Step‑by‑Step Instructions for Starbucks Oat Fudge Bars Recipe
Step 1: Preheat and Prepare the Pan
Begin by preheating your oven to 350°F (175°C). While the oven warms, line a 9×13-inch baking pan with parchment paper, leaving some overhang for easy removal later. This setup ensures the Starbucks Oat Fudge Bars will come out perfectly without sticking.
Step 2: Cream the Butter and Sugars
In a large mixing bowl, cream together 1 cup of softened butter with ¾ cup of light brown sugar and ½ cup of white sugar using an electric mixer. Blend on medium speed for about 3-4 minutes until the mixture is light and fluffy. This step creates a wonderful base for your bars, ensuring they’re moist and delicious.
Step 3: Incorporate Eggs and Vanilla
Next, add 2 large eggs and 1 teaspoon of vanilla extract to the creamed mixture. Beat them in on low speed until fully combined, which should take about 1-2 minutes. This step adds richness and enhanced flavor to your Starbucks Oat Fudge Bars, making them truly delightful.
Step 4: Mix in the Dry Ingredients
In another bowl, whisk together 1 ½ cups of all-purpose flour, 1 teaspoon of baking powder, ½ teaspoon of salt, and 2 cups of rolled oats. Gradually mix this dry mixture into the wet ingredients until just combined, about 2-3 minutes. Be careful not to overmix, as you want a chewy texture in your bars.
Step 5: Assemble the Base Layer
Scoop out ⅔ of the oat mixture and press it evenly into the bottom of the prepared pan. Use your hands or a spatula to smooth the layer into the corners, creating a solid foundation for the fudge. This base is essential to support the delightful fudge layer that follows in your Starbucks Oat Fudge Bars.
Step 6: Prepare the Fudge Layer
In a microwave-safe bowl, combine 1 cup of semi-sweet chocolate chips and one 14 oz can of sweetened condensed milk. Microwave in 30-second intervals, stirring in between until smooth and fully melted, which usually takes about 1-2 minutes. This creates a luscious fudge layer that will beautifully complement the oat base.
Step 7: Spread the Fudge Mixture
Pour the melted fudge evenly over the pressed oat base, using a spatula to spread it gently to the edges. Ensure the fudge layer is evenly distributed, as it’s crucial for the balance of flavors in your Starbucks Oat Fudge Bars.
Step 8: Add the Remaining Oat Mixture
Using the remaining oat mixture, drop spoonfuls on top of the fudge layer. This will create a rustic, textured finish. You don’t need to cover the fudge completely; just scatter it evenly to allow some fudge to peek through after baking, enhancing the visual appeal of the bars.
Step 9: Bake to Perfection
Place the pan in your preheated oven and bake for about 45 minutes. The edges should be golden brown while the center remains slightly jiggly. This visual cue indicates that your Starbucks Oat Fudge Bars are perfectly baked, ensuring a fudgy center with a chewy oat crust.
Step 10: Cool and Slice
Once baked, remove the pan from the oven and allow the bars to cool completely in the pan. This cooling process will take about 1-2 hours. Once cool, lift the bars out using the parchment overhang and cut them into neat squares. Your Starbucks Oat Fudge Bars are now ready to enjoy!

Make Ahead Options
These Starbucks Oat Fudge Bars are perfect for meal prep enthusiasts! You can prepare the oat base up to 24 hours in advance by following the first five steps and storing it in the refrigerator. Just ensure to cover it tightly with plastic wrap to maintain freshness. The fudge layer can also be made ahead of time and refrigerated for up to 3 days—just reheat it briefly in the microwave before pouring it onto the base. When you’re ready to bake, simply sprinkle the remaining oat mixture on top and follow the final baking steps as directed. This way, you’ll have delicious, homemade bars ready for any occasion with minimal effort!

Starbucks Oat Fudge Bars Recipe FAQs
How do I choose the right oats for my bars?
To achieve the best texture in your Starbucks Oat Fudge Bars, it’s essential to use old-fashioned rolled oats. These oats provide a delightful chewiness that complements the fudge layer perfectly. Quick oats can give a softer, mushier texture, which isn’t ideal for this recipe.
How long do these bars last, and how should I store them?
You can store your Starbucks Oat Fudge Bars in an airtight container at room temperature for up to 1 week. For extended freshness, they can be kept in the refrigerator for up to 2 weeks, but keep in mind that chilling may reduce their chewy texture. If you want to keep them longer, follow our freezing instructions below.
What are the steps for freezing these bars?
Freezing your Starbucks Oat Fudge Bars is a simple process! First, wrap each bar tightly in plastic wrap or aluminum foil. Then, place the wrapped bars in a freezer-safe bag. You can freeze them for up to 3 months. When you’re ready to enjoy, just thaw them in the refrigerator overnight or microwave for 15-20 seconds to warm them up!
How can I troubleshoot if my bars turn out dry?
If your Starbucks Oat Fudge Bars come out dry, it might be due to overbaking. Always keep an eye on the baking time and test for doneness a few minutes early.

Also, ensure you properly cream the butter and sugars, as inadequate creaming can affect moisture levels.
