• This delightful recipe will have you baking in no time!

For the Cupcakes

Granulated Sugar – Adds sweetness; can substitute with cane sugar or coconut sugar for a different flavor.
Fresh Lemon Zest – Provides citrus aroma and flavor; use the zest of 1 large lemon for the best results.
Full-fat Sour Cream – Adds moisture and richness; substitute with dairy-free yogurt for a dairy-free option.
Water – Hydrates the batter; replace with milk or lemon juice for added flavor.
Vegetable/Canola Oil – Adds moisture; melted coconut oil can be used for a tropical twist.
Large Egg – Provides structure and moisture; a flax egg or unsweetened applesauce works as a vegan substitute.
Lemon Extract – Enhances citrus flavor; in a pinch, vanilla extract can be used instead.
Vanilla Extract – Adds warmth and sweetness; can be omitted if you want to highlight the lemon flavor.
Cake Flour – Gives a tender crumb; for a gluten-free option, swap with gluten-free cake flour blend.
Poppy Seeds – Introduce a nutty taste and a delightful crunch; omit if making lemon-only cupcakes.
Baking Powder – Our trusty leavening agent; make sure it’s fresh for best rise.
Fine Salt – Balances sweetness; kosher salt can be used as an alternative.

For the Lemon Cream Cheese Buttercream

Unsalted Butter – Adds richness; vegan butter can be used for a dairy-free version.
Cream Cheese – Offers tang and creaminess; dairy-free cream cheese is great for a vegan option.
Fresh Lemon Zest – Intensifies flavor; if unavailable, use a bit more powdered sugar.
Powdered Sugar – Sweetens and thickens the frosting; powdered coconut sugar is a healthier swap.
Lemon Juice – Balances the frosting’s sweetness; fresh juice will enhance the flavor beautifully.

Step‑by‑Step Instructions for Lemon Poppy Seed Cupcakes

Step 1: Preheat the Oven
Start by preheating your oven to 350°F (175°C), allowing it to reach the perfect baking temperature. While the oven heats, prepare a muffin pan with 12 cupcake liners to ensure your Lemon Poppy Seed Cupcakes have a beautiful presentation and easy removal once baked.

Step 2: Prepare Lemon Sugar
In a mixing bowl, combine granulated sugar with the zest of one large lemon. Using your fingertips, massage the lemon zest into the sugar for about a minute. This step releases aromatic oils, elevating the flavor profile of your Lemon Poppy Seed Cupcakes and creating a fragrant base for your batter.

Step 3: Mix Wet Ingredients
In a separate bowl, whisk together full-fat sour cream, water, vegetable oil, large egg, lemon extract, and vanilla extract until fully combined. This mixture should be smooth and creamy, creating a delightful balance of flavors that will give your cupcakes a moist texture as they bake.

Step 4: Combine Dry Ingredients
In another bowl, whisk together cake flour, the prepared lemon sugar, poppy seeds, baking powder, and fine salt. Ensure that you blend these dry ingredients thoroughly to eliminate any lumps, which will help your Lemon Poppy Seed Cupcakes rise evenly and achieve a tender crumb.

Step 5: Combine Mixtures
Gradually add the dry ingredients to the wet ingredients, gently mixing until just combined. Take care to avoid overmixing, as this can lead to dense cupcakes. You want a slightly thick batter with a few small lumps, ensuring your Lemon Poppy Seed Cupcakes remain light and fluffy when baked.

Step 6: Fill Cupcake Liners
Using a cookie scoop or spoon, fill each cupcake liner about three-quarters full with the batter. This will allow enough room for the cupcakes to rise without overflowing. Slide the pan into the preheated oven and bake for 18-21 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs.

Step 7: Cool the Cupcakes
Once baked, remove the pan from the oven and let the cupcakes cool in the pan for about 10 minutes. Afterward, carefully transfer them to a wire cooling rack, allowing them to cool completely. This step is essential, as it prevents the cupcakes from becoming soggy in the liners.

Step 8: Make the Frosting
In a large mixing bowl, beat together unsalted butter and cream cheese until smooth and creamy. Gradually add in fresh lemon zest, vanilla extract, salt, and powdered sugar, mixing until well incorporated. You’re aiming for a velvety and spreadable texture perfect for topping your Lemon Poppy Seed Cupcakes.

Step 9: Adjust Consistency
Once everything is mixed, taste your frosting and adjust the consistency as needed. If it’s too thick, add a splash of fresh lemon juice; if it’s too thin, sprinkle in more powdered sugar. This final adjustment ensures your frosting is both flavorful and the right texture for smooth application.

Step 10: Frost Cupcakes
If desired, hollow out the center of each cupcake and fill with lemon curd. Top with a generous dollop of the creamy lemon frosting, swirling it into peaks for a delightful finish. For an extra touch, garnish each cupcake with a heart made from lemon peel, adding a pop of color and charm to your Lemon Poppy Seed Cupcakes!
