Summer-fresh strawberries and peaches join forces in this streusel-covered strawberry peach crumb buckle that’s a perfect summer coffee cake or dessert!

Forget about ice cream being your fallback summer dessert. I’ve got just about the best thing ever pushing and shoving for a spot on your summer eats agenda.
It involves juicy as heck peaches. Sweet summer strawberries. Buttery-moist cake. HUGE piles of crumb topping weighing everything down. <<< all piled into one glorious strawberry peach crumb buckle.

Literally. THIS is like summer in a pan right here and you sure as heck will have no self-control around this goodness.
And you know what? It’s so freaking fantastic you won’t even care.

To start off, let me educate you a little bit on a buckle. Not quite like a crisp and not quite like a cake either. It’s a little mish-mash of both of them and it is quite incredible. Check it out, THREE layers –>
- Cake layer. It’s just your basic coffee cake dough with all da cake basics like sugar, eggs, flour, etc. Simple, buttery, moist and GOOD.
- Fruit layer. Find the juiciest peaches and strawberries you can get your hands on and toss them with sugar and lemon juice.
- CRUMBBBBBS. There’s a lot of it here because a buckle needs it so the cake and fruit layer “buckle” under the weight of the crumb topping. Zero complaints here in streusel-lover land.
This is real life, guys. All of this is what you get in this strawberry peach crumb buckle and excitement just goes with the territory.

PSA: if you can’t give up the ice cream for this, my pro tip is to compromise and put a big ol’ scoop on top of a thick slice of warm strawberry peach crumb buckle. TO DIE FOR.
Welcome to your summer bliss. ♥
