Preheat the oven to 375°F. Line a 9x13 baking dish with parchment paper and spray with baking spray, set aside.
Add the flour, baking powder, baking soda, and salt to a large bowl and whisk until combined, set aside.
In the body of a stand mixer with the paddle attachment or with a hand mixer and a large bowl, cream together the butter and sugar until light and fluffy, about 3 minutes.
Add the eggs one at a time until incorporated. Add in the vanilla and almond extracts, mix until combined.
Add the flour mixture a little at a time to the wet ingredients and mix in until just combined, with no dry patches, but do not overmix. Scrape down the sides as needed.
Add the sprinkles and stir until just incorporated.
Press the cookie dough into the bottom of the prepared baking dish. Bake for 20-24 minutes until lightly golden brown along the edges and a toothpick inserted into the center comes out mostly clean. Let cool completely on a wire rack.
While the cookie bar cools, make the frosting. Place the butter in the body of a stand mixer with the paddle attachment or in a large bowl with a hand mixer and whip the butter until smooth.
Add the powdered sugar a little at a time and mix until combined.
Add in the cream of coconut, vanilla, coconut extract, and salt, and stir in until combined. Scrape the sides as needed.
Whip on medium-high speed for 3 minutes until fluffy.
Take the cookie bars out of the baking dish, you can use the parchment paper to help. Evenly spread the frosting on top of the bars.
In a gallon-sized zip-topped bag, add the coconut flakes and a couple of drops of green food coloring. Close the bag and toss around until the coconut is dyed green, add more food coloring if needed to reach your desired shade.
It is easier to serve if you cut the bars first and then sprinkle the dyed coconut on top.
Add an Easter peep to each slice and jelly beans, and serve immediately.
