If you’ve got a bag of frozen berries sitting in your freezer and no real plan for them, this is the recipe. It’s a soft, buttery berry coffee cake with berries folded right into the batter and a brown sugar streusel topping baked on top — the kind of thing that makes your kitchen smell incredible.

This one comes together in one bowl, no mixer required, and it’s forgiving enough for a beginner but good enough that nobody’s going to guess it took you 20 minutes to throw together. Serve it warm for breakfast with coffee, or call it dessert later that night — it works either way.

Why You’ll Love This Recipe

• One bowl, no mixer. The crumb base does double duty as both cake and topping.
• Real ingredients only. No boxed cake mix, no shortcuts — just pantry staples.
• Fresh or frozen berries both work, so it’s a good any-season bake.
• Freezer friendly, so you can make it ahead and always have a slice ready.
• Genuinely better than boxed coffee cake — I don’t say that lightly.

What You’ll Need

The base of this cake pulls double duty — part of it becomes the crumb topping, and the rest becomes the cake itself, so you’re really only making one mixture.

• 1 cup granulated sugar
• 1 cup brown sugar, packed (I make my own — here’s my homemade brown sugar recipe if you’ve never tried it)
• 2 cups all-purpose flour
• 1/2 cup unsalted butter, softened
• 1 teaspoon salt
• 2 large eggs
• 1 cup plain Greek yogurt
• 1 teaspoon baking soda
• 2 teaspoons vanilla extract (this is where good vanilla really matters — my homemade vanilla extract is worth the wait if you want to make your own)
• 2 cups mixed berries, fresh or frozen

A 9×13 pan and a good set of mixing bowls make this one easy — these are the ones I use and love.

How to Make Berry Crumb Cake

Make the Crumb Base

In a large bowl, combine the granulated sugar, brown sugar, flour, softened butter, and salt. Mix everything together with a spoon or your hands until it’s crumbly and evenly combined — this is the base for both the cake and the streusel topping, so take your time here. Once it’s mixed, scoop out 1 cup of the mixture and set it aside. That’s your crumb topping.

Mix in the Wet Ingredients

To the bowl with the remaining crumb mixture, add the eggs, Greek yogurt, baking soda, and vanilla extract. Mix until everything is smooth and well combined — you’ll go from a crumbly, dry mixture to a thick, scoopable batter.

Fold in the Berries

Gently fold in the mixed berries. If you’re using frozen berries, don’t thaw them first — mix them in straight from the freezer so they don’t bleed color into the batter.

Assemble and Bake

Butter a 9×13 pan and spread the batter evenly into it. Sprinkle the reserved 1 cup of crumb topping evenly over the top. Bake at 350°F for 50-60 minutes, until a toothpick inserted in the center comes out clean and the top is golden brown.

Cool and Serve

Let the cake cool in the pan for a few minutes before slicing — this gives it a chance to set so your slices hold together. Serve warm or at room temperature.

High Altitude Notes (Baking at 7,053 ft)

This recipe was developed and tested in my Colorado kitchen at 7,053 feet, so if you’re baking at altitude too, you shouldn’t need to change a thing. A few notes either way:

• Thinner air means faster evaporation. At altitude, batter loses moisture quicker in the oven, which is part of why this recipe leans on Greek yogurt — it helps keep the crumb soft instead of drying out.
• Watch the top, not just the clock. Because evaporation happens faster up here, the crumb topping can brown before the center is fully set. If the top looks done at 45 minutes but the center is still jiggly, tent it loosely with foil and keep baking.
• Baking below 3,000 ft? You may find the cake bakes slightly faster and rises a bit more since your air holds more moisture and there’s less pressure difference. Start checking for doneness around the 45-minute mark.

Tips for the Best Berry Crumb Cake

• Use softened, room-temperature butter for the crumb base — cold butter makes it harder to get an even, crumbly texture.
• Don’t overmix once the wet ingredients go in. Mix just until smooth so the cake stays tender.
• Toss frozen berries in a tablespoon of the reserved crumb mixture before folding them in — it helps keep them from sinking to the bottom.
• Always check doneness with a toothpick, not just the timer. Ovens (and altitude) vary.
• Let it cool before slicing. I know it’s tempting, but a rushed cut gives you a crumbly mess instead of a clean slice.

Storage & Reheating

• Room temperature: Cover tightly and store up to 2 days.
• Refrigerator: Up to 5 days, covered.
• Freezer: Wrap individual slices and freeze up to 2 months. Thaw at room temperature or warm gently in the oven at 300 degrees.

Variations to Try

• Single berry: Use all blueberries or all raspberries instead of a mix.
• Bright and citrusy: Add 1 teaspoon lemon zest to the batter.
• Warm and spiced: Add 1/2 teaspoon cinnamon to the crumb topping.
• Gluten-free: Swap in a 1:1 gluten-free flour blend.
• Dairy-free: Use a dairy-free yogurt alternative in place of Greek yogurt.
