Grandma’s Blackberry Cake

I remember going berry picking with Mom and Grandma. Even at 70 years old, Grandma could pick 3 gallons of berries before I had my pail half full. Grandma made up this blackberry cake recipe with her mom, and it's been passed down for five generations now. —Diana Martin, Moundsville, West Virginia

    I doubled the recipe and made a 9X11 cake and 12 cupcakes. I followed the recipe and they all came out great. I think next time I make this recipe I will add extra blackberries. I have not frosted, but may frost with a light frosting, but frosting is not necessary.

    We harvest a lot of blackberries from our bushes every summer. This is one of my husband's favorite blackberry desserts

    Excellent recipe. I made this three times in a week and everybody I shared it with loved it, too. Doesn't need icing. Made it just as written.
