A good coffee cake recipe is a must-have. In fact, I have used this basic recipe so many times with so many variations. Why? Because I call it my lazy cake. Since it needs only a whisk to combine everything together. Often, in summer, I add some sliced fruits before baking to make a fruit-topped coffee cake such as apricot cake, peach cake, plum cake, etc. And yet, sometimes, I don't add the streusel over the fruit. Works perfectly every single time.

About this cake

This is a classic coffee cake batter with a streusel topping. Today, I am using my oil-based cake batter. Previously, I've shared my butter-based cake batter when I shared my sour cream coffee cake and cinnamon sugar coffee cake.

And, the best thing about this recipe, is you don't need a lot of equipment, not even an electric mixer. Of course, you can certainly use a mixer to make it, but a bowl and whisk are really all you need.

In addition, the streusel topping is one that makes a huge difference in such cakes, and this one is finger-licking delicious.

Ingredients and substitutes

• All-purpose flour - I use regular all-purpose flour. So, if you use cake flour, reduce the baking powder in the recipe by ½ tsp.
• Sugar - I'm using white sugar, but you can certainly use both white or brown.
• Oil - Gives this cake a light and airy texture. So, make sure to combine it well with the eggs.
• Sour cream - Gives a nice soft crumb and texture to the cake. And yet, if you don't have sour cream, Greek yogurt is often a great substitute. You can also make homemade sour cream.
• Vanilla - Priced like gold, but so important to use good quality vanilla. I make my own vanilla extract, bean paste, and vanilla sugar.

Step by step instructions

Prepare streusel

• In a bowl, combine brown sugar, salt, and flour.
• Grate the chilled butter - combine well.
• Place in the fridge to keep chilled.

Cake batter

• Grease and line a 9 x 9-inch square cake pan.
• Preheat the oven at 160 C / 320 F.
• Combine flour with baking powder, baking soda, and salt - set aside.
• Whip together the eggs and oil.
• Add the sugar, followed by the sour cream.
• Next, add the vanilla.
• Lastly, add the flour mixture. Combine well.

• Pour into the prepared baking pan. Use an offset spatula to spread evenly .
• Generously top with the prepared streusel mixture.

• Bake for 35 to 40 minutes or until a skewer inserted in the center comes out clean.
• Let cool in the pan for at least 10 minutes before slicing.
