Ingredients You Need

Let’s talk about what makes this Blueberry Crumb Cake downright irresistible! Here’s everything you’ll want to grab before we start mixing up the magic.

Ingredients for Blueberry Crumb Cake including flour, sugar, butter, blueberries and spices
  • 2 cups all-purpose flour – This is the sturdy base for our cake. No worries if gluten-free flour is what you have on hand; I’ve tested swaps that still deliver on texture without losing that crumbly love.
  • 1 cup granulated sugar – Sweetness is key here, but I always stick with granulated to get that classic blueberry coffee cake feel.
  • 1/2 cup unsalted butter, cold and cubed – This crumb topping recipe depends on cold butter to achieve that perfect crunch!
  • 1 cup sour cream – This adds moisture and tang to the Blueberry Crumb Cake; you can substitute Greek yogurt if you’re in a pinch.
  • 2 large eggs – The glue that holds everything together.
  • 2 teaspoons baking powder – For that gentle lift we all want in a fruit crumb cake.
  • 1/2 teaspoon baking soda – Enhances the rise and keeps the crumb tender.
  • 1/4 teaspoon salt – Trust me, it brightens the blueberry dessert cake flavor like nobody’s business.
  • 2 cups fresh or frozen blueberries – These jewels are the star of the show! Frozen works great too, just don’t thaw them before mixing.
  • 1 teaspoon vanilla extract – For a warm, comforting note.
  • 1 tablespoon lemon zest – I love the zing it gives to my Blueberry Crumb Cake for that extra kick.

For the crumb topping:

  • 3/4 cup all-purpose flour
  • 1/2 cup light brown sugar – This adds a deeper sweetness to the crunchy bits.
  • 1/2 teaspoon ground cinnamon – Cinnamon in the crumb topping recipe creates a warm, classic vibe.
  • 1/4 cup cold unsalted butter, cubed

You can grab every one of these at your regular grocery store—that’s part of the charm. Nobody wants to hunt down obscure ingredients during the week! For busy nights, I like to prep the crumb topping ahead and keep the blueberries ready to toss in last minute.

If you’re feeling bold, add a sprinkle of toasted almond slices on top. I’ve found they add that perfect nutty crunch to complement the sweet and tangy blueberry dessert cake. Seriously, this Blueberry Crumb Cake ingredient list is all about bold flavors that actually work together!


Let’s Make Some!

Ready to make your kitchen smell like a blueberry coffee cake dream? Here’s how we bring this Blueberry Crumb Cake to life, step-by-step.

  1. Preheat your oven to 350°F. Grease and flour a 9×9-inch baking pan, or line it with parchment paper so nothing sticks. This is where the magic starts happening!
  2. Mix dry cake ingredients: In a big bowl, combine 2 cups flour, baking powder, baking soda, and salt. Stir it up until evenly mixed.
  3. Beat the wet ingredients: In another bowl, whisk together sugar, sour cream, eggs, vanilla extract, and lemon zest until smooth. The blend of tang and sweet here is what makes this blueberry dessert cake stand out.
  4. Combine wet and dry: Slowly add the dry ingredients to the wet, folding gently until just combined. Don’t overmix! Your batter should be nice and thick but not tough.
  5. Fold in blueberries: Gently fold your berries into the batter, making sure they’re distributed well but not smashed. Juicy pockets of blueberry in every bite—yes!
  6. Make the crumb topping: In a separate bowl, mix the flour, brown sugar, and cinnamon. Add the cold, cubed butter. Use your fingertips or a pastry cutter to blend until you get crumbly bits about the size of peas.
  7. Pour batter into the pan: Spread it out evenly with a spatula, then sprinkle the crumb topping generously all over.
  8. Bake: Slide your blueberry crumb cake into the oven for about 45-50 minutes. Keep an eye on it towards the end—when the top is golden brown and a toothpick inserted comes out clean around the edges, it’s ready.
  9. Cool and enjoy: Let it cool for at least 20 minutes before slicing. This step lets the crumb topping set perfectly and keeps the inside moist and tender.

Your kitchen should smell absolutely incredible right now. I love it when that aroma fills the whole house—it’s my signal that happiness is on its way! Don’t worry if your crumb topping looks a bit crumbly or uneven—that’s part of the charm and shows you nailed that crumb topping recipe.

In my kitchen, this Blueberry Crumb Cake usually takes about an hour start to finish—perfect for a weekend brunch or an indulgent weeknight dessert. While it’s baking, have a peek at some other bold flavors, like the White Chocolate Blueberry Cheesecake that pairs beautifully with this cake’s fruity profile.

FAQs:

Will kitchen newbies succeed with this Blueberry Crumb Cake?
Absolutely! I’ve designed this recipe to be fuss-free and forgiving. Follow the steps, and you’ll get a moist, flavorful cake that’s ridiculously satisfying. You don’t need special skills—just a whisk and some love.

What if I mess up my Blueberry Crumb Cake?

Wrap your leftover slices in plastic wrap or keep airtight in the fridge for up to three days. Reheat gently in a toaster oven to bring back that crumbly crunch.

Can I swap ingredients for dietary needs?
Yes! I’ve swapped sour cream for Greek yogurt and used gluten-free flour blends with delicious results. For dairy-free, coconut oil works well in the crumb topping. See the helpful hints in the Blueberry Crumb Cake Recipe – Entertaining with Beth for more ideas.
