Whole Wheat Blueberry Crumble Cake

I just made this crumble cake for the first time. A keeper. I was not sure if it would be good because the batter was kind of liquidy but after baking it it turned out perfect. With ice cream is even better. You can also use different nuts and fruit topping for this cake. Very easy and a little bit better for you with the whole wheat flour. I am sure you could modify the recipe and use other type of flours such oat and barley as well.

This is how the cake looked like after taking it out of the oven.


Whole wheat blueberry crumble

Miryam's original recipe

Yield: 8 servings



2 tablespoons of unsalted butter
1/4 cup brown sugar
1/4 cup chopped walnuts
1/4 cup old fashion oats
1 cup fresh blueberries


1 egg
1/4 cup olive oil
1/2 cup sugar
1 cup fat free milk
1 teaspoon vanilla extract
1 1/2 cup whole wheat pastry flour
1/2 teaspoon baking powder
1/4 teaspoon baking soda
Pinch of nutmeg
Pinch of cinnamon



Preheat oven to 350F. Grease and flour dust an 8 inch square baking pan. In a bowl mix topping ingredients except blueberries and set aside.

In another bowl mix egg, oil, vanilla, milk and sugar. Beat until combined. I use a regular whisk. Add flour, baking soda, baking powder, nutmeg and cinnamon. Beat until combine. Pour batter into prepared pan and spread evenly. Scatter fresh blueberries over the top and sprinkle topping over the berries. Bake for 45-55 minutes. Transfer to a wire rack and cool for 15 minutes. Cut into squares and serve. Enjoy

TIP: Adding cinnamon to the crumble topping (like one of my followers suggested) makes a nice flavor addition to this recipe so if you like cinnamon I highly suggest adding it :-)
Thanks for the comment Patti!


  1. Just made this for the second time this morning. This time when I made it I used brown sugar in the batter instead of white and added more cinnamon (love cinnamon!), I also added a bit of cinnamon to the topping. Yum! This is definitely one of my all time favorites! I sent some over to the inlaws and they really liked it too! :)

  2. Oh gosh thanks. It makes me very happy when people try my recipes and likes them. I am glad the in laws were also pleased with it. Definitely adding more cinnamon is the way to go if you are a cinnamon lover :-)

  3. Dear Miryam, THESE ARE SOOOO DELICIOUS!!! I barely ever leave comments, but I just made them and I had to tell you that this recipe is awesome!! I’ve been looking so much for something with blueberries and whole wheat – and this is it!
    Although the recipe itself is very healthy, I made a few small changes to make it even healthier. I used coconut oil instead of butter (same amount) for the topping, and for the batter I used honey instead of sugar. I also smashed one ripe banana and added it to the batter mix. But even without these small changes, this is definitely one of my best desserts! Thank you so much for this recipe!
    Have a nice day,

    ps. have you thought about submitting it to allrecipes.com?? You should :)

  4. I cannot get ww pastry flour where I live. Can I substitute it for whole wheat flour?
