what are 4 ingredient oatmeal cookies

Four ingredient oatmeal cookies are healthy “cookies” made with just mashed-up banana, peanut butter, and oats with some chocolate chips thrown in for good measure.

how to make 4ingredient oatmeal cookies

These cookies are naturally sweet and have a great texture – it’s almost like a bowl of oatmeal in cookie form! I love eating these cookies for breakfast on the go, crumbled over yogurt, or even as a mid-day snack.

a note on Ingredients

• Ripe bananas – You want very ripe bananas, like the ones you’d use for banana bread. Use my method below for quickly ripening bananas if you don’t have any that are ripe yet.
• Natural peanut butter – Use the really drippy kind – not the chunky stuff at the bottom. You can use crunchy if you want but you might need to use more to get the right consistency.
• Old fashioned rolled oats – Don’t use steel cut – quick oats should work though, too.
• Chocolate chips – These are really up to you! Any kind of chocolate chips work, even raisins or nuts would be a great option.

Instructions with pictures

• Prep your baking sheet and preheat the oven to 350F.
• Mash the bananas and mix with peanut butter. Then add oats and chocolate chips.

• Shape the cookies and place on baking sheet.

• Bake for 8 minutes.

how to store 4 ingredient oatmeal cookies

These cookies are best right after baking but can be stored in the refrigerator for up to 5 days in an air-tight container. I highly recommend heating them up slightly for best results.

*do not store at room temperature.

4 ingredient oatmeal cookies Tips

1. Ripe bananas – If your bananas are underripe they will be to chunky to bind together the oats.
2. Shaping – Do be sure to shape your cookies exactly how you want them to look before placing them on the baking sheet.
3. Drippy peanut butter – If you use the chunky peanut butter at the bottom of the natural peanut butter jar, it wont bind the cookies adequately.

how to quickly ripen bananas

Paper bag

Time: 1-3 days

If you have a few days before making this recipe, just take the underripe bananas and place them in a paper bag, and set them on top of the fridge, or somewhere warm. Check every day to see if brown spots have formed (a sign of being baking ripe).

Bake

Time: 30-60 minutes

Preheat your oven to 300F and prep a baking sheet with parchment paper. Place your bananas (peel on) on the baking sheet and heat in the oven checking every 15 minutes. Bake until the peels are completely black.

Microwave

Time: 2-3 minutes

Poke holes in the peel of the bananas, then place on a microwave-safe dish and microwave for 30-second increments until they’re very soft.

Serving Suggestions

• Crumbled overtop yogurt
• Breakfast on the go
• Mid-day snack
