Blueberry Coffee Cake with Brown Sugar-Walnut Crumble
Yay! We're in blueberry season now! Sweet, plump, and full of flavour; these little berries are one of my favourite fruits.
I have been using blueberries in many recipes all summer long as well as eating them by the handful as a healthier snack. These berries are full of antioxidants as well as vitamins C and K, but mostly they are just plain tasty.
I think that blueberries are even tastier when scattered in a yummy coffee cake. Yes, it is not really healthy in cake form, but everything in moderation, I say.
Plus, it's so shareable and easy to put together and most ingredients are likely already in your pantry; if not, they can be easily found at any grocery store.

All the ingredients for the cake! Amounts listed in the "Ingredients" list below. The crumble ingredients are not shown.

Once the batter is prepared, pour it into a baking pan greased and lined with parchment paper (it's easier to take out the cake whole that way). Top with more blueberries and then with crumble (I'm halfway there in the picture).
Bake at 375 degrees F for 35-40 minutes. Look at that crunchy sweet crumble with blueberries peaking out on top!
Let it cool before removing from the pan.

This cake is is soft, fluffy, and loaded with delicious fresh blueberries. As the blueberries are baked, they soften and juices release. There are bursts of wonderful blueberry flavour throughout the cake. The pretty blue colour is swirled in different patterns with each piece cut.
The crumble (or crumb topping)on top of the cake is sweet from the brown sugar and crunchy from the chopped up walnuts. If you have pecans on hand, they will work just as well. There is a mild hint of cinnamon flavour that goes so well with the flavours of the cake and crumble.

Once cooled, slice the cake into as many pieces as you want and serve. It goes perfectly with a fresh cup of hot coffee, or if you prefer, a cup of tea or a glass of milk for breakfast. It's also great as an after-dinner dessert or as a snack.
I hope you enjoy this recipe!

This is perfect for my morning coffee fix.. thanks for the recipe.
You're welcome Calleigh!
What a delicious afternoon coffee cake! I love the streusel topping and the inclusion of delicious blueberries that I'm sure explode with flavour. Any chance you can drop one off - that sounds just like what I need right now!
I wish I could send it your way! Thanks Amanda!
Wow this is gorgeous! Beautiful presentation! ๐ will this work with using the egg substitute?
I believe that you can. A quarter cup of banana, unsweetened applesauce, or flax seed mixed with water are good subs. It will change the flavour slightly though! Thanks Gina Marie!
It's been soooooo long since I last had coffee cake that I've absolutely got to give this recipe a try ASAP! Love how the colours of the blueberries seep into the cake. It looks so pretty!
I love the blueberry swirls in the cake too! Thanks Nicola!
I love berries in cakes, that crumbly topping looks so delicious!
It's so good! Thanks Emily!
Yum!! That looks heavenly! I love everything related to coffee and blueberries. I have to try this cake. I pin it for later. Thanks for sharing your recipe.
Thanks Silvia!
I just made it, very delicious, itโs a bit moisty, which I think is for fresh blueberries. Thanks for great recipe.
You're welcome Maryam! I'm glad you enjoyed it.
I took this to a ladies brunch - it was a big hit! Very moist and flavorful. I love the topping!!!
Thank you so much Denise! I'm happy to hear that this was a hit.
YAY. For this recipe !!! It's The Best cake ever. And I bake a Lot!!!! It reminds me of Drake's coffee cake w blueberries. If u remember those l.o.l...This is my second time making it. Everyone Loved it ๐
Thank you Michelle! This makes me so happy to hear! ๐
Is there a way to make these eggless? What should I substitute it with to ensure itโs as moist as an egg one?
Hi Shagun! I've always used an egg for this recipe, but if you are looking for substitutes, you can always try using half a banana or a 1/4 cup of applesauce instead.
Looks delicious ๐ can't wait to try it. Can you substitute the blueberry for other fruit or even dry fruit or chocolate chips??
Yes, you can sub with other berries or chocolate chips.
Sooooooo so good! I doubled the crumb topping because itโs my favorite part haha! Just had to bake a bit longer to account for the increase in thickness. Will definitely be making again.
The topping is my favourite part too! Thanks for the review!
