Baking with Olivia and Caroline

August 2022 Recipe – Blueberry Crumb Cake

By Published On: August 1st, 2022

What a perfect cake to have for breakfast or snacking. Perfect for a summer picnic and parties. Caroline and I made this after picking blueberries from a local farm in Red Hook, NY. I have been doing a lot of fruit picking this summer. Last month I picked some of the best cherries I’ve ever eaten. If you have never gone fruit picking, we highly suggest it. There’s something about picking way more fruit than you even know what to do with, nearly getting sick from eating so much, then missing them as soon as they’re gone.

Lost and found

This recipe goes back quite a ways. A lot of the recipes we share hold fond memories in our hearts and tummies. My mother got the recipe from her good friend’s mom years ago and was passed down to me. It was lost for a while among the massive disorganized mess of recipe cards and print outs, but we found it and made it – it was gone in a matter of hours. This cake is incredible.

This cake is so moist and has just the perfect amount of sweetness. It is an easy cake to assemble and you probably already have all the ingredients. You can make these with frozen blueberries, just make sure you thaw them first.

Cake ingredients

2 cups sifted flour
2 tsp baking powder
½ tsp salt
¼ cup room-temperature butter
¾ cup sugar
½ tsp vanilla
1 egg
½ cup milk
2 cups blueberries

Crumb topping ingredients

½ cup sugar
¼ cup flour
½ tsp cinnamon
¼ cup room-temperature butter


Preheat oven to 350 degrees. Grease and flour a 8”x9” square pan. Sift flour together with baking powder and salt; set aside. Cream butter on medium speed, beat in sugar. Add egg and milk and beat until smooth.

Add dry ingredients. Do not over mix. Fold in the blueberries with a wooden spoon or spatula. Spread batter in the pan.

Mix with a fork or a pastry blender all the crumb topping ingredients and sprinkle evenly on top of the cake mixture. Bake for 40-45 minutes. Allow to cool before cutting.
