How to make oatmeal fudge bars
Full recipe is in the recipe card at the bottom of the post!
Equipment
- Mixing bowl
- Loaf pan
Ingredients & substitutions
- Oats: I like to use organic quick oats as the bars tend to hold together better with the smaller flakes, however old fashioned rolled oats will also work! Note: If you don’t have quick oats, you can always pulse rolled oats in a food processor for a second or two to break them down a little!
- Peanut butter: You can sub any nut or seed butter. Sunflower seed butter makes a great nut-free option!
- Chocolate chips: I like to use the brand Hu Kitchen to keep these refined sugar free. I have a code “danishealthyeats” for a discount!
- Maple syrup: You can also use honey or another sticky sweetener.
- Vanilla extract & sea salt

Steps to make peanut butter oatmeal fudge bars
- Mix together the oat base ingredients until a sticky-ish mixture forms.
- Press half of the mixture into the bottom of a lined loaf pan.
- In a large bowl, add the peanut butter filling ingredients. Heat in 30 second increments, stirring well between each, until smooth. Pour the mixture over the oat base.
- Sprinkle the remaining oat mixture over top of the filling, pressing it gently into the top.
- Place the pan in the freezer for 3-4 hours before cutting into bars.
how to store leftover oatmeal fudge bars
Store leftovers in an air-tight container in the freezer! You can let them thaw for a few minutes before enjoying for a softer texture, but don’t leave them out for too long as they’ll start to melt.

Third time making…delish and super easy to make 🤩
Love to make, but what size loaf pan?
Do you have the nutritional breakdown or MACRO breakdown for these oatmeal No bake bars?
Hi Bonnie! So I don’t include Macro breakdowns just to be mindful of those who may deal with a disordered relationship with food (as i did for many years). Also because different brands can vary so much. I always recommend people throw the recipe into my fitness pal with the exact brands they use for the most accurate numbers! x
Another great recipe! I like the taste of these waaaay better than the ones they sell at Starbucks. Thank you Dani!
Dani does it again! I made these for some family this Christmas.. and then again for myself because they are so stinkin’ delicious. My Mom came running up the stairs “are they ready yet?!” Lol SO YUM.
Gosh Dani these are so good! I brought HU brand SIMPLE MILK chocolate bars to get the cup of melted chocolate because I guess I overlooked semi sweet chocolate chips. By the time I figured it out I was already in the middle of making them! The salt made it taste like they had butter in them! I cut them into 16 bars to get the calorie count down but I’m not phased because the ingredients are so good and my tummy doesn’t hurt after eating them at 11 at night!
Hi Crystal! Omg, that Hu chocolate is my weakness – so good! I’m so happy you (and your tum) love them! Thank you for trying them! (:
I don’t have gf quick oats. Can I use regular gf oats & give them a blast in my Vitamix? Obsessed w all of your recipes!
