Ingredients

¾ cup all-purpose flour, plus 1 to 2 tablespoons more if needed
¼ cup granulated sugar
¼ cup light brown sugar, packed
½ teaspoon salt, or to taste

6 tablespoons unsalted butter, melted
1 cup all-purpose flour
¾ cup granulated sugar
2 teaspoons baking powder

½ teaspoon salt, or to taste
1 large egg
½ cup buttermilk
⅓ cup sour cream, lite is okay (plain Greek yogurt may be substituted)

¼ cup canola or vegetable oil
2 teaspoons vanilla extract
1 cup fresh blueberries, plus ¼ cup more for sprinkling on top if desired

Instructions

Begin by setting your oven to 350°F (175°C) and lining an 8-by-8-inch square baking pan with aluminum foil. Lightly coat the foil with nonstick cooking spray, ensuring every corner is covered to make cake removal effortless. Set the prepared pan aside for later.
Prepare the streusel topping by combining ¾ cup all-purpose flour, both the granulated and light brown sugars, and ½ teaspoon of salt in a medium-sized mixing bowl. Use a fork to thoroughly combine these ingredients, ensuring an even mix that will help the topping bake evenly.
Slowly pour the melted unsalted butter over the dry streusel mixture. Gently mix and fluff the mixture with a fork rather than stirring vigorously. The goal is to create small, marble-sized pebbles and crumbs. If you notice that the mixture remains too moist and isn't forming the desired crumbly texture, add an additional 1 to 2 tablespoons of flour and continue to fluff until you achieve the perfect streusel consistency. Set aside.
For the cake base, whisk together 1 cup all-purpose flour, ¾ cup granulated sugar, 2 teaspoons baking powder, and ½ teaspoon salt in a large mixing bowl. Take a moment to break up any lumps and ensure uniform distribution of the leavening and salt throughout the flour.

In a separate smaller bowl, whisk together the egg, buttermilk, sour cream (or Greek yogurt if you prefer), canola or vegetable oil, and vanilla extract until the mixture is smooth and homogenous. This will help your cake bake up moist and flavorful.
Pour the wet ingredients into the bowl with the dry ingredients. Use a rubber spatula or a large spoon to gently fold the mixtures together. The batter should look slightly lumpy; avoid overmixing, as this can make the cake dense rather than soft. Overmixed batter can lose its tender crumb once baked.
Fold in 1 cup of fresh blueberries, ensuring they are evenly distributed throughout the batter. If your blueberries are particularly large or you wish to keep them from sinking to the bottom, lightly toss them in a tablespoon of flour before adding to the batter-this tip helps suspend the berries throughout the cake.
Transfer the batter into your prepared baking pan, gently spreading it into the corners for an even layer. Sprinkle the streusel topping evenly across the surface of the batter, ensuring every area gets a generous amount of those buttery, crumbly bits. If you wish, add an extra ¼ cup of blueberries across the top for an attractive and fruity finish.

Place the pan on the center rack of your preheated oven. Bake for 45 to 50 minutes, starting to check doneness at the 40-minute mark. Insert a toothpick into the center of the cake; it should come out clean or with a few moist crumbs attached but no raw batter. Baking times can vary due to differences in ovens, pans, and fruit moisture, so adjust as necessary.
Once baked, remove the pan from the oven and place it on a wire rack to cool. Allow the cake to come to room temperature before slicing to ensure clean cuts and the best texture. Serve straight from the pan or transfer slices to a serving platter for a beautiful presentation.

Nutritional Information

Blueberry Streusel Coffee Cake is rich and satisfying, making it a delightful treat best enjoyed in moderation. An average serving (1/9 of the cake) delivers approximately 300-350 calories, comprised principally of carbohydrates and healthy fats.

The blueberries contribute dietary fiber, vitamin C, and antioxidants, supporting immune health while adding natural sweetness to the cake. The inclusion of buttermilk and sour cream provides a boost of calcium and a bit of protein, supporting bone health and satiety.

Still, as with most coffee cakes, this recipe contains added sugars and butter, both in the cake and the streusel topping, making it a dessert or special-occasion breakfast rather than an everyday snack for those watching their sugar or calorie intake.

