Prep and Cook Time
- Prep Time: 15 minutes
- Cook Time: 20 minutes
- total time: 35 minutes
Yield
12 generously sized muffins
Difficulty Level
Easy – perfect for bakers of all skill levels
Ingredients
- 2 cups all-purpose flour, sifted
- 1 cup granulated sugar
- 2 tsp baking powder
- ½ tsp baking soda
- ¼ tsp salt
- 2 tbsp poppyseeds, whole and lightly toasted
- 1 cup buttermilk, well shaken
- ½ cup unsalted butter, melted and cooled
- 2 large eggs, room temperature
- 1 tsp pure vanilla extract
- 1 tbsp finely grated lemon zest for brightness
Instructions
- Preheat your oven to 375°F (190°C). Line a 12-cup muffin tin with paper liners or lightly grease with butter.
- Toast the poppyseeds in a dry skillet over medium-low heat for 2-3 minutes until fragrant. Stir constantly to avoid burning. Set aside to cool.
- In a large bowl, combine the sifted flour, sugar, baking powder, baking soda, salt, and toasted poppyseeds.Whisk together to ensure even distribution.
- In a separate bowl, whisk the eggs, buttermilk, melted butter, vanilla extract, and lemon zest until smooth and well combined.
- Pour the wet ingredients into the dry ingredients and stir gently with a spatula. Mix just until the batter is combined; a few lumps are fine-overmixing toughens muffins.
- Spoon the batter evenly into the muffin tin,filling each cup about ¾ full to allow room for rising.
- Bake for 18-20 minutes or until the tops are golden and a toothpick inserted into the center comes out clean. Rotate the tin halfway through baking for even colour.
- Cool muffins in the pan for 5 minutes, then transfer to a wire rack to cool completely before serving.
Chef’s Notes: Tips for Success
- Use fresh poppyseeds. Stale poppyseeds lose their crunch and aroma, so buy them fresh and toast lightly for maximum flavor impact.
- Substitution for buttermilk: Mix 1 cup milk with 1 tbsp lemon juice or white vinegar; let sit 5 minutes to curdle.
- Don’t overmix the batter. This keeps muffins tender and fluffy instead of dense and chewy.
- Make-ahead tip: muffins freeze well in an airtight container for up to 2 months. Thaw at room temperature or warm gently in the microwave.
- Try adding a subtle drizzle of lemon glaze (powdered sugar + lemon juice) after baking to enhance the citrus notes without overpowering.
Perfect Pairings and Serving Suggestions
Costco’s poppyseed muffins shine when paired with rich,creamy coffee or a freshly brewed cup of Earl Gray tea,sealed with a squeeze of lemon to complement the zingy poppyseed flavor. for brunch, serve warm alongside a dollop of mascarpone or cream cheese and a few fresh berries to add a pop of color and juicy contrast.
A light smear of honey butter or tangy lemon curd elevates the experience, creating a perfect balance between sweet, tart, and nutty textures. for iced mornings, these muffins can also be split and toasted gently, thickly layered with tangy Greek yogurt and a scatter of toasted almonds.
