Mix the cereal and oats together in a bowl and set aside.
Heat the SunButter and maple syrup together in a saucepan on a low flame; stir together until smooth. Or, using a microwave-safe bowl, melt together in 30 second increments, stirring and repeating until smooth.
Remove from heat and stir in the vanilla.
Stir in the instant dry milk.
Pour the SunButter mixture over the cereal and oats mixture and coat well.
If you have a cereal bar mold, take about ¼ cup of mixture and press into each cavity until all are filled. If you don’t have a mold, press the mixture into a 9x13 pan.
Melt the semi-sweet chocolate chips. Drizzle over the bars.
Allow cereal bars to firm up in the refrigerator for about 30 minutes.
Once the cereal bars are set, remove from each cavity in the mold or from your baking pan. Cut into rectangles if you used a baking pan.
Individually wrap each bar and store in the refrigerator for a quick grab-and-go breakfast.
