As soon as strawberry season starts, loads of strawberries regularly end up in our shopping basket – whether at the supermarket or the farmers market. Most of the time, we simply snack on the red berries as they are. Fresh, sweet strawberries are just perfect for that. You can also use them for baking, of course. Our Strawberry Oatmeal Crumble Bars are just one of many examples here. Really delicious little sweet treats where strawberry flavors really shine!
Traditionally, in our family, the first thing we’d usually make with strawberries is a simple Strawberry Cake with a light sponge base and a layer of vanilla custard. Grandma loved it, and this type of cake is still very popular with us today. Grandma and Mom typically used a ready-made base from the supermarket because it’s quicker, but we generally bake the cake base ourselves. If you happen to have a special strawberry cake baking tin lying around, you’ve got to use it, right?
Anyway. This year we broke with traditions and tried something new – the usual strawberry cake is just coming a little later in the season. And what can I say? A great decision! The little strawberry bars are a great addition to our already existing strawberry recipes. They turned out to be really delicious!
Of course, the fact that the Strawberry Oatmeal Crumble Bars taste so good isn’t because of the strawberries alone. Sure, they make up a large part of the flavors, but it’s the combination with the oats and sweet streusel topping that makes them such a treat!
Compared to a sponge cake, these crumble bars are much easier to prepare. For a sponge cake, you need either a food processor or a hand mixer – something to whisk egg whites. Or maybe a strong arm, a whisk and some patience, because the egg whites for the batter need to be whipped until stiff peaks form. That takes a while. For the streusels, you simply mix all the ingredients in a bowl – you can do this with a hand mixer or simply with a wooden spoon or rubber spatula. That’s considerably easier and less time-consuming.
If you don’t have oat flour on hand, you’ll first need to grind some rolled oats in a blender to get fine oat flour – that would be a kitchen machine you require as well… Assuming you want to follow the recipe to a T, but you don’t have to. If you don’t have a mixer or perhaps don’t have quite enough rolled oats at home, you can easily replace the ground oats in the recipe with regular flour. A few rolled oats in the crumble topping would be nice, though. If you read the recipe below more, you’ll understand what I mean.
Apart from that, crumble bars are really easy to make. The streusels you prepare are for the base and the topping as well – the fresh strawberries nestle comfortably in between. You can probably see that quite well in the photos. Once the streusels and strawberries are nicely layered, the baking tin is ready for the oven, and after about 35-40 minutes, the crumble bars are done. They need to cool down for a while and chill in the fridge as well for some time, but unfortunately, that’s part of the process… Nobody wants their crumble bars to crumble and fall apart when you cut into them, right?
Well… get started with the streusel topping and the strawberries, then enjoy the result in the sunshine with a coffee or tea. If you like simple and quick-to-do strawberry recipes, you should also check out our Easy Strawberry Tarts made with puff pastry. They’re quick to bake and simply divine with a dollop of whipped cream on the side!
Of course, you can also make something a bit more elaborate with strawberries – our Strawberry & Raspberry Layer Cake is an excellent example of that. But once you’ve tried that delicious cake, you’ll find the effort absolutely worthwhile. The cake is simply amazing!
INGREDIENTS / ZUTATEN
(9 crumble bars)
For the streusels:
7 oz. (200g) all-purpose flour*
3.5 oz. (100g) ground rolled oats*
3/4 cup (150g) sugar (fine)*
1/2 tsp. vanilla powder*
2/3 cup (150g) butter, cold
1 large egg
plus 3 tbsp. rolled oats*
For the filling:
17.6 (500g) fresh strawberries, diced
2 tbsp. sugar (fine)*
1 1/2 tbsp. cornstarch*
1/2 organic lemon, zest & juice
1/2 tsp. vanilla extract*
(9 Crumble Bars)
Für die Streusel:
200g Mehl (Type 405)*
100g Haferflocken*, gemahlen
150g Zucker (fein)*
1/2 TL Vanillepulver*
150g Butter, kalt
1 Ei (L)
plus 3 EL Haferflocken (Feinblatt)*
Für die Füllung:
500g frische Erdbeeren, in Stücken
2 EL Zucker (fein)*
1 1/2 EL Speisestärke*
1/2 Bio-Zitrone, Abrieb & Saft
1/2 TL Vanille Extrakt*
DIRECTIONS / ZUBEREITUNG
1. Preheat the oven to 180°C (350°F). Line a 23x23cm square baking pan* with baking parchment, grease lightly and set it aside.
2. Blend the rolled oats (100g/3.5 oz) in a food processor to get oat flour/finely ground oats. Add them together with the flour, sugar, and vanilla powder to a large bowl and mix to combine. Next, add the butter in small pieces as well as the egg, and mix everything until you get different-sized streusels – we normally do that by hand. Transfer about 2/3 of the streusels to the prepared baking pan and press them down to get an even layer. Bake in the preheated oven for about 15 minutes.
3. While the base is in the oven, wash, dry, and cut the strawberries into small pieces. Mix sugar and cornstarch, then add it to the strawberries along with the lemon zest, juice, and vanilla extract. Mix until well combined. Let the strawberries marinate for a few minutes.
4. Remove the pre-baked base from the oven and spread the marinated strawberries evenly on top. Mix the remaining streusels with the 3 tbsp. of rolled oats and sprinkle them all over the strawberries. Bake the crumble bars in the preheated oven for about 35-40 minutes. The strawberries should bubble here and there, and the streusels should have a golden brown color. Remove from the oven and cool down on a wire rack. When cooled, place in the fridge for at least 1 hour.
5. Remove the crumble bars from the baking pan by lifting them out with the baking parchment. Cut into nine bars/squares (or more, if you prefer them smaller). Dust with confectioners’ sugar to your liking before serving.
1. Den Ofen auf 180°C (350°F) Ober-/Unterhitze vorheizen. Eine quadratische 23x23cm Backform* mit Backpapier auslegen, leicht einfetten und zur Seite stellen.
2. Die 100g Haferflocken für die Streusel in einem Mixer zu feinem Mehl verarbeiten. Zusammen mit dem Mehl, Zucker und Vanillepulver in eine große Schüssel geben und vermischen. Die Butter in kleinen Stücken und das Ei dazugeben und alles zu Streuseln verarbeiten – geht am schnellsten mit den Händen. Etwa 2/3 der Streusel in die vorbereitete Backform schütten und zu einer glatten Schicht zusammendrücken. Für etwa 15 Minuten im vorgeheizten Ofen backen.
3. Während der Boden vorbackt, die Erdbeeren waschen, trocknen und in kleine Stücke schneiden. Den Zucker mit der Stärke vermischen und dann zusammen mit Zitronenabrieb, Saft und Vanille Extrakt zu den Erdbeeren dazugeben und alles gut vermengen – ein paar Minuten stehen lassen.
4. Den vorgebackenen Boden aus dem Ofen nehmen und die marinierten Erdbeeren gleichmäßig darauf verteilen. Die verbliebenen Streusel mit den 3 EL Haferflocken vermischen und dann auf die Erdbeeren streuen. Im vorgeheizten Ofen für etwa 35-40 Minuten backen. Die Erdbeeren dürfen hier und da blubbern und die Streusel sollten eine goldbraune Farbe bekommen haben. Aus dem Ofen nehmen und auf einem Kuchengitter abkühlen lassen. Danach dann noch mindestens 1 Stunde in den Kühlschrank stellen.
5. Die Crumble Bars mit dem Backpapier aus der Form herausheben und dann in neun (oder mehr, wer es kleiner mag) Stücke schneiden, nach Belieben mit Puderzucker bestreuen und servieren.
