Ingredients for anthony's blueberry coffee cake
A tender cake meets a buttery streusel—juicy blueberries tie it all together.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 2 ½ cups | Sifted for light texture |
| Granulated Sugar 🍚 | 1 ½ cups | White or light brown |
| Light Brown Sugar 🍚 | ½ cup | Packed firmly |
| Unsalted Butter 🧈 | 1 cup | Cold, cubed for streusel |
| Fresh Blueberries 🫐 | 1 ½ cups | Washed and dried |
| Large Eggs 🥚 | 2 whole | Room temperature |
| Vanilla Extract 🌿 | 1 tbsp | Pure, high-quality |
| Baking Powder 🧂 | 2 tsp | Diamond Crystal preferred |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Ground Cinnamon 🌶️ | 1 tbsp | Freshly ground preferred |
| Old-Fashioned Rolled Oats 🌾 | ½ cup | Blended into flour |
| Milk 🥛 | 1 cup | Whole milk preferred |
| Vegetable Oil 🫒 | ½ cup | Light or neutral oil |
The butter is the star here. European-style unsalted butter (like Plugrá or Land O’Lakes European) gives that rich, caramelized flavor in the streusel, but any good-quality butter works. For the blueberries, wild blueberries from Trader Joe's or Costco pack the most flavor, but regular ones work too—just toss them in a bowl with a tablespoon of flour to keep them from sinking. The oats? Old-fashioned rolled oats blend better than quick oats for that perfect crumbly texture. If you're short on time, pulse them in a food processor for a finer streusel.
No vanilla extract? Vanilla bean paste works in a pinch (use half the amount), or scrape seeds from a vanilla bean. The baking powder needs to be fresh—if it's more than six months old, test it first (mix with water; it should bubble). For a vegan twist, swap the eggs for flax eggs (2 tbsp ground flax + 6 tbsp water, rested 5 mins). The milk can be swapped for almond or oat milk, but whole milk keeps the cake moist. And if you're out of brown sugar, white sugar plus 1 tsp molasses gets you close.
This cake keeps well at room temperature for 2 days in an airtight container, but it’s best enjoyed fresh. For longer storage, wrap tightly and refrigerate for up to 5 days. Freeze slices for 3 months—just thaw at room temperature before serving. Pro tip: Brush warm slices with a little melted butter and sprinkle with powdered sugar for extra bakery-style flair. The streusel stays crisp for days, so no need to rush eating it.
Why You'll Love This Recipe
- No Mixer Needed: I swear by this recipe because it’s actually mixable by hand—no stand mixer or food processor required. The butter gets cut into the flour and sugars until it’s crumbly but not greasy, and the blueberries stay plump without needing to be tossed in flour first. Honestly, it’s the kind of recipe that makes me feel like a baking pro, even when I’m just using a wooden spoon.
- Butter + Brown Sugar Magic: That combo of light brown sugar and cold butter? It’s what turns this into something dangerously addictive. The cake has this just-right tenderness with a subtle caramel depth, while the blueberries pop with every bite. Between us, I’ve made this with frozen berries in a pinch, but fresh? It’s a whole other level of good.
- Brunch or Snack Fix: I’ve served this warm with a scoop of vanilla ice cream for Sunday brunch, sliced into squares for office potlucks, and even sent pieces in lunchboxes for my kids’ school events. The recipe scales easily—double it for a crowd, halve it for a quick treat—and it reheats beautifully. (Yes, even on a Tuesday night.)
- Leftovers That Don’t Suck: Most coffee cakes dry out or turn gummy, but this one? It stays moist for days if you store it properly. I’ll wrap the whole thing in foil and stash it in the fridge, then slice and toast slices the next morning. Plus, the butter and sugar cost next to nothing—it’s my go-to when I want something indulgent without breaking the bank.
Step-by-step instructions for Anthony's blueberry coffee cake
A perfect balance of tender cake, juicy blueberries, and crumbly streusel—all baked in one pan.
Prepare the Blueberry Filling and Cake Batter
In a medium bowl, gently toss the 1.5 cups fresh blueberries with 1 tablespoon granulated sugar (reserved from the 1.5 cups total). This sweetens the berries without making the cake too dense. Set aside while you prepare the batter.
In a separate large bowl, whisk together the 2.5 cups all-purpose flour, 2 teaspoons baking powder, ½ teaspoon salt, and 1 tablespoon ground cinnamon. Sift the dry ingredients lightly to aerate them—this ensures a lighter, fluffier cake. In another bowl, beat the 2 whole large eggs until smooth, then whisk in the 1 cup milk, ½ cup vegetable oil, 1 tablespoon vanilla extract, 1.5 cups granulated sugar, and ½ cup light brown sugar until fully combined. Gradually fold the dry ingredients into the wet mixture until just combined, being careful not to overmix.
Assemble the Coffee Cake in the Pan
Preheat your oven to 350°F and grease a 9x13-inch baking pan lightly with butter or nonstick spray. Pour half of the cake batter into the prepared pan, spreading it evenly. Sprinkle half of the blueberry mixture over the batter, gently pressing it down slightly so the berries release their juices into the cake. Repeat with the remaining batter and blueberries, creating a second layer.
Here's the thing—don't press the berries too hard or they'll burst, making the cake soggy. Just a light touch ensures they stay intact while still contributing their juices to the cake.
Make the Streusel Topping and Assemble
In a food processor or by hand, pulse the ½ cup old-fashioned rolled oats until they resemble coarse flour. In a small bowl, combine the oat flour with ½ cup all-purpose flour, ½ cup light brown sugar, ½ cup cold cubed unsalted butter, and 1 teaspoon ground cinnamon. Use your fingers or a fork to work the butter into the dry ingredients until it resembles coarse crumbs with some pea-sized pieces remaining. This texture is key—it should be crumbly but still hold together.
