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.

To Make This Lemon Blueberry Cake You Will Need:

for the cake:

  • eggs
  • granulated sugar
  • unsalted butter
  • freshly squeezed lemon juice
  • unbleached all-purpose flour
  • baking powder
  • kosher salt
  • whole milk
  • blueberries
  • lemon zest

for the glaze:

  • powdered sugar
  • buttermilk

Preheat your oven to 350° spray and lined an 8×5 loaf pan with parchment.

Crack 2 eggs into a large mixing bowl.

Add in 1 cup of granulated sugar.

Drizzle in 1/3 cup of melted and cooled butter.

Then lastly add in 3 tablespoons fresh squeezed and strained lemon juice.

Whisk to combine and set aside.

In a different bowl measure and add 1-1/4 cups all-purpose flour, add in 1 teaspoon baking powder and 1 teaspoon salt. Stir those to combine.

Alternate adding some of the dry ingredients into the wet.

Then, alternately with 1/2 cup milk. I do it in thirds. Dry ingredients, milk, dry ingredients, milk, dry ingredients, milk… you get the picture.

Go through 1 cup blueberries and check for stems.

Next, toss the blueberries in with 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 2 tablespoons lemon zest.

Next, stir the batter very carefully to avoid smashing the blueberries.

Next, pour the cake/bread/loaf batter into the prepared pan and slide the pan into a preheated 350° 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.

Make the buttermilk glaze!

This is the kind of glaze that hardens as it cools. So when you go to slice into the loaf… it crackles.

Next, add 2 tablespoons buttermilk to 1 cup powdered 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) spread 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!
