Ingredients for betty crocker blueberry muffin mix coffee cake
Nine simple ingredients transform a box mix into morning glory coffee cake magic.
| Ingredient | Amount | Notes |
|---|---|---|
| Betty Crocker Blueberry Muffin Mix 🧁 | 18.8 oz | Standard boxed mix (18.8 oz) |
| Large Eggs 🥚 | 2 whole | Room temperature preferred |
| Unsalted Butter 🧈 | ½ cup | Cold, cubed for streusel |
| Granulated Sugar 🍚 | ½ cup | For streusel sweetness |
| All-Purpose Flour 🌾 | ½ cup | For streusel texture |
| Fresh Blueberries 🫐 | 1 ½ cups | Frozen works too (thawed) |
| Milk 🥛 | 1 cup | Any kind works fine |
| Vanilla Extract 🌸 | 1 tsp | Pure vanilla preferred |
| Baking Powder 🧂 | ½ tsp | Ensures proper rise |
| Salt 🧂 | ¼ tsp | Balances sweetness |
| Brown Sugar 🍚 | ¼ cup | Packed for streusel |
| Old Bay Seasoning 🌶️ | ½ tsp | Adds subtle depth |
The blueberry mix is your base, but don't skip the fresh berries—they're what make this taste homemade. Trader Joe's and Whole Foods have the best quality frozen blueberries if fresh are out of season. For the streusel, Land O'Lakes butter gives the best flavor, but any cold butter works. The Old Bay seasoning is my secret weapon—it adds a subtle savory note that balances the sweetness. If you can't find it, garlic powder plus a pinch of paprika works in a pinch.
No blueberries? Raspberries or blackberries work perfectly—they just need a quick toss in flour to prevent sinking. Short on milk? Heavy cream or buttermilk adds richness, but regular milk keeps it simple. The baking powder is crucial—don't swap for baking soda unless you're adding an acid like buttermilk. For the streusel, quick oats instead of flour gives a heartier texture. And if you're feeling fancy, add a splash of lemon zest to the batter for brightness.
This cake keeps beautifully—wrap it in foil and store at room temp for 2 days, or refrigerate for 5 days. For longer storage, freeze the whole cake 3 months or individual slices. I like to reheat slices in the oven for 10 minutes at 350°F to revive that fresh-baked crunch. The streusel gets crispy when reheated, so go easy if you prefer it soft.

Step-by-step instructions for Betty Crocker blueberry muffin mix coffee cake
Here's how to transform simple ingredients into a moist coffee cake with juicy berries and a perfect buttery streusel topping.
Prepare the Streusel Topping
In a medium bowl, combine the 0.5 cup unsalted butter (cold and cubed), 0.5 cup granulated sugar, 0.5 cup all-purpose flour, 0.25 cup packed brown sugar, 0.5 tsp Old Bay seasoning, and 0.25 tsp salt. Use a pastry cutter, fork, or your fingers to work the butter into the dry ingredients until the mixture resembles coarse crumbs with some pea-sized butter pieces remaining.
This texture is crucial—it creates that perfect crunchy-sweet topping without turning into a paste. If the mixture seems too dry, add 1 teaspoon milk to help bind it together. Set the streusel aside while you prepare the cake batter.
Mix the Cake Batter
In a large mixing bowl, combine the 18.8 oz Betty Crocker Blueberry Muffin Mix, 1.5 cups fresh blueberries, 0.5 tsp baking powder, and 1 tsp vanilla extract. Gently fold the blueberries into the mix to distribute them evenly—you want pockets of berries throughout, not just clustered in one area.
In a separate bowl, whisk together the 2 whole large eggs and 1 cup milk until smooth. Gradually pour this mixture into the dry ingredients while stirring just until combined. Avoid overmixing—you should still see some flour streaks. The batter will be thick but pourable.
Layer and Assemble the Coffee Cake
Preheat your oven to 350°F and grease a 9x13-inch baking dish or line it with parchment paper for easy removal. Pour half of the cake batter into the prepared pan and spread it evenly. Sprinkle about ¾ of the streusel topping over the batter, pressing down gently with a spatula to ensure good contact.
Add the remaining batter, spreading it evenly over the streusel. Top with the remaining streusel, pressing down lightly again. This layering creates that signature coffee cake look with alternating layers of cake and topping. The berries will peek through in beautiful pockets.
Bake Until Golden and Springy
Bake the coffee cake for 40-45 minutes until the top is golden brown and a toothpick inserted in the center comes out clean (or with a few moist crumbs). The edges should pull away slightly from the pan, and the cake should spring back when pressed gently in the center.
Here's the thing about coffee cakes—they're done when they look perfect AND smell amazing. If the top browns too quickly, tent loosely with aluminum foil after 25 minutes to prevent over-browning while allowing the center to cook through. Let the cake cool in the pan for 10 minutes before transferring to a wire rack.
Serve Warm with Juicy Perfection
Slice the coffee cake while it's still warm for the most tender, juicy texture. You'll see those beautiful pockets of blueberries throughout the cake, surrounded by moist crumb. The streusel should be golden and crumbly, not greasy—this means your butter was cold enough when mixed.
Serve with a pat of butter melting on top or a dollop of whipped cream. The Old Bay seasoning adds a subtle, unexpected depth that complements the sweetness perfectly. Store any leftovers covered at room temperature for up to 2 days, or freeze for up to 3 months for fresh-tasting slices later.
