Blueberry Cake and Friendship

I was reminded of this coffee cake when I was out in California with a group of long time girlfriends (since our early teens) this past weekend.

Oh my goodness, we  laughed, shared, cried, giggled, listened, reminisced, dreamt, prayed with and encouraged one another. The security of being with friends who really know YOU, your history, and your family is truly priceless.

Don’t get me wrong, I love my husband and my boys, but sometimes we need the understanding, empathy and support of another woman. I would shrivel up without my family and girlfriends.

I was privileged to have grown up in the late 70’s and early 80’s with these girls in a unique situation that threw us together; all living on the same property with our families.

It was the best thing that could have happened to us during those tough adolescent years, we truly became sisters!

The older I get the more I realize the importance of these times with girlfriends who really know and love you, just as you are.

Be a Friend first

To be have a friend, one must BE a friend; give of yourself, even when you don’t have much to give.
Extend, risk and humble yourself to the beauty of authentic, real friendship.
Where truth can be told, in love; where you can see the good, the beauty, and even help heal deep wounds.
Through our vulnerability with one another we can encourage, hold up, and most especially pray for and with one another.

~ Kathleen

Friends who see through the extra pounds and wrinkles, to the sweet, kind, caring and vulnerable heart of that young girl that still lies somewhere beneath layers of now crepe-y skin; reminding you of the treasure you are to this world.

And so I encourage YOU my dear reader, to reach out to others; whether it’s re-kindling a friendship from long ago, making a new friend, or simply risking going deeper in a current friendship.

Don’t hesitate, jump in with your whole heart! You won’t regret it! I’m getting all emotional just writing this, so on to our Blueberry Cake Recipe!

What you need for blueberry crumb coffee cake

CRUMB TOPPING INGREDIENTS

• Light brown sugar
• Sugar | I use all natural cane sugar
• All-purpose flour | I use organic all purpose unbleached flour
• Butter (no substitutions), room temp

BLUEBERRY CRUMB CAKE INGREDIENTS

• All-purpose flour | I use organic all-purpose unbleached flour (Gluten Free flour may be substituted)
• Granulated Sugar | I use natural, unbleached cane sugar
• Baking powder | Gives the cake it’s rise
• Kosher Salt | a must have in any recipe!
• Butter | the real deal, no soft butter coming out of the fridge or blends.
• Milk | I always use whole milk in my recipes
• Egg | room temp if possible, large egg
• Fresh* Blueberries | washed and patted dry, any stems removed. *Frozen blueberries may be used. If time, thaw and rain, toss in a few tablespoons of flour to help blueberries from bleeding.

Giant Blueberry Muffin Glaze Ingredients

• Powdered sugar
• Vanilla extract
• Milk or Cream

How to make the best coffee cake

Step 1

• Wash blueberries and let sit on paper towels to dry.
• If frozen, remove from freezer and allow to thaw, if you totally spaced thawing, have no fear, you may just need to bake a little longer, but be sure to coat them in flour, see below.

Step 2 | Make Crumb (Streusel) Topping

• In a medium-large mixing bowl, combine your brown sugar, all natural cane sugar, all-purpose flour and cinnamon using a fork or mixer.
• Add softened butter* and mix well, using your fingers if necessary, until the mixture starts to stick together into large clumps/crumbs.
• It should hold together when pressed.
• I like to use my mixer, it takes a bit longer, but I feel like the butter is better distributed in the long run. But you can always just use a pastry cutter or your fingers to mix.

Look at those bodacious, beautiful, buttery crumbs!

KATHLEEN’S PRO TIP | Place crumb topping in fridge or freezer while making the cake batter, this will chill the butter once again, so your crumb topping doesn’t melt into your cake while baking.

Step 3 | Assemble the Coffee Cake

• In a large batter bowl or the bowl of a stand mixer, add all-purpose flour, all natural sugar, eggs, milk, butter, baking powder and salt.
• I’ve made it both ways, with putting all of your dry ingredients first, then your butter, then your liquids and the end batter was the same, so whatever works best for you.

• Mix on low, until combined, careful not to over mix, there might even be a few lumps and it’ll be fairly thick, don’t worry.

• Gently fold the blueberries into the batter, if using frozen blueberries see below.

How to stop frozen blueberries from “bleeding”

• When frozen blueberries thaw, it brings out all of the pigment that holds the color for these beautiful berries.
• In order to keep that color from “bleeding” into your dough, before folding in frozen blueberries, gently toss blueberries in a couple tablespoons of flour in a large bow.
• The flour helps absorb the color, but never fear, while it might make your cake purple, it’ll still taste terrific!

Below are two pictures, one of frozen (flour coated) blueberries and the other of fresh.

Step 4 | Baking the Blueberry Coffee Cake

• Lightly grease a 9″ springform pan or a 9″ deep square pan if you don’t have a springform pan.
• If desired for easier removal from pan, cut out a 9″ round (or square) of parchment, lightly spray with oil and place in bottom of pan.
• Try splitting the batter into two smaller 6″ springform pans in order to get two cakes from one prep! Freeze one or give one away. 

Blueberry Coffee Cake Pan Options

• Substitute a deep 9″ square or round pan, spray well with non-stick spray or line with parchment paper.
• Or use an 8″ springform pan, increasing baking time by 10 minutes or more.
• Or a 10″ springform (reduce bake time by 10 minutes or so).
• Split batter between 2 smaller pans, such as 2 – 6″ springform pans. Bake 30-40 minutes, putting foil on top if gets too brown. Freeze one for later or give one away to a neighbor and make their day!

• Crumble the crumb topping evenly over the top of the cake batter, leaving some larger chunks and some smaller so you have a traditional “crumble” topping. 
• Pop it in preheated 375º oven and bake it for 50-65 minutes until the top is golden and the center is cooked. If it starts getting too brown on top but isn’t done, carefully lay a piece of foil over the top.

How to Store Blueberry Coffee Cake

Store in fridge — good up to about a week, if it lasts that long. Or may be tightly wrapped and frozen.

Warm in microwave for a few seconds before devouring.

Substitutions

Not a blueberry fan? Substitute the same amount of fresh or frozen berries or even rhubarb (but paired with a sweeter berry)!

• Strawberries (sliced)
• Blackberries
• Raspberries
• Cherries or a mixture of the above

High Altitude Adjustments

No adjustments necessary for high altitude.

Gluten Free Blueberry Coffee Cake

I love when you can easily adapt a recipe to be gluten free! And this is a super easy one to adapt!

2. I tested with 1 cup GF All Purpose Flour, ½ cup GF Oat Flour and ½ Cup Almond Flour.
3. Reduce baking powder to 2 teaspoons
4. In crumb topping replace with half oat flour and half GF Ap Flour
5. Bake as directed!
