Starbucks Oat Fudge Bars (Copycat Recipe)

An indulgent crumbly, buttery, oatmeal bar made even more luxurious with a thick middle layer of chocolatey fudge! Absolute deliciousness with every bite! Can be made completely gluten-free.

My dear hubby is on a gluten-free diet. He’s been doing this for a long time now because he feels much better with it. He’s not really allergic to wheat, as such, but is gluten-intolerant so when he eats too much of it, he feels lethargic and just not 100% efficient!

Because of this, I try my best to make some gluten-free desserts for him. I feel guilty when he cannot enjoy most of the cakes I make (no matter how scrumptious) because of his low tolerance for anything with flour in it.

Thankfully, I manage to make this gluten-free version of our favorite Starbucks oat fudge bars! The best part is it is equally scrumptious as the all-flour version.

How do you make the Starbucks Oat Fudge Bars gluten-free?

I simply replace the all-purpose flour called for in the recipe with a gluten-free flour mix from Bob’s Red Mill. You can also use your favorite brand of gluten-free flour mix with this.

If you are not allergic to gluten or gluten-intolerant feel free to use your favorite brand of all-purpose flour. I’m just glad that I can make a yummy chocolate-flavored dessert that is perfectly suited to his dietary needs.

While researching the web on how to make this copycat recipe for Starbucks oat fudge bars, I read that these scrumptious bars have been discontinued. I am not 100% sure about this but hey, I’m no longer bothered if it is true because I know I can make a delicious version of it at home!

I know they are delicious because I served these yummy bars at a gathering in our place and got great feedback on them. Some even had second helpings! I admit I did too.

Since an entire 9×13 pan makes about 24 bars, it’s great to serve in a party setting or when you have to entertain a crowd! Because they’re luxuriously rich, you don’t need to slice them into huge pieces!

Can you freeze these Starbucks Oat Fudge Bars?

Yes, you can certainly freeze these. If you have any leftovers or wish to just take out one bar at a time, I suggest cutting them first into individual bars then placing them in a freezer-friendly container separating them each with a layer of parchment paper. That would make it easier to separate them later.

Notes

TIPS & TRICKS
If using, unsalted butter, add about 1/2 teaspoon salt to the oatmeal mixture. This would not only enhance the taste it would help cut the overall richness of the fudge bars. 
Completely cool the Starbucks Oat Fudge Bars before slicing. Preferably, chill it in the fridge before serving so it would be easier to cut up. Because the chocolate filling is quite fudgy – it won’t dry up when chilled.

    I’m a little confused with the recipe/steps.
    How much of the butter do you cream with the eggs and sugar and how much of the butter do you heat in the saucepan?

      I’ve made these several times, I love them best when they are cold. I’ve replaced half the butter in the dough for peanut butter on one occasion. That was yummy! These go over very well for bake sales.
      You can cut the recipe in half and bake them in a 9” pan for about 20 minutes

    I have NEVER commented on a recipe before now but the world needs to know that these are incredible and a near perfect substitute. I have missed those Starbucks oat fudge bars so much but now can make an entire batch for the price of just one! Thank you for sharing this!

      Hi Jane! I don’t have a conversion table here but if you try to go online and google it – it should be very easy to find. Thank you and honestly, this is so delicious it would be worth all the effort! Thank you.

    I was wondering if I could substitute peanut butter for half the butter? Could I also halve the recipe and make it in a 9” square pan?

    How soon in advance can these be made for an event? They’re amazing, and every time I make them I serve them the following day. Could I make them 2 days in advance and keep them refrigerated? I have a lot of dishes to make for a baby shower and if I could get these done a day earlier, it’ll help me save time since I have dishes that can only be made the night before, or “day of”.

      Yes, I don’t think that should be a problem. Just keep them in an airtight container in the fridge.
