                       <p>Get ready to unleash your inner baker with this colossal cookie cake adventure!  It&#8217;s a giant, gooey, chocolatey explosion of flavor that&#8217;s guaranteed to satisfy even the most insatiable sweet tooth. <img src='https://www.southernkissed.com/wp-content/uploads/2022/04/Cookie-cake-decorated.jpeg'></p>
<p>First things first, preheat your oven to 350°F (175°C).  While the oven is warming up, grab a 9-inch round cake pan and line it with parchment paper.  Give that parchment paper a good spritz of cooking spray – this is crucial for preventing a sticky situation and ensuring those edges get perfectly golden brown. Think of it as a superhero cape for your cookie cake, protecting it from sticking!</p>
<p>Now, for the fun part! In a big bowl, whip together the softened butter and sugars until the mixture is light and fluffy.  Think clouds of sugary goodness! Add the egg and beat until everything is happily mingling. Stir in that vanilla extract – a dash of magic to enhance the flavor. </p>

<p>Next, gently fold in the flour, baking soda, and salt. Don&#8217;t overmix; we want to keep things light and airy. Once the dry ingredients are just combined, it&#8217;s time for the star of the show: chocolate chips!  Add those delicious morsels and a rainbow sprinkle explosion, folding them in until they&#8217;re evenly distributed. Imagine a galaxy of chocolate and sprinkles swirling together!</p>
<p>Carefully transfer your magnificent cookie dough into the prepared cake pan. Gently press it down into an even layer, creating a perfect canvas for your culinary masterpiece. Feeling extra generous? Sprinkle even more chocolate chips and sprinkles on top.  Why not, right?  More is more!</p>

<p>Slide your cookie cake into the preheated oven and bake for 25-30 minutes, or until it&#8217;s golden brown and smells heavenly.  Keep an eye on it; you don&#8217;t want to burn your masterpiece. Once baked, let it cool in the pan for 15 minutes before transferring it to a cooling rack to cool completely. Patience, young padawan!</p>
<p>Once completely cool, it&#8217;s frosting time!  Whether you&#8217;re using store-bought or homemade frosting,  pipe or spread it around the edges of your cookie cake. Get creative!  A star tip creates beautiful swirls, but you can also use a simple ziplock bag with a corner snipped off. Sprinkles are your friend, so don’t be shy! <img src='https://www.designeatrepeat.com/wp-content/uploads/2022/06/cookie-cake-icing.jpg'></p>
<p>Slice and serve! This cookie cake is best enjoyed fresh, but leftovers can be stored, covered, at room temperature for a few days.  But let’s be honest, leftovers are a rare sight with this irresistible treat.