Using unsaturated oil (canola or vegetable) helps balance the saturated fat from butter, while the measured use of salt enhances flavor without excessive sodium. For those seeking a little extra nutrition, serving with fresh fruit or a dollop of plain yogurt can further increase the meal's health value.

This Blueberry Streusel Coffee Cake provides a comforting, sweet treat with a modest dose of vitamins and minerals, especially when enjoyed as part of a balanced diet.

Wine and Beverage Pairings

Blueberry Streusel Coffee Cake is perfectly complemented by a hot cup of freshly brewed coffee, emphasizing the classic pairing that inspired its name. Opt for medium or light roast coffees with fruity notes to enhance the natural blueberry flavor in the cake.

For those who prefer tea, an Earl Grey or English Breakfast blend provides a robust counterpoint to the sweet, crumbly cake.

For a more luxurious brunch, consider pairing slices with a glass of chilled Prosecco or Moscato d'Asti-the gentle bubbles and subtle sweetness balance the richness of the streusel and cake beautifully. Non-alcoholic options like chilled lemonade or a homemade blueberry iced tea also make delightful, refreshing accompaniments.

Cooking Tips and Variations

To achieve the best results with this Blueberry Streusel Coffee Cake recipe, ensure your ingredients are at room temperature before mixing-this promotes an even, tender crumb.

If fresh blueberries aren't in season, you may substitute with frozen ones, but do not thaw them to prevent extra moisture from seeping into the batter. For an enhanced flavor profile, try adding a teaspoon of finely grated lemon zest to the cake batter for a subtle citrus brightness.

If you desire extra crunch, consider adding a handful of chopped walnuts or pecans to the streusel topping. Overmixing the batter is the most common mistake; mixing just until the dry and wet ingredients are combined ensures your cake will remain soft.

You can also vary the berries by experimenting with raspberries, blackberries, or a combination for an assorted berry coffee cake. If you prefer a lower-sugar version, reduce the brown sugar in the topping and replace half of the granulated sugar in the cake with a sugar alternative suitable for baking.

When storing leftover coffee cake, wrap it tightly or keep it in an airtight container to maintain freshness for up to three days, or freeze individual slices for up to one month. Reheat gently before serving to revive the moist texture and aroma.

Serving Suggestions

This Blueberry Streusel Coffee Cake shines as a breakfast centerpiece or a brunch favorite. Slice into generous squares and serve slightly warm for the ultimate comforting experience; warming the cake just before serving will reawaken the aroma and texture of the crumbly streusel topping.

Arrange slices on a decorative platter for holidays or special gatherings, and consider garnishing with a dusting of powdered sugar or a scattering of fresh blueberries for extra appeal.

For elegant presentations, pair a slice of cake with a swirl of whipped cream, a scoop of vanilla ice cream, or a dollop of lightly sweetened Greek yogurt. At casual gatherings or potlucks, this cake travels well and can be enjoyed at room temperature.

If serving for breakfast or brunch, accompany the coffee cake with a fresh fruit salad, yogurt parfait, or scrambled eggs for a balanced spread. For dessert, the cake's flavors pair well with a drizzle of lemon glaze or a scoop of berry sorbet.

Versatile and charming, this coffee cake ensures every meal or celebration feels a bit more special and inviting.

Health Benefits

While Blueberry Streusel Coffee Cake is an indulgent treat, it features a few beneficial components. Blueberries are a nutritional powerhouse, providing antioxidants such as anthocyanins that help reduce oxidative stress and support a healthy immune system.

The use of buttermilk and sour cream (or Greek yogurt) adds calcium and probiotics, enhancing bone health and digestive well-being. The healthy fats from canola or vegetable oil contribute to a more balanced fat profile compared to recipes made solely with butter.

However, since this cake contains added sugars and refined flour, those monitoring blood sugar levels or adhering to low-sugar diets should enjoy the cake in moderation.

For a slightly healthier version, you can experiment by reducing the sugar in the streusel or cake batter, using whole-wheat pastry flour for partial flour replacement, or increasing the proportion of fresh berries.

Overall, this recipe offers a delightful way to integrate the benefits of blueberries and cultured dairy into a classic baked good, making it both nourishing and satisfying when consumed as part of a varied diet.
