Tips for Making Lemon Poppyseed Cupcakes
- Ensure that your eggs and sour cream are at room temperature. This helps achieve a smoother and more even batter.
- When zesting lemons, use a fine grater or a micro plane for the best results. Avoid grating the white pith, which can be bitter.
- When combining the wet and dry ingredients, mix just until they’re incorporated. Overmixing can lead to dense cupcakes.
- Make sure the cupcakes are completely cooled before frosting. Warm cupcakes can cause the frosting to melt.
How to Make Lemon Poppyseed Cupcakes
Step One
Preheat the oven to 320° F. Fill two cupcake trays with 15 liners total.
Sift together the dry ingredients, except the sugar and set it aside.

Step Two
In a mixing bowl, combine the vegetable oil with the sugar and lemon zest. Beat until fluffy, about 1 minute.

Step Three
Add the eggs, one at a time, until fully incorporated.

Step Four
With the mixer on low speed, slowly add the dry ingredients to the bowl and mix, scraping down the sides, until fully incorporated.
Add the sour cream, vanilla extract and lemon juice. Mix just until combined. Do not overmix.

Step Five
Divide the batter among the cupcake liners, filling each about 2/3 full. Bake for 20-22 minutes, until a toothpick inserted comes out clean.

Step Six
Remove the cupcakes from the oven. Cool for 5 minutes on a wire rack, then remove the cupcakes from the tray and cool completely.

Step Seven
To make the buttercream frosting, combine the butter and lemon juice in a mixing bowl. Beat until fluffy, about 4 minutes.
Add the powdered sugar, a little at a time, until fully incorporated. Then add the vanilla extract and lemon juice until fully incorporated. Scrape down the sides of the bowl and mix the frosting for 1 minute.
Transfer the frosting to a piping bag with a 1M tip. Frost the cupcakes once they are cooled. Decorate with the poppy seeds and lemon slices.

How to Store
Room Temperature: If you plan to enjoy the cupcakes within 1-2 days, you can store them at room temperature in an airtight container. Keep them away from direct sunlight and heat.
Fridge: For longer storage, place the cupcakes in an airtight container and refrigerate them. This helps preserve freshness and prevents the frosting from melting. Remember to let them come to room temperature before serving for the best taste and texture.
Freezer: To freeze unfrosted cupcakes, wrap each one individually in plastic wrap and then place them in an airtight container or a zip-top freezer bag. They can be stored in the freezer for up to 3 months.

Frequently Asked Questions
Can I use a different type of flour, like whole wheat flour, in this recipe?
Yes, you can substitute all-purpose flour with whole wheat flour, but keep in mind that the cupcakes might have a slightly denser texture and a nuttier flavor.
How do I prevent the cupcakes from sticking to the paper liners?
To prevent sticking, consider using high-quality non-stick cupcake liners. You can also lightly spray the liners with non-stick cooking spray. Let the cupcakes cool in the muffin tin for a few minutes before transferring them to a wire rack; this can also help reduce sticking.
What can I use if I don’t have sour cream?
If you don’t have sour cream, Greek yogurt makes an excellent substitute in this recipe. It provides a similar tangy flavor and moisture to the cupcakes.
Can I make mini cupcakes with this recipe?
Yes, you can make mini cupcakes using this recipe. Just reduce the baking time; start checking for doneness around 10-12 minutes. Mini cupcakes will bake faster than standard-sized ones.
