The Best Easy Blueberry Breakfast Cake: Fluffy, Moist, and Ready in 35 Minutes

The Best Easy Blueberry Breakfast Cake: Fluffy, Moist, and Ready in 35 Minutes

I’m Jason Griffith, and if there’s one thing I believe about breakfast, it’s that it should be easy, comforting, and taste a little like a hug. This Blueberry Breakfast Cake is exactly that. It’s not an overly sweet dessert cake; it’s a perfectly moist, fluffy, and tender crumb cake, studded with bright, juicy blueberries. It’s simple enough to whip up on a Tuesday morning but elegant enough to be the centerpiece of a Sunday brunch.

Forget the fussy layers and complicated steps. This is a simple, one-pan recipe that is an absolute winner every single time. The secret? A quick toss of the blueberries in flour to keep them from sinking, and a sprinkle of coarse sugar on top for a delightful, crisp texture. You’ll find yourself craving this one all week long.

Why I Love This Recipe

This recipe is a true game-changer for a few key reasons:

  • Speed and Simplicity: It’s a quick, two-bowl method that comes together faster than most pancake batters. You can be enjoying a warm slice in less than an hour, with minimal clean-up.
  • The Perfect Texture: It’s light and airy, thanks to the baking powder, but stays beautifully moist because of the melted butter. The texture is somewhere between a muffin and a coffee cake—pure perfection.
  • Year-Round Delight: While fresh blueberries in the summer are a treat, this cake works just as well with frozen blueberries (no need to thaw!). This means you can have a taste of summer comfort whenever the craving strikes.
  • The Buttermilk Secret: I note in the ingredients that buttermilk is optional, but it takes the flavor up a notch, adding a slight tanginess and making the cake incredibly tender. I highly recommend it!

Swaps and Notes

  • Gluten-Free: You can swap the all-purpose flour for a 1:1 gluten-free baking blend.
  • Dairy: Whole milk is my preference, but any milk (almond, soy, oat) works fine. You can also use oil instead of butter for a slightly moister cake, though butter offers better flavor.
  • Other Fruit: Feel free to swap the blueberries for raspberries, chopped strawberries, or a mix.
  • Buttermilk Hack: If you don’t have buttermilk, add 1 teaspoon of white vinegar or lemon juice to your 21​ cup of regular milk and let it sit for 5 minutes before using.

Instructions

  1. Preheat Oven and Prepare Pan: Preheat your oven to 180∘C (350∘F). Grease an 8×8 inch (20×20 cm) square baking dish, or line it with parchment paper for easy removal.
  2. Mix Dry Ingredients: In a large bowl, whisk together the 121​ cups of flour, 21​ cup of granulated sugar, baking powder, and salt.
  3. Mix Wet Ingredients: In a separate medium bowl, whisk together the egg, milk (or buttermilk), melted butter, and vanilla extract until well combined.
  4. Combine Batter: Pour the wet ingredients into the dry ingredients and mix with a spoon or spatula until justcombined. Do not overmix; a few lumps are okay. Overmixing develops the gluten and can lead to a tough cake.
  5. Fold in Blueberries: In a small bowl, gently toss the 1 cup of blueberries with the 1 tablespoon of flour. This thin coating is key to preventing them from sinking to the bottom. Gently fold the coated berries into the cake batter.
  6. Bake: Pour the batter into the prepared pan and spread it evenly. Sprinkle the top with the optional coarse or brown sugar for extra crunch.
  7. Bake and Cool: Bake for 30–35 minutes, or until a toothpick inserted into the center comes out clean or with a few moist crumbs attached. Let the cake cool in the pan for 10–15 minutes before slicing and serving.

Tips for Success

  • Melted Butter Temperature: Make sure your melted butter is cooled slightly before adding it to the wet ingredients. If it’s too hot, it can scramble the egg when you mix them.
  • The Flour Coat is Non-Negotiable: That tablespoon of flour on the blueberries is crucial. It creates a barrier that keeps the heavy fruit suspended in the batter, ensuring you get berries in every bite.
  • Don’t Overbake: Since this is a breakfast cake, it should be tender and moist. As soon as the toothpick comes out clean, take it out of the oven. Overbaking will dry it out.
  • Buttermilk for the Win: If you have buttermilk, use it. It is naturally acidic and reacts with the baking powder to create a super-light, beautifully tender crumb that is hard to beat.

Serving Suggestions and Pairings

This cake is excellent on its own, but a few simple additions can turn it into a magnificent brunch spread.

Storage and Leftover Tips

This cake is best the day it’s made, but it stores very well.

  • Room Temperature: Store cooled leftovers in an airtight container at room temperature for up to 2 days. Keeping it in the fridge can actually dry it out faster.
  • Refrigerated: If you live in a humid environment or are using fresh dairy toppings, you can store it in the refrigerator for up to 4 days. Let it come to room temperature or warm it slightly before serving.
  • To Reheat: The best way to enjoy leftovers is to pop a slice in the microwave for 10–15 seconds, or wrap it in foil and heat in a toaster oven at 150∘C (300∘F) for 5–10 minutes.
