Let’s dive into the process of making these delightful bars. As you follow along, imagine the warm, inviting aromas filling your kitchen, much like they did in my own childhood home.

1. Preheat your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper, leaving some overhang for easy removal.
2. In a large mixing bowl, cream together the softened butter and granulated sugar until light and fluffy. This should take about 2-3 minutes.
3. Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract, embracing the sweet aroma that fills the air.
4. In a separate bowl, whisk together the flour, baking powder, and salt. Gradually add this to the wet ingredients, mixing until just combined. Be careful not to overmix, as we want to keep our bars tender.
5. Gently fold in the rainbow sprinkles, ensuring they’re evenly distributed for that signature Funfetti look.
6. Spread the dough evenly into the prepared baking pan, smoothing the top with a spatula.
7. Bake for 20-25 minutes, or until the edges are lightly golden and a toothpick inserted into the center comes out clean.
8. Allow the bars to cool in the pan for 10 minutes before lifting them out using the parchment paper overhang. Transfer to a wire rack to cool completely before slicing into bars.

As you take your first bite, I hope these bars bring a sense of joy and nostalgia, just as they do for my family and me.
