There’s something about those late summer afternoons when the sunlight dapples through the leaves, and a bowl of fresh blueberries sits on the kitchen counter, begging to be used. I remember the first time I made this Easy One-Bowl Loaded Blueberry Cake—it was one of those unexpectedly quiet moments when I just wanted something sweet but simple, nothing fussy.

What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most of these are pantry staples, and the fresh blueberries bring that seasonal pop.

• All-purpose flour – 2 cups (240 g), for the base structure
• Baking powder – 2 teaspoons, to help the cake rise beautifully
• Salt – 1/2 teaspoon, balances the sweetness
• Granulated sugar – 3/4 cup (150 g), the perfect amount for sweetness without overpowering
• Unsalted butter, melted – 1/2 cup (115 g), adds richness and moisture
• Large eggs – 2, at room temperature for better mixing
• Vanilla extract – 1 teaspoon, for that warm, comforting aroma
• Whole milk – 3/4 cup (180 ml), but feel free to use dairy-free milk if preferred
• Fresh blueberries – 1 1/2 cups (225 g), gently folded in to keep them plump and juicy
• Optional: Zest of one lemon for a fresh twist that brightens the flavors

For best results, choose firm, ripe blueberries—if using frozen, don’t thaw them fully to avoid color bleeding. I often grab organic berries from my local farmer’s market when they’re in season. Also, if you want a gluten-free version, swapping the all-purpose flour with a 1:1 gluten-free blend works well here.

Equipment Needed

One of the reasons this cake is such a joy to make is the minimal equipment required. You really just need a few basics:

• A large mixing bowl (big enough to hold all ingredients comfortably)
• A whisk or wooden spoon for mixing (I prefer a wooden spoon for better control)
• A 9-inch (23 cm) round or square baking pan, greased or lined with parchment paper
• Measuring cups and spoons for accuracy
• An oven thermometer (optional but handy to ensure the right baking temp)

If you don’t have a whisk, a fork or even a sturdy spatula can do the job. And if your pan is a little smaller or larger, just adjust the baking time accordingly—the cake should come out golden and springy to touch. I learned the hard way that a non-stick pan can sometimes brown the bottom too quickly, so I prefer a well-greased, heavier pan for even baking.

Preparation Method

1. Preheat your oven to 350°F (175°C). Prepare your baking pan by greasing it or lining with parchment paper. This step is crucial to prevent sticking and ensure easy removal.
2. In your large mixing bowl, combine the dry ingredients: 2 cups (240 g) all-purpose flour, 2 teaspoons baking powder, and 1/2 teaspoon salt. Whisk these together to distribute evenly—this helps the cake rise uniformly.
3. Add the sugar: Pour in 3/4 cup (150 g) granulated sugar and gently mix it with the dry ingredients.
4. In a separate small bowl or measuring cup, whisk the wet ingredients: 1/2 cup (115 g) melted unsalted butter, 2 large eggs (room temperature), 1 teaspoon vanilla extract, and 3/4 cup (180 ml) whole milk. Mixing the wet ingredients separately makes it easier to incorporate into the dry.
5. Pour the wet mixture into the dry ingredients bowl. Stir gently with a wooden spoon or spatula until just combined. The batter should be thick but smooth, with no large flour pockets. Be careful not to overmix—overworking the batter can make the cake tough.
6. Fold in the blueberries: Add 1 1/2 cups (225 g) fresh blueberries and, if using, the zest of one lemon. Gently fold them in, so they don’t burst and turn the batter blue. This step adds those lovely fruity pockets throughout the cake.
7. Pour the batter evenly into your prepared pan. Smooth the top lightly with a spatula for an even bake.
8. Bake for 40-45 minutes. Start checking around 38 minutes by inserting a toothpick in the center. If it comes out clean or with a few moist crumbs (not wet batter), the cake is done. The top should be golden and spring back when pressed lightly.
9. Cool the cake in the pan for 10 minutes. Then carefully transfer to a wire rack to cool completely. This helps prevent sogginess on the bottom.

Pro tip: If your blueberries sink to the bottom, dusting them lightly with flour before folding in can help suspend them better. Also, don’t rush the cooling step—it lets the flavors settle, and the texture firms up just right.

Cooking Tips & Techniques

One-bowl cakes are all about simplicity, but a few tricks make a big difference:

• Room temperature eggs and milk: Cold ingredients can cause the batter to seize or mix unevenly. I usually take eggs out 30 minutes before baking.
• Gentle folding: When adding blueberries, fold with a light hand to keep them intact. Nobody wants a blue-streaked batter, right?
• Don’t overmix: Stir just until combined. Overmixing develops gluten, making the cake tougher than it should be.
• Even baking: Place the cake pan in the center of the oven. If your oven has hot spots, rotate halfway through baking for uniform color and doneness.
• Use fresh blueberries: They hold up better than frozen in this cake. If you must use frozen, toss them in flour and keep them mostly frozen until folding in.

Once, I tried rushing the mixing and ended up with a dense cake. Lesson learned—patience pays off. Also, keeping a kitchen timer handy ensures you don’t overbake, which dries out the crumb. Multitasking? Prep the dry ingredients while the oven heats—small efficiencies add up!

Variations & Adaptations

Want to switch things up? This Easy One-Bowl Loaded Blueberry Cake is a flexible canvas:

• Dietary swap: Use almond flour or a gluten-free blend for a gluten-free treat. Coconut yogurt or almond milk can replace dairy milk for a dairy-free version.
• Flavor twist: Add a teaspoon of cinnamon or cardamom to the batter for warm spice notes, or swap lemon zest for orange zest for a citrusy change.
• Seasonal swap: Try fresh raspberries, blackberries, or chopped peaches in place of blueberries for a different fruity punch.
• Texture play: Mix in a handful of chopped nuts like pecans or walnuts to add crunch.

Personally, I once added a streusel topping (brown sugar, butter, and oats) for an extra sweet crunch, and it was a hit at a summer potluck. Just sprinkle it on before baking.

Serving & Storage Suggestions

This cake is best served at room temperature or slightly warmed. I like to slice a piece, then pop it in the microwave for 10 seconds to bring out that fresh-baked feeling. It pairs beautifully with a cup of strong coffee or a light herbal tea.

For a simple dessert, a dollop of whipped cream or a scoop of vanilla ice cream makes it even more indulgent. If you’re serving brunch, fresh fruit on the side complements the blueberries nicely.

Store leftovers covered tightly at room temperature for up to 2 days, or refrigerate for 4-5 days. To freeze, wrap slices individually in plastic wrap and place in a freezer bag for up to 2 months. Thaw overnight in the fridge and warm gently before serving.

Over time, the flavors mellow and the cake becomes even more tender—a nice surprise if you can wait that long!

Nutritional Information & Benefits

This blueberry cake offers a satisfying treat without going overboard. Per serving (assuming 12 slices), it contains approximately:

• Calories: 220-250
• Fat: 10-12 grams (mostly from butter)
• Carbohydrates: 30 grams
• Protein: 3 grams

Blueberries bring antioxidants, vitamins C and K, and fiber, making this cake a bit more than just sugar and flour. Using real butter and whole milk adds richness but also provides vitamin A and calcium. If you swap in dairy-free milk or gluten-free flour, be mindful of nutritional changes.

For those watching allergens, the cake contains eggs, dairy, and gluten by default, but the swaps mentioned can accommodate various dietary needs.
