Celebrating the weekend with this sweet Swirled Blueberry Lemon Thyme Cake. Perfect for summertime baking. Sweet lemony sour cream cake swirled with a mix of fresh blueberries and blueberry jam. This cake is mouthwatering and oh so delicious. Every bite is layered with fresh berries, jam, and hints of lemon. Finish this simple cake with a lemon-thyme glaze that’s unique and delicious. 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!

I just baked two cakes, back to back. In both times, the amount of batter was about half of what you’ll see on the pan (before baking), so the cake came out only about half as tall. Why did that happen, I would love to know!
Hi Luna,
Did you adjust the recipe at all? It is hard for me to say what happened without knowing. Also this recipe is only enough for one loaf pan, so if you split it into 2 that is your issue. Please let me know how I can help! xTieghan
I made this loaf cake today and couldn’t get over the flavor – probably my favorite bread ever! This will become a staple recipe in our household. I love your work and the content you share, keep it up!
Thank you so much Hannah! xTieghan
I made this for brunch.. it was so yummy! Went great with my coffee. Thank you for the recipe!
Thank you so much Misty! Ugh, now I am craving this with some coffee haha! xTieghan
Awesome recipe! I just stumbled upon lemon thyme the other day and had to try this. And it went great! So easy and so good.
I just think the batter could be a little more to fill a standard loaf pan, but maybe I just calculated the metric amounts wrong. With about 350g flour it should be perfect!
Thank you so much for trying this Ruben!! I am really glad it turned out so well for you!! xTieghan
So yummm!!! Was really moist and was such an easy recipe to follow AND looked amazing:) Thx for sharing another delicious recipe!
So gooood!! Just as tasty as it looks, was super moist and such an easy dessert to make as well:)
Thank you Katie! That is so amazing to hear! xTieghan
I’m not gonna lie…this is my favorite place to visit on the interweb. It is my first stop when looking for inspiration and ideas.
I substituted huckleberries for the blueberries and this was amazing. I also used lemon thyme. I really appreciate all that you contribute.
Thank you so much Darren! That is so great to hear! xTieghan
Made this when you posted it, absolutely delicious and super fluffy. As with all your recipes, this is another winner!
That is so amazing to hear! Thank you so much Maria! xTieghan
The pictures look so great! I wish I could click such pictures. Really looking forward to trying to out the recipe just so I can get such pics for my Instagram 🙂
Haha that is so great! It honestly takes time and a lot of practice, but I am sure you’re doing great! Thank you Abigail! xTieghan
Make this today, SUBLIME. I substituted almond extract for vanilla, because i was out. It worked perfectly, just had a sweet almond undertone. Just make sure if you do swap, that you use half the amount of almond than vanilla. Its stronger.
Try it!
Thank you so much! I am so glad this turned out so well for you! xTieghan
wow i have already made this twice because it is that good
Love that! Thank you so much Lauren! xTieghan
We have friends raving about your website and book and wow I can see why. Over the last 3-months I have made meals/desserts/drinks solely from your website/book and everybody is hooked! During this time of quarantine, it’s offered restaurant style foods/drinks and has now turned into a daily ritual to venture through your recipes! Absolutely obsessed! You are such a talented being!
This recipe is the perfect summer sweets! We tried this with or without the icing and it’s pure bliss
Hi Sabina! Aw this is so sweet to hear! I am so glad my recipes have been getting you all through quarantine and I hope you continue to love them! Thank you so much! xTieghan
Can you substitute regular flour for almond or coconut flour? Trying to make a gluten free option but don’t have GF flour on hand.
Love this!! How can I modify to make muffins?
Hi Carol,
I would just reduce your baking time to 20-25 minutes but just keep an eye on them! I hope you love the recipe, please let me know if you have any other questions! xTieghan
This was absolutely amazing. It’s so moist and sweet, you can’t go wrong. Great for a summer’s day and I definitely plan on making this again! I just found her page on Instagram recently and I’m so impressed. Yum!
Thank you Melissa! I am really glad this recipe turned out so well for you! xTieghan