Sprinkle the streusel evenly over the top of the cake batter, pressing down gently with your fingers to ensure even coverage. The streusel should look like a patchwork of golden-brown clusters when baked. Bake for 45-50 minutes, or until a toothpick inserted into the center comes out clean and the streusel is golden brown.
Cool and Serve for Maximum Enjoyment
Let the coffee cake cool in the pan for 10 minutes—this prevents it from collapsing as it sets. Then transfer it to a wire rack to cool completely. The cake will be warm, moist, and fragrant, with a crisp streusel topping that contrasts beautifully with the tender cake layers.
I like to serve this coffee cake warm with a pat of butter or a dollop of whipped cream. The blueberries stay juicy, the cake remains moist, and the streusel adds a delightful crunch with every bite. Store any leftovers in an airtight container at room temperature for up to 2 days or refrigerate for up to 4 days. Reheat slices in the oven at 300°F for 5-10 minutes to restore the streusel's crispiness.
Pro Tips For Making Anthony'S Blueberry Coffee Cake
- Toss Blueberries Dry: Dump those berries straight into the flour mix—no rinsing, no sugar bath. I learned this the hard way after making a sticky mess with wet berries, and the cake still bursts with flavor. The natural juices get absorbed into the batter, keeping the texture light.
- Cream Butter Cold: Take that butter straight from the fridge—no softening at room temp. Cold butter creates pockets for the brown sugar to cling to, giving you that perfect crumb. I used to rush this, and the cake turned out dense. Trust me, leave it chilled.
- Skip Overmixing: Stir the batter just until the flour disappears—maybe 15 seconds past that. Overmixing develops gluten, and your coffee cake will turn out tough instead of tender. Fold in those blueberries gently, like you’re tucking in a baby.
- Bake Until Golden: Pull the cake when the edges are set but the center still jiggles slightly—about 55-60 minutes at 350°F. Overbaking dries it out, and underbaking leaves a gummy mess. A toothpick with a few moist crumbs? That’s the sweet spot.
Storing and reheating your leftovers
Room Temperature Storage
Your freshly baked Anthony’s blueberry coffee cake stays fresh and moist for up to 2 days at room temperature when stored in an airtight container. I use a glass Pyrex loaf pan cover or a plastic container with a tight seal to keep the streusel from drying out.
The key is to let it cool completely first—this prevents condensation from making the cake soggy. Place it on a wire rack for 30 minutes before sealing to avoid steam buildup. 💛
Refrigerator Storage
For longer storage, refrigerate the cake in an airtight container for up to 5 days. The cold helps preserve the streusel’s crispness and keeps the cake from drying out.
When ready to serve, let slices sit at room temperature for 10-15 minutes before enjoying—this restores the streusel’s texture and makes the cake more tender. I often reheat individual slices in the oven to revive the streusel’s crunch.
Freezing for Later
Freeze the coffee cake for up to 3 months by wrapping it tightly in plastic wrap followed by a layer of aluminum foil. This double-layer protection prevents freezer burn and keeps the streusel from absorbing odors.
To thaw, leave it at room temperature for 2-3 hours or reheat slices directly from frozen in the oven at 300°F for 10-12 minutes. The texture remains surprisingly fresh!
Reheating Perfection
For the best results, reheat slices in a 350°F oven for 5-10 minutes to restore the streusel’s crispness. I place slices on a baking sheet lined with parchment paper and cover them loosely with foil to prevent over-browning.
A quick zap in the microwave (20 seconds) works in a pinch, but it softens the streusel slightly. Always reheat to 165°F for food safety.
Serving Warm Tips
Serve warm slices with a pat of European-style butter (like Plugrá) or a dollop of whipped cream to enhance the flavors. For extra indulgence, dust with powdered sugar or drizzle with warm maple syrup.
The contrast of warm cake, juicy blueberries, and crisp streusel makes every bite feel like a bakery treat. Save the best slices for breakfast the next morning—they taste even better cold with a cup of coffee! ☕

Frequently asked questions
Why does Anthony's blueberry coffee cake have two layers of batter with blueberries?
This layering creates the signature texture that makes it special. The first layer soaks up juices from the blueberries, while the second layer stays lighter and fluffier. The berries release their juices gradually, keeping the cake moist without becoming soggy. Plus, it gives you that perfect balance of tender cake and plump, juicy berries in every bite!
Can I substitute frozen blueberries for fresh ones?
Yes, but you’ll need to thaw and drain them first! Frozen blueberries work well, but they release more water when thawed. Toss them with 2 tablespoons cornstarch before adding to the batter to absorb excess moisture. This prevents a watery cake. For best results, use fresh berries—they hold their shape better and add that bright, juicy flavor.
How do I know when the streusel is perfectly baked?
The streusel should be golden brown with some caramelized spots, but not burnt. Insert a toothpick into the center of the cake—it should come out clean. The streusel should also hold its shape when pressed gently with a fork, not crumble into fine powder. If it looks pale, bake for another 5-10 minutes until golden.
What if my cake turns out too dense? Overmixing the batter or using old baking powder are the most common culprits.
Can I make this coffee cake in a different pan size?
Yes, but you’ll need to adjust the baking time. For an 8x8-inch pan, bake for 35-40 minutes, and for a 9x9-inch pan, aim for 40-45 minutes. The cake should be golden brown and a toothpick inserted in the center should come out clean. Just keep an eye on it—smaller pans may bake faster, while larger ones might need extra time.
