Ingredient Breakdown
- Cheerios
- Peanut Butter
- Honey or Maple Syrup
- Vanilla Extract
- Chocolate Chips (Optional)
Let’s Get Cooking!
Step 1: Mix It Up!
In a large bowl, combine the peanut butter, honey (or maple syrup), and vanilla extract. Stir them together until they’re thoroughly mixed, don’t be shy here! You want it all to be smooth and cohesive, with that comforting aroma wafting up. This is about a 2-minute process.
Step 2: Cheerio Time!
Next, add in the Cheerios. Grab a wooden spoon or a spatula and gently fold them into the peanut butter mixture until every piece of cereal is well coated. This will only take a minute or so, but trust me, it’s a workout for your arms! We want every Cheerio lovingly embraced by that yummy peanut butter mixture.
Step 3: Chocolate Chip Surprise!
If you’re feeling decadent, now’s the time to fold in the chocolate chips (if using). Ensure that they’re evenly distributed throughout the mixture, talk about leveling up this snack!
Step 4: Pack It In!
Line a medium-sized baking dish (about 8×8 inches) with parchment paper or lightly grease it. Pour your Cheerio mixture in and press it down evenly with your hands or a spatula. The key here is to pack it in tightly; if it’s loose, your bars may fall apart when you cut them.
Step 5: Chill Out!
Pop the pan in the fridge and let it chill for about 30 minutes. This really helps the bars to firm up and makes slicing them much easier.
Step 6: Cut and Serve!
Once chilled, take those bars out and cut them into squares or rectangles, whatever shape you’re feeling! Serve them up as a snack or a dessert. Your family will be BEGGING for more, guaranteed!
