Ingredients

For the Bars

2 cups dry roasted peanuts
2 cups M&M’s

How to Make No Bake Peanut Butter Cereal Bars

Step 1: Prepare Your Pan

Spray a 15” x 10” x 1-inch baking pan with non-stick spray. Make sure it’s evenly coated to prevent sticking.

Step 2: Combine Dry Ingredients

In a large mixing bowl, combine the cheerios, crisp rice cereal, dry roasted peanuts, and M&Ms. Toss them gently until well mixed.

Step 3: Boil Syrup Mixture

In a medium saucepan, bring the light corn syrup and sugar to a boil over medium heat. Stir frequently to avoid burning. Once boiling, remove from heat.

Step 4: Mix in Peanut Butter

Stir in creamy peanut butter and vanilla into the hot syrup mixture until smooth. This will create a rich sauce that binds everything together.

Step 5: Combine Mixtures

Pour the warm syrup mixture over the dry ingredients in your large mixing bowl. Toss everything gently but thoroughly, ensuring all pieces are well-coated.

Step 6: Spread in Pan

Transfer the mixture into your prepared baking pan. Use your rubber spatula to spread it evenly across the surface. Press down gently to compact it.

Step 7: Let Set

Allow your no bake peanut butter cereal bars to cool at room temperature until set. This typically takes about an hour but can be quicker if placed in the fridge.

Once set, cut into squares or rectangles and enjoy!

Common Mistakes to Avoid

When making no bake peanut butter cereal bars, it’s easy to make a few common mistakes. Here are some tips to help you avoid them.

Skipping the non-stick spray: Not spraying your pan can lead to a sticky mess. Always ensure your pan is coated to make removal easier.
Not mixing thoroughly: Failing to coat all the cereal and peanuts evenly can result in uneven texture. Take your time to mix everything well for the best results.
Ignoring measurement accuracy: Incorrectly measuring ingredients can alter the taste and texture. Use measuring cups and spoons for precision.
Rushing the cooling process: Cutting the bars too soon can cause them to crumble. Allow enough time for them to set properly before slicing.
