What is the difference between coffee cake and crumb cake?

There is only a slight difference between these two cakes. Crumb cake tends to have a thicker, more prominent streusel topping. Coffee cake, on the other hand, has a thinner layer of topping with the bulk of the dessert being the cake.

What is crumble topping/ streusel topping made of?

This yummy topping is made of a few simple ingredients:

  • Reserved Cake mix
  • All-purpose flour
  • Brown sugar
  • Butter
  • Cinnamon powder

Why is my cake dry and crumbly?

There are typically two main reasons for this. First, you may have added too much flour. Be sure to measure correctly and level it off evenly. Second, the cake might be overcooked and became dry. Be sure to follow all directions while keeping an eye on your cake and know the quirks of your oven- each is unique.

Why is my cake dense and rubbery?

Oftentimes a dense cake is a sign of too much liquid. Sometimes even too much sugar or over-mixing can be the culprit. Be sure to measure all ingredients according to the directions and cook at the right temperature to prevent your cake from falling, creating a more dense cake.

Cake toppings

For this cake, I did a simple glaze, but there are many different options to drizzle over your cake:

Variations for crumble cake

Double/ Thick crumb- Double streusel topping ingredients for an even thicker top layer.

Add other spices– I only used cinnamon, but you can also use nutmeg, cloves, allspice, or even pumpkin spice.

Add nuts to topping– Try roughly chopped walnuts, almonds pecans for an extra crunch and layer of flavor.

Layer on the fruit– Add dried cranberries, dried cherries or coconut flakes in the batter or topping. You can also add a thin layer of fruit pie filling before putting on the streusel for a German-inspired dessert. Here are some tasty fillings: Raspberry Pie Filling or Peach Pie Filling or Apple Pie Filling.

Try other cake flavors- I used a yellow cake mix for the classic version but you can try chocolate, lemon, pumpkin for a different flavor profile altogether.

Tips and techniques

Don’t over-mix cake batter- Because that can cause the cake to collapse during baking and it can also become dense and rubbery.

Grease pan- Because that prevents the cake from sticking to the pan.

Use unsalted butter- So that your cake doesn’t taste too salty.

Melt butter– For the right texture in the streusel mixture.

Reduce amount of spice– If you prefer a milder tasting cake.

How to know if cake is done baking? Insert a toothpick in the center of the cake. If it comes out clean the cake is done. If the toothpick comes out sticky, the cake needs more time to cook.

Use room temperature ingredients– Because that allows the ingredients to blend together smoothly and evenly.

Don’t forget to reserve some cake mix- You will need it for the topping.

Topping mixture is supposed to be crumbly- Please don’t pour more liquid or butter to thin it out.

Don’t glaze a warm cake– Because it spreads and melts all over the cake and looks messy.

Make ahead instructions– You can make this cake and store it in an air-tight container in the fridge for up to 2 days before serving.

Refrigerate- Leftovers can be stored in a sealed container in the fridge for up to 3 days.

Freeze– Once the cake cools to room temperature, store in an airtight container for up to 2 months and then thaw overnight in fridge. The topping won’t be as crunchy any more.

  1. Exelent cake. Easy and delicious coffee cake.5 stars

  2. I love making this….always a hit! Try making it with a red velvet, spice cake or even chocolate cake mix…they’re all great5 stars

  3. I made this cake from another similar recipe. We loved it. Thought I had saved the recipe but couldn’t find it. I used your recipe and found the cake to be too dry. I don’t believe the other recipe added flour to the mix and feel that caused it to be more dry.  4 stars
