Healthy Peach Crumb Bars – a delightful balance between indulgence and nourishment. With oats, protein powder and egg white these peach crumble bars are high protein, low fat, and added sugar free!

I had 4 peaches in the last week of summer and too many ideas of what to do with them. Put a poll on my Instagram stories and about 90% of the people voted for these peach crumb oat bars instead of a trifle.

A real good call there; These bars are not only a delicious way to enjoy the bounties of summer but also a guilt-free pleasure that you can savor with every bite.

And super easy to make with simple ingredients!

How to make Healthy High Protein Peach Crumble Bars with Oats

These protein powder peach crumble bars with oats are really easy to make.

Prep peaches: Combine sliced peaches, brown sugar, cinnamon, cornstarch, lemon juice in bowl.
Let rest 3-4 minutes so flavor soaks in.

Combine dry ingredients for the crumble – oats, flour, vanilla and unflavored protein powder, cinnamon.
Use whey-casein protein powder since it works well with the ratio of ingredients here.
If you use a whey protein powder, you might want to reduce the amount of milk to make it less.

Transfer mix into food processor

Add chopped cold butter and blitz few seconds until combined.

Move back to bowl; Add applesauce and egg whites and mix.
Mix the base layer well to form a smooth mixture, but don’t over-mix since the protein powder might make the texture tough.
It should be like a dough.
Taste dough for sweetness; Add powdered sweetener or stevia if needed

Transfer ¾ mix into parchment-lined baking pan.

Spead peaches over base layer.

Add remaining crumble mix on top.

Bake at 350°F for 25 minutes
Cover with foil tent after 18 minutes to prevent top of peach crumble bars from burning.

To store Protein Peach Bars

To store soft baked protein peach oat bars, let them cool, then place in an airtight container and keep in the fridge for up to a 1 week.

To freeze, place healthy peach oatmeal bars in airtight sealed container, or individually wrapped in plastic wrap and placed in zipper bag; Homemade peach oatmeal bars should keep for 2 or 3 months. Be sure to let the peach protein bars thaw on the counter before eating!
