Preheat oven to 350℉. Prepare your baking pan with a parchment sleeve. This makes it easier to remove the blondies after baking.
In a small bowl, mix the flour, espresso powder, salt, and baking powder. Set aside.
In a 2-Cup liquid measuring cup, cream butter and brown sugar for 1 minute using an immersion blender with a beaters attachment. Add the egg, vanilla, and cream for about 30 seconds.
Add 1/2 of the flour mixture and mix lightly. Add the remaining flour mixture and mix until combined. The dough will be stiff.
Place the stiff dough into the prepared pan. The dough should be slightly elevated in the middle. This helps the blondies to be of an even thickness.
Bake for 20-25 minutes. They should be golden brown, and a toothpick should come out clean, no crumbs.
Remove to a cooling rack for 15 minutes. Remove blondies with the parchment sleeve and cool completely. Cool before covering in chocolate.
Cut the blondies into quarters, then cut each square in half diagonally. Remove any crumbs from the edges.
In a clean 2-cup glass measuring cup, add the almond bark and the 3 tablespoons of chocolate chips. Microwave for 90 seconds. Remove and stir until smooth.
Using a spoon or a knife, spread the chocolate coating evenly over the top and sides of each blondie piece. Add the coffee beans if using. Sprinkle with edible glitter if using.
Place the covered blondies on a cooling rack and place them in a refrigerator for the chocolate to firm up. Enjoy!
