Ingredient Checklist


Instructions Checklist
  • Preheat oven to 350 degrees. Lightly butter a 5-by-9-inch loaf pan and line with parchment, leaving a 2-inch overhang on all sides; butter parchment. In a food processor, puree blackberries with 2 tablespoons sugar. In a medium bowl, whisk together flour, salt, and baking powder.

  • In a large bowl, using an electric mixer, beat together butter and 1 1/4 cups sugar until light and fluffy, 5 minutes. Add eggs and vanilla and beat to combine, scraping down bowl as needed. With mixer on low, add flour mixture in 3 additions, alternating with sour cream, beginning and ending with flour mixture.

  • Transfer half the batter to pan and dot with 1/2 cup blackberry puree. Repeat with remaining batter and puree. With a skewer or thin-bladed knife, swirl batter and puree together. Bake until golden brown and a toothpick inserted in center of cake comes out clean, about 1 1/4 hours. Let cool in pan on a wire rack, 30 minutes. Lift cake out of pan and place on a serving plate; let cool completely before slicing.

Cook's Notes

Store cooled cake, wrapped tightly in plastic, at room temperature, up to 3 days. Change it up: Swap 6 ounces raspberries or blueberries for the blackberries.

Maybe I don't know how to puree blackberries. I ended up with blackberry syrup; they were very ripe. I also ended up baking it for almost an hour. Quite disappointed in taste & texture. Very heavy dense cake which takes away from the blackberry taste. Don't think I'll be making this one again.

My 8 year old son and I made this delicious cake. It's not a typical dry pound cake. The blackberries help the cake to be moist. Great taste and simple to make.

Used my blackberries from my small bush to create beautiful pound cakes. I added cream cheese to the batter, yummers!!!

This pound cake recipe is a keeper! I used farmer's market blackberries and it came out moist and delicious. I will try blueberries next time.

Back at it again. I have tried other recipes for pound cake and have not found one that is this moist, this delicious or this weighty. This is now our go to recipe when guests come over. So expect it when you show up.

I took this recipe from my Everyday Food Magazine, issue 74 and it's really delicious, althoug i recommend to strain the puree to remove seeds and also use only half puree in the center of the pound cake because tends to burn on the top. Also i really would like to try using blueberries, yumm!!

This is my fifth time making this recipe. We have the ability to pick black berries by the gallons in our back yard and this has become the staple cooked gift we bring to friends houses, party's, co workers, or anywhere it is acceptable to gift cooked food. It is moist, well flavored, and the berry swirl is tasty and sweat. It is real good with vanilla gelato.

I went Blackberry picking with my brother on a beautiful August day and then realized I had no good recipes to use them in. I made this, my first ever pound cake, and it was AMAZING! the house smelled SO good while it was in the oven & one taster even suggested it be entered in the local fair's baking category! Delicious and unique~
