Ingredients
Servings
12
- 1 ¾ cups gluten-free all-purpose flour blend (ensure it contains xanthan gum)
- 1 teaspoon baking powder
- ½ teaspoon baking soda
- ¼ teaspoon salt
- 2 tablespoons poppy seeds
- Zest of 2 medium lemons
- 3 large eggs, at room temperature
- ¾ cup granulated sugar
- ½ cup coconut oil, melted and slightly cooled
- ½ cup plain dairy-free yogurt (such as coconut or almond yogurt)
- 2 tablespoons fresh lemon juice
- 1 teaspoon pure vanilla extract
- 1 cup dairy-free butter substitute, softened (e.g., vegan margarine or coconut oil-based butter)
- 3 to 4 cups powdered sugar, sifted
- 2 tablespoons fresh lemon juice
- 1 teaspoon lemon zest
- 1 teaspoon pure vanilla extract
- Pinch of salt
Instructions
-
Preheat your oven to 350 degrees F. Line a 12-cup muffin tin with cupcake liners.
-
In a medium bowl, whisk together the gluten-free flour, baking powder, baking soda, salt, and poppy seeds. Stir in the lemon zest evenly.
-
In a large mixing bowl, beat the eggs with sugar until pale and fluffy, about 2-3 minutes. Add the melted coconut oil, dairy-free yogurt, lemon juice, and vanilla extract. Mix until combined.
-
Gradually add the dry ingredients to the wet ingredients. Fold gently with a spatula until just combined. Avoid overmixing to keep cupcakes tender.
-
Divide the batter evenly among the 12 cupcake liners, filling each about 2/3 full.
-
Bake for 16-18 minutes, or until a toothpick inserted in the center comes out clean.
-
Remove cupcakes from the oven and let them cool in the pan for 5 minutes, then transfer to a wire rack to cool completely before frosting.
-
For the frosting: In a large bowl, beat the dairy-free butter substitute until smooth and creamy, about 2 minutes.
-
Gradually add 3 cups of powdered sugar, mixing well after each addition.
-
Add the lemon juice, lemon zest, vanilla extract, and a pinch of salt; beat until smooth and fluffy. If frosting is too thick, add a teaspoon of plant milk or water to loosen. If too thin, add more powdered sugar as needed.
-
Once cupcakes are completely cooled, frost them generously using a piping bag or spatula.
-
Optional: Garnish with a light sprinkle of additional poppy seeds or a thin slice of lemon zest for decoration.
-
Store cupcakes in an airtight container in the refrigerator for up to 5 days or freeze unfrosted cupcakes in a freezer-safe container for up to 3 months. Thaw at room temperature before frosting.
Tips
Allergen Overlap Note
Check every packaged ingredient for certified gluten-free status, especially spices, broths, sauces, seed products, and baking staples. Use clean prep surfaces, dedicated utensils, and fresh parchment or cookware when preparing lemon poppy seed cupcakes with dairy-free frosting for someone with celiac disease.
Texture Expectations
Bake until the tops are lightly golden and centers are set but still moist enough to be soft. Let cupcakes cool fully before frosting for a clean finish.
Dining With Non-GF Family Note
Arrange cupcakes in a dedicated gluten-free platter and use separate serving tongs for mixed-diet tables.
