During the fall semester of my first-grade year, the teacher asked every child to bring a copy of an apple recipe to class. We then cut out these recipes in the shape of an apple, cut out two pieces of red construction paper in the shape of an apple, and stapled all the papers together. My mom still has this first-grade recipe book all about apples. One recipe we have made from this book every fall is apple cake with buttermilk sauce.

• Baking soda
• Salt
• Cinnamon
• Baking powder
• Organic olive oil

How to Make Apple Cake with Buttermilk Sauce

Step 1: Peel and chop four apples. To keep the cut apples from turning brown, I add lemon juice to the bowl of chopped apples and stir.

Step 2: Mill soft white wheat berries. If desired, place a stainless steel mixing bowl on a kitchen scale and weigh your ingredients instead of using measuring cups. I place both weight and measuring cup amounts for the ingredients in the recipe card. Put fresh milled flour in a mixing bowl along with baking soda, salt, ground cinnamon, and baking powder. Set aside.

Step 3: In a different mixing bowl, combine olive oil with organic sugar. Add eggs, milk, and vanilla extract. Slowly incorporate your flour mixture into the wet ingredients. Lastly, stir in the diced apples with a silicone spatula.

Step 4: Pour into a greased and floured 9×13 baking dish and bake for 45 minutes at 350°F. Check to see if it’s done by poking a toothpick in the middle. If the toothpick comes out clean or with only a few crumbs attached, the cake is done.

Step 5: As soon as you take the cake out of the oven, make the buttermilk sauce. Melt butter in a pan. Whisk in brown sugar and buttermilk. Bring to a boil and whisk in baking soda. Turn off the burner and take pan off the heat. Let the buttermilk sauce sit while the cake cools for ten minutes.

Step 6: Once the cake has cooled for ten minutes, poke the top with a toothpick several times. Pour hot buttermilk sauce over the entire cake. Let sit for one hour before serving.

Notes

• This recipe works great with fresh milled flour. But if you don’t have any available, organic all-purpose flour is delicious too! Instructions in the recipe.

How to Store Apple Cake with Buttermilk Sauce

Airtight container: I store this cake in a 9×13 baking dish with a lid on the counter. Storing cakes in the refrigerator can dry them out. It never lasts long, so I don’t have to worry about it going bad! You could also put this cake in an airtight container. This cake actually tastes better the next day once the flavors have had a chance to blend.

Freezer: If freezing the whole baking dish, you can wrap the baking dish in plastic wrap, then in aluminum foil. You could also divide the apple cake into smaller portions and freeze in freezer safe containers or freezer bags. 

FAQS

I don’t have fresh milled flour. Can I still make this apple cake recipe?

Of course! You can substitute all-purpose flour. Simply use 3 cups of flour for this option.

Can I make this apple cake with buttermilk sauce ahead of time?

Of course you can! If making more than a day in advance, I would advise sticking the whole pan in the freezer to retain freshness.
