This healthy pound cake is a tender, lightly sweet loaf made with whole-wheat pastry flour, a little all-purpose flour, Greek yogurt, and less butter than a traditional pound cake. It is easy to slice for breakfast or dessert, and the yogurt helps keep the crumb moist without making the cake heavy.
Ingredients
- 1 1/2 cups (180 g) whole-wheat pastry flour
- 1/2 cup (60 g) all-purpose flour
- 1 teaspoon (4 g) baking powder
- 1/4 teaspoon (1.5 g) fine salt
- 6 tablespoons (85 g) unsalted butter, softened
- 2/3 cup (135 g) granulated sugar
- 2 tablespoons (30 ml) neutral oil, such as canola or sunflower
- 3 large eggs (about 150 g without shells), at room temperature
- 1/2 cup (120 g) plain Greek yogurt, preferably 2% or whole milk, at room temperature
- 2 teaspoons (10 ml) vanilla extract
- 1 teaspoon finely grated lemon zest (about 2 g), optional
Instructions
- Bring the cold ingredients toward room temperature. Set out the butter, eggs, and yogurt about 30 minutes before mixing. The butter should give slightly when pressed but should not be greasy or melted. Room-temperature ingredients blend into a smoother batter, which helps the loaf bake evenly.
- Prepare the pan and oven. Set a rack in the middle of the oven and heat it to 350°F (175°C). Grease a 9-by-5-inch (23-by-13-cm) loaf pan, then line it with a strip of parchment paper that overhangs the long sides. The paper makes it easier to lift out the cake after cooling.
- Combine the dry ingredients. In a medium bowl, whisk together the whole-wheat pastry flour, all-purpose flour, baking powder, and salt. Break up any small lumps so the baking powder is distributed throughout the flour. Set the bowl aside.
- Cream the butter and sugar. In a large bowl, beat the softened butter and sugar with a hand mixer on medium speed for about 2 minutes, until lighter in color and fluffy. Scrape down the bowl, then beat in the oil. A stand mixer with the paddle attachment also works; avoid whipping for a long time, since excess air can make the cake rise quickly and then sink.
- Add the eggs and flavorings. Beat in the eggs one at a time, mixing until each is mostly incorporated before adding the next. Scrape the bowl again, then mix in the Greek yogurt, vanilla, and lemon zest if using. The mixture may look slightly curdled at this point; that is generally fine and should smooth out when the flour is added.
- Finish the batter. Add the dry ingredients in two additions, mixing on low speed just until no dry streaks remain. Finish with a few folds by hand, scraping the bottom and sides of the bowl. The batter will be thick. Do not keep beating once the flour is incorporated, or the loaf can turn out tougher.
- Fill the pan and bake. Scrape the batter into the prepared pan and smooth the top. Bake for 55 to 65 minutes, rotating the pan once after about 35 minutes if your oven browns unevenly. The top should be golden, the center should spring back lightly, and a wooden pick inserted in the middle should come out clean or with a few moist crumbs. For egg safety, check that the center reaches at least 160°F (71°C), the USDA FSIS safe minimum temperature for egg dishes, with an instant-read thermometer. If the top browns before the center is done, loosely tent it with foil for the remaining baking time.
- Cool before slicing. Set the pan on a cooling rack for 15 minutes. Run a thin knife along the unlined ends, use the parchment to lift out the loaf, and let it cool on the rack for another 60 minutes before cutting. A warm loaf is more delicate and can compress or crumble when sliced.
Tips
- Measure flour gently. Spoon flour into the measuring cup and level it off, or use the gram weights. Scooping straight from the bag can pack in extra flour and make a yogurt-based loaf dry. Whole-wheat pastry flour is milder and finer than regular whole-wheat flour; if you substitute regular whole-wheat flour, expect a slightly denser, more assertive crumb.
- Use softened, not melted, butter. Butter that is too cold will not cream properly, while melted butter can produce a heavier texture. If you forgot to set it out, cut it into small cubes and leave it at room temperature for about 15 minutes, checking that it is pliable but still cool.
- Keep mixing brief after adding flour. A few streaks can be folded in by hand. Overmixing develops gluten and is a common reason loaf cakes turn chewy rather than tender. Scrape the bowl well so no pockets of flour remain at the bottom.
- Check your pan and oven. This batter is sized for a 9-by-5-inch loaf pan. A smaller pan may overflow; a wider pan can make a shorter loaf that finishes earlier. Oven temperatures vary, so start checking at 55 minutes and use the center tests rather than relying on color alone.
