So, let's get baking!

Ingredients:
- For the Lemon Blueberry Loaf:
- 2 cups (250g) all-purpose flour
- 2 teaspoons baking powder
- 1/2 teaspoon baking soda
- 1/4 teaspoon salt
- 1 cup (2 sticks or 226g) unsalted butter, softened
- 1 1/2 cups (300g) granulated sugar
- 2 large eggs
- 1 teaspoon vanilla extract
- 1/2 cup (120ml) sour cream
- 1/4 cup (60ml) milk
- 2 tablespoons lemon zest, finely grated
- 2 tablespoons lemon juice, freshly squeezed
- 1 1/2 cups (approximately 180g) fresh blueberries, rinsed and dried thoroughly
- For the Lemon Glaze:
- 1 cup (120g) powdered sugar
- 2-3 tablespoons lemon juice, freshly squeezed
Preparing the Batter:
- Preheat and Prepare: First things first, let's get our oven ready. Preheat it to 350°F (175°C). While the oven is heating up, grease and flour a 9x5 inch loaf pan. I like to use baking spray with flour already in it for extra insurance against sticking, but good old butter and flour work just as well. Make sure you get into all the corners!
- Dry Ingredients: In a medium-sized bowl, whisk together the flour, baking powder, baking soda, and salt. Whisking is important here to ensure everything is evenly distributed. This helps the cake rise properly and have a nice, even texture. Set this bowl aside for now.
- Cream Butter and Sugar: In a large bowl (or the bowl of your stand mixer), cream together the softened butter and granulated sugar until light and fluffy. This usually takes about 3-5 minutes on medium speed. Don't rush this step! The creaming process incorporates air into the butter and sugar, which is crucial for a tender cake. You should see a noticeable change in color and texture.
- Add Eggs and Vanilla: Beat in the eggs one at a time, making sure each egg is fully incorporated before adding the next. Then, stir in the vanilla extract. I always use pure vanilla extract for the best flavor, but imitation vanilla will work in a pinch.
- Combine Wet and Dry Ingredients: Gradually add the dry ingredients to the wet ingredients, alternating with the sour cream and milk. Begin and end with the dry ingredients. So, add about a third of the dry ingredients, then half of the sour cream and milk mixture, then another third of the dry ingredients, then the remaining sour cream and milk, and finally the last of the dry ingredients. Mix until just combined. Be careful not to overmix! Overmixing develops the gluten in the flour, which can result in a tough cake.
- Add Lemon Zest and Juice: Stir in the lemon zest and lemon juice. The lemon zest adds a wonderful aromatic flavor, while the lemon juice provides a touch of tanginess.
- Fold in Blueberries: Gently fold in the blueberries. I like to toss the blueberries with a tablespoon of flour before adding them to the batter. This helps prevent them from sinking to the bottom of the cake during baking. Be gentle when folding, as you don't want to crush the blueberries and turn the batter blue.
Baking Process:
- Pour into Pan: Pour the batter into the prepared loaf pan and spread it evenly.
- Bake: Bake for 50-60 minutes, or until a wooden skewer inserted into the center comes out clean or with just a few moist crumbs attached. The baking time may vary depending on your oven, so keep an eye on it.
- Cool: Let the loaf cool in the pan for 10-15 minutes before inverting it onto a wire rack to cool completely. Cooling it in the pan first prevents it from breaking apart.
Preparing the Lemon Glaze:
- Whisk Together: In a small bowl, whisk together the powdered sugar and lemon juice until smooth. Start with 2 tablespoons of lemon juice and add more, one teaspoon at a time, until you reach your desired consistency. The glaze should be thick enough to coat the cake but thin enough to drizzle easily.
- Glaze the Cake: Once the cake is completely cool, drizzle the lemon glaze over the top. You can let the glaze drip down the sides for a more rustic look, or you can spread it evenly over the top.
- Let Set: Allow the glaze to set for about 15-20 minutes before slicing and serving. This gives the glaze time to harden slightly.
Tips for Success:
- Room Temperature Ingredients: Using room temperature ingredients, especially the butter and eggs, is crucial for a smooth and even batter. Room temperature ingredients emulsify better, resulting in a more tender and moist cake.
- Don't Overmix: Overmixing the batter develops the gluten in the flour, which can lead to a tough cake. Mix until just combined.
- Check for Doneness: Use a wooden skewer or toothpick to check for doneness. Insert it into the center of the cake. If it comes out clean or with just a few moist crumbs attached, the cake is done.
- Cool Completely: Make sure the cake is completely cool before glazing. If the cake is still warm, the glaze will melt and run off.
- Fresh Blueberries: While you can use frozen blueberries, fresh blueberries are preferred for their texture and flavor. If using frozen blueberries, do not thaw them before adding them to the batter. Toss them with flour to prevent them from bleeding into the batter.
- Lemon Flavor: For a more intense lemon flavor, you can add a teaspoon of lemon extract to the batter.
- Storage: Store the loaf cake in an airtight container at room temperature for up to 3 days or in the refrigerator for up to a week.
Variations:
- Poppy Seed: Add 2 tablespoons of poppy seeds to the batter for a nutty flavor and texture.
- Orange Zest: Substitute orange zest for lemon zest for a different citrus flavor.
- Nuts: Add 1/2 cup of chopped nuts, such as walnuts or pecans, to the batter for added crunch.
- Chocolate Chips: Add 1/2 cup of white chocolate chips to the batter for a touch of sweetness.
- Glaze Variations: Experiment with different glaze flavors, such as a blueberry glaze or a vanilla glaze.
Troubleshooting:
- Cake is dry: Overbaking is the most common cause of a dry cake. Make sure to check for doneness frequently and remove the cake from the oven as soon as it's done. Also, make sure you're using the correct amount of ingredients and that your oven temperature is accurate.
- Cake is sinking in the middle: This can be caused by several factors, including using too much leavening agent (baking powder or baking soda), overmixing the batter, or opening the oven door too frequently during baking.
- Blueberries are sinking to the bottom: Tossing the blueberries with flour before adding them to the batter helps prevent them from sinking. Also, make sure the batter is thick enough to support the blueberries.
- Glaze is too thick: Add more lemon juice, one teaspoon at a time, until you reach your desired consistency.
- Glaze is too thin: Add more powdered sugar, one tablespoon at a time, until you reach your desired consistency.
