Step 1

Preheat oven to 350 degrees.  Prepare an 9x13 inch baking pan by lining it with parchment paper.  Set aside.

Step 2

In a large mixing bowl, pour in the melted butter, add the sugar, and the molasses.  Beat with a hand-held mixer until smooth.

Step 3

Add the egg and beat into the butter and sugar mixture.

Step 4

Add the rest of the flour, baking soda, cinnamon, salt, ginger, and cloves.  Mix into the wet ingredients until just mixed through.

Step 5

Transfer the dough to the baking pan and press the dough into the pan until evenly distributed and flat.

Step 6

Bake for 25 minutes.  Remove from the oven and allow the bars to completely cool.

Step 7

Once cooled, prepare the frosting by by beating together the frosting ingredients with a hand-held mixer until creamy and smooth.

Step 8

Spread evenly over the bars. Top with sprinkles and refrigerate for one hour.

Step 9

Lift the bars out of the baking pan, using the parchment paper to lift.  Transfer to a cutting board.  Cut into 24 squares.

Step 10

Bars can be stored in a food-safe container in the fridge for 5-7 days.  If you want to freeze, do not frost.  Add the frosting after the bars are completely thawed.
