Full Ingredients

For the Vanilla Pound Cake Base

• 1 1/2 cups (190 g) all-purpose flour, spooned and leveled
• 1/2 tsp baking powder
• 1/2 tsp fine sea salt
• 3/4 cup (170 g) unsalted butter, very soft, plus extra for greasing the pan
• 1 cup (200 g) granulated sugar
• 3 large eggs, at room temperature
• 2 tsp pure vanilla extract
• 1/4 cup (60 g) full-fat sour cream or plain Greek yogurt, at room temperature
• 1/4 cup (60 ml) whole milk, at room temperature

For the Matcha Swirl

• 1–1 1/2 tbsp (6–9 g) culinary-grade matcha green tea powder, sifted if clumpy
• 1 tbsp (15 ml) whole milk, at room temperature (to loosen the matcha batter, as needed)

For the Pan & Finishing

• Butter or nonstick baking spray, for greasing the pan
• Parchment paper, for a sling (recommended)
• Powdered sugar, for light dusting on top (optional)

Step-by-Step Instructions

Step 1: Prepare your pan and preheat the oven

Set an oven rack in the center of your oven and preheat to 325°F (165°C). Lightly grease a 9 x 5-inch loaf pan with butter or nonstick spray. Cut a strip of parchment paper wide enough to cover the bottom and extend up the two long sides of the pan, leaving overhang as “handles.” Press the parchment into the pan and lightly grease the parchment as well. This makes it much easier to lift out the delicate pound cake without breaking it.

Step 2: Mix the dry ingredients

In a medium bowl, whisk together the flour, baking powder, and salt until well combined and lump-free. Set this bowl aside. Having the dry ingredients pre-mixed helps them incorporate evenly into the batter later and prevents overmixing, which can make the cake dense or tough.

Step 3: Cream the butter and sugar

In a large mixing bowl, add the very soft butter and granulated sugar. Using a hand mixer or stand mixer fitted with the paddle attachment, beat on medium-high speed for 3–4 minutes, until the mixture is very pale, fluffy, and increased in volume. Scrape down the sides and bottom of the bowl halfway through. Properly creaming the butter and sugar is key to a fine, tender crumb; you are whipping tiny air bubbles into the fat that will expand in the oven.

Step 4: Add the eggs and vanilla

Beat in the eggs one at a time, mixing on medium speed after each addition just until incorporated before adding the next. Scrape the bowl as needed. Once all the eggs are in, add the vanilla extract and mix briefly to combine. The batter may look slightly curdled at this point; that is normal and will smooth out once the dry ingredients are added.

Step 5: Finish the batter and divide it

Add the sour cream (or Greek yogurt) to the bowl and mix on low speed until just blended. Now add the dry ingredients in two additions, alternating with the 1/4 cup (60 ml) milk: add half the flour mixture and mix on low just until almost combined, then add all the milk and mix briefly, then add the remaining flour mixture and mix until no dry streaks remain. Do not overbeat. The batter should be thick, smooth, and velvety. Weigh or eyeball the batter and divide it evenly between two medium bowls.

Step 6: Make the matcha batter and swirl

To one bowl of batter, add the matcha powder. If your matcha is clumpy, sift it in through a small sieve. Add the extra 1 tbsp (15 ml) milk and stir gently with a spatula until the batter is an even, vibrant green. You should now have one bowl of vanilla batter and one bowl of matcha batter of similar consistency.

To create the swirl, spoon large dollops of batters into the prepared loaf pan in alternating colors: a scoop of vanilla, then a scoop of matcha beside or on top, and so on, building up in 2–3 layers. When all the batter is in the pan, use a thin knife or skewer to gently swirl through the batter 3–4 times, making loose “S” or figure-eight shapes. Do not over-swirl, or you will lose the distinct marbling.

Step 7: Bake, cool, and serve

Place the pan in the preheated oven and bake for about 50–60 minutes, or until the top is domed and lightly golden, and a toothpick or thin skewer inserted into the center comes out clean or with a few moist crumbs, but no wet batter. If the top is browning too quickly before the center is done, tent loosely with foil for the last 10–15 minutes.

Remove the cake from the oven and set the pan on a wire rack. Cool in the pan for 15 minutes, then use the parchment overhang to carefully lift the loaf out onto the rack. Peel away the parchment and let the cake cool until just slightly warm or at room temperature, about 30–45 minutes more. Dust the top lightly with powdered sugar if desired, slice with a sharp serrated knife, and enjoy the beautiful matcha-vanilla swirls.

Pro Tips

• Use room-temperature ingredients. Soft butter, and eggs plus dairy that are not cold, blend together much more smoothly and give the pound cake a finer crumb.
• Choose good matcha. A fresh, vibrant green culinary-grade matcha will give better color and a cleaner, less bitter flavor than old or dull matcha powder.
• Do not overmix once the flour goes in. Mix only until you no longer see dry spots. Overmixing develops gluten and can make the loaf tough.
• Swirl gently. A few slow, deliberate passes with a knife are enough. Too much swirling blends the batters and turns the cake a uniform, muddy color.
• Let it cool before slicing. Cutting while hot can crush the tender crumb and smear the swirl pattern, so give it time to set.

Variations

• Citrus-matcha loaf: Add 1 tbsp finely grated lemon or orange zest to the vanilla batter along with the vanilla extract. The bright citrus notes pair beautifully with the grassy matcha.
• Almond twist: Replace 1 tsp of the vanilla with 1 tsp almond extract, and sprinkle 2–3 tbsp sliced almonds over the top of the batter before baking.
• Mini loaves or tea cakes: Bake the batter in mini loaf pans or a muffin tin for individual matcha swirl cakes. Reduce baking time to about 18–25 minutes, depending on size, and test early.

Storage & Make-Ahead

Once completely cool, wrap the matcha swirl pound cake tightly in plastic wrap or store in an airtight container at room temperature for up to 3 days. For slightly longer storage (up to 5 days), keep it in the refrigerator, well wrapped, and let slices come to room temperature before serving for the best texture.

To freeze, slice the loaf and wrap each slice individually in plastic, then place them together in a freezer bag. Freeze for up to 2 months. Thaw slices at room temperature for 30–45 minutes, or warm gently in a low oven (300°F / 150°C) for 5–8 minutes. This cake also works well as a make-ahead dessert; you can bake it the day before serving and keep it covered at room temperature overnight.
