Tips to Make Gluten Free Blueberry Oat Bars | Starbucks Copycat

Every baker has their secrets, and here are a few of mine:

• Chill the dough: Cooling it slightly before baking creates a better texture.
• Swapping sugars: Go wild and replace the granulated sugar with coconut sugar for a unique flavor twist!
• Don’t skip the salt: It heightens the flavors, making each bite a taste experience.

Variations

Mix it up! Want a different flavor? Toss in raspberries or sliced strawberries for a seasonal twist. For the vegan crowd, substitute the egg with flaxseed meal or applesauce, and use dairy-free butter to keep it friendly.

FAQs

Can I substitute regular flour for the gluten-free blend?
You can, but then you lose the "gluten free" status! Try to stick with the blends for best results.

Can I make these oat bars ahead of time?
Absolutely! Make them a few days in advance; just store them in the fridge for freshness.

What’s the best way to reheat them?
Microwave them for about 10-15 seconds, or pop them in the oven at 350°F for a quick warm-up.
