This loaf cake has become a staple in my house for so many reasons. It’s one of those recipes that just works, every single time. Here’s why I think you’ll love it too:

It’s easy to make. You don’t need any fancy equipment or complicated steps. Just a bowl, a whisk, and a little patience.

Honestly, this recipe won me over the first time I baked it. It’s become our go-to treat, and I bet it’ll become yours too.

Ingredients for Lemon Blueberry Loaf Cake Recipe

Alright, here’s what you’ll need to make this beauty. I like to get everything measured out before I start – it makes the whole process so much smoother. All ingredients should be at room temperature for the best texture.

1 1/2 cups all-purpose flour
1 teaspoon baking powder
1/2 teaspoon salt
1/2 cup unsalted butter, softened
1 cup granulated sugar
2 large eggs
1 teaspoon vanilla extract
1 tablespoon lemon zest
1/2 cup milk
1 1/2 cups fresh blueberries
For the glaze: 1 cup powdered sugar, 2 tablespoons lemon juice

Ingredient Notes for Lemon Blueberry Loaf Cake Recipe

Fresh blueberries are really the star here – they give the best texture and burst of flavor. If you’re using frozen berries, don’t thaw them first, and definitely toss them in a little flour to keep them from sinking. Your butter needs to be soft, not melted – you want it to hold its shape but give easily when you press it. That lemon zest is where the magic lives, so make sure you only grate the yellow part; the white pith is bitter and will ruin the vibe. I usually use whole milk because it makes the cake extra tender, but 2% works just fine. If you need this dairy-free, go ahead and swap the butter for a good vegan stick and use almond or oat milk – it’ll still be delicious.

Equipment Needed

You don’t need anything fancy for this one. Here’s what I grab from my kitchen:

A 9×5 inch loaf pan
Mixing bowls (one for dry, one for wet)
An electric mixer or a good whisk and some elbow grease
A spatula for folding in the blueberries
A wire rack for cooling
A toothpick for testing doneness

I also like to line my pan with parchment paper – it makes lifting the cake out so much easier. Trust me, it’s worth the extra minute.

How to Make Lemon Blueberry Loaf Cake Recipe

Okay, here’s where the magic happens! This lemon blueberry loaf cake recipe comes together pretty quickly, and the smell while it bakes is absolutely incredible. Just follow these steps and you’ll be golden. Remember to preheat your oven to 350°F (175°C) and grease your 9×5 inch loaf pan before you start mixing.

Step-by-Step Instructions for Lemon Blueberry Loaf Cake Recipe

Prep your pan. Grease your loaf pan well with butter or cooking spray. I like to line it with parchment paper too – it just makes lifting the cake out so much easier.
Mix the dry stuff. In a medium bowl, whisk together the flour, baking powder, and salt. Set that aside for now.
Cream the butter and sugar. In a large bowl, beat the softened butter and sugar together until it’s light and fluffy. This usually takes about 2-3 minutes with an electric mixer. You want it to look pale and airy.
Add the eggs and flavorings. Beat in the eggs one at a time, making sure each one is fully incorporated before adding the next. Then mix in the vanilla extract and that lovely lemon zest.
Alternate wet and dry. Now, with the mixer on low, add about a third of the flour mixture, then half the milk. Keep alternating, starting and ending with the flour. Mix just until everything is combined – don’t go crazy here.
Fold in the blueberries. Here’s the trick – toss your blueberries in a little flour first (this stops them from sinking to the bottom). Then gently fold them into the batter with a spatula. Be gentle, you don’t want to burst them.
Bake it. Pour the batter into your prepared pan and smooth the top. Bake for 55-60 minutes, or until a toothpick inserted in the center comes out clean. If the top starts getting too dark, you can tent it with foil.
Cool it properly. Let the cake cool in the pan for about 10 minutes, then carefully transfer it to a wire rack to cool completely. And I mean completely – don’t even think about adding the glaze until it’s cool, or it’ll just melt right off.

