a slice of Grandma’s Secret Blueberry Coffee Cake Recipe

Grandma. the kindest soul, with soft hands and an even softer heart. She was never one for speeches, but she had a way of showing love that didn’t need words. You knew it from the smell wafting through her kitchen, that warm, buttery, cinnamon-kissed scent of blueberry coffee cake cooling by the window.

No alarms could get us out of bed faster than that. Plates clinking, the hum of her old radio, the sound of her wooden spoon tapping the bowl, it was the symphony of childhood mornings.

But times have changed. Today, breakfasts are often rushed, pre-packaged, or skipped entirely. Still, deep down, we crave that feeling of warmth and home. So what if Grandma’s comfort food could meet today’s health goals, with a cleaner, lighter, and more nutritious spin?

If you’re looking for easy, wholesome breakfast ideas for kids that still feel homemade, this updated blueberry coffee cake will make your mornings smell like love again. Here’s our delicious, modern twist on nostalgia, healthier, creamier, and absolutely family-approved.

The Original Recipe That Started It All

Every tradition begins with a story, and this one starts with Grandma Donnie’s famous blueberry coffee cake. Her version, lovingly passed down (and now living online at AllRecipes), is the kind of family breakfast that has stood the test of time.

She used simple, everyday ingredients:

Flour

Sugar

Butter

Milk

Egg

Vanilla

baking powder 

and a generous scoop of blueberries, topped with a little cinnamon-sugar magic.

Baked to golden perfection, the result was tender, fragrant, and irresistibly comforting. Each square carried around 252 calories, 6g of fat, and 4g of protein, just the right fuel for long school days or busy mornings.

In her day, it was a balanced start: carbs for energy, fruit for sweetness, and love as the secret ingredient.

The Modern Twist: Healthier, Creamier, and Kid-Approved

Fast-forward to today, and our mornings are a whirlwind. We want quick, healthy, and allergy-friendly options — but without losing that homemade soul.

We swap regular milk for this creamy, plant-based upgrade that’s lactose-free and naturally rich in fibre. According to Healthline, beta-glucan, a soluble fibre from oats, supports heart health by helping to lower LDL (“bad”) cholesterol while promoting better digestion.

Our Modern Ingredient Swaps

Here’s how we give Grandma’s recipe a healthy glow-up while keeping the same melt-in-your-mouth flavour:

Oatbedient oat milk instead of dairy: Adds creamy texture, extra fibre, and nutrients — no fillers, no lactose, no nasties.

Coconut sugar instead of refined sugar: Lower glycaemic index, gentle on kids’ energy levels.

Chia or flaxseed for hidden omega-3s and extra fibre.

Lemon zest for a bright, antioxidant-rich kick.

These swaps don’t just “healthify” the recipe, they modernise it. We’ve taken Grandma’s comfort food and turned it into a nutritious breakfast idea for modern families who want food that loves them back.

How to Turn Grandma’s Cake into a Nutritious Morning Treat

Let’s break it down simply:

Use ½ cup of Oatbedient oat milk (instead of cow’s milk). Stir in ¾ cup of coconut sugar instead of white sugar. Add a tablespoon of chia or flaxseed to the dry mix. Zest half a lemon into your sugar before creaming it with butter.

That’s it, small swaps, big results. You’ll end up with the same tender crumb, the same sweet aroma, but a breakfast that fuels your family rather than just fills them.

Quick Recipe Summary

What you need:

Equipment:

9 x 9 inch square cake tin

Mixing bowls x 2

Whisk or electric hand mixer

Rubber spatula

Measuring cups and spoons

Zester or fine grater

Baking parchment

Ingredients:

2 cups flour

2 tsp baking powder

½ tsp salt

¾ cup coconut sugar

¼ cup butter (or half butter + olive oil)

1 egg

1 tsp vanilla

½ cup Oatbedient Oat M!lk Barista

2 cups blueberries

1 tbsp chia or flaxseed

Lemon zest (½ lemon)

1 tbsp coconut sugar + ½ tsp cinnamon for topping

Step by step

  1. Prep the tin and oven
    Line the base of a 9 x 9 inch tin with parchment and lightly grease the sides. Preheat the oven to 190°C or 375°F. Position a rack in the centre.
  2. Combine dry ingredients
    In a medium bowl whisk together flour, baking powder, salt and the chia or flax. This evenly disperses the leavening and seeds so you get a uniform crumb.
  3. Infuse the sugar with lemon
    In a large bowl add the coconut sugar and lemon zest. Rub them together with your fingertips for 20 to 30 seconds until fragrant. This releases citrus oils for brighter flavour.
  4. Cream the fat and sugar
    Add the softened butter to the lemon sugar. Beat with a hand mixer on medium for 1 to 2 minutes until lighter and slightly fluffy. If using half oil, beat in the butter first, then stream in the oil.
  5. Add egg and vanilla
    Beat in the egg until fully combined and glossy, then mix in the vanilla. Scrape down the bowl so there are no streaks.
  6. Alternate dry mix and oat milk
    Switch to low speed. Add one third of the dry mix, then half of the Oatbedient oat milk. Repeat and finish with the last third of dry mix. Mix only until the flour disappears. Do not overbeat or the cake will be tough.
  7. Fold in blueberries
    Using a spatula gently fold in the blueberries. If using frozen berries, work quickly to avoid streaking. A few purple swirls are fine.
  8. Pan and level
    Scrape the batter into the prepared tin. The batter will be thick. Spread evenly with a spatula, nudging into the corners.
  9. Add the cinnamon sugar
    Stir together 1 tablespoon coconut sugar and 1/2 teaspoon cinnamon. Sprinkle evenly over the surface.
  10. Bake
    Bake at 190°C or 375°F for 38 to 42 minutes. Start checking at 35 minutes. It is done when a toothpick inserted in the centre comes out with a few moist crumbs and no wet batter and the top springs back lightly to the touch.
  11. Cool
    Cool in the tin on a rack for 15 minutes. Lift out using the parchment and cool another 15 to 30 minutes before slicing. Warm slices hold together better if you cut with a sharp knife cleaned between cuts.
  12. Serve
    Serve slightly warm as is, or with a splash of Oatbedient on the side. Leftovers keep covered at room temperature for 24 hours or refrigerated for up to 4 days. Freeze well wrapped for up to 2 months.
