How to Make Gluten-Free Rhubarb Crumble Muffins: Step-by-Step
Ready to get baking? Here’s how to whip up a batch of these amazing gluten-free rhubarb muffins:
- Get Started: Preheat oven to 425 degrees Fahrenheit (if your oven runs hot or you are unsure, preheat to 375 degrees instead), and line a muffin tin with muffin liners.
- Mix the Dry Ingredients: In a medium bowl, sift the gluten free flour, baking soda, baking powder, and salt together. Add the coconut sugar and mix well. Set aside.
- Combine the Wet Ingredients: In another medium bowl, add the coconut milk, lemon juice, melted coconut oil, vanilla extract, and egg or egg replacer and whisk together until well combined.
- Combine Wet and Dry: Add the chopped rhubarb to the dry mixture and gently toss until well combined. Create a well in the centre of the dry mixture and pour the wet mixture into the dry. Quickly and gently mix the batter until just combined. The batter will be lumpy, which is ok; do not over-mix.
- Make the Crumble: In a separate small heat-proof bowl mix the melted butter or coconut oil, cinnamon, coconut sugar, and vanilla bean powder. Set aside.
- Assemble and Bake: Spoon the batter two-thirds full into the prepared muffin cups. Sprinkle a small amount of the cinnamon crumble mixture on top of the muffins. Bake for 15-20 minutes (25-35 minutes if baking at 375 degrees), or until a toothpick inserted into the centre of the muffins comes out clean.
- Enjoy! xoxo
Pro Tips for Perfect Gluten-Free Rhubarb Muffins
Want to make sure your muffins turn out perfectly every time? Here are a few of my top tips:
- Use a Good Quality Gluten-Free Flour: Not all gluten-free flours are created equal. I recommend using a blend that contains a mix of whole grain gluten-free flour, like brown rice flour and oat flour, for the best texture.
- Don’t Overmix the Batter: Overmixing can lead to tough muffins. Mix until just combined. It’s okay if the batter is a little lumpy.
- Use Fresh Rhubarb: Fresh rhubarb will give you the best flavor and texture. If you only have frozen, thaw it completely and drain off any excess liquid before using.
- Adjust Baking Time as Needed: Every oven is different, so keep an eye on your muffins and adjust the baking time as needed. They’re done when a toothpick inserted into the center comes out clean.
- Let Them Cool Completely: I know it’s tempting to dig in right away, but letting the muffins cool completely will help them set up and prevent them from being too crumbly.
Common Mistakes to Avoid
Even though this recipe is easy, here are a few common mistakes to watch out for:
- Using the Wrong Flour: Make sure you’re using a gluten-free flour blend specifically designed for baking.
- Overmixing: As I mentioned before, overmixing is a big no-no.
- Not Measuring Accurately: Baking is a science, so accurate measurements are key. Use measuring cups and spoons, and level off the ingredients.
- Opening the Oven Too Early: Resist the urge to peek! Opening the oven door can cause the muffins to collapse.
- Not Storing Properly: Store your muffins in an airtight container to keep them fresh.
Rhubarb Muffin Variations
Want to mix things up a bit? Here are a few fun variations you can try:
- Strawberry Rhubarb Muffins: Add 1/2 cup of chopped strawberries to the batter for a burst of extra sweetness. These strawberry rhubarb muffins gluten free are amazing.
- Almond Flour Rhubarb Muffins: Substitute some of the gluten-free flour with almond flour for a nutty flavor.
- Rhubarb Coffee Cake Muffins: Add a swirl of cinnamon streusel to the top of the muffins for a coffee cake vibe. These paleo rhubarb coffee cake muffins are delicious!
- Sour Cream Rhubarb Muffins: Add 1/4 cup of sour cream to the batter for extra moisture.
- Vanilla Bean Rhubarb Muffins: Use fresh vanilla bean instead of vanilla extract for a richer flavor.
How to Store Your Gluten-Free Rhubarb Muffins
These muffins are best enjoyed fresh, but they can be stored for later. Store them in an airtight container at room temperature for up to 3 days, or in the refrigerator for up to a week. You can also freeze them for up to 2 months. Just make sure to wrap them tightly in plastic wrap before freezing.
Frequently Asked Questions (FAQ)
Got questions? I’ve got answers!
- Can I use frozen rhubarb? Yes, you can use frozen rhubarb. Just make sure to thaw it completely and drain off any excess liquid before using.