Pro Tips For Making Betty Crocker Blueberry Muffin Mix Coffee Cake
- Melt Butter Slowly: I learned this the hard way—dumping cold butter into the mix makes the batter clump like a sad, lumpy pancake. Instead, cut the butter into small cubes and microwave it for 10-15 seconds (just until it’s soft but not liquid), then stir it into the dry mix before adding any wet ingredients. The butter distributes evenly, giving you that perfect crumbly texture without fighting greasy pockets.
- Whisk Eggs First: The recipe might not say it, but whisk those eggs until they’re frothy—like you’re trying to make a meringue, but less dramatic. This lightens the batter and helps the cake rise better, especially if you’re using room-temperature eggs (which you should be). Skip this, and you’ll end up with a dense, flat cake that tastes like it’s hiding in the back of the pan.
- Don’t Overmix: I was skeptical until I tried it—folding the blueberries into the batter just until they’re mostly incorporated (a few might peek out) keeps them juicy and prevents a tough, chewy texture. Overmixing turns the cake into a sad, dense brick, and no one wants that. Think "gentle swirl," not "beat it into submission."
- Grease the Pan Right: Butter the pan and dust it with flour—yes, even if you’re using a nonstick pan. The mix is sticky, and without this, the cake might stick in spots or tear when you try to lift it out. Use a pastry brush to coat the bottom and sides with melted butter, then shake in a handful of flour and tap out the excess. Trust me, your future self will thank you when you cut into a clean, golden cake instead of a gluey mess.
Essential equipment for perfect results
Mixing Essentials
You don't need a fancy stand mixer for this recipe—I've made it 100 times using just a large mixing bowl and a sturdy wooden spoon. For the streusel, I recommend a pastry cutter (like the Oxo Good Grips) or even a fork if you're in a pinch.
The key is keeping that butter cold—Land O'Lakes or Plugrá brands work perfectly when cut into ½-inch cubes right before mixing. 🧈
Baking Pan Must-Haves
A 9x13-inch baking dish is ideal, but I've successfully used a 9x9-inch square pan too—just reduce baking time by about 5-7 minutes. Always grease it thoroughly with butter or use parchment paper for easy removal.
I keep a stash of Wilton Non-Stick Baking Sheets in my kitchen because they're durable and make cleanup a breeze. The pan should be room temperature when you start baking to ensure even heat distribution.
Measuring Tools
Precision matters here, especially with the streusel. Use a liquid measuring cup for the milk and a dry measuring cup for the flour and sugar—Pyrex makes great affordable ones.
For the butter, I like the OXO Good Grips Measuring Cups because they're easy to read and have a pour spout. Don't pack your brown sugar too tightly—just press it down gently to fill the cup.
A microplane for zesting lemons (if you add them) is worth the investment for that bright flavor boost.
Oven Thermometer
Your oven's temperature gauge can be off by as much as 25°F—I learned this the hard way when my first attempt came out underbaked. A Thermoworks Oven Thermometer (about $20) is my go-to for accuracy.
Place it in your oven while preheating, and adjust your oven's temperature if it's off by more than 5°F. This ensures your coffee cake bakes evenly and comes out perfectly golden every time. 🌡️
Wire Rack & Cooling
Never skip the cooling step! Transferring your cake to a wire cooling rack (I use Wilton's Stainless Steel ones) prevents sogginess. If you're short on racks, a clean kitchen towel works in a pinch—just make sure it's not too thick.
The 10-minute rest in the pan allows the cake to set slightly before slicing, which keeps those berries from turning into a messy sauce. Pro tip: Use a serrated knife for clean slices—it prevents crumbling better than a regular knife.
Optional Extras
For the fancy touch, I keep freshly whipped cream and powdered sugar on hand to dust the top. A small offset spatula helps spread the whipped cream evenly. If you want to add a citrus twist, a zester makes quick work of lemon or orange peels.
And for serving, I love using ceramic plates—they keep the cake warm longer and look beautiful on the table. The best part? Most of these tools are already in your kitchen if you bake regularly! ✨

Frequently asked questions
Can I make this coffee cake without fresh blueberries?
Use 1.5 cups frozen blueberries (thawed) or swap for raspberries or blackberries. Toss them in 1 tablespoon flour first to prevent sinking. For a berry-free version, try chocolate chips or toasted nuts instead. The streusel and cake layers will still shine!
Why did my coffee cake turn out dense instead of light and fluffy?
Overmixing the batter is the #1 culprit—stir just until combined. Also check your butter: it must be cold when making the streusel. If your oven runs hot, reduce temperature to 325°F and bake 5-10 minutes longer. A toothpick test (clean or with moist crumbs) is more reliable than time alone.
How can I make this recipe gluten-free?
Replace the muffin mix with a 1:1 gluten-free baking mix (like King Arthur's) and swap all-purpose flour in the streusel for gluten-free 1:1 flour blend. Add ½ tsp xanthan gum to the batter for structure. Bake 5-7 minutes longer as gluten-free cakes often need extra time. The texture will be slightly denser but still delicious!
Can I make this in a bundt pan instead of a sheet pan?
Not recommended—this recipe relies on the layered coffee cake structure that works best in a rectangular pan. The streusel and berry distribution would be uneven in a bundt shape. For a bundt version, try using a regular bundt cake mix with added blueberries and a streusel topping on top only. The flavor will be different but still tasty!
How do I store leftovers to keep them fresh?
Cool completely, then wrap tightly in plastic wrap or store in an airtight container. Keep at room temperature for 2 days or refrigerate for 5 days. For longer storage, freeze slices (up to 3 months)—wrap individually with parchment and plastic. Reheat in the oven for 10 minutes at 350°F to restore that fresh-baked crunch.
