This simple crumb cake is the BEST I ever tasted. The cake is so moist, and there is a ton of buttery crumb topping to die for. It's my aunt's recipe from the 1970's (hence the 1 pound of butter) and therefore of uttermost decadence, but oh so addictive! I've made this recipe so many times, with so many compliments. I basically eyeball the measurements now (I like a lot of cinnamon) but below is the original recipe.

Ingredient Checklist

Directions

Instructions Checklist
  • Preheat oven to 350 degrees F (175 degrees C). Grease a 12x18-inch jellyroll pan.

  • Beat the yellow cake mix, water, eggs, and 1/2 cup softened butter together with an electric mixer in a mixing bowl until thoroughly blended, about 2 minutes on medium speed. Pour the cake batter into the prepared jellyroll pan.

  • Bake in the preheated oven until the edges of the cake are light brown but the middle of the cake is still slightly gooey, 15 to 17 minutes.

  • While the cake is baking, mix together the brown sugar, cinnamon, vanilla extract, butter, and flour together in a large bowl until the mixture forms medium crumbs. Remove the cake from the oven, and press about 3/4 of the crumb topping onto the top of the almost-baked cake. Reserve the remaining topping.

  • Return the cake to the oven, and bake an additional 10 to 12 minutes, until the crumb topping is firm and the cake is cooked all the way through.

  • Remove the cake from the oven, and sprinkle with the remaining crumb topping. Let the cake cool to room temperature, and sprinkle with confectioners' sugar.

Cook's Notes

Overall, I found that margarine makes better crumbs - and there will be A LOT of crumb topping (just cut amounts back if it's too much).

For the image, I couldn't find my jellyroll pan so I used a 13x9 cake pan. I increased the first cooking time from 15 to 17 minutes to 25 to 27 minutes, which worked fine.

I don't know why my aunt changed the oven temperature as the cake mixes she used calls for 375. I just follow her directions.

Yum....I was looking for a classic crumb cake and this was great esp if you are a "more crumb. less cake" person. I added all crumbs to bake at once instead adding the rest later. I'll add a little more cinnamon next time. Read More

I've been making this cake for some time with a few tweaks. I always use a 13 x 9 pan but add one and a half cans of Comstock fruit filling (cherry, blueberry and apple seem to always be the biggest hits) on top of the baked cake, then press the crumb mixture on top of that..and bake the rest of the way. Thank you for jogging my memory about the vanilla extract. Doing it from memory..the crumb mixture seemed to be missing something. Now I know! I get rave reviews on this fruit crumbcake at work!

I used to make this cake all the time and lost the recipe years ago. Only difference - I use the "butter" cake mix. This is the best crumb cake. Thanks for posting. Read More

I usually don't review but after seeing mixed reviews I had to say something. This cake is really good and very easy. If you can follow instructions it won't be dry. How can people say it's dry but yet undercooked?? It was a hit at our town's spring block party. Read More

This review is just for the crumb topping-- if you are interested in making the whole cake read no further. I made this today because I had been dreaming of crumb cake and really more about the crumb than the cake. I had some cherries on hand that were starting to become questionable in freshness and so I made a cream-cheese cherry pound cake (recipe from cookrepublic.com) for the cake part. Then when it was almost done baking I sprinkled the crumb topping--ALL OF IT-- onto the top of the cake. After baking it for about ten minutes more with the heat turned up to 400 degrees to brown the top I pulled the baked cake out of the oven and let it sit out for about two hours to cool and set. Then.......... I cut a slice for myself. Delicious! The crumb topping was perfect-- thick crisp slightly sweet and slightly nutty in flavor. A new favorite! Read More

I made this cake and it was gone in 2 hours. I made a few changes. I added ground clove and ground ginger to the crumble. I also put pure pumpkin puree in between the layers. Before I put the crumble on I spread one large can of pumkin puree over the cake. To the puree I had added the same spices plus a scant tsp of salt. Everyone loved this version as well Read More

This is a great recipe! The crumbs were easy and they tasted delicious! I did change the recipe a bit but nothing too big. Instead of using 1 1/2 cups butter I used 1 cup margarine and 1/2 cup butter. Also instead of using a boxed cake I used a recipe for vanilla cake! The recipe was not from this site but you coud use a vanilla cake recipe from this site. I think it works better than a boxed cake mix. Overall this recipe was a big success! Everybody enjoyed it although the crumb was a little rich! It was still great though... It looked amazing and tasted even better! Thanks for the recipe! This is a keeper! Oh and definetly use a 9x13 pan... not a jellyroll pan. Read More
