Granny Rose’s Southern Jam Cake

I have adapted this recipe from one that mystery fan and blogger/reviewer Kathy Boone Reel kindly provided, courtesy of her mother. Adele makes the cake, and then Robbie makes a sheet version for a lunch special.


  • 1 stick butter
  • 1 cup sugar
  • 2 eggs
  • 2 teaspoons cocoa
  • 2 teaspoons cinnamon
  • 1 teaspoon cloves
  • 1 teaspoon nutmeg
  • 1 teaspoon baking soda
  • 1½ cups flour
  • ½ cup buttermilk
  • 1 cup seedless blackberry jam


Preheat oven to 350 degrees F. Butter and flour a 9” x 13” pan or two 9” cake pans.

Cream butter and sugar, and then beat in eggs. Mix cocoa, spices, and baking soda into the flour.

Alternately add the flour mixture and the buttermilk to the dry ingredients in three portions, mixing well after each addition. Fold in the preserves. Bake at 350 degrees for half an hour or until a toothpick inserted in the middle comes out clean. Cool and frost with Caramel Frosting, next page. Makes two layers, or one sheet cake.

Caramel Frosting


  • ½ cup butter
  • 1 cup brown sugar (packed)
  • ¼ cup milk
  • 2 cups sifted confectioner’s (powdered) sugar
  • 1 teaspoon vanilla


Melt butter in saucepan. Stir in brown sugar. Add the milk and continue stirring until it comes to a boil.

Remove from heat and cool to lukewarm. Add the powdered sugar and vanilla while beating with mixer on low speed. Beat on high speed until right spreading consistency. If it gets too hard, add a few drops of hot water. If not hard enough, add more powdered sugar. If making a layer cake, frost the bottom half and then the entire cake.

Robbie Jordan’s rustic country store is growing in popularity. But when a dead body appears, it turns out that Robbie’s home-style cooking attracts hungry customers—and murder!
While Robbie scrambles through breakfast orders for her expanding clientele at Pans ‘N Pancakes, tempers run as high as the sticky August heat in South Lick, Indiana. Real-estate developer Fiona Closs plans to build a towering luxury resort at one of the most scenic hilltops in Brown County, and not everyone can see the sunny side of the imposing proposition—including Robbie’s furious Aunt Adele, who doesn’t waste a minute concocting protests and road blockades. When tensions boil over and a vocal protester is silenced forever at the resort site, Robbie ditches the griddle to catch the killer. But if slashed tires are any indication, she’ll need to crack this case before her own aunt gets served something deadly next . . .
