Ingredient Notes

Here are some notes on the ingredients. For a full list of ingredients, check out the recipe card below.

  • Unsalted butter- The butter for the batter needs to be room temperature before baking (pull this out 2 hours before baking). The butter for the frosting needs to be slightly cold. This gives it the perfect texture for piping.
  • Oil- You can use canola oil or vegetable oil.
  • Lemon zest- You will need 2 lemons. Use a lemon zester.
  • Fresh Lemon juice- The recipe is best with freshly squeezed lemon juice.
  • Sour cream- Use full fat sour cream. Pull this out 2 hours before baking.
  • Eggs- Pull the large eggs out 2 hours before baking.
  • Buttermilk- Use full fat or reduced fat buttermilk. Pull this out 2 hours before baking.
  • Cream cheese- Use full fat cream cheese. Pull this out 2 hours before baking.
  • Powdered sugar- Sift the powdered sugar to prevent a gritty frosting.

Substitutions

  • Lemon juice- You can use bottle lemon juice instead.
  • Sour cream- You can use full fat plain yogurt or greek yogurt.
  • Buttermilk- Use 1/2 cup whole milk and add in a 1/2 Tablespoon of lemon juice. Let this sit for 10 minutes before using.
  • Poppy seeds- You can not use these.
  • Cream cheese- You can do 1 cup of butter instead of cream cheese.

STEP 3: Add in the eggs. Mix these in on low speed. Then, turn up to high speed and beat for 2 minutes.

Decorating The Cupcakes

Use a piping bag to pipe the frosting on top of these cupcakes. If the frosting is too “relaxed” or runny, place in the freezer for 5-8 minutes until it firms slightly.

I used a Wilton tip 1M to decorate these. I also topped them with a little lemon triangle.

Expert Baking Tips

  • Flour- Make sure flour is spooned and leveled. If you stick your measuring cup directly in the flour it will compact it. This can dry out the cupcake.
  • The wet ingredients need to be beaten on high speed for a total of 5 minutes. This helps to give it more air, and it is a more fluffy texture.
  • If you don’t like the taste for fresh poppy seeds, you can skip adding it to the frosting.
  • The frosting should be very creamy and be beaten on high to get it fluffy.