Serving Suggestions
Let the cake cool completely for neat slices, then serve it plain or with a light dusting of powdered sugar. It is also good with fresh berries, sliced peaches, or a spoonful of lightly sweetened yogurt. For a simple dessert plate, add fruit and a small drizzle of honey or maple syrup; the loaf itself is deliberately not very sweet, so these toppings can be adjusted to taste.
For brunch or an afternoon snack, cut slices about 1/2 inch (1.3 cm) thick and serve with tea or coffee. If you want a slightly warm slice, toast it briefly in a dry skillet over low heat, watching closely so the cut surface does not scorch. The cake is sturdy enough to pack for a picnic once it has cooled and been wrapped securely.
Variations
Orange or lemon loaf: Replace the lemon zest with 1 teaspoon (about 2 g) finely grated orange zest, or use 2 teaspoons (about 4 g) lemon zest for a brighter citrus flavor. A teaspoon of citrus juice can be added too, but avoid adding much more liquid because the batter is balanced for the stated yogurt amount.
Berry version: Fold in 3/4 cup (about 100 g) fresh blueberries or raspberries after the flour is mixed in. Pat washed berries dry first, and fold gently so they do not break up and streak the batter. Frozen berries can be used straight from the freezer; the loaf may need a few extra minutes in the oven.
Nut or spice version: Fold in 1/3 cup (40 g) chopped walnuts or pecans, or add 1/2 teaspoon (1 g) ground cinnamon. For a more tender, mild-flavored cake, you can replace the whole-wheat pastry flour with the same weight of all-purpose flour. That swap makes the loaf less whole-grain in character but keeps the method unchanged.
Dairy-free adjustment: Use a plant-based butter stick and an unsweetened, thick dairy-free yogurt in equal amounts. Choose a product with a texture similar to Greek yogurt rather than a thin drinking-style yogurt; a thinner substitute can loosen the batter and change the baking time. Results vary by brand, so check the center carefully.
Storage and Reheating
Cool the cake fully, then store it in an airtight container. Because this loaf contains yogurt and eggs, refrigerate it within 2 hours of baking or serving. It keeps well in the refrigerator for 3 to 4 days. Chilling firms the crumb, so let a slice stand at room temperature for 15 to 20 minutes before serving if you prefer a softer texture.
To freeze the loaf, wrap it tightly in plastic wrap and then foil, or place individually wrapped slices in a freezer-safe container. Freeze for up to 2 months for best texture. Thaw wrapped slices in the refrigerator overnight or at room temperature for about 1 to 2 hours. Wrapping the cake before freezing helps limit drying and makes it easy to take out only the number of slices you need.
Reheating is optional. If you warm a refrigerated slice in the microwave, USDA guidance is to reheat leftovers to 165°F (74°C); use a food thermometer to check the center, and remember that heating the cake that much can make it drier. For a gentler serving temperature, allow the slice to come to room temperature instead.
Frequently Asked Questions
Is this pound cake actually healthy?
“Healthy” can mean different things, so this recipe is best described by what it contains: whole-wheat pastry flour, Greek yogurt, a moderate amount of sugar, and less butter than a classic pound cake. It is still a sweet baked dessert, and its texture and flavor are designed to be satisfying rather than to imitate a traditional cake exactly.
Can I use regular whole-wheat flour instead of pastry flour?
Yes. Use the same amount by weight, 180 g, but expect a denser crumb and a more pronounced whole-wheat flavor. Whole-wheat pastry flour is more finely milled and generally produces a softer result. If you do not have it, an equal weight of all-purpose flour is another workable swap, with a lighter, less grain-forward cake.
Can I use nonfat Greek yogurt?
Yes, plain nonfat Greek yogurt can replace the 2% or whole-milk yogurt in the same quantity. The cake may be a little less rich, but it should still bake successfully. Avoid flavored or sweetened yogurt because it changes both the sweetness and flavor, and check the label for a thick Greek-style texture.
Why did my loaf sink in the middle?
A sunken center usually means the cake was underbaked, the oven door was opened early, or the batter was overmixed or given too much leavening. Make sure the baking powder is measured level, avoid opening the oven during the first 45 minutes, and use a tester plus a thermometer to check the center before removing the pan.
Can I bake this in a round cake pan or muffin tin?
A different pan can work, but the baking time will change. A standard 9-inch (23-cm) round pan will make a shallower cake, so begin checking earlier, around 35 to 40 minutes. Muffins bake faster still; fill the cups about two-thirds full and start checking around 18 minutes. In either case, rely on doneness checks rather than transferring the loaf’s bake time directly.
