Optional Enhancements

Step‑by‑Step Instructions for Quick and Easy 3-Ingredient Cereal Bars

Step 1: Prepare the Pan
Begin by lining an 8-inch square pan with wax or parchment paper, allowing some overhang for easy removal later. If you’re making a larger batch, double the recipe and use a 9×13-inch pan. This step is crucial for ensuring your homemade cereal bars don’t stick and are easy to slice when set.

Step 2: Warm the Nut Butter
If your nut butter is too thick to stir easily, gently warm it in a microwave-safe bowl for about 20-30 seconds until it’s soft and easily spreadable. This simple step makes combining with the other ingredients seamless, allowing the flavors to blend beautifully into the cereal bars.

Step 3: Mix Ingredients
In a large mixing bowl, combine your cereal, warmed nut butter, and your choice of sweetener. Stir everything together until fully incorporated; the mixture should be sticky and hold together well. This is the foundation of your cereal bars, so ensure there are no dry patches left in the mixture for an even consistency.

Step 4: Press into the Pan
Pour the mixture into your prepared pan, using a spatula or a piece of parchment paper to evenly spread it out. Press down firmly, ensuring the mixture is compact and level. This pressure will help your cereal bars hold their shape once cut. Aim for a smooth top to make slicing easier later on.

Step 5: Chill to Set
Place the pan in the freezer for about 30 minutes, allowing the cereal bars to firm up completely. This chilling time is essential for achieving that perfect chewy texture, making slicing much easier once you take them out. Keep an eye on them, as you want them to be set but not overly frozen.

Step 6: Slice and Store
Once firm, remove the cereal bars from the pan using the overhang of parchment paper. Place them on a cutting board and slice into bars of your desired size. Store any leftovers in an airtight container at room temperature for a couple of days, or refrigerate for a week. For longer storage, consider freezing them.

Make Ahead Options

These Quick and Easy 3-Ingredient Cereal Bars are perfect for busy weeknights! You can prepare the mixture up to 24 hours in advance—simply follow the initial steps of mixing your cereal, nut butter, and sweetener, then press it into the pan. Once pressed, cover the pan with plastic wrap and refrigerate. The key to maintaining their chewy texture is to make sure they are well-pressed into the pan, preventing crumbling later on. When you’re ready to enjoy these delightful bars, just slice them into portions after chilling for at least 30 minutes in the freezer. With this make-ahead option, you’ll have delicious, homemade snacks on hand whenever you need them!

Tips for the Best Cereal Bars
