Lemon Blueberry Cake with Buttermilk Icing

Lemon Blueberry Cake; lemons and blueberries living harmoniously in a cake-y loaf. Oh yeah and smothered in a tangy buttermilk icing.

Are you thinking what I’m thinking?

Are you thinking that you couldn’t possibly be sick of yet another lemon-blueberry recipe? Because I know I’m not. I just can’t get enough of those two together! Somebody explain to me why that is? I need to form a support group.

Hi my name is Laurie and I’m a lemon-blueberry junkie.

I’m especially fond of whenever blueberries are baked into a moist {sorry had to} cake-y loaf and then coated in a thick layer of icing. I’m not sure what I love more… the Lemon Blueberry Cake or the icing. It’s a tough call… so to be fair I won’t choose sides. Because the bread would be grand all by itself, but the icing takes this loaf overboard and me along with it.

Got lemons? Well then zest about two tablespoons worth. Which depending on the size of lemons you have… it’s roughly two to three. Then you’ll have to juice them and and strain the seeds and measure out 3 tablespoons. Phewwww!

Crack two eggs into a large mixing bowl.

Add in the cup of granulated sugar.

Drizzle in a third cup of melted and cooled butter.

Then lastly add in the lemon juice.

Whisk to combine and set aside.

In a different bowl measure out the all purpose flour, add in the baking powder and salt… stir those to combine.

Gradually add the dry ingredients into the wet.

Then, alternately adding in the milk. I do it in thirds. Dry, milk, dry, milk, dry, milk… you get the picture.

Always go through the blueberries and check for stems. They’re slippery buggers and nobody wants to bite into a stem.

Next, toss the blueberries in with a little {like a teaspoon} of flour. The flour helps them from sinking to the bottom of the cake, thank you Ina Garten.

Then add them into the batter.

Along with all that zest…

Next, stir the batter very c-a-r-e-f-u-l-l-y.

Then spray and lined an 8×5 loaf pan. You know how I love my Misto… but any healthy spray, thin coating of coconut oil or butter will do.

Next, pour the cake/bread/loaf batter into the prepared pan and slide the pan into a preheated 350 degree pan for 55 to 60 minutes. Ya know how every oven is different… so be sure to check on this baby. The tops and edges should be a light golden and if you inserted a tester it should come back clean.

Then let the loaf cool in the pan for 10 minutes and then carefully, run a butter knife along the edges and using the parchment paper handles, remove it from the pan to a wire rack to finish cooling.

Eeek buttermilk glaze! This is the kind of glaze that hardens as it cools. So when you go to slice into the loaf… it crackles. Heaven. All you need is one cup powdered sugar and two tablespoons butter milk… that’s all folks.

Next, add the buttermilk to the sugar.

Then whisk until there are ZERO clumps of sugar and it’s thick and glorious.

Lastly, pour it all over your cooled Lemon Blueberry Cake and with an offset spatula {or a butter knife} schmear it all around.

Drips are everything. Oh and save the parchment to lick the remaining icing off because it’s the adult version of the cookie-batter beater. Wait, I still lick the beater. Oh well you should do it anyway.

As you can see I couldn’t wait for the icing to cool completely. What can I say? I’m a total sucker for slightly warm cake and slightly hardened icing. Don’t be like me or rather do be like me and dig in!

    I know what you mean about “wait for the item to cool before slicing”….and risk it not being warm??!! That’s CRAZY talk….we made Chocolate Chip Zucchini Bread on Friday, and just had to slice it while it was still too hot….but SO worth it for the melty chocolate chips inside…yummy!!

    Looks delicious – just put mine in the oven! Two small things: you have 1.5 cups of flour listed in the ingredients list, but only mention 1 cup in the directions, and you listed the butter as an ingredient, but don’t mention where to add it in.

    Can’t wait to eat this when it comes out of the oven!

    Hi Laurie! How did I not comment on this loaf already? This is perfectly one of the most beautiful loaf cakes I’ve ever seen. The pictures… speechless. Like, probably the prettiest post I’ve ever read! That buttermilk icing looks and sounds out of this world, and what a nice compliment to the cake! I love the combo of lemon + blueberries, too. I am saving this bad boy because I must remake it sometime!

    Kari@Loaves and Dishes — August 15, 2012 at 2:38 am

    The reason we don’t get sick of another blue berry and lemon recipe is because they are so perfect together. So why mess with perfection… unless it’s to add a buttermilk icing of course.

    Love this loaf! Wow, it looks so moist with such intense blueberry… And the glaze – I’m drooling! I’m featuring this post in today’s Food Fetish Friday (with a link-back and attribution). I hope you have no objections and thanks for sharing such amazing creations…

    Oh boy, I love that lemon-blueberry combo, too, and this bread looks divine! I do a simple, yet delicious, lemon-blueberry pie, though this bread needs to be a part of my every day life.

    This is fab, although in my kitchen I was following the written-out method and everything went in the oven, and I still had the butter left over! Catastrophe round 1. Round 2 was wonderful. So the buter is missing from the full recipe….

    I just made this and it turned out great! I loved the idea of lemon and blueberry and I think the dessert tasted great! The cake went perfectly with the icing. It was a great balance of citrus and sweet. It wasn’t too sour at all and I enjoyed every bite of it. Normally I don’t like homemade frosting because it just tastes like powdered sugar and I thought that might be the case with the icing since it was pretty much just powdered sugar but I honestly didn’t notice a strong powdered sugar taste once it was combined with the lemon blueberry cake. It was all super good and I totally recommend this recipe.
