What You'll Need for these Cupcakes
Here is what you'll need for these cupcakes
- Bob's Red Mill Unbleached All-Purpose Flour. The flour provides structure and the right flour helps ensure a delicate crumb. It's my preferred flour for my baking.
- Granulated Sugar. The sugar obviously adds sweetness, but sugar also provides moisture to the cupcake and helps create the beautiful crumb on this cupcake.
- Unsalted Butter. Butter adds flavor, fat, and moisture to the cupcake
- Whole Milk. The milk adds moisture, flavor, and color to the cupcakes. Make sure you're using whole milk and not 2%, 1%, or skim milk.
- Whole Eggs. Whole eggs provide structure, flavor, color, and leavening to the cupcake. The proteins in the egg cause the other ingredients to bind together.
- Fresh Lemon Juice. The main flavor for these lemony cupcakes.
- Fresh Lemon Zest.
- Baking Powder. Provides the lift for these beautiful-looking cupcakes.
- Kosher Salt. The salt elevates all the other flavors.
Lemon Ermine Frosting
- Granulated Sugar. Makes the frosting sweet.
- Cornstarch. When combined with the flour thickens the slurry
- Bob's Red Mill Unbleached All-Purpose Flour. When combined with the cornstarch thickens the slurry.
- Whole Milk. The milk is used to make the thick roux-like paste.
- Lemon Juice. The lemon juice adds lots of citrus flavor.
- Kosher Salt. The salt adds a counterbalance to the sweetness of the frosting
- Unsalted Butter. Makes the final frosting creamy, smooth and silky. Use great-tasting butter to ensure the final frosting tastes good.
How to Make Lemon Cupcakes
The reverse creaming method is used to make these incredibly moist lemon cupcakes. In this method, the butter is mixed with the dry ingredients to coat the flour, which reduces the development of gluten. The final result is a tender and moist cupcake.
Place the sugar in a medium-size bowl and zest the lemons onto the sugar. Zesting the lemons ensures that the oils from the skin are captured into the recipe giving us a stronger lemon flavor.
If you zested the lemon onto a cutting board or piece of wax paper the lemon oil would be absorbed into the surface.
Place the sugar and all the other dry ingredients into the bowl of a stand mixer and mix on low speed with the paddle attachment to thoroughly combine the dry ingredients and evenly disperse the baking powder. (These cupcake cakes can also be made with a hand mixer).
Add the butter to the sugar and flour mixture and mix on medium speed to combine the butter with the dry ingredients. The mixture will be crumbly.
Add all the milk and mix on medium speed just until the milk is incorporated and the batter looks creamy. Next, add the eggs and beat the batter just until the eggs are incorporated.
Throughout the mixing process be careful not to overmix the batter.
Add the lemon juice and mix on medium to combine. Scrapes the sides and bottom of the bowl and mix in any batter that is not quite incorporated by hand.
Divide the cupcake batter evenly between the 12 cupcake cups, about 65 grams of batter for each cupcake. The cupcake liners should be about 2/3 full.
Bake the cupcakes for 20-22 minutes until they're done and the internal temperature is 202F degrees.
Cool the cupcakes in the cupcake pan for 10 minutes and then move them to a cooling rack. Let the cupcakes cool completely before frosting them.
The final cupcake has a moist crumb and these will be some of the best lemon cupcakes you've ever tasted.
How to Make the Lemon Ermine Frosting
Most homemade lemon cupcake recipes are topped with cream cheese frosting, but as soon as I tasted the final version of this recipe I knew I was going to make an ermine frosting. You will be amazed at how easy it is to make this delicious lemon frosting.
Ermine frosting is an easy eggless version of Swiss meringue buttercream. It's silky, buttery, light tasting, and less sweet than cream cheese frosting. And because it starts with a flour and sugar slurry it's easy to add a lot of natural flavor, like lemon juice without impacting the consistency.
The basic frosting recipe is made by combining milk, flour, cornstarch, and sugar and cooking it until it thickens. For the lemon version of this frosting, I added 2 tablespoons of lemon juice.
Once the mixture is thickened scrape into the bowl of a stand mixer and mix on medium-low speed until the mixture has cooled to room temperature.
Add the butter and mix on medium speed until the ingredients are combined. Increase the speed to medium-high until it's silky smooth and soft. The final result is a creamy lemon frosting.
Frost the cupcakes either with an offset spatula or use a piping bag with a Wilton 1M tip to frost the cupcakes with a beautiful swirl pattern.
How to Store the Cupcakes
- Store the unfrosted cupcakes can at room temperature in an airtight container for a day
- Store the frosted cupcakes at room temperature for one day and in the refrigerator for three days in an airtight container.
Why You'll Love These Lemon Cupcakes
Lemon is one of my favorite flavors and if you love lemon desserts this lemon cupcake recipe is destined to become one of your favorite cupcake recipes. The cupcakes have a fluffy, moist crumb with plenty of lemon zest and lemon juice to make sure you don't miss the lemon. The lemon ermine frosting is silky, creamy, and slightly tart with plenty of lemon flavor. Each bite is perfect.
Pro Tips for Making This Recipe
- Use a scale to weigh your flour and sugar for the best results. Too much flour will result in a dry cupcake. Too little flour will result in a sunken cupcake because there is not enough flour to provide structure for the liquid and the fats in the recipe.
- The butter, eggs, and milk should all be a room temperature, which is typically between 65-68F. Room temperature ingredients blend more easily together. In addition, eggs straight from the refrigerator will result in a dense cake.
- Do not use bottled lemon juice. It has a different flavor than freshly squeezed lemon juice.
Cupcake Recipe - Frequently Asked Questions
For these cupcakes, butter is definitely better. Butter not only adds a lot of flavor but produces a cupcake that is soft and tender.
No, don't use bottled lemon juice, it has a slightly off taste and you don't get the same tart lemon flavor in the cupcake and frosting.
If your cupcakes are dry then you added too much flour to the recipe. Use a scale to weigh the flour to ensure you have the right amount.
