3-Ingredient No-Bake Peanut Butter Oat Squares

Get ready for the easiest, most satisfying treat you’ll make all week! These no-bake peanut butter oat squares combine three simple pantry staples into pure snacking magic. They’re perfectly chewy, naturally sweetened, and absolutely irresistible.

The best part? These squares hit that perfect balance of healthy-ish and indulgent. The natural peanut butter provides protein and healthy fats, while the oats deliver filling fiber. But trust me, they taste so good, no one will believe they’re actually nutritious!

Ingredients

• 1 cup creamy peanut butter
• 1/2 cup honey
• 2 3/4 cups rolled oats

Instructions

1. Line an 8×8 inch baking pan with foil, making sure to leave some overhang for easy removal. Spray lightly with non-stick cooking spray to prevent sticking.
2. In a medium microwave-safe bowl, combine peanut butter and honey. Microwave in 30-second intervals, stirring between each, until completely smooth and well combined (1-2 minutes total). Alternatively, heat in a saucepan over medium-low heat for 3-4 minutes, stirring constantly to prevent burning.
3. Add the rolled oats to the warm peanut butter mixture. Stir thoroughly until every oat is well-coated. The mixture should be thick but still stirrable – if it seems too dry, add 1-2 tablespoons more peanut butter.
4. Transfer mixture to prepared pan. Using slightly damp hands or the back of a spatula (to prevent sticking), press firmly and evenly into pan. Make sure to really compact the mixture – this is key for squares that hold together.
5. Refrigerate for at least 2 hours or until completely set. Use foil overhang to lift from pan and cut into 20 squares with a sharp knife.

Smart Swaps

• Use almond butter or sunflower seed butter for a peanut-free version
• Substitute maple syrup for honey to make them vegan
• Try quick oats instead of rolled for a finer texture

Make It Diabetes-Friendly

• Replace honey with 1/2 cup sugar-free maple syrup (reduces carbs by 8g per square)
• Use natural peanut butter with no added sugars
• Cut into 24 smaller squares instead of 20 to reduce portion size
• Pair with a protein source to slow sugar absorption

Pro Tips

• For extra flavor, toast the oats in a dry pan for 5 minutes before mixing
• Store in an airtight container in the fridge for up to 1 week
• Freeze for up to 3 months – they’re delicious straight from frozen!
• Let sit at room temperature for 5-10 minutes before serving if frozen
