Blueberry Crumb Cake

By Angela Sellari Jump to Recipe

In the mood to indulge sans sugar? With its crisp topping and pops of juicy berries, our delectable Blueberry Crumb Cake will surely hit the spot.

We all know sugar should be consumed in moderation, but what’s one to do when sweet cravings hit and indulging yet again really isn’t an option? Why make this blueberry crumb cake, of course! I’ve always loved crumb cakes, and since I had just come back from the market with a few baskets of fresh blueberries, making this cake was a no-brainer. I’ve made a version with real sugar before, but after a weekend filled with my share of pastries (from that thick slice of carrot cake with coffee I had for breakfast on Saturday morning to those chocolates we ended dinner with on Sunday), it seemed sensible to make a sugar-free version. And believe me when I tell you that you won’t be missing out on a thing!

Studded with plump, juicy berries and made with zero-calorie sweetener, this moist, tender-crumbed cake is perfect as a snack, dessert, or even for breakfast. The crisp, buttery topping is made with a dash of cinnamon, which complements the fruit’s natural sweetness and adds a touch of aromatic goodness. Just goes to show that thanks to zero-calorie sweeteners, we can definitely have our cake and eat it, too!

Make it your own

For added fiber and to make this cake just a little more wholesome, you might want to try making it with white whole-wheat flour instead of all-purpose flour. When making the crumb topping, you could even replace some of the flour with rolled oats. Not only will it add extra fiber, but it will give the topping a denser, chewier texture.

Almonds and blueberries are an excellent pairing. Use almond extract instead of vanilla extract, and sprinkle the cake with two tablespoons of almond slivers before baking. Want to give this cake a little twist? Try making it with fresh raspberries instead of blueberries, and add two tablespoons of finely chopped pistachios to the crumb topping.

How do I store leftovers?

The cake can be kept in an airtight container at room temperature for up to 2 days or in the fridge for up to 5 days. Bear in mind that storing it in the fridge will render its crumb a little denser. For longer storage, freeze in a freezer-safe container or Ziploc bag for up to 3 months.

Serving suggestions

Serve this cake for breakfast or as a snack with this energizing (and sugar-free!) Coffee Smoothie. For dessert, plate up a warm slice and top it with either a good dollop of Whipped Cream (use a sugar-free sweetener) or our delicious Keto Ice Cream.
