Ingredient Notes

To get that perfect “cake-like” texture while keeping things vegan and gluten-free, we use a specific blend of flours. Here is what you’ll need:

• Oat Flour: This is the backbone of the recipe. It provides a soft, hearty texture. Pro tip: You can make your own by blending dry rolled oats in a high-speed blender until they reach a fine, powdery consistency.
• Almond Meal: This adds healthy fats and moisture, ensuring the muffins don’t turn out “gummy,” a common pitfall in gluten-free baking.
• Gluten-Free All Purpose Flour: Just a quarter cup helps with the structure and lift.
• Ripe Banana: You want a banana with a few brown spots. It adds sweetness and acts as the “egg” to hold everything together.
• Natural Vegan Sprinkles: Look for brands that use vegetable dyes (like beet or turmeric) instead of artificial colors to keep these as “clean” as possible.
• Vanilla Extract: Don’t skimp here! The 1.5 teaspoons of vanilla is what gives these that classic “cake” aroma.

Step-by-Step Instructions

1. Prep the Oven and Pan:
Preheat your oven to 350°F (175°C). You can either line your muffin tin with paper liners or grease it generously with coconut oil or a non-stick spray.

2. Blend the Wet Base:
Place your ripe banana, almond milk, vanilla extract, and sugar into a blender. Blend on high until the mixture is completely liquid and smooth. This ensures the sugar is dissolved and the banana is fully incorporated.

3. Whisk the Dry Ingredients:
In a large mixing bowl, whisk together the oat flour, almond meal, gluten-free flour, and baking powder. Make sure there are no large clumps of almond meal.

4. Combine:
Pour the blender contents into the dry ingredients. Stir gently with a spatula until just combined. Don’t overmix! Fold in the star of the show: the sprinkles.

5. Fill and Bake:
Distribute the batter evenly into your muffin tin. Fill each cup about 3/4 of the way to allow room for that beautiful dome to rise. Bake for 22 minutes or until a toothpick comes out clean.

6. The Cooling Rule:
This is the hardest part! You must let these cool for at least 30 minutes in the pan. Gluten-free and vegan bakes need this time to “set.” If you pull them out too early, they might crumble.

Expert Tips for Best Results

• Measure Flour Correctly: If you aren’t using a scale, use the “spoon and level” method for your flour. Never scoop directly with the measuring cup, as it packs the flour down and leads to dense muffins.
• Check Your Baking Powder: Since we aren’t using eggs, the baking powder does all the heavy lifting for the rise. Make sure yours is fresh!
• Sprinkle Choice: For the best visual pop, use “jimmies” (the long ones) rather than “nonpareils” (the tiny balls). Nonpareils tend to bleed their color into the batter more quickly.
• Frosting Tip: If you choose to add frosting, wait until the muffins are completely cold to the touch. If they are even slightly warm, the frosting will melt into a glaze.

Variations and Substitutions

• Sugar-Free: For a refined sugar-free version, use coconut sugar in the batter and skip the sprinkles and frosting.
• Chocolate Chip: Not a fan of sprinkles? Swap them for vegan mini chocolate chips for a “stracciatella” cake vibe.
• Nut-Free: If you have a nut allergy, you can try replacing the almond meal with more oat flour, though the texture will be slightly denser. Swap the almond milk for soy or oat milk.
• Oil-Free: This recipe is already naturally oil-free thanks to the almond meal and banana!

Storage and Freezing

To Store: Keep these muffins in an airtight container at room temperature for up to 2 days. For longer freshness, move them to the refrigerator for up to 5 days.

To Freeze: These freeze beautifully! Wrap individual muffins (unfrosted) in plastic wrap and place them in a freezer-safe bag. They will stay fresh for up to 3 months. Thaw at room temperature or microwave for 20 seconds for a “fresh from the oven” feel.

FAQ

Can I use a different flour?
While you can experiment, the oat/almond/GF-AP blend is what gives these the perfect crumb. Replacing them with 100% all-purpose flour will change the moisture requirements.

My muffins are sticking to the liners, why?
Vegan and gluten-free muffins tend to stick to paper more than traditional muffins. To prevent this, spray the inside of your paper liners with a little oil, or wait until they are completely cooled before peeling.

Can I make these into mini muffins?
Yes! Adjust the bake time to approximately 12–15 minutes.
