Now that we have our ingredients prepared, let’s dive into the recipe! Gluten-Free Oat Fudge Bars are easier than you think. Follow these simple steps to make your own Starbucks Copycat Oat Fudge Bars:

Step 1: Preheat and Prepare

Preheat your oven to 350 degrees Fahrenheit. Grease an 8×8 inch baking pan and then line it with parchment paper.

Step 2: Make the Oat Layer

In a large bowl, combine 1 cup of oats, 3/4 cup of buckwheat flour, 1/4 cup of potato starch, 1/2 teaspoon of baking soda, 1/2 teaspoon of cinnamon, and a pinch of salt.

In a separate bowl, cream together 1/2 cup of unsalted butter and 1/2 cup of packed brown sugar until smooth. Beat in one egg and 1 teaspoon of vanilla before mixing into the dry ingredients.

Spread the oat mixture evenly into the bottom of the prepared baking pan.

Step 3: Make the Fudge Layer

In a medium saucepan, melt together 1/2 cup of unsalted butter, 1 cup of chocolate chips, and a can (14 ounces) of sweetened condensed milk, stirring occasionally until smooth.

Remove from heat and stir in 1 teaspoon of vanilla extract. Add 1 scoop or 30 grams of chocolate-flavored protein powder (optional) for extra protein boost.

Pour the fudge mixture over the oat layer in the pan. Use an offset spatula to spread it out evenly.

Step 4: Bake and Cool

Bake for about 25-30 minutes or until an inserted toothpick comes out clean. Let it cool completely on a wire rack before cutting into squares.

Voila! Your oat fudge bars are ready!

I recommend enjoying them warm with a cup of coffee or a cold glass of milk.

Note: Gluten-free flour can be substituted with regular flour for a traditional texture and taste. If you want to reduce the sugar content, you can substitute coconut sugar for brown sugar in the recipe.

If you’re looking for ways to customize this Gluten-Free Oat Fudge Bars recipe, then you come to the right place. There are several alternatives and variations to meet everyone’s taste preference, dietary restriction, or personal touch on this Starbucks copycat recipe.

For starters, you can alter the type of flour used in the recipe. Instead of buckwheat flour and potato starch blend, you can try almond flour, coconut flour, or a gluten-free all-purpose flour mix that suits your baking needs. Just keep in mind that every kind of flour has different absorption rates, which might affect the texture and consistency of these oat fudge bars.

If you want to make this recipe vegan-friendly and dairy-free, a good substitute for sweetened condensed milk is coconut condensed milk or homemade nut milk made from cashew or almonds. Non-dairy butter alternatives such as coconut oil or vegan butter can replace unsalted butter in the recipe.

To add some textures and flavors to the oatmeal base of these bars, mix-ins such as chopped nuts like pecans or walnuts, dried fruits like raisins or cranberries, or even shredded coconut will do the trick. Cinnamon can also be swapped with ground ginger or pumpkin pie spice for a different aroma.

If you’re aiming for a healthier version of these fudgy oat bars, consider reducing the amount of sugar by replacing some of it with natural sweeteners like maple syrup or honey. You can also add protein powder into the oat mixture to boost nutrition without sacrificing taste.

In conclusion, don’t be afraid to experiment with different substitutions and variations in this Gluten-Free Oat Fudge Bars recipe. With some creativity and experimentation, you might discover your own signature twist on these scrumptious oat fudge bars that suit your preferences perfectly.

You can also enjoy these oat fudge bars on their own. They are perfect as a quick breakfast or as grab-and-go snacks before you hit the gym.

Once you have prepared these delicious gluten-free oat fudge bars, you will probably want to make them a regular addition to your weekly snack rotations. However, it is not always feasible to bake them every week. Fortunately, oat fudge bars are a great make-ahead option.

To store them properly, first allow the bars to cool completely before cutting into squares or rectangles. Then, arrange them in a container with an airtight lid or cover tightly with plastic wrap. You can store the bars at room temperature for up to 3 days or in the refrigerator for up to 1 week without affecting their texture.

If you need to make oat fudge bars for a party, gathering, or simply to save time throughout your busy weekdays, you can also prepare the recipe ahead of time and freeze it for later. To do this, follow the recipe as directed and allow the bars to cool completely. Then arrange them in an airtight container and freeze for up to 2 months. When you’re ready to enjoy the bars, thaw overnight in the refrigerator before reheating.

Reheating is simple too! Preheat the oven to 350°F (180°C). Arrange the bars on a baking sheet and warm in the oven for 6-8 minutes until heated through. Or, if you’re short on time and looking for convenience, simply microwave each bar for 10-15 seconds until warmed through.

Oat fudge bars are a true delight and there’s no reason why they shouldn’t be readily available when hunger strikes. By following these storing and reheating tips, you can always have these delicious treats on hand whenever cravings hit!

If you want to create the perfect gluten-free oat fudge bars, there are a few key tips to keep in mind. As a barista and a coffee enthusiast, I have experimented with countless recipes over the years and these tips are some of my favorites.

1. Use parchment paper or aluminum foil to line your baking pan for easy removal and clean-up. The fudge layer is especially sticky, so this step will save you lots of time and headache.

2. Don’t skimp on the butter! This ingredient adds rich flavor and texture to the oat mixture and fudge layer. You can substitute with coconut oil or vegan butter if you prefer, but just make sure it’s still unsalted.

3. For an extra boost of protein, try adding a scoop of your favorite flavor protein powder to the oat mixture before baking. This will give your bars more staying power and keep you feeling full longer.

4. Be patient when cutting and serving the bars. They are soft and gooey when they come out of the oven, so wait until they cool completely before slicing them into squares. Put them in the fridge for about 30 minutes if you can’t wait that long.

5. If you want to make the fudge layer more chocolaty, stir in some extra chocolate chips after melting everything together. You can also sprinkle cinnamon or sea salt on top for an added twist.

6. Store your gluten-free oat fudge bars in an air-tight container at room temperature for up to four days, or in the fridge for up to one week. Reheat them in the oven (at 350 degrees F) for a few minutes to bring back their chewiness and texture.

By following these tips, you’ll be able to create perfect copies of Starbucks’ famous oat fudge bars from your own kitchen – gluten-free style! Whether you’re serving these bars with coffee or sharing them as a snack with your friends, they’re sure to win fans with their gooey texture and rich flavor.
