Pinterest recipe review - Pumpkin Bread with Salted Caramel Drizzled Pumpkin butter Cream

This was the most moist, flavorfull any kind of bread I've ever had.  Instead of all of the different spices it called for, I used a tablespoon of pumpkin pie spice (which, of course is all of those spices together).  I did mess up on the frosting because I'm thinking I used too much butter, but the bread itself is good enough without it.  I found the recipe on Pinterest and here: http://jujugoodnews.com/pumpkin-bread-with-salted-caramel-drizzled-pumpkin-butter-cream/#
Here it is:

Ingredients

For the Bread
1 C all-purpose flour
3/4 C white whole wheat flour
1 1/2 tsp cinnamon
1/2 tsp nutmeg
1/2 tsp allspice
1/8 tsp cloves
1/2 tsp salt
1 tsp baking soda
1 tsp baking powder
2 eggs
3/4 C brown sugar
1/4 C granulated sugar substitute
1 tsp vanilla extract
1/2 C low-fat plain yogurt
2 tbsp canola oil
1 1/4 C pumpkin puree

For the Frosting
1/4 C butter, softened
2 tbsp pumpkin puree
1/2 tsp cinnamon
1/2 tsp vanilla
1 1/2 C confectioner’s sugar, sifted
2 tsp milk
For the Caramel Drizzle
3 tbsp brown sugar
1 tbsp water
1 tbsp butter
1/4 tsp salt

Directions

1. Preheat oven 325. Grease and flour a 9×5 loaf pan.

2. Whisk together flours, cinnamon, nutmeg, allspice, cloves, salt, baking soda, and baking powder until well-combined. Set aside.

3. In a separate bowl, using an electric or stand mixer, beat eggs until creamy. Beat in brown sugar and sugar substitute on medium speed for one minute. Add in vanilla, yogurt and oil. Beat until well-combined.

4. Add flour mixture and pumpkin, beat until just combined. Scraping down the sides of the bowl as necessary.

5. Spread batter into prepared loaf pan. Bake for 35-45 minutes or until toothpick inserted into the center comes out clean. Allow bread to cool in pan for 10 minutes before removing it to cool completely on a wire rack.

6. While bread is cooling, begin preparing the frosting. Cream together butter and pumpkin puree. Add in cinnamon and vanilla and beat until creamy. Slowly add confectioner’s sugar and milk. Beat until well-combined and creamy. Spread frosting over the top of the cooled bread.

7. In a small saucepan, stir together brown sugar and water. Dissolve sugar over medium-high heat.

8. Continue heating until caramel turns dark brown and starts to boil, making sure to stir constantly to avoid burning. Add butter and salt. Stir to combine and remove from heat. Continue stirring for another 1-2 minutes to cool the caramel somewhat before drizzling over the top of the frosting.

9. Slice bread and serve! Store leftovers in the refrigerator.
