This Mixed Berry and Peanut Butter Streusel Cake is super soft and light in the middle, a little crisp on the edges, wonderfully crunchy on top with a streusel topping, studded with strawberries and raspberries, with a hint of sweetness and a big dose of delicious peanut flavor throughout!

Could a cake that is traditionally viewed as a sweet, be eaten for breakfast, be both indulgent and deceptively better for you at the same time?
This Mixed Berry and Peanut Butter Streusel Cake might very well be a game changer for me, because this is breakfast in dessert clothes, and it’s an absolute doozy!
Especially because I love a little breakfast treat in cake form like this coffee layer cake, or Sri Lankan butter cake. Plus it has peanuts! Can’t go wrong with that. I’ve got a bunch of peanut treats on the blog already like these easy buckeyes, peanut brittle, peanut butter hot chocolate, chocolate peanut cake, peanut butter berry smoothie etc.! You get the picture right?

I have tried this JIF’s peanut powder in several different ways – in smoothies, on toast, sprinkled on cereal, in my coffee and even created an indulgent pudding too.
But what my husband and I loved the most was this breakfast slice without a doubt – this gorgeous breakfast Mixed Berry and Peanut Butter Streusel Cake is such a great way to start the day because it’s not overly sweet, it’s got protein in the form of the peanut powder and fruits.

So whether you call it a streusel cake, breakfast slice OR coffee cake – you and I will agree on one thing – IT TASTES AMAZING!

Why I love this peanut butter streusel cake
- It’s a soft and light cake, studded with strawberries and raspberries (you can even use blackberries) with edges that are a little crisp, and a beautifully crunchy streusel top made with flour and oats, and it incorporates more of that wonderful peanut powder as well.
- The cake itself has just a hint of sweetness, and not overly sweet AT ALL.
- There’s a hint of salt in the streusel which is a lovely touch, but most of all, what you get is the peanut flavour throughout this streusel cake and it’s just freaking awesome! It’s like peanut butter and jelly in a cake slice. But dare I say, even better!?!
- You could have this for breakfast (with a cup of coffee? yum!), lunch, tea time, dinner, dessert, whatever. We’ve done it all.
