Prepare a 9x13-inch baking pan by spraying with nonstick cooking spray and then lining it with parchment paper. * You could also just spray the pan, but I like to add the parchment paper because it makes lifting the treats out easy to cut.
In a large saucepan or pot, over low heat, melt the butter.
6 tablespoons butter
Once melted, add the two bags of mini marshmallows and stir constantly until smooth and entirely melted. Do not increase the heat! Low and slow is what you want.
2 bags (10 oz each) mini marshmallows
Remove the pan from the heat and stir in the cake batter extract.
1 teaspoon cake batter extract
Add in the Rice Krispies cereal and the rainbow sprinkles, and gently stir everything together until the cereal is evenly coated.* Be very careful not to overmix, or to stir too aggressively, as the treats could lose their light and airy texture.
9 cups Rice Krispies cereal, ½ cup rainbow 'jimmies' sprinkles
Dump the mixture into the prepared pan, and use a buttered spatula or wax paper, to gently press the mixture into the pan in an even layer.* You want to press down enough to create a thick, even layer but don't press too hard as that can make the treats drier and crispier. Gentle creates light & fluffy treats.
Place the almond bark in a microwave-safe bowl. Microwave in 30-second intervals, stirring after each one, until completely melted and smooth. Place the melted almond bark into a Ziploc bag with a tiny corner snipped. Drizzle it over the top of the treats in long lines, zig-zags, or any pattern you would like. Immediately sprinkle some additional sprinkles on top of the wet chocolate.

Let the treats cool completely at room temperature and until the almond bark sets, about 20-30 minutes, then use a sharp knife to cut into squares. Enjoy!
Notes
Cake batter extract adds a fun, sweet flavor similar to birthday cake which matches the funfetti theme. If you prefer not to use, you can use vanilla extract instead OR use half vanilla extract + half cake batter extract (I do this and love it, not as much cake batter sweetness but still subtle).
White almond bark is best to use because it melts easily and harden nicely and quickly for a smooth drizzle that holds its shape.
Swap out the rainbow sprinkles for any holiday or celebration!
Use rainbow 'jimmie' sprinkles which are the longer, line shaped sprinkles. The little ball shaped sprinkles (called 'non-pareils') bleed color into the marshmallow mixture, so I don't suggest adding them in with the marshmallows. You can decorate the tops of the treats with the little ball 'non-pareil' sprinkles (I do this because I prefer the look of the little ball sprinkles better).
I like to spray the pan with cooking spray and then lay parchment paper in it, making sure to leave some overhang on the sides. Doing it this way helps the parchment paper stay in place and the overhang makes it easy to lift the treats out and cut into even squares for serving.
