Thought my nana’s recipe was gone forever. Found it, and it’s even more delicious

Ingredients:

4 eggs
1/2 cup shortening
1 1/2 cups granulated sugar
2 teaspoons vanilla extract
1 cup buttermilk
1 tablespoon baking powder
2 cups all-purpose flour
1/2 teaspoon salt

For the filling:
1/2 cup brown sugar
4 teaspoons ground cinnamon

For the glaze:
2 cups powdered sugar
1/4 cup milk
3 tablespoons unsalted butter
1 teaspoon vanilla extract

Instructions:

1. Preheat the oven to 350°F (175°C). Grease a 9×13 baking dish.

2. In a mixing bowl, cream together shortening and granulated sugar until smooth. Add eggs one at a time, beating well after each addition. Stir in buttermilk and vanilla extract.

3. Gradually add all-purpose flour, baking powder, and salt. Mix until just combined.

4. Pour half of the batter into the prepared pan.

5. In a separate bowl, mix brown sugar and ground cinnamon for the filling. Sprinkle this mixture evenly over the batter in the pan.

6. Carefully spread the remaining batter over the cinnamon filling.

7. Use a knife to gently swirl the batter and filling together, creating a marbled effect.

8. Bake in the preheated oven for 30 minutes, or until a toothpick inserted into the center comes out clean.

9.. While the cake is baking, prepare the icing. In a saucepan, melt the unsalted butter over low heat. Stir in powdered sugar, milk, and vanilla extract until the icing is smooth.

10. When the cake is done baking, remove it from the oven and poke holes all over the top. Drizzle the icing over the warm cake, spreading it evenly.

11. Allow the cake to cool slightly before serving. Cut into slices and enjoy your delicious Cinnamon Roll Cake!
