- 1 cup granulated sugar
- 1 tablespoon baking powder
- 1/2 teaspoon salt
- 1/4 cup poppy seeds
- 1 cup milk
- 1/2 cup vegetable oil
- 2 large eggs
- 1 teaspoon vanilla extract
Ingredient Notes and Substitutions
- All-purpose flour: This provides the structure. You can use a gluten-free blend if needed.
- Granulated sugar: Adds sweetness and moisture. Brown sugar can be used for a deeper flavor.

How to Make Costco Poppyseed Muffin Recipe
Step 1: Preheat the Oven
Start by preheating your oven to 350°F (175°C). This ensures your muffins bake evenly from the moment you pop them in.
Step 2: Prepare the Muffin Tin
Line a muffin tin with paper liners or spray it with cooking spray. This prevents sticking and makes clean-up a breeze.
Step 3: Mix the Dry Ingredients
In a large mixing bowl, whisk together the flour, sugar, baking powder, salt, and poppy seeds. Mixing the dry ingredients first helps distribute the leavening agent evenly.
Step 4: Combine the Wet Ingredients
In another bowl, mix the milk, vegetable oil, eggs, and vanilla extract. This step ensures a smooth batter without lumps.
Step 5: Combine Wet and Dry Mixtures
Pour the wet ingredients into the dry ingredients. Stir gently with a rubber spatula until just combined; over-mixing can lead to dense muffins.
Step 6: Fill the Muffin Tin
Divide the batter evenly among the muffin cups, filling each about two-thirds full. This gives them room to rise without overflowing.
Step 7: Bake the Muffins
Place the muffin tin in the preheated oven and bake for 18 to 20 minutes. They are done when a toothpick inserted in the center comes out clean.
Step 8: Cool and Enjoy
Allow the muffins to cool in the tin for a few minutes before transferring them to a wire rack. This helps them set and makes them easier to handle.
Pro Tip: For extra flavor, try adding lemon zest to the batter!
Tips for the Best Costco Poppyseed Muffin Recipe
- Use room temperature ingredients for a smoother batter.
- Don’t skip the cooling step; it enhances the texture.
- Experiment with add-ins like blueberries or chocolate chips for variety.
- To keep muffins fresh, store them in an airtight container.
- For a crunchy top, sprinkle some sugar before baking.
Common Mistakes to Avoid
- Over-mixing the batter can lead to tough muffins. Stir until just combined.
- Not preheating the oven can result in uneven baking. Always preheat for consistent results.
- Filling muffin cups too full causes overflow. Stick to two-thirds full for best results.
- Skipping the cooling time can make them soggy. Give them a chance to set on a wire rack.
