Sweet and tangy, these triple layer Raspberry Streusel Bars are perfect for berry lovers. With a thick layer of raspberry filling wedged between a buttery oatmeal streusel these soft, chewy squares are a must-taste cross between a cookie and a fruit crumble.

It took me three days to wake up this morning. If it weren’t for the fact that a pan of raspberry streusel bars were waiting for me in the refrigerator I would’ve slept until noon. Having dessert for breakfast was just enough incentive to drag my tired ass out from under the covers.

Before you judge my eating habits, not only are the dessert bars made with real raspberries but the streusel’s main ingredient is oatmeal. Let’s just call this breakfast “healthyish” and leave it at that, m-kay? Regardless of raspberry streusel bars’ place at the breakfast table, eating them in moderation for any meal is what’s important.

I say this with a streusel stomachache, yet I regret nothing. Instead, I applaud myself for having the foresight to make these thick, juicy squares in advance because the alternative would’ve been starvation pains.

While I consider signing myself up for Overeaters Anonymous, just let me say this recipe’s so simple to prep that it barely takes twenty minutes and most of that time is defrosting frozen berries. Plus, the streusel is the absolute best because it doubles as the bar’s base and topping. Minimal effort and minimal fuss makes these bars one of my berry favorite recipes.

Bursting with sweet raspberries these triple layer bars are ultra delicious. Serve them for breakfast, brunch or stuff one in your purse for a late afternoon snack. There’s literally no wrong time to overeat these soft, chewy raspberry streusel bars.

Before sharing the recipe for Raspberry Streusel Bars, here are a few tips and tricks to help you out:

Ingredient Tips

This recipe calls for frozen raspberries. I have not tested it with fresh berries but if you’d like to substitute fresh for frozen be sure to add raspberry jam to thicken.

Frozen raspberries must be thawed, drained and thoroughly patted dry with paper towels before using.

Recipe Doubling Tips

This recipe can be doubled then baked in a 9 x 13 pan.

How to Store Raspberry Streusel Bars

Place raspberry bars in an airtight container then refrigerate up to 5 days.

Can you freeze streusel bars? Yes! Simply place raspberry bars in an airtight container then freeze up to 3 months. Thaw overnight in the refrigerator before serving.
