Why This Recipe Works
- Fast and fuss-free: Mix in one mug, microwave, and eat. No bowls to clean.
- Moist and fluffy texture: Applesauce and a touch of fat keep it tender, not rubbery.
- Protein-packed: Protein powder turns a snack into a satisfying mini meal.
- Gluten free by design: Uses almond flour and certified gluten-free oats.
- Balanced flavor: Cinnamon, vanilla, and a hint of maple make it taste like a cozy fall dessert.
What You’ll Need
- 1 small egg (or 3 tablespoons liquid egg whites)
- 2 tablespoons unsweetened applesauce
- 1 tablespoon milk (dairy or almond/oat milk)
- 1 tablespoon maple syrup (or honey, or sugar substitute to taste)
- 1/2 teaspoon vanilla extract
- 2 tablespoons almond flour
- 2 tablespoons oat flour (use certified gluten-free; or blitz oats in a blender)
- 1 scoop (about 20–30 g) vanilla or unflavored whey or plant protein
- 1/2 teaspoon ground cinnamon
- 1/4 teaspoon baking powder (gluten free)
- Pinch of salt
- 2 tablespoons finely diced apple (peeled if you like)
- 1 teaspoon butter or coconut oil (melted; optional but recommended for moisture)
- Optional toppings: extra cinnamon, a drizzle of maple, Greek yogurt, or a few chopped nuts
How to Make It
- Prep your mug: Use a large microwave-safe mug and lightly grease it to prevent sticking.
- Whisk wet ingredients: Add egg, applesauce, milk, maple syrup, vanilla, and melted butter/oil.
Whisk with a fork until smooth.
- Add dry ingredients: Stir in almond flour, oat flour, protein powder, cinnamon, baking powder, and salt. Mix until just combined.
- Fold in apple: Gently stir in the diced apple so it’s evenly distributed.
- Microwave: Cook on high for 60–90 seconds. Start checking at 60 seconds.
The top should look set but still moist. Avoid overcooking.
- Rest: Let it stand for 30–60 seconds to finish steaming and become fluffy.
- Top and enjoy: Add a sprinkle of cinnamon, a spoon of Greek yogurt, or a drizzle of maple. Serve warm.
Storage Instructions
- Same-day best: Mug cakes are at their peak right after cooking.
- Short-term: Cover and refrigerate for up to 24 hours.
Reheat 10–15 seconds in the microwave.
- Make-ahead tip: Pre-mix dry ingredients in small jars or bags. When ready, add wet ingredients and cook.
Why This is Good for You
- Protein helps satiety: Keeps you full longer and supports muscle recovery.
- Fiber from oats and apple: Supports digestion and steady energy.
- Lower sugar potential: Sweeten to taste or use a zero-calorie sweetener.
- Healthy fats: Almond flour and a touch of butter or coconut oil improve texture and satisfaction.
Common Mistakes to Avoid
- Overcooking: Dry, rubbery mug cakes happen fast. Stop when the center is just set.
- Too much protein powder: It can make the cake dense.
Stick to one scoop.
- Skipping fat: A small amount keeps the crumb tender and flavorful.
- Wrong mug size: A small mug can cause overflow. Use a large mug or small bowl.
- Not adjusting for protein type: Plant protein can absorb more liquid. Add 1–2 extra teaspoons of milk if needed.
Alternatives
- Dairy free: Use plant milk and a plant-based protein powder.
- Egg free: Swap the egg for 3 tablespoons aquafaba or 1 tablespoon ground flax + 2.5 tablespoons water (rest 5 minutes).
- No oats: Replace oat flour with more almond flour and add 1 teaspoon coconut flour to balance moisture.
- Flavor twists: Add a pinch of nutmeg, ginger, or cardamom.
Stir in raisins or chopped walnuts for texture.
- Lower sugar: Use half the maple syrup and add a few drops of liquid stevia or monk fruit.
FAQ
Can I bake this in the oven?
Yes. Bake at 350°F (175°C) in an oven-safe ramekin for 12–15 minutes, or until the center is just set.
Which protein powder works best?
Whey isolate or a whey blend usually yields the softest texture. If using pea or brown rice protein, add a teaspoon or two more milk.
How do I make it sweeter without more sugar?
Use a few drops of stevia or monk fruit, and keep a small amount of maple syrup for flavor depth.
Can I use coconut flour?
Use it sparingly.
If swapping, start with 1 teaspoon coconut flour and add a bit more milk. Coconut flour absorbs a lot of moisture.
What if I don’t have applesauce?
Mash a few spoonfuls of ripe banana or use plain Greek yogurt. The flavor will change slightly but the texture stays moist.
Is it truly gluten free?
Yes, as long as you use certified gluten-free oats/oat flour and gluten-free baking powder.
Always check labels.
