This is the perfect berry-filled pound cake for any and all occasions. Bonus? It’s simpler to make than you’d think, and so very pretty…with very little effort.

Happy last Friday of May – happy almost June! You guys, I have to admit, I am feeling excited. June is so very close and things are starting to feel summery. It’s a fun time of year. We have three months of nice weather, amazing summer produce, and lots of summer baking to look forward too.
But right now, what I’m most excited about is this simple loaf cake, which is somewhat shocking to me. One, because there’s no chocolate involved…which is usually a must for me when it comes to cakes. And two, this is a loaf cake, not a layer cake. We all know how much I love a good layer cake, but I challenged myself to create a simple loaf style pound cake as a change of pace. It’s something I’ve never created before and I love creating new to me recipes.
Jumping right into the details today, because well, I want us all to do a little Friday night baking…it’s my favorite night to bake!

As I mentioned above, I wanted to create something fresh, new, and different. I’ve never shared any kind of pound cake, or loaf cake for that matter, so I decided a lemony blueberry cake was the perfect fit. Fresh summer flavors in a simple loaf style cake.
I recently stocked up on plenty of fresh blueberries, so I knew I was good to go there. Additionally, I had plenty of fresh thyme in the fridge from my last herb order. I decided to put the two together and create a pound cake bursting with berries and hinted lightly with floral thyme and fresh lemon.
It was perfect. Bursting with flavor and juicy berries…and best enjoyed with a scoop of ice cream. Or maybe a little homemade whipped cream plus a warm cup of coffee. Perfect Sunday morning brunch, afternoon snack, or late night dessert. You can’t go wrong.

It’s quick, easy, and so simple.
Cream some butter with lots of lemon zest and a touch of sugar. Then add eggs and sour cream.
Now, the sour cream is KEY. You can also use Greek yogurt, but I’ve decided that sour cream will give you the best flavor and the most amount of moisture too. This is my first time baking with sour cream, but it will not be my last. It’s a game-changer and I’m just a little bit obsessed.
Once all the wet ingredients have been mixed. Simply beat in the flour, baking powder, and a pinch of salt. Then stir in lots of blueberries.

Because I LOVE a jammy cake and a mix of fresh berries to sweeten the concentrated jam. It’s a winning combination that never gets old.
So, layer half of the batter into a loaf pan, next swirl in a tablespoon or so of sweet blueberry jam. Spoon over the remaining batter, then add one more swirls of jam, a small handful of berries, and a sprinkling of sugar on top to finish.
At this point, it’s time to bake. Like most pound cakes, this takes about an hour in the oven…which is a long while. But I promise, the wait will be worth it!

The glaze is where the thyme comes in.
First things first, please do not let the use of thyme scare you away. If you’ve never tossed thyme in with your berries, now is the time to start. It’s not an intense flavor, but it lends a really nice floral touch. I love the combination of lemon, thyme, and blueberries. It’s a simple ingredient to toss into the mix but adds so much.
That said, you are of course welcome to omit the thyme from the cake. It’s totally up to you, but I love the herbal addition.
The rest is simple. Mix powdered sugar with lemon juice and that thyme…and that’s your glaze.
Simple. Simple.

Once the cake has cooled, drizzle the glaze over the top, slice, and enjoy!
Every bite is bursting with sweet blueberries, hinted with lemon and thyme, and perfectly sweet too.
Of course, I highly recommend you serve each slice with a scoop of vanilla ice cream. It’s the only way to really enjoy a slice of berry-filled cake.

You can really use whatever berry you love or have an abundance of in the fridge or in the freezer. Blackberries, raspberries, or a combo of your favorites…all will work, and all will be delicious.
If you don’t cook with sour cream, try using plain Greek yogurt. That works nicely too!
So make this today, tomorrow, this weekend, and from now until the start of fall. Fingers crossed that this blueberry cake will become your new “back pocket” summer cake recipe. So, with that, I will leave you with this yummy, but simple loaf style blueberry lemon cake.
Happiest (almost June) baking to you all! Hope you guys enjoy this cake as much as I do!

Thank you so much for letting me know! xTieghan
So so good! So easy to make! Used 1 tspn of dried thyme for the dressing instead of fresh, but it still worked well. The cake has frozen well, too.
Thank you Cait! xTieghan

Going to make this today! I don’t have a 9x5inch loaf pan, only mini loaf pans. Would the cooking temp and time be the same?
Hi Jordan,
Keep the same temp but I would reduce the baking time by 10-15 minutes, just be sure to keep an eye on them. I hope you love the recipe, please let me know if you have any other questions! xTieghan
This recipe was straightforward and so delicious. I skipped the glaze and it is still awesome. I love the texture and that it is not too sweet – reminds me of my favorite blueberry muffin. Plus fresh blueberries in June! This is something I will make and share with friends. Thank you for sharing!
Amazing! Thank you for trying this recipe, Laura! xTieghan
Just made this and popped it in the oven. When I added the Greek yoghurt (didn’t have sour cream) the mixture went really lumpy, I beated it for a while but the lumps stayed. I just carried on so hopefully it turns out okay. Thanks for the recipe 🙂
Hi Emily! I hope this turned out amazing for you! Please let me know if you have any questions! xTieghan
Such a great recipe! I made it into 12 muffins and it worked very well. The lemon thyme glaze really is the perfect addition.
Thank you Sammy!! xTieghan
Easy to make and so pretty. It is bursting with color and flavor. I accidentally used finely chopped fresh rosemary leaves instead of thyme and it was so fragrant and delicious! I cant wait for it to cool to glaze it!
Thank you so much Evelyn! xTieghan
Made this tonight and it was delicious! I used strawberry jam (because it was all I had) but it didn’t overpower the blueberries at all. Thanks!
Thank you Brittany! xTieghan
I made this yesterday and it is completely delicious! I love the thyme in the icing, adds such a lovely fresh flavour!
Thank you Lucy! xTieghan
Delicious and moist! We didn’t have sour cream on hand, so did the greek yogurt swap – will have to try it again with sour cream next time. We also skipped the glaze, just to cut back on sugar and to be honest, the loaf was definitely sweet enough without.
One question though – we were hoping it would be more lemon-y and perhaps that’s because we didn’t do the lemon juice glaze. But do you have another suggestion for making it a bit more lemon-y and tart? Thought about putting lemon juice in the batter, but didn’t know if that would throw off the proportions or how much would work! Thanks in advance!
I made this for the first time this weekend and it was delicious. My family ate the entire thing in one day. I will definitely be making this again!
Thank you Zoey! That is so amazing to hear! xTieghan