Tips for a Perfect Lemon Blueberry Loaf Cake

I’ve baked this lemon blueberry loaf cake recipe more times than I can count, so let me share a few things I’ve learned. First, definitely toss those blueberries in flour before folding them in – nobody wants all the berries at the bottom of the cake. Second, don’t overmix once you add the flour. A few streaks are fine; overmixing makes the cake tough. Third, make sure your ingredients are at room temperature – it makes a huge difference in how well everything creams together. And when you’re testing for doneness, stick that toothpick right in the center. One more thing – I always zest the lemon before juicing it. That way you don’t end up with a squishy lemon that’s impossible to grate. Trust me, it’s a game-changer.

Variations for Lemon Blueberry Loaf Cake Recipe

This lemon blueberry loaf cake recipe is fantastic as-is, but it’s also super fun to play around with! When I’m out of blueberries, I swap in raspberries or blackberries – they work beautifully and give a slightly different tartness. For a crunchier top, add a simple streusel made of butter, flour, and brown sugar before baking. You can also switch up the citrus and use lime zest instead of lemon for a zesty twist. Need it gluten-free? Just use a 1:1 gluten-free flour blend. And if you’re feeling extra fancy, swirl in some softened cream cheese before baking – decadent and delicious! Try one of these next time.

Serving Suggestions

I love serving this cake with a light dusting of powdered sugar on top – it looks so pretty and adds just a touch of extra sweetness. For a real treat, a dollop of whipped cream or a handful of fresh berries on the side takes it over the top. It’s perfect with your morning coffee or tea, but honestly, it’s just as good as a light dessert after dinner. I’ve even thrown a few slices in a basket for picnics, and they always get devoured. You really can’t go wrong with this one!

Storing and Reheating Lemon Blueberry Loaf Cake

I always make sure to save some of this lemon blueberry loaf cake recipe for later – it keeps so well! Just pop it in an airtight container and it’ll stay fresh at room temperature for up to 3 days. If you want to keep it longer, wrap it tightly in plastic wrap and foil, then freeze for up to 3 months. When you’re ready to enjoy a slice, warm it in the microwave for 10-15 seconds, or pop it in a 300°F oven for about 5 minutes. It tastes almost as good as fresh!

Frequently Asked Questions about Lemon Blueberry Loaf Cake Recipe

I’ve gotten so many questions about this lemon blueberry loaf cake recipe over the years, so I thought I’d answer the most common ones right here. Hopefully this helps you out!

Can I use frozen blueberries?
Absolutely! Just don’t thaw them first – they’ll turn your batter purple. Toss them straight from the freezer in a little flour before folding them in. That flour coating helps keep them from sinking and bleeding too much.

Why did my blueberries sink?
Oh, that’s a bummer when it happens. Usually it means you either overmixed the batter or the batter was too thin. Tossing the berries in flour before adding them really helps. Also, make sure you’re not overmixing once you add the flour – a few lumps are totally fine.

Can I make this dairy-free?
You bet! I’ve done it plenty of times. Just swap the butter for a good vegan butter stick (not the spreadable kind, it has too much water) and use almond milk or oat milk instead of regular milk. It turns out just as tender and delicious.

How do I get a taller loaf?
This is a common one! First, make sure your baking powder is fresh – it loses its power after a while. Second, don’t overfill the pan; you want the batter to rise, not spill over. And third, make sure your butter is properly softened so you can cream it really well with the sugar. Those air bubbles are what give you a nice tall rise.

Nutritional Information for Lemon Blueberry Loaf Cake

I know it’s tempting to just eat the whole loaf (I’ve been there!), but here’s a rough idea of what you’re getting per slice. Based on the recipe as written, one slice clocks in at about 285 calories, with 11g of fat, 43g of carbs, and 4g of protein. It also has 24g of sugar and 180mg of sodium.

But hey, it’s made with real butter and blueberries, so I say it’s a win.
