Step 1

Add yeast to 1 cup of lukewarm water. Stir with a spoon and set aside for about five minutes.

Step 2

In the bowl of a stand mixer, add shortening, sugar, and salt to hot water and beat for 30 seconds. Let cool to lukewarm temperature. Stir in 2 cups of flour and mix until smooth. Add yeast mixture and mix until well combined. Mix in the beaten eggs.

Step 3

Gradually stir in the remaining flour and mix with the dough hook for about 2 minutes. Remove dough from the bowl and place on a lightly floured counter. Knead by hand, add a little flour if the dough is still sticky. Knead until dough feels satiny and smooth.

Step 4

Put the dough in a greased bowl and cover with a towel. Let rise for 30 minutes or until dough doubles in size.

Step 5

Remove dough from bowl and place on a lightly floured counter. Divide dough in half. With a rolling pin, roll one half of the dough into a rectangular shape. Spread dough evenly with 4 tablespoons of softened butter. Sprinkle dough with 1/4 cup brown sugar. In a medium bowl, carefully stir together the raspberries, granulated sugar, lemon zest, and cornstarch. Sprinkle half of the raspberry mixture over the dough.

Step 6

Gently roll up dough into one long roll. Cut rolls, using a piece of dental floss or thread, about two inches thick. Place rolls into a greased 9X13 baking pan.

Step 7

Now follow the exact same steps with the other half of the dough, using the remaining ingredients.

Step 8

Place rolls in a warm spot and cover with a towel. Let rolls rise until double in bulk, about an hour. Bake rolls at 350 degrees F for 25-32 minutes or until golden brown on top. The insides should be soft, but not doughy. Remove pans from oven and let cool on a wire rack.

Step 9

While the rolls are cooling, make the frosting. In a medium bowl, combine cream cheese, butter, powdered sugar, and lemon zest. Using electric mixer, beat until smooth. Spread frosting on rolls and serve.
