Effortless Amish Oatmeal Rhubarb Bars (Print Version)

# Ingredients:

→ Oat Crumble Layer

01 - 110 g packed brown sugar
02 - 1.5 g baking soda
03 - 1.5 g salt
04 - 115 g unsalted butter, softened
05 - 95 g all-purpose flour
06 - 240 ml old fashioned oats

→ Filling with Rhubarb

07 - 2.5 ml vanilla extract
08 - 30 ml water
09 - 12 g heaping cornstarch
10 - 150 g white sugar
11 - 200 g chopped rhubarb

# Instructions:

01 - Set your oven to 175°C first. Line up your 20 x 20 cm pan with parchment or grease it well.
02 - Toss together the brown sugar, oats, flour, softened butter, salt, and baking soda in a medium bowl. Use your hands or a fork to mix it into little crumbly bits.
03 - Dump rhubarb, water, cornstarch, and sugar into a pot. Stir as you heat over medium. Let it bubble for about 5–10 minutes until the rhubarb is soft and thickened up.
04 - Take your pot off the heat and stir in the vanilla. Let it stand for 10 minutes so it can thicken and cool a bit.
05 - Take out about 2/3 cup of crumb mix and save it. Push the rest into the bottom of the pan to make an even layer. Try not to leave any spots open.
06 - Spread the rhubarb mixture all over the oat layer, making sure it covers every corner.
07 - Sprinkle the crumb mix you set aside across the rhubarb so it covers most of the top.
08 - Slide the pan into the oven. Bake 30–40 minutes until you see a golden crust on the base and the top holds together.
09 - Let the whole thing cool off right in the pan. Once it's cool, cut it into squares and dig in.

# Notes:

01 - If you like things smoother, take a blender to the rhubarb filling before building the bars once it cools but isn't thick yet.
