Blueberry Granola Crumb Cake (Grain Free)

Blueberry season is my all-time favorite season (which you probably noticed since this is my 4th blueberry recipe in only a few short weeks.) So it was about time that I combined my favorite berry with my favorite baked good: a streusel-topped crumb cake. You read that right gang–it’s a match made in gluten free heaven

This crumb cake is lightly sweet, moist, and fluffy. Plus it’s topped off with the most delicious streusel made with grain-free granola. Words do not do this crumb cake justice, and you’ll be surprised that it’s truly grain and dairy free. I’ve tested it multiple times and given it away to several gluten-eating neighbors who were none the wiser. I really need to make one and keep the slices in my freezer for when my crumb cake cravings hit!

Fresh blueberries vs frozen

I love cooking with in-season fruit, so I prefer using fresh blueberries whenever possible. While you can achieve a similar result with frozen berries, I feel like there’s always a better blueberry taste when you use fresh fruit. You make the blueberry layer in this recipe by cooking down the fruit for a few minutes in a saucepan, so if you need to use frozen berries it will just take a few more minutes to cook. If you have a homemade blueberry compote or jam that you’d like to use up you could sub that in, too.

What you’ll need to make Blueberry Granola Crumb Cake

I’m not a fan of gluten-free recipes that have a laundry list of strange ingredients involved. You’ll only need a handful of ingredients to make this crumb cake, and most of them are Paleo pantry staples, and lower-cost gluten-free flours. And if you don’t have blueberries you can always use a different fruit! And of course, you’ll need some grain-free granola for the streusel.

  • Coconut Flour: I love coconut flour for adding fluff and chew to grain-free baked goods
  • Cassava flour: This helps give a fluffy, gluten like texture without the gluten
  • Tapioca Starch: Adding a bit of tapioca starch gives a bit of flakiness to gluten-free baking.
  • Cream of tartar: this helps make up for the lack of baking powder.
  • Baking soda: for that fluff factor.
  • Coconut Milk: A dairy-free way to add moisture to the batter. You can sub almond milk or another dairy-free milk.
  • Apple Cider Vinegar: I add this to my coconut milk to make a dairy-free buttermilk
  • Coconut sugar: a lower inflammatory sugar option that I use in most of my baking.
  • Coconut oil: You could sub avocado oil depending on what you have on hand.
  • Egg: You can try a flax egg to make these vegan, but I haven’t personally tested that.
  • Blueberries: wouldn’t be a blueberry crumb cake without them! See notes above about frozen blueberries
  • Purely Elizabeth Grain-Free Granola: This is the secret ingredient to making the best granola streusel ever! I use their Coconut Cashew flavor granola.

Tips for making the best grain-free crumb cake:

The great thing about this recipe is that even though it is gluten-free, it’s not finicky or over complicated. You just mix your wet ingredients, add in the flours, and pile everything in a pan with a layer of blueberry filling and streusel! Here are a few tips to make sure your crumb cake is as good as possible:

  • Don’t pack your coconut flour too much when you’re measuring or the batter may be too dry.
  • Don’t forget to line your baking dish with parchment paper.
  • Make sure your eggs are room temperature!
  • Add a bit more coconut milk if the batter is too thick.

 

 

Finding snacks when you eat grain-free can be tough, especially when you’re short on time. For a while, I was limited to trail mix and protein shakes which is great, but that can get a bit old and isn’t very nutritionally diverse. Purely Elizabeth is one of my FAVORITE brands that have ventured into the grain-free space, and I’m so glad they’ve added grain free granola to their line of healthy snacks. And if you’re a fan of oats in your granola, don’t get thrown off by the fact that it’s grain-free. Their products are always flavorful,  and the quality of their ingredients is top notch. From their grain free granola to their bars and now their pancake mixes, I can always count on Purely Elizabeth to keep me fed for a busy day of creating! Their snacks are always on my list when I have a hike or a trip planned, too.

And their Coconut Cashew Granola is my favorite flavor. It pairs perfectly with fruit or smoothies, goes perfect on top of pancakes, and is delicious and flavorful all on it’s own! It’s always in my cupboard and I love sharing it with friends and family–even the ones who can tolerate grains can’t stay away from this granola. Which makes it the perfect addition to the streusel top on this crumb cake that is made for sharing!
