Method: No Bake Peanut Butter Cheerio Bars
Step 1: Prepare Your Baking Dish
Start by preparing your 9×13 inch baking dish. To prevent the bars from sticking, either spray it with non-stick spray or line it with parchment paper, leaving some overhang for easy removal later.
Step 2: Combine Sugar and Corn Syrup
In a large saucepan over medium heat, combine the 1 cup of white sugar and 1 cup of light corn syrup. Stir continuously until the mixture comes to a boil. Once boiling, let it cook for an additional 1-2 minutes without stirring.
Step 3: Add Peanut Butter and Vanilla
Remove the saucepan from heat and stir in 1 cup of peanut butter and 2 teaspoons of vanilla. Mix until completely smooth and well combined. The warm mixture will make it easier to incorporate the peanut butter.
Step 4: Mix in Cheerios and Peanuts
In a large mixing bowl, add the 6 cups of Cheerios and 1 cup of chopped peanuts. Pour the warm peanut butter mixture over the cereal and nuts. Using a spatula, gently fold everything together until the Cheerios are fully coated.
Step 5: Press the Mixture into the Dish
Transfer the mixture into your prepared baking dish. Use the spatula to press it down firmly into an even layer. This step is crucial to ensure the bars hold their shape once set.
Step 6: Let Them Set
Allow the bars to cool at room temperature for about 1-2 hours. For quicker results, you can place them in the refrigerator to set. Once firm, lift the bars out of the dish using the parchment paper overhang and cut into squares or rectangles.
What to Use Instead
- Honey – For a natural sweetener, use honey instead of corn syrup.
- Almond butter – Substitute peanut butter with almond butter for a different flavor.
- Gluten-free Cheerios – For a gluten-free option, ensure you use certified gluten-free Cheerios.
- Chocolate chips – Add mini chocolate chips for a sweeter twist.
Troubles You Can Avoid
- Make sure to boil the sugar and corn syrup mixture for just the right amount of time; too long can make the bars hard, while too short may prevent them from holding together.
- Ensure you mix the peanut butter in thoroughly while the mixture is still warm for a smooth consistency.
- Press the mixture firmly into the baking dish to avoid crumbly bars.
- Allow enough time for the bars to set before cutting into them; patience pays off!
Storage Pro Tips
To keep your No Bake Peanut Butter Cheerio Bars fresh, store them in an airtight container at room temperature for up to one week. If you want to keep them for longer, they can be refrigerated for up to two weeks. For longer storage, consider freezing the bars. Just wrap them individually in plastic wrap and place them in a freezer-safe bag. They’ll stay fresh and delicious for up to three months!
Questions People Ask
Can I use another type of cereal?
Absolutely! While Cheerios are the classic choice, you can use any similar cereal, such as Rice Krispies or Cornflakes, for a different texture and flavor.
How do I make these bars vegan?
To make these bars vegan, substitute the honey with maple syrup and use a vegan-friendly peanut butter. Ensure the cereals and any add-ins are also vegan-friendly.
Can I add chocolate to these bars?
Yes! You can fold in mini chocolate chips into the mixture before pressing it into the pan, or drizzle melted chocolate over the top for an extra treat.
Why are my bars falling apart?
If your bars are crumbly, it may be due to insufficient binding from the sugar and corn syrup mixture. Make sure to boil the mixture long enough and press the mixture firmly into the baking dish.
