Easy Buttermilk Coffee Cake Recipe

Everyone in our family enjoys this adaptation from an Amish cookbook, our Buttermilk Coffee Cake.  We love making this coffee cake recipe for dessert and weekend brunch.  The kids may sneak a piece for a snack once in a while.

Each family member has offered a different comment about this cake that makes me laugh.

The first time I made this buttermilk coffee cake recipe my son insisted that I had made this cake before.  He recalled this Honey Bun Swirl Cake made from a box mix and similar, yet different.

This coffee cake is made from scratch, but almost as easy as using a box mix.  The streusel topping also lends a different flavor than icing.  Buttermilk gives the cake a rich, home-baked goodness flavor that is unmatched in my opinion.

My toddler is confident she made the cake because she “mixy up” the topping and dumped a couple measuring cups of flour and sugar in the mixing bowl.

My husband said the cake reminded him of one that his grandma used to make.  She used a smaller pan and the topping went much further down into the cake.

These are all simple and delicious recipes that our midwestern family enjoys eating!

How to Make Streusel for Coffee Cake

To get a smooth cake finish with melted butter in the streusel bake the cake about 2/3 of the baking time and then add the streusel and finish baking.

Some experimenting uncovered that using melted butter in a streusel and pouring it over freshly mixed batter will allow the butter to seep down into the cake and create little canyons throughout the baking process.  My husband isn’t sure how his grandma baked her coffee cake, but we wonder if she didn’t use this amount of topping with a lot of melted butter in a smaller pan to create this finish.

Beauty is in the eye of the beholder regarding which finish is preferable.  The taste is the same in each baking experiment.  Here is a picture of pouring the streusel on the batter before baking.

  1. For some reason my streusel didn’t come out crumbly. Sugar completely dissolved in melted butter and flour didn’t help at all. It was almost impossible to sprinkle it on top and it didn’t cover the whole cake like in the picture. What did I do wrong?

    1. So sorry to hear that! This is definitely a heavy streusel, but there should be plenty to spread over the pan. I always use regular butter, all-purpose flour and light brown sugar. If that doesn’t work I might try adding 1 – 2 more tablespoons of melted butter. I hope it goes better next time because we always love this cake!

  2. My thought is do not melt the butter. I personally find I get a mush mess n not crumbly. I’m baking it today n will try just soft butter maybe 4T. Will let you know. The cake looks n sound yummy n easy. I love both.

    1. Sorry not soft butter……chilled butter
