Ingredients for america's test kitchen coffee cake

The secret to this legendary coffee cake lies in these carefully balanced ingredients—each playing its part for that perfect buttery crumb and spiced streusel.

The butter here is non-negotiable—European-style or Land O'Lakes both work, but stay away from margarine. The coffee? Cold brew concentrate from Stumptown or La Colombe adds depth, but instant works in a pinch. For the streusel, toast your walnuts in a dry pan until fragrant—3-4 minutes—they should smell like heaven. The cinnamon? Penzeys or the bulk section at Whole Foods for the freshest grind. And that powdered sugar? Confectioners' sugar from Dominique sifts perfectly—no clumps, every time.

No coffee? Espresso powder at half the amount works wonders, or even strong black tea if that's what you've got. Swapping butter for coconut oil? Use full-fat and chill it first—it behaves more like butter. Running short on walnuts? Pecans or hazelnuts toast just as beautifully. The brown sugar? Light or dark both work, but light gives a slightly sweeter crumb. And if you're feeling fancy, add 1 tsp bourbon to the coffee for a grown-up twist—trust me, it's worth it.

This cake keeps beautifully—3 days wrapped at room temp or 1 week in the fridge. For reheating, 30 seconds at 350°F brings back that fresh-from-the-oven warmth. The streusel topping? Freeze it separately if you're making it ahead—just sprinkle on top when you bake. And if you're prepping for a crowd, double the streusel. You can't have too much of that caramelized goodness.

Step-by-step instructions for america's test kitchen coffee cake

Here's how to bake layers of tender coffee cake with buttery streusel and aromatic spice bursts!

Preheat your oven to 350°F and grease a 9x13-inch baking pan generously with butter. I always use a light coating of butter plus a sprinkle of flour to prevent sticking—this cake needs to release cleanly from the pan.

In a large mixing bowl, whisk together the 3 cups all-purpose flour, 2 teaspoons baking powder, ½ teaspoon baking soda, and ½ teaspoon salt. Sift the dry ingredients directly into the bowl to avoid clumping—this ensures your cake will be light and airy. In a separate bowl, beat the 1 cup unsalted butter and 1 cup granulated sugar until light and fluffy, about 3-4 minutes.

Add the 2 whole eggs one at a time, mixing well after each addition. Stir in the ½ cup brewed coffee (cooled completely) and 1 tablespoon vanilla extract. Here's the thing—adding the coffee to the wet ingredients creates a tender crumb that stays moist longer, even if you slice it the next day. Gradually mix in the dry ingredients until just combined, being careful not to overmix.

In a medium bowl, combine the ½ cup brown sugar, ½ cup all-purpose flour (reserved from the cake batter), 1 tablespoon ground cinnamon, and ½ teaspoon allspice. Cut in the ½ cup cold unsalted butter using a pastry cutter or your fingers until the mixture resembles coarse crumbs with pea-sized butter pieces—this texture is key for that perfect streusel texture.

Fold in the ½ cup toasted chopped walnuts (toast them in a dry skillet over medium heat for 3-4 minutes until fragrant). The walnuts add wonderful crunch and depth of flavor. Keep this mixture cold until ready to use—if it gets too warm, the butter will melt and the streusel will clump.

Spread half of the cake batter evenly into the prepared pan. Sprinkle half of the streusel mixture over the batter, then add the remaining batter. Top with the remaining streusel, pressing down gently but not compacting it too much—you want those streusel pockets to stay intact and crispy. Here's where it gets fun: use a knife to make 4-6 swirling lines through the streusel to the bottom of the pan. This creates those beautiful streaks you see in classic coffee cakes.

Bake for 40-45 minutes until a toothpick inserted in the center comes out clean and the top is golden brown. The cake is ready when it springs back slightly when pressed in the center—don't overbake, or it'll dry out. The edges should be puffed and the streusel should be golden and slightly crisp.

Let the coffee cake cool in the pan for 10 minutes before transferring it to a wire rack to cool completely. Here's my pro tip: dust the warm cake with ¼ cup powdered sugar right after it comes out of the oven. The heat will help the powdered sugar melt slightly, creating a beautiful, snowy finish that looks stunning when you serve it.

Slice into 8 equal portions and serve warm with a cup of freshly brewed coffee. The cake should have a tender, moist crumb with pockets of buttery streusel and those beautiful cinnamon-spiced streaks throughout. Each bite delivers a perfect balance of sweet cake, spiced streusel, and rich coffee flavor—this is what makes this recipe truly special!

Make-ahead tips for this america's test kitchen coffee cake

Prep Ahead for Perfection

The beauty of this coffee cake is how well it handles advance prep. I like to make the streusel topping 2 days ahead—just store it in an airtight container in the fridge. The batter, however, should be mixed no more than 12 hours ahead to maintain its light texture.

Keep it covered in the fridge, and let it sit at room temp for 30 minutes before assembling. This simple step prevents a dense crumb. 💫

Freezer-Friendly Layers

For a true make-ahead masterpiece, assemble the entire cake (batter + streusel) in your pan and freeze it unbaked for up to 2 months. When ready to bake, remove from the freezer and let it thaw in the fridge overnight.

Bake as directed—just add 5-10 minutes to the cooking time since the pan will be colder. The streusel will still crisp beautifully, and the coffee notes will be just as vibrant.

Streusel Makeover

Want to take your streusel to the next level? Toast the walnuts with ½ tsp cinnamon while you're toasting them—this infuses their flavor even deeper. For extra richness, swap 2 tbsp of the butter for 2 tbsp brown sugar in the streusel.

I also love adding ¼ tsp cardamom for a sophisticated twist that pairs beautifully with the coffee undertones. Store any extra streusel in the freezer for up to 3 months—perfect for last-minute cake emergencies!

Coffee Cake Timeline

Here's my foolproof schedule: Mix the batter Day 1 evening, refrigerate overnight. Make the streusel Day 2 morning, toast the walnuts while the oven preheats. Assemble and bake immediately for fresh-from-the-oven perfection.

If you're prepping for a brunch, assemble the cake the night before, cover tightly, and bake straight from the fridge—just add 5 minutes to the baking time. The aroma alone will wake everyone up! ⏰

Serving Strategies

This cake tastes best when served warm but stays moist for 3 days at room temperature if wrapped tightly in plastic. For reheating, wrap a slice in foil and warm at 350°F for 5-7 minutes—the foil prevents drying.

Pro tip: Brush warm slices with 1 tsp coffee syrup (equal parts sugar and water, simmered with a splash of coffee) right before serving. It adds that restaurant-quality finish without extra effort. 🥖

Batch Baking Secrets

Making two cakes? Double the streusel and divide it between two pans. For a crowd, bake one cake, let it cool completely, then slice and freeze individual portions on a tray before transferring to a bag. They'll reheat beautifully—just 10 seconds in the microwave (covered) brings back that fresh-baked magic.

I've even made mini coffee cakes using 8-inch pans—just reduce all ingredients by half and bake for 25-30 minutes. Perfect for individual servings! 💡
