Streusel Topping Recipe

SourcreamBlueberrycoffeecake1 Streusel Topping Recipe

This last weekend we attended a potluck for our daughters’ swim team.  I brought this sour cream blueberry coffee cake ( a slightly adapted recipe from the one I made here) because I didn’t have any buttermilk for my original recipe.  As a result, the sour cream version is heavenly.  But what I love the most is the streusel topping.  The streusel topping is versatile for any cake or muffin recipe calling for streusel.  Full of brown sugar and cinnamon, the texture of this streusel topping is perfect.  Enjoy!

Streusel Topping Recipe


5 tbs. of cold butter, cubed in 1/2” squares

3/4 cup of AP flour

1 cup of brown sugar

2 tsp. of cinnamon

1/4 tsp. of salt


In a food processor or by hand, mix brown sugar, flour, cinnamon, and cold butter until the mixture is crumbly. If mixing by hand, just use your fingertips or the back of a fork. If you are using a food processor just pulsate everything until you get a crumb mixture. For bigger clumps, form little balls with your hand.  Add streusel topping mixture to the tops of your cake or muffins gently pressing everything down.  Bake as directed for your cake.

Sour Cream Blueberry Coffee Cake Recipe

2 tsp. of baking powder

1 cup of sugar

1 – 1/2 sticks of butter, softened

1/2 tsp. of salt

1 egg

2 tsp. of vanilla extract

Preheat oven to 350 degrees. Grease 8×8 square pan with non stick spray. In a medium mixing bowl, cream butter and sugar for 3-4 minutes until light in color and creamy. Add egg, sour cream, and vanilla and cream for an additional 2 minutes. Add salt, baking powder, and all-purpose flour and mix on medium speed.  Mix batter until everything is fully incorporated, approx. 3-5 minutes. Batter will be nice and thick. Gently fold in fresh blueberries and pour batter into pan. Top with streusel topping and bake for 60 minutes or until done.  Enjoy!

    I could never get the streusel topping right. It’s pretty simple, too. I’ve got to give you version a try. Awesome coffee cake. I’d love to have some of that for breakfast!

    You know that I’m obsessed with anything with a streusel topping! This looks super yumm! And it’s a great way to utilize all of the blueberries that I have. Will have to give your recipe a try.

    By the way, did you use light brown sugar or dark brown sugar?

    YUM-that coffee cake looks absolutely delicious! I love steusel toppings, you can literally add them to any sweet treat and they’ll always turn out wonderful! I made one with a cup of oats added and poured it over a peach & blackberry crisp-delicious!

    5 Tablespoons not lbs, if that is what you are saying.
    I am going to make this for a picnic tomorrow. I know no one else will be bringing it. Can’t wait to try it.

    Oh wow – this looks amaaaazing! I cannot wait to make it, and I think it is a must to use our favorite Kamut Khorasan Wheat flour instead of AP! Just way more nutritional value and the flavor and texture is wonderful! Cannot wait, thank you!

    I made this recipe but put the batter in cupcake tins to make muffins. I made the mistake of using 1/2 cup (1 stick) of butter instead of a 1/2 stick of butter. Also, I had a lemon so I put some lemon zest in the batter. The muffins came out yummy, despite my error! I will definitely make this again! Thanks for the recipe, Alice!

    i tried the recipe–the batter was too dry. i think it should be 1/2 cup of butter instead of 1/2 stick. that worked.

    Is something missing in this recipe? I added more butter based on the comments here, but the batter was still as thick as cookie dough and the coffee cake was really dry. The directions say “Add egg, sour cream, and vanilla and cream,” but there was no cream listed in the ingredients. Maybe it got left off? Anyway, I wasted an hour and $6 worth of blueberries.

    This is SO yummy! I made the recipe exactly as written, it was very thick, like cookie dough. I also didn’t leave it in the oven for a full hour, i began testing for doness at a half our and after 50 minutes it was done!

    I made this for my “kids” (24 and 13 y.o.) who LOVE blueberry muffins…they both liked it and had the same comment…the topping over powered the blueberry cake part…like it was too much which I was surpised since they usually ask me to add extra crumbs on my coffee cake. I think I will follow the botom of the recipe but use my regular crumb topping that comes out lighter in color and taste….I wish I could have tried it since it smelled and looked wonderful but I am dieting…maybe I will freeze a piece for my “cheat day” lol. Thanks for that nice recipe!..oh and btw lemonlean…it meant TO CREAM not add cream ok?

    OMG! This is so delicious! I put about 1/2 c more of blueberries and my blueberries were large. We ate it warm. It doesn’t rise really high but it is so good and tasty, buttery flavor. Love it! I did not put the streusel topping in the processor but just clumped it with my hands and it turned out very well.
