Blueberry Cinnamon Crumb Coffee Cake
This Blueberry Cinnamon Crumb Coffee Cake didn't last long in our house. Colt and the kids all decided they needed 2 pieces for dessert last night and we aren't talking little itty bitty slices. We are talking about full-sized huge slices Colt had cut.

As if Colt hadn't had enough coffee cake he was standing in the kitchen at 2 am eating out of the pan, I may or may not have joined in on a few bites..  I decided to add a cinnamon swirl to the middle of the cake to make sure there was a little bit of cinnamon crumb topping in every bite along with the blueberries.

It doesn't get much better than this my friends.

Blueberry Coffee Cake Brown Sugar Crumb Topping
Mix together 1 3/4 cups Brown Sugar, 1/4 cup Flour and 1 1/2 teaspoons Cinnamon. This can be done by hand or in a mixer.
Coffee Cake Cinnamon Sugar Crumb
Add 6 tablespoons Cold Butter, Cubed. If using a mixer mix on low speed until crumbly or cut in using a pastry cutter.

Mixture should form large crumbs when pressed together.
In a large mixing bowl cream 3/4 cup cold Butter. Slowly add 1 1/2 cups Granulated Sugar while mixing on medium speed. (The cold butter helps add volume to the batter and holds it's texture better making for a lighter cake.)

Scrape sides of bowl and add 4 eggs one at a time, beating well between each addition. Scrape sides of bowl between each addition. Then add 2 teaspoons Vanilla and mix well.

Add 3 cups All-Purpose or Whole Wheat Pastry Flour 1 cup at a time alternating with 1 1/2 cups Sour Cream (1/2 cup at a time.)
I've used both types of flour and you can't tell the difference between the whole wheat pastry flour and all-purpose in this recipe.
Blueberry Coffee Cake Batter with Sour Cream
Mix on low speed between each addition until just combined, being careful not to over mix.
Blueberry Coffee Cake Cinnamon Swirl Crumb stir in Bluberries.

Blueberry Cinnamon Swirl Crumb Coffeecake


  1. Oh WOW - this looks SO beyond delicious!! It reminds me of a coffeecake my family used to eat at our favorite breakfast spot, which, unfortunately, has cut some corners in recent years and the coffeecake pales in comparison to its former self. I'll have to try this and see how it compares!

    1. I hope you like it just as much as your favorite breakfast spot! It was a hit in our house!

    2. I finally bought some blueberries going to make this by the weekend, looks yummy!! Thanks

  2. Mmmm that crumb looks sooo yummy! Definitely wouldn't mind having this in the morning with my coffee :)

    Happy Blogging!

  3. I have yet to bake up anything with blueberries this summer! Bill is hankering for a pie, but I'd much rather make your wonderful coffee cake.
    PS. I made your banana cream pie and Bill was in heaven! It was SO good!

    1. Thanks so much Liz! I'm glad that Bill enjoyed the Banana Cream Cheesecake! It's my husbands favorite too!

  4. I love blueberry coffee cake! This looks insanely delicious!

  5. thanks for sharing this great recipe! love the flavour combination.. definitely a recipe i will be trying!

  6. That is dreamy! I love blueberries and I love cinnamon too. This is SO mine!

  7. I love that crumb topping! This cakes looks so moist and delicious!

  8. Boy do I LOVE blueberry cakes! That crumb topping looks so, so good. Sort wish I had some right now!

  9. Looks amazing. Can i substitute blueberries for strawberries?

    1. Sorry I missed your question! Yes you could try to sub with strawberries you might want to reduce the fruit a little as the strawberries have a tendency to be juicy or Raspberries would work in equal amounts!

  10. Delicious made it for a bday party and everyone loved it !

  11. I made this several days ago for my boyfriend's work buddies. They all absolutely loved it, and now they're all asking for the recipe! This one's a keeper, thank you. :)

  12. This is in my oven right now. Huge mess to make but I cannot wait to eat it. Already looks and smells delish. Note to self--not even close to fat free. Lol

  13. If you like Sugar this one's for you. 2 Cups brown sugar?????? Everyone took one bite and that was all. Maybe I'll try with only 1/2 Brown sugar. Other than that cake tastes OK. No winner.

  14. Made this tonight. Oh my goodness, so very good! My kids couldn't even wait for it to cool down!

    1. I'm so glad your families enjoying it as much as ours does!

  15. Absolutely fabulous! Baked it tonight. Thank you for a great recipe 👏🏻🍰

  16. Could you prepare this the night before and bake it in the morning, do you think?

    1. I would bake it at the time of making it due to the baking soda and powder being activated once mixed with the wet ingredients. It stores really well and could be reheated until warm. I hope that helps! Thanks, Serena

  17. Do you use salted or unsalted butter?

    1. Salted, if you use unsalted you will need to add more salt.

  18. Ingredients call for 3 tbl all purpose flour & then list another 1 1/2 tsp cinnamon & 6 tbl cold butter. Are these in addition to the first cinnamon & butter listed after the 1 3/4 c. brown sugar?

    1. Hi Lexie! I'm not sure how that happened but that is an error that must have happened during that last update! I will fix it! Thanks, Serena
