Ingredients for america's test kitchen coffee cake
Precision and layering create this America's Test Kitchen coffee cake with irresistible texture and lasting moisture.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 2 ½ cups | Sifted for even texture |
| Granulated Sugar 🍚 | 1 ½ cups | White or light brown |
| Packed Brown Sugar 🍚 | ½ cup | Light or dark variety |
| Unsalted Butter 🧈 | 1 cup | Cold, cubed for streusel |
| Large Eggs 🥚 | 2 whole | Room temperature |
| Pure Vanilla Extract 🍯 | 1 ½ tbsp | High-quality preferred |
| Milk 🥛 | 1 cup | Whole milk preferred |
| Baking Powder 🧂 | 2 tsp | Diamond Crystal preferred |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Old-Fashioned Rolled Oats 🍚 | ½ cup | Not quick oats |
| Cinnamon 🌿 | 1 tsp | Ground preferred |
| Vanilla Bean Seeds 🍯 | 1 tsp | Scraped from 1 bean |
| Toasted Walnuts 🥜 | ¼ cup | Chopped, optional |
The flour and sugars form the foundation—use King Arthur or Gold Medal for reliable texture. Brown sugar adds moisture, while granulated ensures proper structure. Unsalted butter is critical for flavor; don't substitute margarine. For the streusel, cold cubed butter creates optimal crumb. Whole milk enhances richness, and Diamond Crystal baking powder provides lift without bitterness. The vanilla extract should be pure—Nielsen-Massey is a reliable brand for professional results.
No vanilla extract? Vanilla bean seeds plus 1 tbsp sugar mimic the depth. Substitute milk with evaporated milk or buttermilk for tang. The oats must be old-fashioned—quick oats create gummy streusel. For nut-free, omit walnuts or use chopped pecans. Pre-measure everything for precision—this recipe demands it. Room-temperature eggs blend smoothly; cold eggs cause streaks. The cinnamon should be fresh—ground spices lose potency after 6 months. For extra moisture, add 1 tbsp sour cream to the batter.
Store wrapped at room temperature for 3 days or refrigerate for 1 week—the streusel stays crisp. Reheat slices at 350°F for 5 minutes to restore freshness. Freeze portions for 3 months by wrapping tightly. The cake improves overnight as flavors meld. Butter-wrapped slices reheat beautifully in the toaster. For brunch crowds, bake in a 9x13-inch pan—this recipe scales perfectly.

Step-by-step instructions for america's Test Kitchen coffee cake recipe
Master the science behind a coffee cake that stays moist for days with this precise method.
Prepare the Cake Batter for Perfect Texture
In a large mixing bowl, whisk together the 2.5 cups all-purpose flour, 2 tsp baking powder, and 0.5 tsp salt. Sift the dry ingredients to eliminate lumps and ensure even distribution throughout the batter. This step is crucial for a tender crumb that stays moist longer.
In a separate bowl, beat the 1 cup unsalted butter and 1.5 cups granulated sugar together until light and fluffy—this should take about 3-4 minutes using an electric mixer. The butter should become pale in color, indicating proper aeration. Add the 2 whole large eggs, one at a time, mixing well after each addition. Incorporate the 1.5 tbsp pure vanilla extract and 1 tsp vanilla bean seeds, scraping down the sides of the bowl as needed.
Gradually add the 1 cup milk to the butter mixture while mixing on low speed, then alternate adding the dry ingredients and the 0.5 cup packed brown sugar in three parts. Mix just until combined—overmixing develops gluten, which can make the cake dense. The batter should be smooth and slightly thick, with no visible flour streaks.
Create the Streusel Topping for Crispy Contrast
In a medium bowl, combine the 0.5 cup old-fashioned rolled oats, 1 tsp cinnamon, and 0.25 cup toasted walnuts. Cut the 1 cup unsalted butter (cold and cubed) into the dry ingredients using a pastry cutter or your fingers until the mixture resembles coarse crumbs with pea-sized butter pieces. This texture is key for a streusel that stays crunchy on top while keeping the cake moist below.
Add the 0.5 cup packed brown sugar and mix until evenly distributed. The streusel should hold its shape when pressed gently but still feel slightly crumbly. If it sticks together too much, chill the mixture for 10-15 minutes to firm up the butter. This step ensures the streusel bakes evenly without sinking into the cake.
Layer and Bake for Even Rising
Preheat your oven to 350°F and grease a 9x13-inch baking pan or line it with parchment paper. Pour half of the cake batter into the prepared pan and spread it evenly. Sprinkle half of the streusel mixture over the batter, pressing down lightly with your fingers to ensure good contact. This layering technique creates the signature coffee cake texture.
Add the remaining cake batter, spreading it evenly over the streusel. Top with the remaining streusel, again pressing down gently to create a cohesive layer. Bake for 45-50 minutes, or until a toothpick inserted into the center comes out clean and the top is golden brown. The edges should pull away slightly from the pan, indicating proper doneness.
Cool and Serve for Maximum Moisture Retention
Remove the coffee cake from the oven and let it cool in the pan for 10 minutes. This brief resting period allows the cake to set slightly, preventing it from falling apart when transferred. Use a sharp knife to loosen the edges, then invert the cake onto a wire rack to cool completely. The streusel will firm up as it cools, creating that perfect contrast with the tender cake layers.
