The lemon cake mix gives these muffins great blueberry and citrus flavor, while the sour cream and butter keep them rich and moist. You get balanced flavor, not just a sugar bomb.
Just whisk together sour cream, melted butter, and eggs, then add the lemon cake mix. Fold in fresh blueberries, add sparkling sugar on top if you want, and bake. Easy and delicious!
What you’ll love about these blueberry muffins with cake mix:
Recipe Ingredients:
You’ll need the following ingredients to make these Cake Mix Muffins:
- Sour Cream
- Butter- Salted or unsalted works, whichever you have. Make sure it’s melted but not scorching hot.
- Eggs- Let come to room temp for better mixing.
- Lemon Cake Mix
- Blueberries
- Sparkling sugar
Ingredient Notes:
- Sour cream: Use full-fat sour cream for the moistest muffins. Greek yogurt (plain, full-fat) works great too if that’s what you have on hand.
- Lemon Cake Mix – This adds great citrus flavor that complements the blueberries perfectly. Duncan Hines or Betty Crocker both work well. You can use yellow cake mix or white cake mix if that’s what you have, but lemon is my favorite!
- Blueberries – Fresh blueberries give the best flavor and texture. If using frozen, don’t thaw them first or they’ll bleed into the batter and turn everything purple. Just toss them in frozen.
- Sparkling Sugar – This is totally optional but adds a nice crunch and makes them look bakery-style. Regular granulated sugar works too, or skip it entirely.
How to make muffins from cake mix:
Step 1: Preheat oven to 375°F and line a muffin pan with paper liners, or spray with baking spray. Set aside.
Step 2: In a medium-sized bowl, whisk together the sour cream, melted butter, and eggs until well combined.
Step 3: Add the lemon cake mix to the wet ingredients. Whisk until there are no dry spots of cake mix remaining in the bowl.

Step 4: Using a spatula, gently fold in the fresh blueberries into the batter, making sure they’re evenly distributed.
Step 5: Scoop the cake batter into the prepared muffin pan, filling each one about 3/4 full. Optionally, sprinkle about 1/8 teaspoon of sparkling sugar on top of each muffin for added crunch and sweetness.


Step 6: Place the muffin tin in the preheated oven and bake for 23-25 minutes. The muffins should be golden brown on top, and a cake tester inserted into the center should come out with only a few moist crumbs.
Step 7: Once done, remove from the oven and allow them to cool slightly before serving.

PRO TIP: Don’t over mix once you add the blueberries or they’ll burst and turn your batter purple. Gently fold them in until just combined, a few streaks of batter are fine!
Storage and Reheating:
Storage: Store in an airtight container at room temperature for up to 3 days, or in the refrigerator for up to 5 days. They stay moist and delicious!
Reheating: These are great at room temperature, but you can warm them in the microwave for 10-15 seconds for that fresh-baked taste.
Freezing: Freeze baked muffins in a freezer-safe bag or container for up to 3 months. Thaw at room temperature or warm in the microwave.

Additions and Substitutions:
ADDITIONS:
- Lemon Glaze: Mix powdered sugar with lemon juice and drizzle over cooled muffins for extra sweetness and citrus flavor.
- Streusel Topping: Add a crumb topping made with flour, butter, and brown sugar before baking for extra texture.
- Nuts: Fold in chopped pecans or walnuts with the blueberries for crunch.
- Other Berries: Try raspberries, blackberries, or a mix of berries instead of all blueberries.
SUBSTITUTIONS:
- Sour Cream: Use full-fat plain Greek yogurt or regular yogurt for the same moist texture.
- Cake Mix: Yellow cake mix or white cake mix work great if you don’t have lemon. French vanilla is good too!
- Butter: Substitute with vegetable oil, melted coconut oil, or melted butter (all work 1:1).
- Fresh Blueberries: Frozen blueberries work fine, just don’t thaw them first or they’ll bleed into the batter!

Can you make muffins with cake mix?
Absolutely! Cake mix makes a great muffin base. You just need to add a few ingredients like eggs, sour cream, and butter to get the right texture. Easy muffins and perfect for beginners or having little helpers in the kitchen with you!
Why are my muffins dry?
This usually means they’re over baked. Start checking at 20 minutes, they’re done when a toothpick has just a few moist crumbs, not when it’s completely clean.
Can I use frozen blueberries?
Yes! Just don’t thaw them first. Add them to the batter frozen to prevent them from bleeding purple throughout the muffins.
Can I use yellow cake mix instead of lemon?
Yes! Yellow cake mix, white cake mix, or even French vanilla all work. Lemon just adds nice citrus flavor that complements the blueberries.
Can I make these ahead?
Yes! These muffins are perfect for meal prep. Bake them ahead and store, or freeze them and grab one whenever you need a quick breakfast.
What can I serve with these muffins from cake mix?
These blueberry muffins are perfect with morning coffee or tea. Serve them with scrambled eggs and fruit for breakfast, or enjoy them as a snack with a glass of cold milk! They’re also great warm with butter or a drizzle of honey.

I love that these are made from a lemon cake mix. The sugar on top adds a nice crunch. These will be delicious on Saturday mornings.
These blueberry muffins sound delicious, i love a blueberry muffin that includes sour cream and coarse sugar on top.
This recipe sounds so amazing! I love blueberry muffins love the idea to add a streusel topping.
These look amazing. Going to need to bake these this weekend.
I hope you enjoy them!
Hi, I just made these! Enjoyed 2 with coffee! I even ate them when they were pretty warm, so shouldn’t have been so impatient! Let them rest a 10 minutes so not eating hot blueberries! Very good muffins. I used two different cupcake papers. The tulip papers a little hard to work with the muffin dough, so I’ll use regular liners next time that don’t stick up and get in the way when scooping.
So glad to hear you enjoyed them too!
What is the time difference if making these in large muffin tins
Sam, I haven’t tried it in a large muffin pan, but I would guess to bake it 25-28 minutes.
Easy to make with great taste and texture – thanks for a wonderful recipe
You’re very welcome!!
Absolutely Perfect! I just made these muffins using Sugar Free Cake Mix as I’m diabetic. I used yellow cake mix with lemon zest. I am so pleased. I followed recipe exactly- except for the Sugar Free Cake Mix. I did lightly spray the muffin liners. Next time I might add more blueberries. Thank you so much.
Yay! So happy to hear, thank you for commenting!
These were delicious and easy. I had a box of lemon cake mix to use up and decided I wanted muffins.
I added the zest of one lemon. These were the best lemon-blueberry muffins I have ever had. My husband and friends enjoyed them too!
Hi Debbie! Thank you leaving a comment, I’m so happy to hear this! Your additions sound great!
Hey, I wondering if I can use this same recipe for a layer cake in two pans? I made it as muffins and they were so good!
Hi Val! I haven’t tried it, but I don’t see why you couldn’t adapt it into a layer cake! You’ll need to adjust the baking temperature to 350°F for even baking, and I recommend dividing the batter into two 8-inch round cake pans. Bake the cakes for about 28–32 minutes, or until a toothpick inserted in the center comes out clean or with a few moist crumbs. Let me know if you try it!!
I used a loaf pan and adjusted the time a little longer. I added a teaspoon of lemon extract to enhance the lemon flavor. I topped it off with a lemon glaze too. So delicious. My husband loves it. Great recipe! Cake mix recipes are so easy! Thank you!
These are over the top AMAZING!!!
Thank you for sharing !!
Back making another batch! These muffins are delicious and so easy. Everyone wants more.
Hi Lorraine! I’m so happy to hear! Thanks for you comment!
