🍽 How to Serve

This breakfast cake is incredibly versatile and can be served in so many ways:

  • Pair with scrambled eggs for extra protein

  • Add a side of fresh fruit for a colorful plate

🧺 For Lunchboxes

  • Slice into squares or bars

  • Pack with cheese cubes or a boiled egg for balance

🥛 As a Snack

  • Serve with a cup of milk

  • Cut into small cubes for easy toddler snacking

  • Enjoy chilled straight from the fridge

🍓 For a Special Treat

  • Warm slightly and drizzle with a tiny bit of extra honey or maple syrup

  • Add a light spread of nut butter (for toddlers who safely consume nuts)

🔄 Substitutions & Swaps

This recipe is very forgiving, which makes it perfect for busy families. Here are some easy swaps you can make depending on what you have on hand:

Whole Milk Yogurt

  • Swap for plain Greek yogurt (it will make the cake slightly thicker and higher in protein)

  • Use dairy-free yogurt if needed (unsweetened works best)

Eggs

  • You can try flax eggs (1 tbsp ground flax + 2.5 tbsp water per egg), though the texture will be slightly denser

  • Mashed banana or unsweetened applesauce can replace egg for extra moisture (it will add more sweetness)

Butter

  • Replace with melted coconut oil

  • Use avocado oil or light olive oil for a neutral flavor

  • For dairy-free, any neutral oil works well

Honey (12 months +)

  • Swap with pure maple syrup but it will taste more like a pancake

  • Use date syrup for under 12 months of age

Oat Flour

  • Swap for 1 cup of All-purpose flour or you can use almond flour, although the texture will be different.

Mixed Berries

  • Use any berry you prefer, fresh or frozen

  • Try diced strawberries or wild blueberries is what we like best

  • Frozen berries work perfectly, no need to thaw

you can use an 8×8 square baking dish or a standard circle cake baking dish

Fold in berries of choice (fresh or frozen)
You can cover them with a little oat flour so they don't drop to the bottom. I did use a frozen mixed berry mix and they were quite sour, I recommend using fresh or a frozen berry you know are good and you've used before (ex: wild blueberries are great)
