Funfetti Ooey Gooey Bars are an easy dessert bar inspired by the classic birthday cake. Every bite of these buttery soft bars is packed with sweet vanilla flavor and plenty of sprinkles!
Line an 8” x 8” baking pan with parchment paper. Leave the sides a little higher than the pan so the bars can be lifted out easily after they’ve cooled. Spray the parchment paper lined pan with non-stick cooking spray and set aside.
In a large bowl, beat together the dry cake mix, butter, egg and vanilla extract until fully combined (about 30 seconds). Do not over mix.
Stir in the sprinkles and white chocolate chips.
Press about 2/3 of the dough mixture into the bottom of the prepared pan. This dough will be thick (cookie dough consistency). If you are having difficulty spreading dough into the pan, lightly spray a spatula with non-stick cooking spray to help spread out the bottom layer.
Spread the sweetened condensed milk evenly over the first dough layer.
Press the remaining 1/3 of dough into super flat pieces and cover as much of the sweetened condensed milk layer with the dough as possible.
Place baking tray in oven and bake for 29 to 31 minutes – the middle will look set and edges will be slightly browned. Do not over bake or these bars will lose the gooey texture.
Let ooey gooey bars cool in pan for at least 60 minutes before removing from pan and slicing into 16 squares. For clean edged squares, wipe the knife with a damp cloth in between cutting each row.
Store ooey gooey bars in a sealed food safe storage container at room temperature for up to 3 days or in fridge up to a week.
