Blueberry yogurt loaf cake is a dense, moist quick bread made with Greek yogurt, fresh blueberries, and a simple lemon glaze, baked in a standard loaf pan at 350 F / 175 C for about 55 minutes.
I started making this on Sunday mornings when I had a tub of yogurt going soft in the fridge and a carton of blueberries that needed using. It became the thing I bake when I want something that isn’t too sweet but still feels like dessert.
The yogurt does two jobs here. It keeps the crumb tender for days, and it adds a slight tang that balances the sugar. Toss the blueberries in a spoonful of flour before folding them in, or they’ll sink straight to the bottom.
Slice it thick, still a little warm, and the glaze will pool into the crumb instead of just sitting on top.
Why You’ll Love This Recipe
- Stays moist for days thanks to the yogurt in the batter
- One bowl for the batter, no mixer required
- Fresh blueberries stay suspended instead of sinking to the bottom
- Freezer-friendly, so you can bake ahead for busy mornings
Ingredient Notes
- Greek yogurt: Use full-fat for the richest crumb. Low-fat or a plant-based yogurt works too, but the loaf turns out slightly drier.
- Blueberries: Fresh or frozen both work. Use frozen berries unthawed and toss them in flour first so they don’t sink.
- Neutral oil: Vegetable or sunflower oil keeps the crumb soft longer than butter would. Avoid strong-flavored oils like olive oil here.
- Lemon zest: Adds brightness that cuts through the yogurt’s tang. Orange zest is a fine swap if that’s what you have.
- All-purpose flour: Weigh it if you can. Scooping straight from the bag packs in extra flour and makes the loaf dense.
Moist Blueberry Yogurt Loaf Cake with a Lemon Glaze
Ingredients
Method
- Heat the oven to 175 C / 350 F. Grease a 9x5-inch loaf pan and line it with parchment paper.
- Whisk the flour, baking powder, baking soda, and salt together in a bowl.
- In a separate bowl, whisk the sugar and eggs together for 1 to 2 minutes until pale.
- Add the yogurt, oil, vanilla, and lemon zest to the egg mixture and whisk until smooth.
- Fold the dry ingredients into the wet mixture just until no dry streaks remain.
- Toss the blueberries in 1 tablespoon of flour, then fold them gently into the batter.
- Pour the batter into the prepared pan and smooth the top with a spatula.
- Bake for 55 to 60 minutes, until a toothpick inserted in the center comes out clean and the top is golden.
- Cool the loaf in the pan for 10 minutes, then transfer it to a wire rack to cool completely.
- Whisk the powdered sugar and lemon juice into a smooth glaze and drizzle it over the cooled loaf before slicing.
Notes
- Toss berries in flour right before folding in, not earlier, or the coating gets soggy.
- Don't overmix once the flour goes in, stop as soon as the streaks disappear.
- Glaze only once the loaf is fully cool, warm cake melts the icing right off.
- A toothpick from the center is the real test, not just the edges of the loaf.
Tips for Success
- Toss blueberries in a tablespoon of flour before folding them in so they don’t sink to the bottom.
- Use full-fat Greek yogurt for the richest crumb; low-fat works but the loaf turns out slightly drier.
- Check the cake at 50 minutes and tent it with foil if the top is browning too fast.
- Let the loaf cool completely before glazing, or the icing will melt and slide off instead of setting.
- Weigh your flour instead of scooping with a cup to avoid a dense, gummy loaf.
Variations
- Swap blueberries for raspberries or diced strawberries, keeping the same flour-toss trick to prevent sinking.
- Add half a teaspoon of ground cardamom to the batter for a warmer, slightly floral background note.
- Make it dairy-free by using coconut yogurt and a neutral oil instead of Greek yogurt.
Storage and Reheating
Store the loaf covered at room temperature for up to 2 days, or in the fridge for up to 5 days once it’s glazed.
Wrap unglazed slices tightly in plastic and freeze for up to 3 months. Thaw at room temperature for about an hour before glazing and serving.
A few seconds in the microwave, about 10 to 15 seconds, brings back that just-baked softness if you’re eating it cold from the fridge.
Serving Suggestions
Serve slices with a smear of salted butter while the loaf is still faintly warm.
It pairs well with a cup of black tea or a lemony iced coffee on a warm afternoon.
For dessert, add a small scoop of vanilla ice cream and a few extra blueberries on the side.
FAQ
Why did my blueberry yogurt loaf cake sink in the middle?
A sunken middle usually means the loaf came out before it finished baking, or the oven door got opened too early. Check doneness with a toothpick in the very center, it should come out clean, not just from the edges. Underbaked batter with wet blueberries can also collapse as it cools, so bake the full 55 to 60 minutes.
Can I use frozen blueberries instead of fresh in this loaf cake?
Yes, frozen blueberries work fine, just don’t thaw them first. Toss them straight from the freezer in a spoonful of flour before folding into the batter, since thawed berries release extra liquid and bleed color into the crumb. The bake might run 5 minutes longer, so start checking at 55 minutes.
Can I freeze blueberry yogurt loaf cake before glazing it?
Yes, freezing the loaf unglazed gives the cleanest results. Wrap it tightly in plastic wrap and foil, then freeze for up to 3 months. Thaw at room temperature for about an hour, then make the lemon glaze fresh and drizzle it right before serving.
What goes well with blueberry yogurt loaf cake?
Salted butter, a cup of black tea, or a scoop of vanilla ice cream all work well alongside this loaf. It’s rich enough to stand alone for breakfast with coffee, but sweet enough to serve as a simple dessert with fresh berries on the side.
Is blueberry yogurt loaf cake gluten free?
Not as written, since this recipe uses regular all-purpose flour. Swap in a 1:1 gluten-free baking blend to make it gluten free, the yogurt and oil keep the crumb moist enough that most blends work without much adjustment. Double check your baking powder too, since some brands aren’t certified gluten free.
What’s the difference between this loaf and a classic pound cake?
Blueberry yogurt loaf cake uses yogurt and oil instead of the butter-heavy ratio in a classic pound cake, which gives it a lighter, more tender crumb and a slight tang. Pound cake leans denser and richer, while this loaf stays moist for days thanks to the yogurt.
