How To Make Costco Coffee Cake Muffin

Okay, let’s break this down step-by-step. I promise it’s straightforward, but I’ll explain everything so your kitchen smells like a coffee shop in no time.

1. Prep Your Oven And Pans

   • Preheat your oven to 350°F (175°C).
   • Line a 12-cup muffin tin with paper liners or grease it lightly.

2. Make The Crumb Topping

   • In a small bowl, combine flour, brown sugar, cinnamon, and a pinch of salt if you like.
   • Cut in the cold cubed butter using a pastry cutter or two forks until the mixture resembles coarse crumbs. Set aside.

3. Mix Dry Ingredients For Muffins

   • In a large bowl, whisk together flour, sugar, baking powder, baking soda, salt, and cinnamon until well combined.

4. Mix Wet Ingredients

   • In a separate bowl, whisk eggs, milk, melted butter, and vanilla extract until smooth.

5. Combine Wet And Dry

   • Pour wet ingredients into dry and gently fold together with a spatula or wooden spoon.
   • Be careful not to overmix – a few lumps are totally fine. Overmixing = tough muffins.

6. Fill Muffin Cups

   • Divide the batter evenly among the 12 muffin cups (about ¾ full).

7. Add The Crumb Topping

   • Generously sprinkle the crumb topping over each muffin – this is the best part!

8. Bake

   • Bake for 22-25 minutes or until a toothpick inserted into the center comes out clean or with just a few moist crumbs.

9. Cool And Enjoy

   • Let muffins cool in the pan for about 5 minutes, then transfer to a wire rack.
   • Try to wait until they’re just warm – but honestly, warm or not, they’re irresistible.

Ingredient Science Spotlight

This part is fun because understanding why ingredients do what they do can seriously up your baking game!

• Flour: The protein (gluten) in all-purpose flour provides the structure and chewiness. Too much mixing develops gluten, making muffins tough – that’s why gentle folding is key!
• Baking Powder & Baking Soda: Both are leavening agents. Baking powder is double-acting – it reacts when wet and again when heated. Baking soda requires acid in the batter (like brown sugar or cinnamon) to activate, producing bubbles that lighten the texture.
• Butter: Melted butter adds richness and moisture, but since it’s melted, it results in a more tender crumb rather than a flaky one (which you’d get with cold butter).
• Brown Sugar in Topping: Contains molasses, giving the crumb topping a deeper flavor and extra moisture that helps it stay crumbly but not dry.
• Cinnamon: Beyond flavor, cinnamon adds warmth and subtle sweetness – it also pairs beautifully with the buttery topping.

Expert Tips

Because I want your muffins to be absolutely perfect, here are some pro tips:

• Don’t Overmix the Batter: This cannot be stressed enough. Fold gently until ingredients are just combined.
• Use Fresh Leavening: Baking powder and soda lose potency over time, so check their freshness to ensure a nice rise.
• Chill the Topping Butter: Cold butter chunks create that crumbly texture when baked.
• Room Temperature Eggs & Milk: Helps the batter mix more evenly, producing a lighter muffin.
• Avoid Overbaking: Keep a close eye on the oven after 20 minutes to prevent drying out.

Recipe Variations

Feeling adventurous? Here are some fun twists on the classic Costco Coffee Cake Muffin:

• Blueberry Cinnamon Coffee Cake Muffins: Fold in 1 cup fresh or frozen blueberries into the batter before baking.
• Chocolate Chip Coffee Cake Muffins: Add ½ cup mini chocolate chips to the batter for a chocolatey surprise.
• Nutty Crunch: Mix ½ cup chopped pecans or walnuts into the crumb topping for extra crunch and flavor.
• Gluten-Free Version: Substitute all-purpose flour with a gluten-free blend, and add ½ teaspoon xanthan gum for structure.
• Vegan Adaptation: Replace eggs with flax eggs (1 tablespoon flaxseed meal + 3 tablespoons water each), use plant-based milk, and vegan butter or coconut oil.

Final Words

Look, the joy of baking something from scratch, especially when it tastes like a beloved bakery staple, is pretty incredible. These Costco-style Coffee Cake Muffins are a testament to how simple ingredients, a little technique, and a sprinkle of love can make mornings infinitely better.

Whether you’re making them for a brunch, a cozy weekend breakfast, or just because you deserve a treat, these muffins will not disappoint. Plus, the crumb topping? Honestly, it’s the showstopper. That crunchy, cinnamon-sugar goodness is what turns a regular muffin into a coffee cake experience.
