How to make Lemon Cupcakes?
Prepare the wet ingredients. In a liquid measuring cup, add and measure melted butter, vegetable oil, milk, lemon zest and pure vanilla extract. Mix until blended. This will let the lemon zest infuse and will not dry out while preparing other ingredients.
In a medium-sized bowl, whisk the egg yolks, granulated sugar and lemon juice until egg yolks are pale in colour and sugar is almost dissolved.
Weigh, measure and sift the dry ingredients. Weigh the cake flour or spoon in a measuring cup and level it off with a spatula. Sift in a strainer over parchment paper with the baking powder and salt.
Mix the dry and wet ingredients. Add in the egg yolk mixture in 4 additions alternately with the wet ingredients. Mix until blended.
For the meringue. Whisk the egg whites gradually add sugar and whisk until medium-stiff peaks.
Mixing the cake batter and meringue. Add the meringue to the cake batter in four additions. Cut and fold and avoid over-mixing.
Scoop the cake batter to portion evenly. Line the 12-muffin pan with a muffin paper liner. Scoop and portion evenly about 3/4 full using an ice cream scoop with the trigger.
Bake the cupcakes. Bake in preheated oven to 375°F for about 12 to 15 minutes or until the toothpick inserted comes out clean. Let it cool in a pan for 10 minutes.
For the lemon syrup. Mix the sugar and lemon juice in a small bowl and microwave for about 15 seconds or until the sugar is dissolved. While the cupcakes are still hot in the muffin pan, brush the top of each cupcake with lemon syrup. Transfer to a cooling rack to cool completely.
How to make the Lemon Buttercream Frosting? Melt the semi-sweet white chocolate chips in a small bowl over a bowl of hot water. Set aside and let it cool but not set. Meanwhile, whisk the softened butter in a medium-sized bowl until light and fluffy. Scrape the bowl. Add 1/2 cup of sifted icing sugar, whisk until blended then add the lemon zest.
Add the remaining sifted icing sugar 1/2 cup at a time alternately with the wet ingredients. Scrape the bowl in between each addition.
Finally, add the cooled melted white chocolate, this will stabilize the buttercream without adding lots of icing sugar. Whisk until light and fluffy.
Adjust the amount of sugar to your preferred sweetness and consistency.
Colour the buttercream frosting (optional). In a small bowl, add ⅓ of the buttercream frosting and then add a few drops of yellow icing colour. Mix until well blended.