Slice the coffee cake into 8 equal servings and serve warm or at room temperature. The cake should have a moist, tender crumb with a crisp, cinnamon-scented streusel on top. Store any leftovers in an airtight container at room temperature for up to 3 days, or refrigerate for up to 5 days. The moist texture will be preserved best when served within the first two days of baking.
Pro Tips For Making America'S Test Kitchen Coffee Cake
- USE COLD BUTTER: I learned this the hard way—when the butter’s too soft, the cake turns dense instead of tender. Take the butter straight from the fridge (or even the freezer for 10 minutes) and cut it into cubes before creaming. The recipe calls for room temp, but "room temp" is subjective; cold butter emulsifies better and keeps layers light.
- SIFT THE FLOUR: Yes, even if it looks fine. The ATK recipe relies on a light, airy crumb, and sifting the flour removes lumps and incorporates air. Use a fine-mesh sieve and tap it gently against the bowl—don’t just pour. (I skip this when I’m lazy, but the texture is noticeably better when I don’t.)
- DON’T OVERMIX THE BATTER: Stop as soon as the flour disappears. The second you see streaks of dry flour, call it done. Overmixing develops gluten, which makes the cake tough. The recipe’s yield is tight—every extra fold tightens the crumb. Use a spatula to gently fold just until combined.
- PARE THE BUTTER GREASE: This isn’t the prettiest method, but it’s the tastiest. After greasing the pan with butter, use a paring knife to scrape off any excess—especially the edges. A thin, even layer prevents sticking, and it keeps the cake from absorbing too much butter. (Your future self will thank you when you slice clean, golden layers.)
Perfect pairings for these flavors
Morning Coffee Elevation
Pair this coffee cake with a freshly brewed cold brew concentrate—the deep, smooth notes complement the cake’s vanilla and cinnamon without overpowering. I like Stumptown Cold Brew for its balanced acidity. For a lighter option, Starbucks Pike Place Roast enhances the cake’s caramelized streusel. Always serve coffee at room temperature to avoid cooling the cake too quickly. ☕
Creamy Toppings
A dollop of whipped cream sweetened with vanilla sugar adds luxurious texture. For a tangy twist, try mascarpone cheese mixed with honey—just 1 tbsp per slice—to cut through the richness. My go-to is Land O’Lakes heavy cream, whipped to soft peaks with 1 tsp powdered sugar. Serve immediately after slicing to prevent sogginess. 🥛
Seasonal Fruit Pairings
In summer, top slices with sliced peaches (lightly macerated in lemon juice) and a sprinkle of flaky sea salt. For fall, roasted apples with cinnamon sugar create a cozy contrast. I use Honeycrisp apples—their natural sweetness balances the cake’s streusel. In winter, fresh berries (raspberries or blackberries) add a bright, tart pop. 🍎
Spiced Liqueur Drizzle
For an adult twist, drizzle warm slices with Kahlúa coffee liqueur mixed with heavy cream (1:1 ratio). A ½ tsp cinnamon per 2 tbsp mixture enhances the cake’s flavors. For a non-alcoholic version, substitute with vanilla syrup and a pinch of cayenne for subtle heat. Serve immediately after drizzling to prevent absorption. 🌶️
Tea Time Harmony
Earl Grey tea’s bergamot notes elevate the cake’s vanilla, while chamomile adds a soothing contrast. Brew loose-leaf tea (I prefer Harney & Sons) at 200°F for delicate flavors. For a dessert-focused pairing, jasmine green tea with honey complements the streusel’s caramelized sweetness. Serve tea in pre-warmed cups to maintain temperature harmony. 🍵

Frequently asked questions
Why does this coffee cake stay moist longer than others?
The secret lies in the brown sugar and milk combo, which retains moisture better than granulated sugar and water. The streusel is folded into the batter (not just sprinkled on top), creating even distribution of butter and sugar that locks in freshness for days. Plus, the streusel's oats absorb excess moisture, preventing dryness.
Can I substitute quick oats for old-fashioned in the streusel?
No—quick oats will make the streusel gummy rather than crisp. Old-fashioned oats toast better and hold their shape during baking. If you're out of old-fashioned, toast regular oats in a dry pan for 3-4 minutes until golden, then pulse in a food processor to mimic the texture.
What's the best way to reheat stale coffee cake?
Wrap individual slices in foil and warm at 350°F for 5-7 minutes until the streusel is crisp again. For extra moisture, brush with simple syrup (equal parts sugar and water) before reheating. Microwaving steals crispness—always use the oven method.
Can I make this in a bundt pan instead of a 9x13-inch pan?
Yes, but expect a different shape and potentially uneven baking. The cake batter should be divided evenly between two 10-cup bundt pans. Reduce baking time to 35-40 minutes and check for doneness 5 minutes early. The streusel layers will be more concentrated at the top.
Why does my streusel turn out too crumbly or too sticky?
Too crumbly? The butter was too cold—cut it into smaller pieces next time. Too sticky? Chill the streusel for 10-15 minutes before using. For perfect texture, the streusel should hold when pressed but still crumble easily. If it sticks to your fingers, add 1 tbsp more oats.
