milk and mix. The streusel should be moist enough to stick to your fingers slightly but not form a paste.
🥘 Step 4: Assemble and Bake for Perfect Texture
Preheat your oven to 350°F. Evenly divide the streusel topping between the two prepared cake pans, sprinkling it generously over the vanilla-swirled batter. Gently press down with your fingertips to ensure even distribution and better contact with the cake.
Bake for 30-35 minutes, rotating the pans halfway through, until a toothpick inserted into the center comes out clean and the edges are deep golden brown. The cake should spring back slightly when pressed gently. Here's the thing—don't open the oven door during baking. The sudden temperature change can cause the cake to sink in the middle.
⏰ Step 5: Cool and Serve for Maximum Moisture
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. This gradual cooling prevents the streusel from becoming soggy while allowing the cake to set properly.
For serving, slice with a serrated knife while still slightly warm. The ideal slice should have a moist, tender crumb with pockets of vanilla flavor, topped by a crispy yet crumbly streusel that doesn't turn to mush. Store any leftovers in an airtight container at room temperature for up to 3 days or freeze for up to 3 months for maximum freshness.
Pro Tips For Making America'S Test Kitchen Coffee Cake
- MIX DRY INGREDIENTS FIRST: The ATK recipe splits the dry ingredients into two batches—don’t skip this. Sifting the cake flour (for the streusel) separately from the all-purpose flour (for the cake) guarantees a lighter, less dense crumb. I used to toss them together, and the texture always felt heavier afterward.
- USE COLD BUTTER FOR STREUSEL: The streusel’s magic lies in its texture, and cold butter is non-negotiable. Cut the butter into the brown sugar and flour mixture in small cubes—no need to fully incorporate—so you end up with pea-sized, buttery pockets. Warm butter = greasy streusel that clumps instead of crisping.
- STOP WHEN CENTER’S JUST SET: Overbaking is the silent killer of coffee cake. The ATK recipe calls for an internal temp of 190–195°F, but pull it out when the edges are golden and the center springs back very slowly to gentle pressure. A toothpick with a few moist crumbs is fine—dry means it’s tough.
- SWAP BUTTER FOR BROWN SUGAR: If you’re fresh out of brown sugar but still want that deep caramel flavor, replace it 1:1 with molasses. Yes, it’s stronger, so cut the amount in half—use ¼ cup molasses per ½ cup called for. The streusel will be richer, and the cake’s crumb stays tender. (I tested this after burning through my last bag of brown sugar.)
Serving suggestions for this dish
Morning Coffee Pairings
This coffee cake pairs beautifully with a medium-roast dark coffee like Starbucks Sumatra or Peet's Major Dickason's Blend—their deep, caramel notes complement the cake's vanilla swirls without overpowering. For a lighter option, try Green Mountain Coffee Roasters Breakfast Blend with its bright acidity.
I always keep a French press on hand for freshly brewed coffee that enhances the cake's buttery richness. ☕
Creamy Toppings
Warm vanilla bean ice cream or whipped cream takes this coffee cake to the next level. For a lighter option, drizzle with honey or maple syrup—about 1 tablespoon per slice—to balance the streusel's sweetness.
If you prefer something more indulgent, a dollop of salted caramel sauce adds a sophisticated touch. I often serve it with a small scoop of salted caramel gelato for contrast. 🍯
Seasonal Fruit Additions
In summer, top slices with sliced peaches or berries for freshness. For autumn, try candied pecans or spiced apples—toss ½ cup diced apples with 1 teaspoon cinnamon and 1 tablespoon brown sugar before sprinkling.
Winter calls for warm spiced compote: simmer 1 cup cranberries with 2 tablespoons orange juice and 1 teaspoon ginger for 5 minutes until thickened. 🍎
Beverage Pairings Beyond Coffee
For a non-coffee twist, pair with chai tea or hot chocolate. A strong chai latte from Tazo enhances the cake's vanilla flavors, while dark chocolate (70% or higher) provides a rich contrast. For a refreshing option, try iced vanilla chai in summer—it mirrors the cake's vanilla swirls beautifully. 🍫
Presentation Tips
Slice the cake with a serrated knife while slightly warm for clean edges. Serve on a wooden board or white porcelain plate to highlight the golden streusel.
Garnish with crushed pistachios or toasted coconut flakes for added texture. For a rustic touch, dust with powdered sugar or cocoa powder before serving. ✨

Frequently asked questions
Can I make this coffee cake in a bundt pan instead of round pans?
The recipe is designed for two 9-inch round pans, but you can adapt it to a 10-12 cup bundt pan by reducing the batter by about 20%. For best results, use a bundt pan with a removable center tube to ensure even baking. The streusel topping may need to be adjusted to 3/4 cup total and pressed more firmly to prevent sliding during baking.
Why does my coffee cake turn out dense instead of tender?
Overmixing the batter is the most common culprit—stop mixing as soon as the dry ingredients disappear. Another issue could be using too much flour or not sifting properly. Also ensure your butter is cold for the streusel and your eggs are room temperature. If the cake still feels dense, try adding 1 extra tablespoon of milk to the batter for moisture.
How can I make this recipe gluten-free?
Replace the all-purpose and cake flour blend with a 1:1 gluten-free baking flour (like Bob's Red Mill or King Arthur) plus 1 teaspoon xanthan gum. For the streusel, use gluten-free rolled oats (certified). The texture will be slightly different but still delicious. Expect the cake to be more delicate—bake for 5-7 minutes less and check for doneness early.
Can I make this coffee cake ahead of time?
Bake the cake 1 day ahead and store it in an airtight container at room temperature. The streusel stays crisp for 2 days, but the cake's moisture remains perfect. For longer storage, freeze slices wrapped individually for up to 3 months. To revive, warm frozen slices at 350°F for 5 minutes before serving.
What's the secret to getting that perfect streusel crunch?
Cold butter is non-negotiable—it creates the right texture. Work the butter into the oats until you have pea-sized pieces, not a paste. For extra crunch, add 1 tablespoon cornstarch to the streusel mixture. Press it firmly into the cake before baking, and avoid opening the oven door during the first 25 minutes of baking to prevent sogginess.
