Cook Sour Cream Vanilla Cupcakes Like This

Step 1: Preheat Your Oven
Preheat your oven to 350°F (175°C). This ensures your cupcakes bake evenly and rise beautifully.
Step 2: Prepare the Cupcake Pan
Line a cupcake pan with cupcake liners. This makes for easy removal and adds a pop of color to your presentation.
Step 3: Cream the Butter and Sugar
In a large mixing bowl, beat the 3/4 cup of softened unsalted butter and 1 1/2 cups of granulated sugar together until light and fluffy. This usually takes about 3-5 minutes with an electric mixer.
Step 4: Add the Eggs
Add the 3 large eggs, one at a time, mixing well after each addition. This helps to incorporate air into the batter, which contributes to a lighter cupcake.
Step 5: Incorporate the Vanilla
Stir in 1 1/2 teaspoons of vanilla extract and 1/4 teaspoon of dried vanilla beans. This step enhances the vanilla flavor throughout the cupcakes.
Step 6: Mix in the Sour Cream and Milk
Add 1 cup of sour cream and 1/4 cup of milk to the mixture. Beat until well combined. The sour cream adds moisture and a slight tang that balances the sweetness.
Step 7: Combine the Dry Ingredients
In a separate bowl, whisk together 2 1/2 cups of all-purpose flour, 2 teaspoons of baking powder, 1/2 teaspoon of baking soda, and 1/2 teaspoon of salt. This ensures that the leavening agents are evenly distributed.
Step 8: Combine Wet and Dry Ingredients
Gradually add the dry ingredients to the wet mixture, mixing just until combined. Be careful not to overmix, as this can lead to dense cupcakes.
Step 9: Fill the Cupcake Liners
Spoon the batter into the prepared cupcake liners, filling each about two-thirds full. This allows room for the cupcakes to rise without overflowing.
Step 10: Bake
Place the cupcake pan in the preheated oven and bake for 18-20 minutes, or until a toothpick inserted into the center comes out clean.
Step 11: Cool the Cupcakes
Once baked, remove the pan from the oven and let the cupcakes cool in the pan for about 5 minutes. Then, transfer them to a cooling rack to cool completely.
Step 12: Prepare the Frosting
In a medium bowl, beat 1/2 cup of softened butter until creamy. Gradually add 1 lb of powdered sugar, mixing until smooth. Add 1-2 tablespoons of milk and 1 teaspoon of vanilla, mixing until you reach your desired consistency.
Step 13: Frost the Cupcakes
Once the cupcakes are completely cool, frost them with your prepared frosting. You can use a piping bag for a decorative touch or simply spread it on with a knife.
Season-by-Season Upgrades

- Spring: Top with fresh berries or a lemon glaze for a refreshing twist.
- Summer: Add a hint of coconut extract and sprinkle with toasted coconut flakes.
- Fall: Incorporate a dash of cinnamon or nutmeg for a warm flavor profile.
- Winter: Try adding peppermint extract for a holiday-inspired treat.
Notes from the Test Kitchen
For the best results, ensure all your ingredients are at room temperature before starting. This helps to create a smooth batter and ensures even baking. If you prefer a lighter cupcake, you can substitute half of the all-purpose flour with cake flour.
Storage Pro Tips
To store your Sour Cream Vanilla Cupcakes, place them in an airtight container at room temperature for up to 3 days. If you want to keep them longer, refrigerate for up to a week or freeze them for up to 3 months. Just make sure to frost them after thawing if you choose to freeze!
Troubleshooting Q&A
What should I do if my cupcakes are dense?
If your cupcakes turn out dense, it may be due to overmixing the batter or not measuring the flour correctly. Make sure to mix just until the ingredients are combined and spoon the flour into the measuring cup without packing it down.
How can I achieve a more pronounced vanilla flavor?
For a more intense vanilla flavor, consider using vanilla bean paste instead of extract. You can also use the seeds from a vanilla pod for an even richer taste.
My frosting is too runny. What can I do?
If your frosting is too runny, gradually add more powdered sugar until it reaches your desired consistency. If it becomes too thick, add a little more milk, one teaspoon at a time.
Can I make these cupcakes gluten-free?
Yes! You can substitute the all-purpose flour with a gluten-free blend. Just ensure the blend you choose is suitable for baking, and follow the package instructions for best results.
In Closing
