In An American Marriage, Celestial and her family sit down for Thanksgiving dinner and a blackberry jam cake is served as dessert. Described as a recipe that has been passed down through the generations, the cake is supposed to be made on “the last day of summer” so it is ready by the holidays.
This cake sounds bomb, but truthfully we do not feel like waiting months to enjoy An American Marriage themed treat! Instead, we became inspired by the ingredients that Celestial describes like cinnamon, rum, and blackberries and turned them into a simple summertime tart.
For the graham cracker crust:
- 2 3/4 cups graham cracker crumbs
- 1/2 cup melted butter
- 1/4 cup sugar
For the custard filling:
- 2 cups milk
- 2 tablespoons corn starch
- 1/3 cup sugar
- 2 eggs, beaten
- 1 teaspoon vanilla
- 2 tablespoons dark rum
- 1 teaspoon cinnamon
For the topping:
- Fresh blackberries
- 1/2 cup jam
- 2 tablespoons water
- Preheat oven to 350 degrees and grease a 9 inch pie dish
- Make the graham cracker crust by blending the graham crackers, melted butter, and sugar in a food processor
- Bake in the oven for 11 minutes or until golden brown
- As the crust cools, begin making the custard. I used this recipe and added in the rum and cinnamon at the end
- Once the custard is cool, pour into the crust and even out with a rubber spatula. Push the blackberries into the custard and place in the fridge to set (about 2 hours)
- OPTIONAL: In a small bowl whisk together 2 tablespoons of water with 1/2 cup of blackberry jam until it is runny; drizzle on top of the tart for effect!
