These homemade chocolate revel bars are basically gooey oatmeal cookies swimming in a sea of hot fudge, on top of a soft and chewy oatmeal cookie base. I know. I know! They are incredible. Also known as oatmeal fudge bars or oatmeal cookie bars, they are a fabulous dessert. These are my go-to treat to bring to a dinner or party or dinner party and they are ALWAYS a hit!
These are rich and delicious. So fudgy, so gooey, so chocolatey.

Below is a list of ingredients needed for this recipe. Follow our tips on each ingredient for best results.
For the cookie base:
- butter - I use salted. If you use unsalted, be sure to add ¼ teaspoon extra salt.
- brown sugar- light or dark. Sometimes I use dark for a richer more caramel-y taste. We have recipe tested it and most taste testers preferred them when we made them with half light and half dark.
- vanilla- pure vanilla gives the best flavor!
- baking soda
- salt- basic table salt
- all-purpose flour
- rolled oats- I prefer mine with old fashioned, but quick oats work great too! We have tested this recipe many times and found that those who like a nice oatmeal texture preferred old fashioned oats.
For the fudge sauce:
- butter - Again, I used salted. There is a minimal amount of butter, so if you use unsalted, don't worry about adding more.
- sweetened condensed milk
- chocolate chips - I always use semi sweet for this recipe. We found when we tested the recipe with milk chocolate chips it was just too sweet when combined with the sweetened condensed milk.
- vanilla - Again, use pure for the best flavor.
How to Make Oatmeal Fudge Bars
Use these process shots to help get the results you are wanting. The pictures can help with texture and be a visual guide for best results.
1. Preheat oven to 350*F. Cream together butter and sugar in a large mixing bowl with a hand mixer or in the bowl of a stand mixer. Mix about 2 minutes until it has lightened and is fluffier looking.
2. Add eggs and vanilla. Cream on high speed about 1 minute until the mixture has lightened and is fluffy looking. Don't skip the creaming step- it helps the texture of the finished product.
3. Add the flour, baking soda and salt. Mix on low/ medium-low speed until slightly under combined. Add oats then mix just until combined. Try not to over mix on this step.
4. In a saucepan heat butter, sweetened condensed milk, chocolate chips and salt. Heat over medium low heat until melted and smooth. Stir regularly to keep it from scalding to the bottom of the pan. Once it all melts together and becomes smooth, remove from heat and stir in vanilla.
5. Press about ⅔ of the oatmeal cookie base into the bottom of a 9x13 pan. Pour all of the hot fudge mixture over the top.
6. Using your hands, press the remaining dough into pieces of different shapes and sizes and place on top of the fudge- the thickness should be uniform. Place on top of the fudge. Bake for 25 minutes.
They are finished when the cookies are matte and a toothpick comes out clean. Don't worry about fudge on the toothpick, it's cookie dough you need to worry about here. Sometimes we like to slightly under bake them for an extra gooey texture. Enjoy and revel in your chocolate revel bars!!
Hint: Do not over bake these! You'll miss out on the soft gooey texture and be met instead with dry crumbly bars.

Substitutions and Variations
We love switching things up when we're in the kitchen. Try any of these variations for something a little different.
- oat-free- make these oat free by not adding the oats. My son has a sensitivity to oats, so sometimes I make these oat free for him. Use an extra ½ cup flour
- Oatmeal Chocolate Chip Bars- in a hurry? Skip the fudge sauce and use one package of chocolate chips instead. It's not quite the same, but still a yummy alternative.
- Caramelitas- before adding the fudge, pour a layer of caramel on top of the dough. This can be store bought or try our yummy caramel topping, cooking it until it reaches a full soft ball stage.
Somehow these delicious little delights taste even better the next day! Store in an airtight container at room temperature for up to 3 days for the freshest taste.
Store in an airtight container in the freezer for up to 2 months. Thaw to room temperature.
These are delicious as is and don't need to be reheated in any form.
Do not over bake! The last thing you want to do is take these from soft ooey gooey delights to dry and crumbly boring treats.
Make sure to beat the butter and sugar together the entire time recommended. It will give you the best flavor and texture.
Don't scorch the fudge. Stir it while it's cooking. As soon as it's all melted and combined it's done so remove it from the heat.
Chocolate Revel Bars
For the dough:
- ⅞ cup butter softened (1 cup minus 2 tablespoons butter, to be used in the hot fudge)
- 2 cups dark brown sugar light works fine too, but for that caramel-y taste use dark!
- 2 teaspoons vanilla
- 2 eggs
- 1 teaspoon baking soda
- ½ teaspoon salt
- 2 ½ cups flour
- 3 cups rolled oats I use old fashioned but quick work too
For the hot fudge:
- 14 ounce sweetened condensed milk
- 12 ounce semi sweet chocolate chips
- 2 Tablespoons butter
- 2 teaspoons vanilla
- ½ teaspoon salt
- Preheat oven to 350* F.
- Using a stand mixer or mixing bowl and hand mixer, beat softened butter and sugar together until light and fluffy, about 3 minutes.
- Add vanilla and eggs and mix on high about 1 more minute until the mixture lightens and is fluffier.
- Add baking soda, salt and flour and mix until just combined. I like to put the flour in first, then put the salt and baking soda on top then mix it lightly with my fingertips so that the salt and soda get incorporated throughout.
- Add the oats and mix until just combined. Be careful not to over mix!
- Press ⅔ of the dough onto the bottom of a 9x13 pan.
- Make the hot fudge sauce. Combine all ingredients in a saucepan and heat over medium low heat stirring occasionally until the sauce is smooth.
- Pour hot fudge sauce on top of dough in pan
- Using your hands, grab chunks of the dough and smash into different sized cookies (keeping the thickness the same) and place on top of the fudge at random. Press the dough very slightly into the fudge.
- Bake for 20-25 minutes, until the top of the bars turn matte and an inserted toothpick comes out without cookie dough on it. Don't worry if there is a little fudge on the toothpick.
These are so heavenly and enjoyable, and the word revel means: 'enjoy oneself in a lively way' and that's exactly what you'll do while enjoying these!
Absolutely. Store in an airtight container for up to 2 months. Thaw to room temperature and enjoy! No need to reheat.
