1-First Step: Preheat and Prepare Your Pan Start by preheating your oven to 350 degrees Fahrenheit. This step is crucial for even baking. Line a 9×9 inch baking pan with parchment paper, which makes it easy to remove the bars later and prevents sticking for a clean finish.

2-Second Step: Mix the Wet Ingredients Next, beat together the softened butter and sugar until the mixture is fluffy and light this usually takes about 2-3 minutes with an electric mixer. Add the large egg and vanilla extract, blending until fully incorporated. This creates a smooth base that holds the dough together nicely.

3-Third Step: Incorporate the Dry Ingredients Gradually add the flour and baking powder to the wet mixture, stirring until a thick dough forms. Be careful not to overmix, as this can make the bars tough. Gently stir in the festive sprinkles at the end for even distribution without breaking them apart.

4-Fourth Step: Spread and Bake the Dough Spread the batter evenly in your prepared pan. If the dough feels thick, a pastry roller can help. Bake for 20 minutes or until the top is golden brown. Keep an eye on it to avoid overbaking, which might dry out the bars for more ideas on baking techniques, check out simple scone recipes that use similar methods.

5-Fifth Step: Cool the Bars Remove the pan from the oven and let it cool completely on a wire rack. This step is important for the bars to set properly. Once cool, lift the parchment paper to remove the bar from the pan, making it easier to frost without mess.

6-Sixth Step: Make the Frosting For the frosting, blend the powdered sugar, softened butter, cream cheese, vanilla extract, and milk until smooth. This should take 1-2 minutes of mixing. If you want a thicker frosting, add a bit more powdered sugar; for thinner, add milk a teaspoon at a time.

7-Final Step: Frost, Decorate, and Serve Spread the frosting evenly over the cooled cookie bar and sprinkle on additional sprinkles for a festive look. Cut into squares and serve right away, or let the frosting set for a firmer texture. These bars pair well with other treats, like those found in funfetti muffin recipes for a complete holiday spread. Enjoy the satisfaction of homemade goodies that bring everyone together.
