Something a little bit different from me today. Instead of a cake decorating tutorial, I have a recipe to share. If you like cinnamon and you’re looking for a delicious but easy autumnal treat, then this one is definitely for you! These cinnamon streusel slices are so easy to make! The warming smell of cinnamon while baking is perfect for these cool autumnal afternoons. Plus, just look at that colour, how more autumnal can you get?

Now this recipe, as with most of my recipes, is adapted from an old one. As you may know, I love old traditional recipes which are simple yet yield the most amazing results! They usually only need a few ingredients, therefore reducing cost, which is even more necessary these days with prices on the rise. This particular recipe is adapted from an old childhood recipe book that was created by my primary school. Being over 40 years old, it’s full of lots of old family favourite bakes! I’ve always kept this book dear to me and over the years I’ve played with and developed the recipes.

What sets this streusel slice apart from other recipes is that the base is more of a cake than a shortbread or biscuit. The sponge is so light and fluffy it practically melts in your mouth! The streusel topping is deliciously warming and you get that little crunch of cinnamon with every bite!

Look at that beautiful cinnamon crunchy topping on top of that delicious fluffy sponge!

So the full recipe is at the bottom of the page, but I just thought I would take you through some helpful tips first.

Cinnamon Streusel Topping

The cinnamon streusel topping is really simple to make. Just whisk all the dry ingredients together and then add the cold diced butter. I like to fully coat the butter in the dry ingredients before gently rubbing it in to make a lumpy breadcrumb consistency. My tip here is to be gentle and not to rush. It may not look like it’s coming together, but trust me it will. Also use quite a big bowl, so you have enough room for your hands. You will end up with something like the image below.

Cake

The cake is really simple to make. Make sure all your ingredients are room temperature. Add all the dry ingredients into a bowl and then the margarine and eggs. Combine the ingredients together and then beat on high for about 1 minute until a smooth consistency. Pour the mixture into a lined tin, making sure it reaches all the corners.

Sprinkle the topping all over the cake batter, ensuring an even cover.

Once baked, it will look like the image below.

Taking the bake out of the tin may seem scary, but the topping doesn’t fall off! I run a knife around the edge to ensure they are not stuck to the tin. I then turn the tin upside down onto a chopping board. After removing the tin, I carefully peel away the greaseproof paper and then using a cooling rack, I carefully flip the bake over.

If like me, you love the old traditional recipes, then you may also want to take a look at my great grandmother’s coconut buns recipe. They are truly delicious and are a firm family favourite! Click the image below to take a look. Read on for the full cinnamon streusel slice recipe.

A simple but delicious cinnamon streusel slice recipe. The perfect treat for those autumn afternoons!
Prep Time 20 mins
Cook Time 30 mins
Course Afternoon Treat, Dessert, Snack
Servings 8 slices

Ingredients
  

Topping

  • 80 g Plain Flour
  • 1 tsp Ground Cinnamon
  • 80 g Light Soft Brown Sugar
  • 70 g Cold Diced Unsalted Butter
  • Pinch of salt

Cake

  • 112 g Soft Margarine
  • 112 g Caster Sugar
  • 2 Medium Eggs
  • 112 g Self Raising Flour

Instructions
 

  • Preheat your over to 170° Fan. Grease the sides and bottom of an 8 inch square cake tin. Line the bottom with greaseproof paper and then grease this too. I use a pastry brush to grease my tins with margarine.

Topping

  • Sift the flour into a bowl. Add the salt, cinnamon and sugar and mix them together. Add the butter. Gently rub the butter into the dry ingredients with your fingers until you have a lumpy breadcrumb consistency. It will look a little like wet sand.

Cake

  • Sift the flour into a bowl. Add the rest of the ingredients and beat until you reach a smooth consistency. I used a hand held mixer to do this and took me just over a minute. Pour the mixture into your lined tin, ensuring you reach all of the corners.
  • Now scatter your topping mixture over the top of your cake mix. Try to get an even spread.
  • Place your tin in the centre of a preheated oven for approximately 25-30 minutes. You can test if it is fully baked by inserting a cake skewer in the middle. If it comes out clean, then it's ready. If not, give it another 2 minutes and try again.

Notes

Make sure all your cake ingredients are at room temperature. This helps to prevent curdling and produce a light fluffy sponge.
Once baked, leave to cool for about 15 minutes, then carefully turn out onto a cooling rack and remove the greaseproof  paper. Flip it back the right way up and let it cool fully before cutting into slices or squares. (I sandwich the bake between the cooling rack and a small shopping board and then gently turn it over.)
