Ingredients You’ll Need for the Cupcakes

Lemon Cake Mix – The base of the recipe! (Yellow cake mix works in a pinch.) The cake mix gives a fluffy crumb while keeping the recipe quick and foolproof.

Instant Lemon Pudding Mix – Boosts the lemon flavor and adds extra moisture, helping the cupcakes stay soft and tender instead of dry.

Oil – Keeps the cupcakes moist and gives them a tender texture.

Eggs – Binds the ingredients together.

Poppy Seeds – Adds classic lemon-poppy texture and a subtle crunch without weighing down the batter.

Hot Water – Activates the pudding mix and helps create a smooth batter.

And the Lemon Cream Cheese Frosting

Butter (Softened) – Provides richness and helps the frosting hold its shape while staying smooth and creamy.

Cream Cheese (Softened) – Adds a tangy flavor that balances the sweetness and pairs perfectly with bright lemon cupcakes.

Powdered Sugar – Sweetens the frosting and thickens it to a smooth, spreadable consistency.

Lemon Juice – Brings fresh, bright citrus flavor that cuts through the richness of the butter and cream cheese.

Vanilla – Rounds out the lemon flavor and adds warmth, keeping the frosting from tasting too sharp.

Lemon Zest – Optional, but I recommend it for a pretty looking final touch!

How to Make Lemon Poppy Seed Cupcakes with Cake Mix

NOTE: You can substitute the lemon cake mix with yellow cake mix.

Preheat oven to 350 degrees. Line a muffin pan with liners.

Beat together 1 box lemon cake mix, 1 (3.4 oz) box instant lemon pudding mix, 1/2 cup oil, 4 eggs, 1/4 cup poppy seeds, and 1 cup hot water until well combined.

Fill muffin liners until almost full.

Bake for 15-20 minutes or until a toothpick inserted in the center comes out clean. Moist crumbs are okay, you don’t want to over bake the muffins.

In a large bowl, beat together 1/2 cup softened butter, 1 (8 oz) softened cream cheese, 3 1/2 cups powdered sugar, 2 tbsp lemon juice, and 1 tsp vanilla until smooth and creamy.

Pipe, or spread, onto cooled cupcakes.

Optional: Top with lemon zest.

Fill Cupcake Liners Until Almost Full – Cake mix batters don’t rise as much as scratch batters, so filling them higher gives nicely domed cupcakes.

Watch Baking Time Closely – Bake just until a toothpick come out with moist crumbs. Overbaking will produce dry cupcakes.

Lemon Juice Substitute – You can use store bought in place of fresh.

Top with Lemon Zest – I love to top with fresh lemon zest to make them look pretty!
