You can use a ContentControl to display your DataTemplate. Another idea, which I prefer in this case, is to use styles. Below code shows hot to do both.

<Window x:Class="Test.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:Test="clr-namespace:Test"
    Height="300" Width="300">

    <Window.Resources>

        <Test:CurrencyDisplayConverter x:Key="CurrencyDisplayConverter" />

        <DataTemplate x:Key="MaskNormalBackgroundTbxDT">
            <TextBlock TextAlignment="Right" VerticalAlignment="Center" 
            TextWrapping="WrapWithOverflow"  
            Text="{Binding Converter={StaticResource CurrencyDisplayConverter}, ConverterParameter=true}" />
        </DataTemplate>

        <Style x:Key="MaskNormalBackgroundTbxStyle" TargetType="TextBlock">
            <Setter Property="TextAlignment" Value="Right" />
            <Setter Property="VerticalAlignment" Value="Center" />
            <Setter Property="TextWrapping" Value="WrapWithOverflow" />
            <Setter Property="Text" Value="{Binding Path=Amount, Converter={StaticResource CurrencyDisplayConverter}, ConverterParameter=true}" />
        </Style>

    </Window.Resources>
    <StackPanel>

        <ContentControl
            Content="{Binding Path=Amount}" 
            ContentTemplate="{StaticResource MaskNormalBackgroundTbxDT}" />

        <TextBlock 
            Style="{StaticResource MaskNormalBackgroundTbxStyle}" />

    </StackPanel>

</Window>
