This mixed berry coffee cake is tender, made with Greek yogurt, and filled with fresh-picked black raspberries and blackberries. It is then topped with a crunchy brown sugar crumble.

The other day, I was walking down a path and spotted a wild black raspberry bush with my little eye. I immediately knew I had to harvest a few to enjoy!
So, I chugged my coffee down, cleaned the cup as best I could, and got to picking! It was a thorny job, but I got it done. Black raspberries are one of my favorite berries, but I have never seen them in the grocery store. That’s why I knew I had to take a little wild harvest.
After I got home, I ate the majority straight from the bowl, but I saved a half cup to put in this delicious mixed berry coffee cake. I probably should have saved more, but I couldn’t resist eating them.
Don’t worry if you can’t find black raspberries for this recipe. You can use blueberries or raspberries or double the blackberries.

My Pro Tips
Recipe Tips
- Use fresh berries that aren’t too soft for this cake. That way, the berries stay whole in the cake.
- Sprinkle the top with powdered sugar to give it an extra level of flair.
- Let the cake fully cool before cutting into it. It may crumble if you cut into it while it’s still warm.
- Warm it up for 30 seconds before serving for a warmed cake treat.
Substitutions and Adaptations
Since this mixed berry coffee cake is a baking recipe, you’ll want to follow it thoroughly. However, here are a few basic things you can change that won’t affect the cake.
- You need a total of 1 cup of berries for this cake. Feel free to use whatever combination of berries you like. Raspberries, blueberries, or blackberries are the easiest berries to find.
- Instead of vanilla bean paste, you could use vanilla or almond extract.
- If you want a more vibrant citrus flavor, try replacing the vanilla bean paste with lemon extract.
- Add up to 1/4 cup chopped pecans to the topping mixture.
