About Oregon Blackberries
Oregon was made for growing blackberries. Warm summer days, cool nights, and the clean, fertile soil make Oregon the perfect climate! You can find valuable information about Oregon blackberries, recipes, and the farmers at Oregon-berries.com.
Oregon blackberries are grown on multi-generational family farms by local families who genuinely care about the land. These growers follow environmentally sustainable practices that support the health of the soil and the community around them. When you bake with Oregon blackberries, you're supporting that entire chain from the farm family to your kitchen table.
What makes frozen Oregon blackberries such a reliable choice is the process behind them. The berries are picked at the peak of ripeness and flash frozen within 24 hours. That means the flavor and color you get in the bag is as close to fresh from the field as it gets. The nutrition is locked in for the win if you're looking for ingredients that taste great and do good things for your body. You can find them year-round at a consistent quality and price, which makes them one of the smartest things to keep stocked in your freezer

What Makes This Recipe Work
Butter in the cupcake batter - This recipe uses a reverse creaming method, meaning butter goes into the dry ingredients first. Cut it into pieces and let it come to room temperature so it beats in evenly. This technique gives you a fine, tender crumb that holds up under all that frosting.
Room temperature eggs and milk - Cold ingredients do not incorporate together easily. Cold ingredients can also cause your cake to bake unevenly. Pull them out about 30 minutes before you start baking and you'll get a much smoother, fluffier result.
Full-fat cream cheese for the frosting - Don't swap this out for a lower-fat version. Full-fat cream cheese gives the frosting structure and that signature richness that balances the sweetness of the blackberries. Let it come to a cool room temperature, not too warm or the frosting can get loose.
Oregon blackberries - You'll puree them and strain out the seeds for the frosting. What you're left with is a concentrated, jewel-toned puree that flavors and colors the frosting naturally. If you're using frozen Oregon blackberries, thaw and drain them well before pureeing. The flash-frozen process means they hold their color and flavor, so the frosting comes out just as vibrant as it would with fresh berries.
How To Make Blackberry Crumble Cupcakes
Make the crumble first. Stir the flour, brown sugar, and salt together in a medium bowl. In a separate bowl, combine the melted butter and vanilla, then pour a little at a time over the dry ingredients. Stir with a fork until the butter has moistened everything, then toss to break up the clumps. Set it aside while you prepare the rest of the ingredients. If it is too soft, put it in the refrigerator for 5 minutes.
Fill each liner about three-quarters full. Don't go higher or they'll overflow and lose their shape. Bake for 18 to 20 minutes, rotating the pan halfway through. A toothpick inserted into the center should come out with just a few moist crumbs. Cool in the pan for 10 minutes, then transfer to a wire rack to cool completely. Don't rush this step or your frosting will slide right off.
Make the blackberry frosting. Puree 1 cup of Oregon blackberries in a food processor, then push the puree through a fine mesh strainer to remove the seeds. You'll end up with a few tablespoons of smooth, vibrant puree. Beat the butter, confectioners' sugar, and 3 tablespoons of the blackberry puree together on low speed until smooth, scraping the bowl a few times. Mix in the salt. Then turn the speed up to medium and beat until the frosting is light and fluffy, about 3 minutes.
Frost and finish. Use a piping bag and tip of your choice to add frosting to each cupcake. I used an open star tip and a large round tip. Then sprinkle the crumble generously over the top. Finish with a whole blackberry and a blackberry flower if you have them. Those little flowers are optional, but they make these cupcakes look stunning. If you grow blackberries in the garden, you likely already have access to them!

Tips and Variations
Make it ahead. You can bake the cupcakes a day ahead and store them unfrosted at room temperature. Make the frosting and crumble the day of. Frost and finish just before serving for the freshest look and texture.
Frosting too Soft? If your kitchen is warm and the frosting feels too soft, pop it in the fridge for 10 to 15 minutes before piping.
Add lemon zest. A little lemon zest stirred into the frosting brightens everything up and plays really well with the blackberry flavor. Don't be shy about trying it.
Storage
Store frosted cupcakes in an airtight container in the refrigerator for up to 3 days. Because of the cream cheese frosting, they do need to be kept cold. Let them sit at room temperature for about 15 to 20 minutes before serving so the frosting softens up and the cupcake texture comes back to life. Unfrosted cupcakes can be stored at room temperature in an airtight container for up to 2 days, or frozen for up to a month. Wrap them individually before freezing for the best results.

FAQs
Absolutely, and they work great here. Oregon blackberries are flash frozen and picked at peak ripeness, so the flavor and color hold up really well. Thaw them completely and drain off any excess liquid before pureeing. The frosting will come out just as vibrant.
A zip-top bag with the corner snipped off works just fine. You can also use an offset spatula to spread the frosting. It'll look more rustic but still delicious.
After straining, you'll have about 3 to 4 tablespoons of smooth puree. That's exactly what you need for the frosting, with a little left over to drizzle on top if you'd like.
Frozen Oregon blackberries are available year-round in most grocery stores, which is one of the things I love most about keeping them stocked. Just look for "Grown in the USA" on the packaging, over 95% of frozen blackberries grown in the USA are from Oregon! It's one of the best value swaps in the freezer aisle.

Final Thoughts
Blackberry Crumble Cupcakes feel like a Summer celebration. Fruity, creamy, buttery, and finished with that irresistible crumble, every component earns its place. Oregon blackberries make the frosting truly special, and knowing those berries came from family farms that have been tending the land for generations makes baking with them feel even better.
