Heat your oven to 350°F and get your ingredients ready. If your butter feels firm, pop it in the microwave for just 10 seconds to soften it slightly.
02 -
In a large mixing bowl, cream together the softened butter and sugar using a mixer on medium speed for about 30 seconds. Add the egg, vanilla, and almond extract while the mixer is still running.
03 -
Mix in the baking powder and salt, then gradually add the flour half a cup at a time on low speed. Stop mixing as soon as the flour disappears - the dough should feel like playdough when pinched.
04 -
Spray a light-colored 9x13 metal pan with cooking spray, then line it with parchment paper, leaving about 2 inches hanging over the long sides for easy removal.
05 -
Drop tablespoon-sized chunks of dough into the prepared pan, then use your hands or a spatula to press it evenly across the bottom. If it's sticky, place another piece of parchment on top while pressing.
06 -
Bake for 14-16 minutes, removing them as soon as you see the tiniest golden edges. The center might look underdone, but that's perfect - they'll finish cooking as they cool.
07 -
Let the bars cool completely in the pan before frosting. You can speed this up by placing the pan on a cooling rack in the fridge.
08 -
Beat the softened butter in a large bowl for 1-2 minutes until creamy. Gradually add vanilla, almond extract, and powdered sugar, then beat on high for 2 minutes until fluffy.
09 -
Mix in 1-2 tablespoons of milk until the frosting spreads easily. Add green food coloring and mix until you get your desired Christmas tree shade. Spread evenly over the cooled bars.
10 -
Add sprinkles immediately after frosting so they stick properly. Chill the frosted bars for 30-60 minutes before cutting to prevent the frosting from smearing.
11 -
Use a sharp knife to cut the chilled bars into 24 tree-shaped pieces. Clean your knife between cuts for the neatest results.
